Determining the Software Version
Note
We strongly recommend that you use the latest available software release supported by your vendor for all Cisco MDS 9000 Family products.
To determine the version of the Cisco MDS SAN-OS software currently running on a Cisco MDS 9000 Family switch using the CLI, log into the switch and enter the show version EXEC command.
To determine the version of the Cisco MDS SAN-OS software currently running on a Cisco MDS 9000 Family switch using the Fabric Manager, view the Switches tab in the Information pane, locate the switch using the IP address, logical name, or WWN, and check its version in the Release column.
Upgrading Your Cisco MDS SAN-OS Software Image
The Cisco MDS SAN-OS software is designed for mission-critical high availability environments. To realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend that you install dual supervisor modules.
You can nondisruptively upgrade to Cisco MDS SAN-OS Release 2.1(2e) from any SAN-OS software release beginning with Release 1.3(x). If you are running an older version of the SAN-OS, first upgrade to Release 1.3(x), and then upgrade to Release 2.1(2e).
Note
If you are upgrading to Cisco MDS SAN-OS 2.1(2e) from any prior SAN-OS software release, you should issue the copy running-config startup-config command immediatedly after you upgrade to Release 2.1(2e) and before you issue any other commands. The fix for caveat CSCei02126 that is included in this release removes any corrupted snmpTargetParamsName entries from the running configuration. But the startup configuration may still have the corrupted TargetParamsName entries. Therefore, it is mandatory that you issue the copy running-config startup-config command immediatedly after you upgrade to Release 2.1(2e) to clean up the corrupted snmpTarget entries from the startup configuration.
When downgrading from Cisco MDS SAN-OS Release 2.1(2e) to Release 1.3(x), you might need to disable new features in Release 2.1(2e) for a nondisruptive downgrade. Issuing the install all command from the CLI, or using Fabric Manager to perform the downgrade, enables the compatibility check. The check indicates if the upgrade can happen nondisruptively or disruptively depending on the current configuration of your switch and the reason.
Compatibility check is done:Module bootable Impact Install-type Reason------ -------- -------------- ------------ ------1 yes non-disruptive rolling2 yes disruptive rolling Hitless upgrade is not supported3 yes disruptive rolling Hitless upgrade is not supported4 yes non-disruptive rolling5 yes non-disruptive reset6 yes non-disruptive resetAt a minimum, you need to disable the default device alias distribution feature using the no device-alias distribute command in global configuration mode. The show incompatibility system bootflash:1.3(x)_filename command determines which additional features need to be disabled.
If you are upgrading from Cisco MDS SAN-OS Release 2.1(1x) to any image later than Release 2.1(2) and have IVR enabled, review CSCei88345 in the Cisco MDS 9000 Family Release notes for Cisco MDS SAN-OS Release 2.1(2b) for upgrade instructions.
Note
Refer to the "Determining Software Compatibility" section of the Cisco MDS 9000 Family Configuration Guide for more details.
Performing a Disruptive Upgrade on a Single Supervisor MDS Family Switch
Cisco MDS SAN-OS software upgrades are disruptive on the following single supervisor Cisco MDS Family switches:
•
MDS 9120 switch
•
MDS 9140 switch
•
MDS 9216i switch
If you are performing an upgrade on one of those switches, you should follow the nondisruptive upgrade path listed in this section, even though the upgrade is disruptive. Following the nondisruptive upgrade path ensures that the binary startup configuration remains intact.
If you do not follow the upgrade path, the binary startup configuration is deleted because it is not compatible with the new image, and the ASCII startup configuration file is applied when the switch comes up with the new upgraded image. When the ASCII startup configuration file is applied, there may be errors. Because of this, we recommend that you follow the nondisruptive upgrade path.
New Features in Cisco MDS SAN-OS Release 2.1(2e)
There are no new features available for this release.
Limitations and Restrictions
This section lists the limitations and restrictions for this release.
VSFN Compatibility
For the latest VSFN compatibility information, refer to the Cisco MDS SAN-OS Release Compatibility Matrix for VERITAS Storage Foundation for Networks Software.
iSCSI Proxy Initiators
No more than 250 iSCSI proxy initiator sessions can be active on an IPS port.
Caveats
This section lists the open and resolved caveats for this release. Use Table 3 to determine the status of a particular caveat. In the table, "O" indicates an open caveat and "R" indicates a resolved caveat.
Resolved Caveats
•
CSCeh51924
Symptom: SNMP service might stop and restart because of a corrupted snmpTargetParamsEntry in the snmpTargetParamsTable. This corrupted entry is created when there is a null string in object snmpTargetParamsName as its index.
Workaround: Enter a name in the snmpTargetParamsName with at least one character when creating an snmpTargetParamsEntry.
•
CSCei02126
Symptom: If snmpTargetAddrName and snmpTargetParamsName are set to NULL in the SNMP host/target creation, then the SNMP process crashes and may cause a switchover to the standby supervisor module.
Workaround: When using third party tools or any other SNMP tool, set snmpTargetAddrName and snmpTargetParamsName to non-NULL values.
•
CSCei91968
Symptom: In a fabric with more than one switch, CFS or syslog can crash because of a PSS-FULL condition. This happens because of memory leakage in the persistent storage service (PSS) records stored by the CFS module.
CFS internal distributions cause a PSS leakage during one of the following events:
–
An application registration and deregistration. (This is at the rate of 1 PSS record or 60 bytes per event.)
–
An ISL Link flap. (This is at the rate of two PSS records per CFS registered application. For 10 CFS registered applications, a 1000 flaps would cause a leak of about 1 MB.)
In a stable fabric, application and regular CFS distributions do not result in PSS memory leakages.
Workaround: None. A switchover will help in cleaning up these records but the usage of the partition remains the same (dev/shm partition). However, CFS will reuse the freed space for further PSS storage.
•
CSCsb90192
Symptom: The CFS process crashes while processing a discovery response containing null data.
Workaround: None.
•
CSCsc16506
Symptom: The following syslog message is displayed:
Transmit Flow Control is seen for too longfollowed by link flap of the affected port. This applies only in E port mode and TE port mode of operation on Storage Services Modules (SSM) (DS-X9032-SSM) interfaces and occurs only when class-F packets are dropped due to a timeout condition. Typically, the packet timeout happens when there is serious congestion in the network, forcing the packets to stay in the switch for more than the timeout period.
Workaround: Avoid configuring in E port mode or TE port mode on the Fibre Channel interfaces.
•
CSCsc95884
Symptom: The install all command may fail on an SSM when you downgrade from Cisco SAN-OS Release 3.0(1) to any SAN-OS 2.x release earlier than SAN-OS Release 2.1(2d) on a system with at least one SSM.
Workaround: Power down the SSM before you downgrade the SAN-OS software. After the downgrade, power up the SSM with the new boot variable set to the appropriate Release 2.x SSI image.
•
CSCsc23435
Symptom: In some cases, services modules with FCIP interfaces that are configured on a Cisco MDS 9216i Switch may experience an overflow of packets on their FCIP interfaces. The overflow of packets causes packet drops, resulting in an error log and a possible system reload. This symptom affects the following hardware:
–
8-port Gigabit Ethernet IPS Services module (DS-X9308-SMIP)
–
4-port Gigabit Ethernet IPS Services module (DS-X9304-SMIP)
–
MPS-14/2 module (DS-X9302-14K9)
–
MDS 9216i Switch (DS-C9216i-K9)
Workaround: None.
•
CSCsc24966
Symptom: The following commands can sometimes hang the terminal during execution:
•
show tech-support commands
•
tac-pac
Workaround: If you are connected through an SSH or Telnet session, shut down the session and restart a new one.
•
CSCsc28722
Symptom: Upgrading from a Cisco SAN-OS Release 1.3(x) image to a Release 2.x image can disrupt ongoing traffic because spurious RSCNs are generated during the upgrade. Hosts that have registered for the RSCN, using SCR, will receive these spurious RSCNs and hence the disruption. However, upgrading from Release 2.0(x) to Release 2.1(x) will not disrupt any traffic.
Workaround: Suppress the RSCNs on a per interface basis during the upgrade using the rscn suppress interface fc slot/port hidden command.
Note
This configuration must be removed right after the upgrade, otherwise hosts that are registered for RSCN will never receive any RSCNs from then on.
Note
This configuration will go into the running-config. Because the running-config will be saved to the startup-config during upgrade, ensure that the configuration is removed and saved after upgrading.
Follow these steps:
1.
Issue the show rscn scr-table command to identify the port registered for RSCN.
2.
Issue the show flogi database command to identify the Fibre Channel interface of the port.
3.
Issue the config t command to enter configuration mode.
4.
Issue the rscn suppress interface fc slot/port hidden command to suppress RSCNs on all affected interfaces.
5.
Begin the upgrade progress as you normally would.
6.
Issue the no rscn suppress interface fc slot/port hidden command to allow RSCNs on all affected interfaces.
7.
Issue the exit command to return to EXEC mode.
8.
Issue the copy running-config startup-config command to save the running-config to the startup-config.
•
CSCsc31424
Symptom: Issuing a no shutdown command on an interface causes the following message to display:
fc1/1: (error) port channel config in progress - config not allowedThe following steps may reproduce the problem:
1.
Remove a port from a PortChannel.
switch# config tswitch(config)# interface fc slot/portswitch(config-if)# no channel-group group-number2.
Cause a system switchover.
switch(config-if)# endswitch# system switchover
Note
This problem does not always occur.
Workaround:
1.
Configure a new PortChannel and add the interface.
switch# config tswitch(config)# interface fc slot/portswitch(config-if)# channel-group group-numberWhere the PortChannel group-number does not exist.
2.
Remove the new PortChannel.
switch(config-if)# exitswitch(config)# no interface port-channel group-number3.
Disable the interface.
switch(config)# interface fc slot/portswitch(config-if)# no shutdown•
CSCsc57865
Symptom: A device alias cannot be renamed using Fabric Manager. Fabric Manager is polling the description of the device and not the name or alias for the device.
Workaround: Use the CLI to rename the device alias.
•
CSCsc68084
Symptom: Fabric Manager generates the following exception in the Fabric Manager log when trying to activate a zone set:
java.util.AbstractList$Itr.remove(Unknown Source)This problem occurs under the following circumstances:
•
You activate a new zone set in a VSAN using the Fabric Manager zoning dialog
•
The existing active zone set is not null.
•
One of the configured zones has a common zone member with one of the active zones (with the same zone name).
Workaround: None.
•
CSCsc98796
Symptom: If tape acceleration is enabled and the FCIP link is under a heavy load, an FCIP link can flap when a status frame is returned from the tape device with a check condition. This includes expected check condition status frames such as the early warning for end-of-media frames.
Workaround: None.
•
CSCsd02008
Symptom: During certain timing conditions, such as when a disk takes a long time to register FC4-type and FC4-feature information, IVR may not propagate the FC4-type and FC4-feature information to other VSANs and the information is missing from the name server.
Workaround: Perform the following steps on all IVR-enabled switches before activating the IVR zone set:
1.
Use a hidden command to set an internal flag.
switch# config tswitch(config)# ivr knob set 0x42.
If the IVR zone set is already active, disable and reenable the disk interface.
switch(config)# interface fc slot/portswitch(config-if)# shutdownswitch(config-if)# no shutdownswitch(config-if)# exitswitch(config)#3.
Save the running configuration to the startup configuration.
switch(config)# exitswitch# copy running-config startup-config4.
Verify the correct propagation of the FC4-type and FC4-feature.
switch# show fcns database vsan vsan-id•
CSCsd21093
Symptom: Sometimes, IP-ACL show commands may time out and appropriate error messages are seen on the CLI screen. Also, DNS queries corresponding to IP addresses configured in ACL filter specifications are sent from the switch to the DNS server whenever a show ip access-list command is issued.
Workaround: No complete workaround for this problem exists. Partial workarounds include:
•
Disable DNS lookups on a switch using the no ip domain-lookup command in configuration mode. This command is a generic command that disables DNS lookups, which affects the IP-ACL manager and all the other IP services.Use this command with caution.
•
Selectively disable the DNS lookups before issuing IP-ACL show commands and turn it back on after the show command is completed.
•
CSCsd29338
Symptom: The port manager might crash and a switchover might occur when FICON is configured and the MDS switch is interoperating with a CNT device. This occurs when a port is UP, a link failure happens, and the remote node ID (RNID) retry timer is activated.
Workaround: None.
Open Caveats
•
CSCeh73149
Symptom: The VSAN suspend/resume operations facilitate network level reconfiguration and are not often used. The operations should not be used on a SANTap related VSAN.
Workaround: If VSAN suspend/resume operations must be used, first unprovision SANTap prior to using VSAN suspend/resume.
•
CSCeh92604
Symptom: Enabling IVR NAT on the same switch where write acceleration is enabled over a PortChannel with multiple FCIP links might result in frames not transferring from the source to the destination.
Workaround: Do not have all of the following on the same switch:
–
IVR NAT enabled
–
PortChannel of multiple FCIP links that can potentially carry IVR NAT traffic
–
FCIP write acceleration enabled
However, any two of the above three configurations are supported on the same switch.
Note
IVR in non-NAT mode can be configured with FCIP PortChannels and FCIP write acceleration on the same switch.
•
CSCei18830
Symptom: Removing zones from an active zone set may generate a system message that the zone activation has failed because of an Accept Change Authorization (ACA) failure.
Workaround: None required. The IVR retries the activation and eventually the zone set activation succeeds.
•
CSCei19822
Symptom: An active IVR zone set on the local switch is not propagated when the commit session contains any other configuration changes.
Workaround: For Cisco SAN-OS Release 2.1(2) and later, perform an implicit commit without any changes. In the case of a merge failure and the IVR zone set is not active on remote switches but is active on a local switch, issue an implicit commit from the local switch to propagate the active zone set to the remote switches.
For releases prior to Release 2.1(2), the workaround is different. Add either a dummy member to an existing zone or add a dummy zone with dummy members to the currently active IVR zone set, and then reactivate the IVR zone set. Then issue the commit command, which will propagate the active zone set to other switches.

Symptom: An iSCSI host cannot log in to one IPS port after many supervisor module switchovers.
Workaround: None.
•
CSCsc75056
Symptom: Installing an invalid license file may cause an MDS switch to reload.
Workaround: Recover the switch from the console port. Then request another license file from Cisco. Install the unaltered license file.
Note
Do not edit or modify an MDS license file as this makes the file invalid.
•
CSCsc76467
Symptom: The IPFC manager fails when it receives an FARP packet for a nonexistent VSAN interface. This situation may occur when a host bus adapter (HBA) on a host directly registers as an IPFC interface.
Workaround: None.
•
CSCsd41578
Symptom: When a port continuously flaps, the Fibre Channel Name Server may crash and cause a supervisor switchover.
Workaround: Use a different port or check the host bus adapter (HBA) port.
•
CSCsd45429
Symptom: When performing a switchover, upgrade, or downgrade, logs may be incorrectly synced between supervisor modules. As a consequence, the syslog process is left with some inconsistencies that may cause one or more of the following symptoms:
•
A process may fail while displaying logs for a show logging command. After three failures of the syslog process, the switch forces a switchover.
•
Certain small sections of the log may appear out of order, either preceded by or followed by broken log lines, or both. For example, a few lines referring to 2006 Jan 17 may appear embedded between other log lines that refer to 2006 Jan 20, with a broken line before and after the entry.
•
Null characters (ASCII code 0) may appear in the log. These characters cause empty lines to be displayed when using the show logging command and appreciably slow down the log output over slow console connections.
Workaround: Clear the logs immediately after performing a switchover, upgrade, or downgrade by issuing the following command as soon as the switchover, upgrade, or downgrade successfully completes:
switch# clear logging logfile
Note
When you execute the clear logging logfile command, old logs are lost. If you need to keep a copy of the old logs, redirect the output of the show logging command to a file before the switchover, upgrade, or downgrade to copy the output to a safe location.
•
CSCsd47064
Symptom: The Forwarding Information Base (FIB) process may fail if an IVR zone set push from the Fabric Manager fails because of an SNMP timeout and various switches send conflicting active IVR zone sets.
Workaround: There are two ways to address the problem:
•
Examine the output of the show interface mgmt 0 command to see if there is a duplex mismatch that may cause an SNMP timeout.
•
Use the ivr distribute command to enable Cisco Fabric Services (CFS) distribution for IVR zone or zone sets and the topology through Inter-Switch Links (ISLs).
•
CSCsd78967
Symptom: If you remove a port from a port channel or shutdown a member port of a port-channel, the ConnUnitPortStatus/State trap is not sent.
Workaround: None.
•
CSCsd79954
Symptom: A VSAN that is connected to a McDATA switch with interop mode 1 participates in IVR. The VSAN has devices that are zoned for IVR with a device with domain IDs not within the 97 to 127 range. A loss of connectivity between the hosts and storage devices that are zoned for IVR and the devices in a normal zone might occur.
Workaround: None.
•
CSCse65400
Symptom: If a module reloads or reinitializes on its own because of an error, and the port channel has one of its member ports on this module, in rare cases, the peer port of this member port will not forward traffic after the module comes back up.
Workaround: Issue the shutdown/no shutdown command sequence on the port channel. If the problem still persists, issue the shutdown/no shutdown command sequence on the affected ports.
•
CSCse89151
Symptom: If you have more than 800 zones in an active zoneset for a single VSAN, your MDS 9000 switch might reload if you move from basic zoning to enhanced zoning and then read the active zoneset information.
Workaround: Lower the number of zones in an active zoneset for a single VSAN to less than 800.
•
CSCsh27840
Symptom: While using an FCIP link for remote SPAN, it is possible that the FCIP link may flap.
Workaround: Do not use FCIP links for Remote SPAN.
•
CSCef56229
Symptom: If an iSCSI initiator is configured differently on multiple switches, iSNS might report more targets to the initiator than the initiator can access. An iSCSI initiator would get a target error if it attempts to establish a connection.
Workaround: None.
•
CSCeg27584
Symptom: Creating a role that has the VSAN policy "deny" requires an Enterprise License on the switch. If such a role is created on a switch that does not have the license, the switch exhibits different behavior when distribution is turned on as compared with distribution is turned off, as follows:
–
If distribution is turned off, creation of the role is rejected.
–
If distribution is turned on, creation of the role succeeds but the VSAN policy continues to be "permit."
Workaround: None.
•
CSCeg37598
Symptom: The iSNS server might crash when iSCSI is disabled and iSNS is enabled using Fabric Manager.
Workaround: None.
•
CSCeg53114
Symptom: WWNs assigned to iSCSI initiators by the system can inadvertently be returned to the system when an upgrade fails or a manual downgrade is performed, such as when an older iSAN software version is booted up without using the install all command. In these scenarios, the system can later assign those WWNs again to other initiators, which causes conflicts. This bug is a duplicate of CSCei17870.
Workaround: None.
•
CSCeh33548
Symptom: Tape devices can only be accessed over an FCIP tunnel in a PortChannel with write acceleration enabled if SID/DID based load balancing is used in the VSANs.
Workaround: Disable write acceleration or enable SID/DID based load balancing in the VSANs if you have tape device traffic going over an FCIP tunnel in a PortChannel.
•
CSCeh41099
Symptom: Protocol and port numbers specified in an IP-ACL assigned to an IPsec profile (crypto map) are ignored. In an interop between Microsoft's iSCSI initiator with IPsec encryption with Cisco MDS 9000 Series switches, if IPsec is configured in the Microsoft iSCSI initiator (also the IPsec/IKE initiator), the host IPsec implementation sends the following IPsec policy:
source IP - Host IP, dest IP - MDS IP,source port - any, dest port - 3260 (iSCSI), protocol - 6 (TCP).Upon receiving this policy, the protocol and port numbers are ignored and only the IP addresses for the IPsec policy are used. Thus, although iSCSI traffic is encrypted, non-iSCSI traffic (such as ICMP ping) sent by the Microsoft host in clear text is dropped in the MDS port.
Workaround: None.
•
CSCeh75500
Symptom: A device that interfaces with SANTap may request SANTap to create a session for an ITL that was previously requested, and ITL checking is not robust.
Workaround: Have the device validate the ITL and ensure that it does not send a request for a duplicate ITL.
•
CSCeh88814
Symptom: When SANTap is unprovisioned, the control virtual target (CVT) object is not getting cleaned up on the supervisor module.
Workaround: To ensure that cleanup occurs, first issue the no santap module slot-number appl-vsan vsan-id command to clean up the CVT, and then unprovision SANTap.
•
CSCei32317
Symptom: When configuring a remote SPAN (RSPAN), the Fibre Channel tunnel does not come up if it goes through more than one hop.
Workaround: Configure the Fibre Channel tunnel explicit-path option and list every IP hop between the source and destination.
•
CSCei57342
Symptom: If a link is isolated because of a fabric-binding database mismatch, a reactivation of the corrected fabric-binding database may not initialize the ports.
Workaround: Use the shut command followed by the no shut command to manually disable then enable the link.
•
CSCei58652
Symptom: When a reconfigure fabric (RCF) frames occurs on a VSAN, the ports may be left in a state where the fabric binding is incorrect.
Workaround: None.
•
CSCei71686
Symptom: If iSCSI is enabled before FCIP, then the qos command that is configurable under a FCIP interface is not available as an option. The reverse is true as well. If FCIP is enabled first, then the qos command is not an option for iSCSI interfaces.
Workaround: None.
•
CSCei86399
Symptom: A TACACS+ key that includes the less than (<) and greater than (>) characters fails when copied to an ftp server, and then copied back to the MDS switch.
Workaround: None. This issue has been resolved.
•
CSCin95686
Symptom: The RRD graph in the Performance Manager does not refresh on a web client opened in Mozilla or Netscape.
Workaround: Do not use a proxy server or the browser's Refresh button.
•
CSCin95789
Symptom: When you configure Cisco Traffic Analyzer to capture traffic on one or more interfaces on a Windows platform, the configuration web page might not show that the interface has been selected for traffic capture even though traffic capture on that interface is enabled.
Workaround: Check the logs to clarify that the correct interface has been selected.
•
CSCsb89732
Symptom: After an upgrade from SAN-OS Release 1.3(2a) to any release lower than SAN-OS Release 3.0(1), you may see errors like the following in the syslog file:
