Determining the Software Version
Note
To determine the version of the Cisco SAN-OS software currently running on a Cisco MDS 9000 Family switch, log in to the switch and enter the show version EXEC command.
Feature Set
This Cisco MDS SAN-OS Release 1.0(2) software is packaged in feature sets (also called software images) depending on the platform. The Cisco MDS SAN-OS software feature sets available for the Cisco MDS 9000 Family include Ethernet, Fibre Channel (1 Gbps and 2 Gbps), SNMP, and IP packets.
New Features in Release 1.0(2)
SAN-OS Release 1.0(2) is a maintenance release for switches in the Cisco MDS 9000 Family. See the "Caveats" section for details on closed and outstanding caveats and limitations.
Boot Loader Upgrade for the Active Supervisor Module
SAN-OS Release 1.0(2) introduces changes to the boot loader upgrade procedure for the active supervisor module.
This procedure does not affect traffic and can be issued at any time.
Note
To initialize and verify the kickstart image in an active supervisor module, follow these steps:

Note
Limitations and Restrictions
The following limitations and restrictions apply to all switches in the Cisco MDS 9000 Family:
•
FCC
Fibre Channel Congestion Control (FCC) is a Cisco proprietary flow control mechanism that alleviates congestion on Fibre Channel networks. FCC reduces the congestion in the fabric without interfering with the standard Fibre Channel protocols. The FCC protocol increases the granularity and the scale of congestion control applied to any class of traffic.
Testing is in progress for this feature. It is not supported for this release.
Install Command
SAN-OS Release 1.0(2) does not support the install all command.
RADIUS
If the timeout values and/or the retry count of the RADIUS server is too large, you may not be able to login into the system if the RADIUS servers are down.
Be sure to have a reasonable timeout and retry count. The cumulative response or timeout latency from RADIUS servers should not be more than 50 seconds. For example, in the following configuration:
radius server timeout 5
radius server retransmit 3
radius server host A
radius server host B
The worst case cumulative response or timeout latency for this example is:
(5+1)*3 + (5+1)*3 = 36Add 1 (one) to the retransmit count before calculating the total count (number of tries = number of retransmits + 1).
Another option is to have multiple RADIUS servers to backup a server that has gone down.
Caveats
This section lists the caveats and corrected caveats for this release. Use Table 3 to determine the status of a particular caveat. In the table, "C" indicates a closed caveat, and "O" indicates an open caveat.
Closed Caveats
•
Symptom: Role deletion may result in a user with no privilege.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz40837
•
Symptom: The dir command ignores the server location of the active and standby supervisor modules and accepts both sup-1 and sup-2 as valid parameters in the following command because it is displaying the contents of the bootflash: directory.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz39137
•
Symptom: VRRP module sends the vrrpTrapNewMaster. It formats the VRRP master IP address in reverse order in the trap variables.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz38149
•
Symptom: During a fabric merge (two E or TE ports are joined), the E ports could go into isolation, if there is a conflict in the active zone set on the two sides of the fabric.
MDS switches allow you to get out of isolation by exporting the database. If an administrator shuts the interface when the export is in progress, it does not recover.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz25873
•
Symptom: Setting the clock with out-of-range values may not return an error in some cases. Instead, the clock sets a different value or returns an inappropriate error message.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz42206
•
Symptom: If a switchover happens while the image synchronization is in progress, the switchover can be delayed up to 12 seconds. As the image synchronization only happens after booting the standby supervisor, give enough time for the synchronization to complete before attempting to issue a system switchover command.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz39924
•
Symptom: If a PortChannel contains member ports from DS-X9032, configuring the auto port mode on a PortChannel causes all member ports (including member DS-X9016 ports if any) to move to the initializing state.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz40770
•
Symptom: On unplugging active supervisor module, a trap is sent with incorrect reason.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz34906
•
Symptom: When sources are shared between two sessions, the session delete command may cause residual SPAN configurations on the shared sources. Avoid configuring the same source in multiple sessions in this release.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz49739
•
Symptom: When all ports in a PortChannel are shut down, the egress configuration for a PortChannel is not cleared in a switch. The traffic is spanned a second time when the ports are brought up again.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz47813
•
Symptom: If an E port in a Cisco MDS 9000 family switch is connected to a B port, the E port does not come up.
Please use the following URL for further information: http://www.cisco.com/pcgi-bin/bugtool/onebug.pl?bugid=CSCdz16649
Open Caveats
•
Symptom: When VSAN interfaces (VNI) are present in a system, you may receive some extra RSCNs when a system switchover is performed.
Workaround: None.
•
Sympton: An error message in the log file occurs because the platform manager component passes the wrong parameter while responding to a SNMP query. In some cases, this results in the query not being responded to.
Workaround: Perform a refresh on Device Manager to clear the problem.
•
Symptom: When you copy a file from active bootflash: to standby bootflash: and if the space available on standby bootflash: is insufficient to store the copied file, the copy command may report a success even though the file has not been copied to standby bootflash:.
Workaround: Always verify if sufficient disk space is available on the standby bootflash: before attempting to copy a file from one bootflash: to another.
•
Symptom: When you bring down a range of FL ports, there is a delay of four (4) seconds. This problem does not affect switch operation.
Workaround: None.
•
Symptom: SyslogServerAddressType setting is not preserved across switch resets, when configured using the Cisco Fabric Manager tool.
Workaround: None.
•
Symptom: When a fcsDiscoveryCompleteNotify trap is received through the nlmLog table, the fcsVsanDiscoverName is missing.
Workaround: None.
•
Symptom: Using the Element Manager or the Fabric manager, administrators can download an image to slot0 eventhough there is no flash in slot0.
Workaround: None.
•
Symptom: FLOGI ACC(s) sent out on FL ports are not spanned.
If an FL port is configured as a SPAN source, the FLOGI accepts that leave this FL port are not spanned to the SPAN destination.
Workaround: None.
•
Symptom: If the standby supervisor bootflash does not have sufficient space for a new image, auto synchronization fails. This failure leaves a partial image file on the standby bootflash.
Workaround: Delete all unnecessary files from the standby bootflash and make room for the new image.
•
Symptom: In the Cisco Fabric Manager, when you right click on a standby supervisor module and select Reset, the standby supervisor module powers-down instead of power-cycling.
Workaround: To reset the standby module from the Cisco Fabric Manager, select the Reset Switch option in the Admin pulldown. In the resulting dialog box, click the Reset Standby button
•
Symptom: The show logging level command does not display the configured levels for some MDS services like system manager, RDL, and FLOGI.
Workaround: None.
•
Symptom: If automatic image synchronization is enabled, and the standby supervisor module is synchronizing the image from the active supervisor, the switch won't stop the user from issuing the reload command on the active or standby supervisor modules. This may result in a failure to synchronize the images.
Workaround: Be sure to allow sufficient time for the images to be synchronized before reloading a supervisor module.
•
Symptom: If the timeout values and/or the retry count of the RADIUS server is too large, you may not be able to login into the system if the RADIUS servers are down.
Workaround: Be sure to have a reasonable timeout and retry count. The cumulative response or timeout latency from RADIUS servers should not be more than 50 seconds (see the "RADIUS" section).
Another option is to have multiple RADIUS servers to backup a server that has gone down.
•
Symptom: When the switch boots for the first time and you configure the initial setup dialogue, or if you issue the write erase command and then reboot the switch, the setup process creates the configuration based on the input that you provide for the configuration. If a command execution goes wrong at this stage, it displays the following error:
Error: There was an error executing at least one commandPlease verify the running configuration of the switch.In some cases, this error is not reported. For example, if an IP address is configured on the network, the error may not be reported.
Workaround: Verify that the applied config is accurate by issuing a show running-config command.
•
Symptom: When you enter the IP address for the FC analyzer, save the configuration, and reboot the switch you will loose the remote capture configuration.
switch(config)# fcanalyzer remote ip-addressswitch# copy running-config startup-configswitch# reloadThis command will reboot the system. (y/n)? yWorkaround: To perform a remote capture on restart or on switchover remove and add the host to the remote host list.
•
Symptom: When a zoning configuration change is made while a switch is powering-up, some entries may be rejected and a lock busy error message is generated.
Workaround: Re-enter the configuration after the E-port comes up.
•
Symptom: SW-RSCN frames sent by the switch may contain non-zero values in the reserved field. While this field is ignored by the receiving Cisco MDS 9000 Family switches, other vendor switches may respond otherwise.
Workaround: None.
•
Symptom: Cisco MDS 9000 Family switches support multi-pid RSCN from 1.0(2). In some cases, it may send out more than one SW-RSCN, when the option is turned on for the same event (port_online).
Workaround: None.
•
Symptom: When interoperating using a Cisco MDS 9000 Family switch and a Brocade 3900 switch, the zonesets on the MDS switch and Brocade 3900 switch may be out-of-sync due to a non-standard timeout used by the 3900 device.
Workaround: None.
•
Symptom: Currently a boot variable image does not check platform compatibility.
This is an enhancement request. When enhanced, the image specified in the boot command will be checked against the platform to verify that the image can run on the current platform. That is, an MDS 9500 image runs on the MDS 9500 switch and an MDS 9200 image runs on the MDS 9200 switch.
Workaround: None.
•
Symptom: After rebooting and performing a switchover on a dual supervisor switch, it is possible that a VSAN may display an up operational state even if that VSAN may not contain any ports or if none of the ports in that VSAN are up.
This can cause the Fabric Manager to continuously try fabric discovery on this VSAN and to ultimately timeout with an error.
Workaround: Change the administration state of the VSAN to suspended and bring it back to active. Doing so will correct the operational state of the affected VSANs.
•
Symptom: CLI command output attachment in XML Call Home messages are not XML encoded. In most cases it does not cause problems, as the special characters (which should be used with appropriate encoding, for example: > or <) do not appear in CLI command output. In some cases where stack traces are attached (as a result of a process crash), the CLI command output may contain these characters. These characters break the XML parsing in the back end.
Workaround: Contact the Technical Assistance Center (see the "Obtaining Technical Assistance" section).
•
Symptom: When using the Fabric Manager on Solaris or Linux platforms, if you access a parent menu the submenus start disappearing. This is a known Java bug.
Workaround: For more details access the Java website: http://developer.java.sun.com/developer/bugParade/bugs/4470374.html.
•
Symptom: When the Fabric Manager or Device Manager is run through VPN or any NAT scheme, a generic error occurs while adding duplicate zone members from a VPN connection.
Workaround: None. If an error occurs while running through VPN/NAT, all errors will show up as generic errors without a detailed message describing the error.
