Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m New MIBS The following new MIB is included in Cisco MDS 9000 SAN-OS release 3.2(2c): • CISCO-SME-MIB MDS Authentication Mode As of SAN-OS Release 3.x, Cisco Fabric Manager required users to log in to the Fabric Manager server and the switches in the fabrics. This resulted in a two-step login process.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Deprecated iSCSI Features The following iSCSI features are no longer supported in Cisco MDS 9000 SAN-OS release 3.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • SPAN—1 session maximum Cisco MDS 9222i Multiservice Modular Switch and Cisco MDS 9000 18/4-Port Multiservice Module The Cisco MDS 9222i Multiservice Modular Switch and the Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4) support one iSCSI forwarding mode that is equivalent to store-forward on the MPS-14/2 module.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m CWDM SFPs The 2-Gbps CWDM SFPs do not have have a maximum speed set in memory and they negotiate to 4-Gbps on modules that support the higher speed. As a result, the link comes up and appears to work, but then becomes disabled and connectivity problems occur. To correct this problem, both sides of the connection must have their speed hard coded to 2-Gbps.
Limitations and Restrictions Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m QoS on an MDS 48-port Fibre Channel Module Due to possible differences in parts per million between the MAC ASICs on both sides of an ISL link, there is a potential throughput issue when running QoS over an ISL on an MDS 48-port Fibre Channel module. Specifically, the user may not see traffic throughput that follows the programmed QoS ratios.

Workaround: This issue is resolved. • CSCsk86748 Symptom: In rare circumstances, a Cisco MDS 9000 Supervisor may unexpectedly reload. This can trigger a Supervisor switchover, or a complete switch reload in the case of non-HA platforms.

Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsk73370 Symptom: In SAN-OS Release 3.2(1), the user configuration is not restored after a reload. Workaround: This issue is resolved. • CSCsk88049 Symptom: When using NASB with the EMC Clariion Disk Library (CDL), after enabling or disabling NASB (that is in the same VSAN as the CDL) multiple times, a login to the CDL from the NASB initiator can fail. Workaround: This issue is resolved.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Open Caveats • CSCsg49151 Symptom: If you bring up more than one link at a time between two VSANs that have overlapping domains and at least one of the switches is SDV enabled, one link will become isolated. The other links will come up, even though the domains are overlapping.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m 3. • Readvertise the withdrawn domains using the ivr refresh command. CSCsk49634 Symptom: In rare cases, an FCIP link might flap on a network with high latency and a consistently high loss rate. Workaround: None.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m This issue has no effect on functionality. However, debug messages and syslogs from the MDS switching modules have incorrect timestamps if the time zone is configured on an MDS switch. Workaround: None. • CSCsg19303 Symptom: Graceful shutdowns of ISLs are not supported for IVR traffic.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsk35951 Symptom: In a configuration with a PortChannel with FCIP members and write acceleration in use, if IVR NAT is enabled on one end of the PortChannel and not enabled on the other end, then traffic over the FCIP tunnel might fail. Workaround: Enable IVR NAT on both ends of the PortChannel or disable it on both ends.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsk95241 Symptom: If you use JDK instead of JRE on Solaris, you might encounter a problem trying to install Device Manager from a web browser. This can happen because the installer heap limit of 256 MB is not sufficient. Workaround: If you have this problem, save the jnlp link as file, increase the heap limit to 512 MB, and run javaws element-manager.jnlp at the shell prompt.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m • CSCsl34922 Symptom: Dual-fabric DMM migration jobs can not have one fabric running Release 3.2(1a) and a peer fabric running Release 3.2(2c) due to a signal message change. This may cause unexpected results during a DMM migration job validation, creation, start, and so on. Workaround: Run both fabrics with the same software image.
