Caveats Send documentation comments to [email protected] • CSCse31881 Symptom: If there are IP over Fibre Channel (IPFC) interfaces configured on an SSM, you might experience issues if you downgrade from SAN-OS Release 3.x to Release 2.x. Workaround: This issue is resolved. • CSCsg19303 Symptom: Graceful shutdowns of ISLs are not supported for IVR traffic. Workaround: This issue is resolved. • 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: This issue is resolved. • CSCsk87502 Symptom: If an NASB configuration in a VSAN is destroyed while a target discovery is pending, the NASB process fails. Issue the show nasb vsan x command on the SSM to view the target discovery in the Pending state. Workaround: This issue is resolved. • 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: This issue is resolved. • CSCsl15511 Symptom: On the MDS 12-port, 24-port, and 48-port 4-Gbps Fibre Channel switching modules, and on the 4-port 10-Gbps Fibre Channel switching module for downgrades from 3.2(2c) to lower versions, if fcdomain persistency is disabled, F ports may not come up after a shutdown or no shutdown or a link flap. Workaround: This issue is resolved. • CSCsl17944 Symptom: During an MDS 9222i switch reload, the connection from the management port (mgmt0) to the Gigabit Ethernet interface goes down. When the connection comes back up, the Gigabit Ethernet interface doesn't go into forwarding mode until 30 seconds later. The Fabric Manager server is not able to communicate to the MDS 9222i switch through SNMP during this 30 second window. Workaround: This issue is resolved. • CSCsl42571 Symptom: SNMP timeouts occur when a AAA user ages out. By design, a AAA user is aged out every hour on a switch for security reasons. If a large fabric is discovered using a AAA user and a Performance Monitoring (PM) collection is added for such a fabric, a number of SNMP requests (related to the discovery or PM statistics collection) could time out. When a user views the PM statistics charts (in the Performance tab in the web client), the charts are not seen as continuous. Workaround: This issue is resolved.
