Caveats Send documentation comments to [email protected] Symptom: Following a reboot of an MDS 9513 switch running Cisco SAN-OS Release 3.3(2), both supervisor modules generated core files. The show cores command and the show system reset-reason command displayed the following output: switch# show cores Module-num Process-name ---------- ------------ 8 qos 7 qos PID --15671 4370 Core-create-time Sep 21 22:16 Sep 21 22:17 switch# show system reset-reason ----- reset reason for Supervisor-module 8 (from Supervisor in slot 8) --1) At 517868 usecs after Mon Sep 21 22:12:09 2009 Reason: Reset triggered due to HA policy of Reset Service: Service "qos" Version: 3.3(2) ----- reset reason for Supervisor-module 7 (from Supervisor in slot 7) --1) At 260648 usecs after Mon Sep 21 22:12:37 2009 Reason: Reset triggered due to HA policy of Reset Service: Service "qos" Version: 3.3(2) Workaround: This issue is resolved. • CSCtc48338 Symptom: On any of the MDS 9500 Series Director switches that have removable Supervisor 2 modules, a supervisor may reset when any one of the following commands is executed on the switch, or the same information is collected through Cisco Fabric Manager or Device Manager: • show hardware internal mgmt0 stats • show hardware internal eobc stats • show tech • show tech details • show tech-support • tac-pac In a dual supervisor switch, entering one of these commands will force a supervisor switchover. In single supervisor systems, the switch will reload. This issue does not affect switches with a nonremovable Supervisor 2 module, such as the MDS 9222i or MDS 9124. Workaround: This issue is resolved. Open Caveats • CSCsr85709 Symptom: Under certain conditions, the port manager can take a long time to respond to a port configuration, which can trigger a set-port-configuration failure. If this occurs, then the FCIP tunnel will not come up and will stay in a disabled state. Workaround: Enter a shut command, followed by a no shut command on the FCIP interface at either end of the FCIP tunnel.
