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 Error Type PhyPortLayer Port(s) Affected Error Description DSAP UUID Time : : : : : : : Minor error Fibre Channel 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18 0 (0x0) 0 (0x0) Mon Nov 16 10:07:33 2009 (Ticks: 4B012465 jiffies) All FC and FCIP interfaces go into a hardware failure state and the switch needs to be reloaded to recover.
PAGE 41
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 Symptom: The zone server fails the zone check for the host and virtual target with iSAPI, and then rejects the host’s PLOGI request. This happens because of the two-second delay between the PLOGI sent from host to the target, and because of the host port online RSCN. The issue also happens when a host goes down and comes back after a zone set activation.

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 Symptom: An IVR switch was stuck in the advertising state shortly after a zone set activation was received by IVR. The zone set activation was complete, but IVR remained stuck in the advertising state. Workaround: This issue is resolved. • CSCte46571 Symptom: The show cores command displays the timestamp of the core files, but does not include the year. Workaround: This issue is resolved.
