Symptom
Possible Cause
Solution
iSLB configuration
not distributed to all
switches in the fabric.

Update switches to Cisco SAN-OS Release 3.0(1) or later.
CFS distribution is not enabled for
iSLB.
Enable CFS distribution for iSLB. Use the
show cfs
application name islb
CLI command to determine if CFS
distribution is enabled. Or use the
show cfs peers name
islb
CLI command and check to see if any switches are
missing from the output.
Use the
islb distribute
CLI command to enable CFS
distribution.
