We have already discussed on how to add an EMC storage to a Solaris box. Now we have a dead path on our system where the storage team has decommisioned. Here are the steps to follow on how to remove these dead paths from our system.
Check on your current paths
root@solaris# /etc/powermt display Symmetrix logical device count=20 CLARiiON logical device count=50 ============================================================================== ----- Host Bus Adapters --------- ------ I/O Paths ----- ------ Stats ------ ### HW Path Summary Total Dead IO/Sec Q-IOs Errors ============================================================================== 2304 ssm@0/pci@1f/lpfc@1 optimal 121 1 - 0 0 2305 ssm@0/pci@1f/lpfc@2 optimal 120 0 - 0 0
Remove the dead paths
root@solaris# /etc/powermt check Warning: CLARiiON device path c7t4d0s0 is currently dead. Do you want to remove it (y/n/a/q)? y root@solaris# /etc/powermt config root@solaris# /etc/powermt save
Verify if the dead paths are removed
