How to check LUNs mappings are still intact/mounted after maintenance
We have hundreds of LUNs being mapped to numerous
ESXi hosts (running Windows, Redhat & Solaris x86) VMs.
I heard from my old-time colleague we have Redhat KVM
(I suppose this is a hypervisor) too.
After one of the monthly maintenance to upgrade firmware
of Brocade encrypted switches, a number of LUNs went
missing (or no more mounted by the hosts). I don't quite
know the details but I heard about 30% of the LUNs were
no more mounted by the hosts & need to be manually
re-mapped (or LUNs re-presented)
Is there a quick way to verify? Just by issuing a brocade
command (we have 8 Brocade switches) before the
maintenance & after the maintenance & then compare?
What's the FOS Brocade command? (configshow or
supportshow or ?)
We'll need this quick check for the long run
