Task:
Recently I was assigned a task to remove 10 old unused LUN from ESXi 5.0 Hosts.
Issue:
when I tried to detach first 3 LUN, it was successful but when I tried 4th LUN, task bar shows LUN detaching in progress for 30 Min's and Host Disconnected from vcenter.
After that I SSH to the host and tried to execute esxcli commands. but unfortunately the whole command module was not available I cannot execute any cli esxcli commands. I re-started the management network and tried to rejoin back to vcenter but all failed.
Temporary solution:
I informed all the server owner and got downtime to shutdown all the VM's and rebooted the ESXi Hosts and re-connected to vcenter
up on checking the logs it's shown as below

Solution: Up on checking VMware KB, it shows that this issue is not related to VMware and it's related to Powerpath.

I upgraded the Power path to latest version and now I can able to detach the LUN with out any issue.
