Steps / sequence to remove the symdevs assigned to a windows host?
Hi Folks ,
Is there particular steps / sequence to remove the symdevs assigned to a windows host?
thanks in advance
Rajesh
Stop I/O to each LUN that's going to be removed.
Remove drive letter.
Unmask LUN.
Rescan on the Windows host or reboot to get a clean host without any remaining pointers to the old drives.
Unmap the SymDEV / META, but that's up to your specific environment. some companies leave unused LUN's attached to the FA's for later reuse. I always unmapped them.
Clean up your documentation.

Thanks RRR ,
Is this also same if i want to remove an entire storage( Array ) from a windows host . Suppose in windows host we not assigned any drive letter to a physical drive , is that safe to unmask & remove the zones ? Is there any method to delete a physical drive from disk manager?
Thanks in advance
Rajesh

if drive letter was never assigned, there is really nothing to delete ..you could delete partition if there was one. Your steps look good:
1) unmask
2) clean PowerPath (powermt check)
3) unmap from FA
4) unzone
