Re: the server locked up the lun
You method has to be based on the redundancy, if the other paths could not work as you expected, for instance, the other paths may get failed for any reasons which you don't know anything about, by disabling one port could cause all luns down.
The best way would be to unlock that lun on the server side, but I just don't know about it.

Re: the server locked up the lun
1. disable port A,
2. if you culd release Lun, then
enable port A done. otherwise continue
3. disable port B
4. if you could release Lun, then
enable port B. done
From above steps, there is also possibility that once you enable port A, for any reasons, the host may lock the disk again through port A. If that'd be the case, we then really get stuck!

Re: the server locked up the lun
I would not have thought rmsf would work if it was still assigned to a volume group however...

Re: the server locked up the lun
As I said, I already run rmsf -H, and the device has been removed.
Either one or both paths hold the lun, so we would have to try both if one of them is not working.
