Hello
I'm making an assumption here. It seems like a shared host group was used, when the volume got provisioned?!
This is the only case where I can see this happening. If this is as I suspect, then yes it would unpresent to all the servers in the shared host group if removed from the host group this is true for both HCS and Administrator.
You should not used shared host groups, each server should be it's own entity for this reason. Can you maybe show the volume in the host group and confirm that it is the case?
You have 2 options in this case depending on what you want to do:
- Do you want to unpresent all the volumes to one of the servers? If so, you go into the host groups in administrator(by going to the storage Array > Host groups) and remove the WWWN of the host from host group. But be careful, as this will unpresent ALL the volumes from that host group to the server.
- If you want to fix this, you'll have to do it path by path, and hope the failover works, best would be in a maintenance slot(since you can only have one WWWN one a port at a time in a host group). You can also possibly zone some new ports and fix this on the new ports and then delete the host groups on the old ports to complete the cleanup.
