AIX LUN ID mapping question

Hello,

We have AIX servers and LUN is mapped to both hosts, but how I can verify from both LPARs? I don't have access to VIO server, but I want to make sure that LUN is assisble from both server.

IF I do  lattr  -EL   hdiskX and if  the PVID numbers are same, it means  lun is shared in both servers?

If the volume in question already has a PVID and if this ID is the same on both LPARS then you can be very sure that it's the same "real" disk (LUN), because PVIDs are unique.
Instead of "lsattr" you can simply use "lspv", by the way.

Without such a PVID being present (and without the possibility to create one)  and without access to the VIOS it's impossible to assure that two given virtual entities actually represent the same real entity!
