does any one knows how I can have different disks serial numbers for each lun that a host can see from a HSG80 RA8000 Storageworks array ?
The only way to use volume manager is to have several disk serial numbers and not the same, I tried lun paths thru different ports but the result is the same.
Thanks in advance
Solved! Go to Solution.

Anyway, I think you are looking at the wrong place, because different units do have different ids at some certain place - else Tru64 Unix could not work with the HSG.

SolutionIn that case, your operating systems are looking into SCSI inquiry page 80(16), the 'Unit serial number page'. This is where the controller serial number is reported.
The HSG (and other controllers like MSA and HSV) put a uniqe identification for each LUN (sometimes called LUN WWN/WWID) into page 83(16), the 'Device identification page'.
There is *nothing* on the HSG where you can change this behaviour.

Re: RA8000 HSG80 - All lun with the same serial number
I was afraid that in the HSG side there was nothing to do, and I expect that in the OS side I can't do nothing either :-(
Well, that's the reason that the HSG isn't supported with volume manager.
Thanks Uwe for your help one this ;-)
Best Regards
