Re: Disk upgrade with no downtime - possible? Follow up question

[Pete Helgren <Pete@xxxxxxxxxx>]

Running a system backup on the development partition at the moment so I 
don't have access to SST but with a little more sleuthing, I think I may 
have some good news.  Looking at the diagram and instructions on the 
inside door of the expansion unit and comparing it to what I see in the 
rack config on the production side, the diagram indicates that IOA #1 
controls the cages that are marked DB3-0, DB3-1 and DB3-2 on the 
diagram. Based on what I see in the Rack config, it looks like IOA 2 
(DB2) and 3 (DB1) are allocated to the production partition because I 
don't see any disks controlled by IOA #1 (DB3) in the production LPAR.  
I *think* the Planar ID in SST points to the IOA on the diagram but I 
won't be sure until the backup is complete and I can jump in with SST to 
look.

I went ahead and loaded up the empty cage with the 5 drives.  Hopefully, 
when I DO get a chance to run SST, I'll see the 5 drives as unconfigured 
and will be able to add them to their own parity set and add them to the 
ASP on the development partition.  I don't currently see the drives 
showing up in the production side in SST so I again am hopeful that dumb 
luck has prevailed and the one empty cage was attached to the 
development partition.

I'll know more in the morning.

Thanks again.

OK... Got to be carefull here... For i5 OS partitions at 5.4 and below, 
disk is allocated by the Disk Controller. ie All Disks on controller 'A' 
will be in the same i5 OS Partition. Depending on the card in use etc 
there may not be anymore slots available for this partition. So at this 
point  we need to know the system model, expansion model(s) and a 
rackcfg of this partition.
