Re: Hypothetical: System Migration

You can move the whole drive set and this will work if you...

#1 Make sure you move other HW like NICs etc as required
#2 Bring the partition to standby and use the HMC to cfg the partition
#3 Be careful of the Virtual Ethernet addresses etc
#4 If you bring the disk controller with you or go to the same type
        then yo u can leave raid active.

Just as a side note on NON-LPAR'd systems
If the LIC and OS are correct, say an 810 with V5R3M5 Lic all the latest 
PTFs
You can do the same thing if the drives will fit the new system
Move drives, IPL fix resources and away you go.

Hypothetical:  System Migration







Hi folks, I've got a "friend" who wants to know if this would work.  :)

Needing to move an LPAR from a 550 to a 570+.  The current LPAR is 12x
disks, 8x of them are 35 GB, 4x are 70 GB.  They all reside in a 0595
and are attached to a 2780.  Two raid sets, the 35s and the 70s.

Location where LPAR is moving is a 5094 tower, final config will have
45x 35 GB drives and will consume the entire tower.  Ooodles of 2780s in
there (actually, 5580's - aux cache and all).

Here's the question, overly simplified:  Is it possible to remove the 70
GB units from the ASP (yes, there's enough room remaining on the 35 GB
units), break the RAID set, shut down LPAR, and then just move the 8x 35
GB drives to the 5094 tower, spin up to DST, start RAID, add the
remaining 37x 35 GB drives, start RAID on them, add to ASP, balance, and
off we go? 

Or do I need to do an unload-reload?
