RE: Moving disks from one iSeries to another

Rob, this is surprising to me - if the LPAR is not activated the cards
in the buses assigned to the partition will not be powered-on.  The only
thing that would be going on is that the drives would be spinning.

Now you *would* have problems if the drives were in a RAID set but had
no OS on them and you took them out, as they'd come in to the other LPAR
as DPH*** identifiers when you brought them online and you'd have to
initialize each one of them - that is a pain.

Wasn't he originally trying to remove drives first?  That's where the
problem comes in.  I recently did the several phone situation.  I was
removing drives from an inactive lpar on a 570 and adding them to an
active lpar on that same box.  The inactive lpar did not even have i5/os
loaded yet.  I had to actually load enough i5/os to go into DST and SST.

Then I could remove the drives I wanted.  Putting them into the live
i5/os partition concurrently was easy.

Re: Moving disks from one iSeries to another






OK This statement from IBM Seems pretty strange. I have installed dozens

if not hundreds of drives into machines over the years with nary a 
hitch. I do know that depending on how you add the drives to RAID sets 
you can end up with new sets where you wanted to add drives to existing 
sets.  Other than that though I'm just not sure where IBM is going with 
this.  With i5 hardware we now have the ability to add entire towers to 
HSL loops and with that up to 45 drives at a whack.

DId they say WHY they expected that you would be on the phone with
them??
