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

Hi Pete

You should be able to do that using the HMC. I know I built a picture of a
system with 8 0595s and 3 partitions this way. It was a case of working my
way through the hardware properties on each one. You can do it unit by unit
and bus by bus. I think you should right click on the server and then click
the properties tab but I'm vague on that.

I also used SST to verify what I was seeing.

Inav works great for working out where individual units are using Graphical
view. I always try and tie Unit no, disk unit and serial into a worksheet so
I know exactly what I am moving where and Inav ties these together better
than SST (going backwards and forwards between work with disk units and
hardware lists is tedious)

Evan Harris

Thanks Jerry. I always forget about iNav. It presents an easier to read
picture but I still can't figure out where the "empty cage" is attached
(if at all). I may just stuff a drive in there and see if it shows up
as an unconfigured unit somewhere.

Pete,

I don't know about HMC, but System i Navigator has some "stuff" under

Configuration and Services/Hardware/Disk Units that might give you what you
want. You do need an SST id and password to access the Disk Units segment.

Thanks Kirk. That was what I needed.

(I may be needing Dr. Franken at this point) I was told by this
customer that the expansion unit was full. That is, there wasn't any
room to stick 5 additional drives into the unit. However, when I go to
the expansion unit itself and open each of the cages, there is one cage
that is completely empty and two others that have 5 slots open in
total. So, the question is: How do I find out what controller these
"cages" are connected to? I am guessing that they are allocated to the
production side but if I can see what is allocated to each partition, I
might be able to stuff these 5 drives into the remaining cage and add it
to the LPAR (if it hasn't been) and then just create a new parity set.

I can print out a rack config I guess but it would be great to see a
"map" and understand how the hardware is allocated to each LPAR. Is
there a way to do that? Can the HMC do that for me?
