Re: Partitioning a 525

The firmware and HMC code levels must match, but since there is not an HMC today, chances are the firmware is updated with Group/Cumulative packages. A reasonable assumption would be that they are within striking distance of current.

The best way to ensure all the firmware and hardware PTFs etc are current is to load the latest cumulative and other groups to the system before changing the console out.

The HMC level can be checked by bringing it up and looking but honestly, I would just reload it from scratch anyway to be sure everything is set up cleanly.

How concerned should she be on firmware levels.

It is actually as easy as described. A couple of quick hint beyond what
has been discussed thus far.

1) Set up the HMC and get the console going on your system FIRST. That
is likely to be the hardest part since changing the console requires
some tinkering.
2) Make sure you get the RIO/HSL loops correct. Not getting that right
could cause performance troubles or the system may not work. You did
not say if there were any other chassis on the system. If not, make
sure the proper hardware in on the 525 to connect the loop in the first
place. If there are, there is a limit of 6 chassis on the loop.
3) The SPCN cables also need to be set up properly so study that.

It might be best if you have your IBM CE do the connections (you will
have to pay him) or a certified business partner.

One last thing. If you bring up your new LPAR and it gives you any
messages about wanting to add new disk units and such, STOP! You have
something configured wrong. If you stop at that point, you can correct
it without data loss, if you start the process to add the disk, it's
reload time.......

I can handle the software side and have nearly all of that sorted out.
It was the 595 rack move that I was concerned with. I understand what
you mean about "point". Now I have a better feel for what needs to be
done.

Just in case, I intend to have two complete backups on hand.
