Re: Partitioning a 525

Sharon:

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.......
