I upgraded a p620 this weekend from 4.3.3-09 to 5.1-03. I did not have
any problems with the CD.
The boot time and restore was normal.

I would try to get hold of another set of AIX CD's rather than making a
copy.

Subject: AIX 5 Upgrade CD problem

I am having some problems migrating a pSeries 6C1 from 4.3.3-10 to
5.1-03.

For some reason the cdrom on this server reads my AIX 5.1 cd extremly
slowly. Infact it can took upto 30 mins just to boot off the cd and go
into maintenance mode. Then when I actually started the migration, it
was going so slow that I estimated it would take 5 hours to update the
180 or so filesets that I have on this server. Anyway, the upgrade
failed, I dont know if this was due to the cd/cdrom so I had to restore
this server from a backup.

I inspected my AIX 5.1 cd1 and found a small faint scratch that perhaps
wsa causing my problem. So I burned a copy of cd1 and tried using
that,,,,,,same problem again although it seemed like the reading of the
cd was somewhat faster but I cancelled the upgrade because it was still
going to take longer than the maintenance window I had. So the next
evening I got another set of AIX 5.1 cds and again had the same problem.

I have another 6C1 that I migrated the week before and I also had the
exact same problems with this server reading the AIX 5.1 cds so slowly.
It took my three attempts to get this server to boot into maintenance
mode and do the upgrade. So I beginning to think that perhaps the 6c1's
have a problem.

Now the strange thing is as a test I used a 4.3.3 cd to boot this
server, and boom the maintenance menu loads up in about 2-3 minutes
which is the norm, so this only seems to be a problem with AIX 5.1 cds
and not the cdrom itself. Anyone have any ideas whats going on here or
experienced the same thing?

BTW, I updated the system firmware to the latest level prior to the
migrations.

I am beginning to think that I may have to use the alt_disk and NIM
method for migrating my 6C1, but that will a pain for me to setup.
