Hello, everyone,
I wanted to follow up on this issue with a big thank you for everyone's
assistance. I learned a great deal about the HMC and iSeries firmware
through this ordeal.
The bottom line is that we had a failed IOA Adapter card. It was not the
RAID card on which we replaced the battery cache. Apparently, when an IOA
card goes, a lot of stuff goes crazy. We had tape drives disappear, three
extra optical drives appear from nowhere AND move to the other partition,
and parity status require rebuilding on one of the partitions.
I really appreciate all your advice and free transfer of knowledge and
experience. Thanks again.
Best Regards,
Thomas Garvey

You really need to connect to HMC2, as HMC1 already has a new address, which
you don't necessarily know. If you go to option 30 off the front panel, you
will know what the HMC1 address is. You can set the HMC ETH0 to have be in
the same range and then get a connection.

Yep. However, the HMC was not talking to the iSeries. It only saw an
IP address of 10.0.0.254 and the Status for that was No Connection.
So, the HMC could not be used.
10.0.0.0/24 is one of the default subnets for a private subnet for HMC/FSP
communication.
This is why you probably didn't know it.
In a default configuration, the FSP receives it's IP Address from the HMC
through DHCP. If you power on the FSP before the HMC, the FSP may fail to
get a DHCP lease from the HMC, most likely leading to the problem you
described.
Plug your laptop into the HMC port on your i, use the fallback default IP
(192.168.2.147, if i remember correctly), log onto the ASMI and change the
FSPs IP Adress.
Alternatively, power down your i, unplug the power, replug the power, and
then the FSP should get a valid lease from the HMC.
