That makes a lot of sense.

I looked at the management partition and see that it has "Server SCSI" virtual adapters... one for each guest partition. The guest partition has a "Client SCSI" virtual adapter.

The guest partition's Client SCSI uses adapter id 7, it's server/client partition is Management, the partner adapter is 7, and it's not required.

The management partition's Server SCSI adapter is 7, server/client partition is SV2(7), partner adapter is 8, and it's not required.

Take a look at the config for each partition on the HMC and validate
that the virtual CLIENT SCSI adapter is tagged as your alternate
restart device.

I looked at the settings for the guest partition and in the "Tagged I/O" section, it's showing a load source of slot 7 / Virtual I/O, alternate restart Slot 7 / Virtual I/O, and console Slot 1 / Virtual I/O.

Can I assume this means that the client scsi that's in virtual slot 7 can be used as an alternate IPL device and the upgrade will use it if I select IPLSRC(D) when I do the PWRDWNSYS?

You can assume just that. As long as no other parttion is using it.
