Trying to recover after losing a disk

Take a trip on the wayback....

I have a JS12 Blade in a BC-S.  Two storage modules with 6 15k 300GB SAS drives each.  No RAID controller (standard SAS controller).  The JS12 has VIOS which is mirrored in rootvg - he seems to be OK. For IBM i I have two LPARs  1 LPAR running 7.2 has 4 disks but they are "double mirrored"; that is I have two sets of mirrored drives (don't ask) and LPAR 2 has one set of mirrored drives.  I have a 3rd LPAR running SUSE on a single drive.  I cannot connect at the moment to anything but VIOS and the AMM. Using the 5250 console fails to connect to either LPAR.  I swapped out the bad drive and I have a vague feeling that was the wrong thing to do.  But the biggest issue issue I that I cannot connect to either IBM i LPAR.

IVM shows that each LPAR has an SRC.  The 7.2 partition has SRC A6010255  and the 7.1 partition has SRC A6010255   When I looked up the 7.2 SRC it had this helpful note:

Explanation

Nice...except how do I find out the "failing item"?  When I click on the SRC link in IVM it gives me this:

Reference code:    A60C0255

Nice again....but where is the failing item indicated?   I know it's a hard disk that failed because the AMM told me that.  But I am not 100% sure it failed on one of my IBM i partitions.  It failed in the storage module but I am not sure the lost drive was used by IBM i.  Plus, the drives are mirrored so they should be degraded, not inaccessible....

Perhaps something else failed rather than only the drive....this guy is getting pretty long in the tooth.  So if someone could point me as to how to move forward on this adventure, I would appreciate it.
