Re: Trying to recover after losing a disk

I assume the disk is provided by the VIOS, if that is the case you have to
check the VIOS's filesystems / file based disks / mappings to check what is
dead.
lsmap -all will tell you what is mapped to what and from there we can work
out what is going on. It is weird you say that there are different disks
mirrored and for only one disk to kill everything. I think that it might
not be the case and maybe VIOS was providing disk based disks. lsmap will
tell us.

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
Contact was lost with the device indicated.
Response
Do not power off the system.
Perform the procedure indicated in the failing item list.
Failing Item
LICIP13

FI00500
FI00302
FI00301
AJDG301

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
Description: Contact was lost with the device indicated
Time stamp (UTC): 10/21/20 12:05:18 AM
Word 2: 0DB08062

Word 8: 6B220050
Word 9: B6005120

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.
