Old 01-29-2016
not sure if my last post went out, posting
I was able to issue the power command
Code:
# powermt display dev=all
Device(s) not found.

we are contacting EMC to get someone here to help us make a snapshot of the LUN and to correct the zoning on the LUN.

we will then try the power commands to see if this resolves the issue

thanks

if you like to take a harder way and don't want to speak with IBM support, just change PVID on your disk and import it again.

PVID in VGDA is 000b63ca2e698c7b.
PVID on your disk is 0006b23f7962b123.

1. Save your PVID from the disk
Code:
# dd if=/dev/hdisk6 of=/tmp/pvid.hdisk6 bs=16 count=1 skip=8

2. Find octal representation of your future PVID. If I didn't make a mistake it should be:
Code:
# echo "\00\013\0143\0312\056\0151\0214\0173\c" | od -x
0000000  000b 63ca 2e69 8c7b
0000010

3. Add 8 zeros and write PVID to the disk.
Code:
# echo "\00\013\0143\0312\056\0151\0214\0173\00\00\00\00\00\00\00\00" | dd of=/dev/hdisk6 bs=16 seek=8
1+1 records in.
1+1 records out.

4. unconfigure and find the disk again:
Code:
# rmdev -dl hdisk6
hdisk6 deleted
# cfgmgr

5. Check that PVID is right:
Code:
# lspv | grep hdisk6
hdisk6          000b63ca2e698c7b                    None

6. If it is right, try to import VG again.
Code:
# importvg hdisk6

IF YOU DO IT WITHOUT IBM SUPPORT, THERE IS A BIG RISK TO LOOSE THE DATA!
