Recovering a 'missing' pv

[MHThomas]

Hope somebody can help, it's Christmas and I'm all alone in the office and an Engineer has killed one of our production AIX servers (by removing the wrong disk from an SSA array).
The Engineer physically re-added the disk and I have rebooted and can 'see' the disk, but the filesystems on it can't be mounted due to a problem with the superblock. If i do an lspv -l hdisk5 it gives a status of 'missing'.And a df of a filesystems on the missing disk I get the following:
/dev/maillennium
df: /maillennium: There is an input or output error.
And if I try and mount the filesystem I get the following
mount /frep
Unable to read superblock (TERMINATED)
Unable to read superblock (TERMINATED)
mount: 0506-324 Cannot mount /dev/frep on /frep: There is an input or output error.

Have I any hope of an easy resolution.

Happy Christmas BTW

did you try with a "cfgmgr"?

Looks like a phisical isssue.
I would first try to dd from the disk to ensure it's readable.

dd if=/dev/hdisk5 bs=1024 count=2

A superblock can possibly be reconstructed,but this is later.

Long live king Moshiach !
