Kaps, here's the output of those three commands

As you can see there's no additional PVID.

The extendvg command is still displaying the same message as before.

OK so the disk is good. Try the -f flag (force).

Thanks everyone for your suggestions. In the end we got IBM involved and they identified a mismatch with the ODM and the VGDA on the disk. The remaining disk thinks that it is the only disk in rootvg, yet the ODM has 2 entries:

# odmget -q "name = 'rootvg' and attribute = 'pv' " CuAt

CuAt:
name = "rootvg"
attribute = "pv"
value = "001016cc9220d0de0000000000000000"
type = "R"
generic = ""
rep = "sl"
nls_index = 0

CuAt:
name = "rootvg"
attribute = "pv"
value = "001016cc923411e70000000000000000"
type = "R"
generic = ""
rep = "sl"
nls_index = 0

Use this to get things back in sync :
# redefinevg -d hdisk1 rootvg

then

# synclvodm -Pv rootvg

After this the extendvg and mirror commands work ok

Thats great ! Well done and thanks for sharing the way you solved it. You have helped a lot of others ..

Did IBM give you any idea how it must have happened ?
