Failed mirror of rootvg AIX 4.3.3.0

[jthiessen]

This morning my mirror of rootvg failed. This is what happened so far.

-System shutdown (done because the drive bearing failed and I wanted to make sure that my AIX server was causing the problem.)
-When system restarted, hdisk1 showed as defined and missing. A new drive, hdisk6 had been created.
-Hard drive was replaced.
-Hdisk6 removed from AIX.
-Hdisk1 removed from AIX.
-System restart, Hdisk1 detected. (This was now the new HD)
-Used extendvg rootvg hdisk1 command.
-Tried to run mirrorvg rootvg hdisk1.
-Mirror seemed to succeed and fail, got several errors regarding failed synch.
-Issued lsvg -a rootvg. This showed hdisk0, hdisk1 and another disk that does not match configuration.

My theory is that this third disk is a "ghost" of the failed drive, however, I do not know how to remove this "ghost" from PDM. I was thinking of removing hdisk1 from AIX, then UNmirroring, then readding hdisk one to rootvg and attempting mirror again.
Does anyone have some insights?

Josh,

If you get the PVID of the failed disk just use:

reducevg rootvg <PVID of missing disk>

It seems that you did not remove the original hdisk1 from
the volume group, according to your steps above.

Thank you, I will try that command, although on the lsvg I saw 3 drives I think, hdisk0, hdisk1, and another disk that did not have an ID. I will try this and let you know how it goes.

Hey PSD, I tried what you said, but it won't delete the partition. It says the partition is stale. I guess I need to resolve that first, any ideas on resolving that?

Sorry to keep blabbing. It looks like I have resolved the issue. mirrorvg has been running for 10minutes or so, so I don't think it will fail. What I did was use chpv -vr to remove the defunct disc then varyonvg -n on rootvg. I am not sure if varyon was needed, but it seems to work now anyway.
