I have an IBM 9110-51A p Series Server with AIX 5.3.
It has 2 scsi hard disks hdisk0 and hdisk1 (and 4 on disk array).
hdisk1 is is "Defined".
When hdisk1 began "defined" i have a new one unknown disk "available" which called hdisk6.
The left led of the case of hdisk1 on the server is green, the right is off.
When i run

lsvg -p rootvg

I get "hdisk1 removed".
I cant take a response from hdisk1 from the #diag because it shows me the hdisk1 as missed (M).
I have HMC where i can get more infos .
Can someone help me find and fix the problem so hdisk1 become again available?
What i have to do?
I have a new one IBM scsi hard disk if needed.

Thank you in advance.

It sounds like hdisk1 failed and was replaced by hdisk6 without removing the ODM definition for hdisk1 first.

If this is what happened, rmdev hdisk6, rmdev hdisk1. Then, cfgmgr and the new replacement disk should show up as hdisk1. hdisk6 would be gone.

You may have to force hdisk1 out of rootvg before you can rmdev it. And, you'd have to put the new hdisk1 back in rootvg after the cfgmgr.

Whenever you have a disk failure, you need to remove it out of whatever disk group it is in, rmdev it from the system and then replace it.

cfgmgr can't run at server and get an error.
When i saw a green led light at the front of hdisk1 i put it out and then i put it back in the server. Do you think this in and out from the server caused the hdisk6? (hdisk1 and hdisk6 have the same location code)
HMC show me an error for the hard disk.
Can you write me the steps i have to do? (check if hdisk1 is mirrored, create the same groups if i have to replace the hdisk1 with a new one so i will have again the server in the same state before disk failure)
I can give you any info from a command run at the server.

Thank you

Any idea what to do please?
These are the results from some commands (from one of two servers i have, which has the problem):
