Consider to replace the both disks and the battery!

Hello Torsten,
thanks for the reply. Is there any procedure to follow before replacing the disks? as for the battery i "googled" the procedure to replace it.

Hi,

There are some FC60 documents to assist you. See the Service Guide and tips on changing the BBU and don't forget to reset the battery age after the replacement has been installed.

There are 2 problems:

THE FOLLOWING WARNING(S) EXIST:
- Array Enclosure Battery: CRITICAL

...

SCSI Channel:ID = 2:1
Enclosure = 0
Slot (0-based) = 3
Disk State = FAILED VIA MODE SELECT
Disk Group and Type = 0952F6005248FCF9B5 LUN
Capacity = 68.4 GB
Manufacturer and Model = HP 73.4G ST373453LC
Serial Number = 3HW0R4NH
Firmware Revision = HPC5

SCSI Channel:ID = 5:4
Enclosure = 2

The manual says about this status "The disk was failed using a host-initiated command."

I would try to change the status to up again:

amutil -d channel:id -rr channel:id

Hello Torsten,

could you clarify more about the usage of the proposed command as i will execute on a live and critical system:

amutil -d channel:id -rr channel:id
as in fact the manual pages of amutil does not mention the -d and -rr options specified above.

Thanks in advance

Using -D you can down a disk to a FAILED state (this was perhaps done before?), using "-d" you can set it to UP again. I would try this with the "failed" spare disk first and check again after this.

One more thing,
and the -rr option in :
amutil -d channel:id -rr channel:id
what is it intended for?

Re: FC60 Problem (help plz)

-rr changes the state of the specified disk to REPLACED. This will initiate a rebuild
copy-back to the disk if it currently be spared by a global hot spare. This is useful if the rebuild does not start automatically after replacing a disk.
