Thanks. We'll let you know when a new response is added.

Type the command on prompt WRKDSKSTS and press Enter,You will see the the disk status.

When you are in WRKDSKSTS press F11 “Display storage use” or “Display disk statistics” to see Protection Type and Status. This is a quick way to check for failed drives or a bad CACHE battery.

A bad CACHE battery will usually show up as DEGRADED.

This is what you don’t want to see:

--Protection--
Unit ASP Type Status
1 1 DPY FAILED
2 1 DPY UNPROT
3 1 DPY UNPROT
4 1 DPY UNPROT
5 1 DPY DEGRADED
6 1 DPY DEGRADED
7 1 DPY DEGRADED
8 1 DPY DEGRADED
9 1 DPY DEGRADED
10 1 DPY DEGRADED

DPY
The unit is part of a disk unit subsystem with device parity
protection.

DEGRADED
Indicates that a decrease in performance has occurred because a
component that is not critical has failed. No data is lost due
to this failure, but the damaged unit needs to be repaired or
replaced.

FAILED
Indicates that a unit has failed. If another unit fails, data
could be lost.

    For Cache batteries and stuff You might have to get into the 1. SST (Service tool menus) 2. START the SST 3. Key in 9 to work with resources containing Cache battery packs and then 5 to display information on the batteries life time and other info. Many Thanks Hari

    Try IBM's program for a quick, comprehensive report.
    CALL PGM(QSMBTTCC)

    You can put this in your job scheduler to run every month.  It is an easy way to keep an eye on IBM i batteries.

    Good note. To get the QSMBTCC utility, i5/OS V5R4, i OS 6.1 and i OS V7.1, can have PTFs SI40403, SI40404 and SI40406, respectively. For i 6.1 and 7.1, you can get the PTF in their later cume packages. -- Tom
