Battery replacement on Sun StorEdge A1000 array

Updated 03 Sep 2011 | 1 minute read | 2240 views | Storage

A simple post providing the steps necessary to health check and if necessary replace the batteries in a Sun StorEdge™ A1000 array.

Firstly, use the healthck command to perform a health check on the raid modules to see if any of the batteries need replacing:
```
root@solaris# healthck -a
tstary1:            Battery Alert 
tstary2:            Battery Alert
healthck succeeded!
```
From the above output we see a "Battery Alert" is listed against both array devices.
List the array devices:
```
root@solaris# lad
c1t3d0 1T07616314 LUNS: 0 
c2t3d0 1T22096148 LUNS: 0
```
From the about output, our devices are listed as c1t3d0 and c2t3d0
Use the raidutil to get the battery age. For example:
```
root@solaris# raidutil -c c1t3d0 -B
LUNs found on c1t3d0.
LUN 0    RAID 5    346928 MB
Battery age is between 630 days and 720 days.
```
From the about output, we can see that the battery age is greater than the 2 year shelf life, and therefore need replacing.
To perform the battery replacement, follow the following 5 steps:
Turn OFF the power for the A1000

Push down the catch on the battery

Pull the battery out

Slide the new battery into the battery port

Turn ON the power for the A1000
Finally, reset battery state to zero. For example:
```
root@solaris# raidutil -c c1t3d0 -R
```
