Error StorageTek 2540 battery failed

Hi all,

My Sun StorageTek 2540 have redundant batteries, but a battery was failed.

Code:
# /opt/SUNWstkcam/bin/sscs list -d MyStorage1 fru
Name                       FRU         Alarm    State               Status Revision    Unique Id
-------------------------- ----------- -------- ------------------- ------ ----------- ----------------------------
Tray.85.Battery.A          Battery     -        Enabled             OK     N/A         SY81500764SA
Tray.85.Battery.B          Battery     Critical Enabled but Offline Error  N/A         SY81500830SA

After the battery failure, the server read/write performance was down (I assume)!

I read some doc from internet and I found a reason to performance down when storage array battery failed. A guy tell me you should change "Write Cache without Batteries" option to ENABLE on the storage volume using SSCS CLI utility.

Command is below:
/opt/SUNWstkcam/bin/sscs modify -a MyStorage -p disk_pool -b enable

I afraid that lost any data on the storage box after execute above command.

Please tell me what happening when I execute " /opt/SUNWstkcam/bin/sscs modify -a MyStorage -p disk_pool -b enable" command on the storage box?

BR,
Buyantugs
