e200i ld extension problem

[ASPhalt]

Hello All
I have BL460 server with e200i controller. Configuration:
=> ctrl all show config

Smart Array E200i in Slot 0 (Embedded) (sn: P694MP0878)

array A (SAS, Unused Space: 673855 MB)

logicaldrive 1 (136.7 GB, RAID 1, OK)

physicaldrive 1I:1:1 (port 1I:box 1:bay 1, SAS, 500 GB, OK)
physicaldrive 1I:1:2 (port 1I:box 1:bay 2, SAS, 500 GB, OK)

I want expand logical drive 1 to maximum size, but i have error:

=> ctrl slot=0 ld 1 modify size=max forced

Error: This operation is not supported with the current configuration. Use the
"show" command on devices to show additional details about the
configuration.

Somebody know what wrong in my configuration? I see e200 user guide, it support logical drive capacity extension. Thanks in advance

=> ctrl slot=0 ld 1 show

Online Capacity Expansion on the E200 controller requires the Battery-Backed Write Cache option to be installed.
So i need to get the "128MB Battery-Backed Write Cache" kit installed.
