Heres what I have:-
Server1 - DL360 G5
P400i embedded - firmware v7.22
Battery status = Failed
Server2 -Dl380 G5
P400 in slot 1 - firmware v5.26
Battery status = Failed
On Server1, in ACU, if I go into Array Accelerator Settings, I have the option to enable "Enable write cache when battery not present or not completely charged". If I enable this, then running controller slot-0 show from CLI will confirm the cache is now OK.
On Server 2, in ACU, there is no option. Listed as disabled in CLI. Also, I can run controller slot-1 modify nbwc=enable with no errors. But if I check using controller slot-0 show its still disabled?
So question is, is no battery valid on the P400i but not the P400?
Or is it because the firmware is old on the P400?
