Chapter 6: StorCLI
Working with the Storage Command Line Tool
Table 53 BBU Mode
Input example:
storcli /c0/bbu set bbuMode=2
NOTE BBU modes are supported on any iBBU08/09 bbu/controller combo
and later-generation controllers.
storcli /c
x/bbu set learndelayinterval=<value>
This command sets the learn delay interval for the BBU in hours. The value must be between 0 to 168 hours (7 days).
Input example:
storcli /c0/bbu set learnDelayInterval=30
storcli /c
x/bbu set powermode=sleep
This command places the battery in low-power storage mode. The battery automatically exits this state after
5 seconds.
Input example:
storcli /c0/bbu set powermode=sleep
storcli /c
x/bbu set writeaccess=sealed
This command seals the gas gauge EEPROM write access.
NOTE Use the set writeaccess=sealed command at manufacturing
time.
Input example:
storcli /c0/bbu set writeaccess=sealed
storcli /c
x/bbu set writeaccess=sealed
This command seals the gas gauge EEPROM write access.
NOTE Use the set writeaccess=sealed command at manufacturing
time.
Input example:
storcli /c0/bbu set writeaccess=sealed
