Monitoring and Managing BBU Units with the StorCLI Configuration Utility
The Storage Command Line Tool (StorCLI) is the command line management software designed for the MegaRAID
product line. The StorCLI is a command line interface that is designed to be easy to use, consistent, and easy to script.
NOTE
To increase the life of a battery, the battery is not fully charged. Band
Gap charging keeps the maximum battery charge within a band
comfortably above the data retention time requirement instead of
keeping the battery charged to the maximum level. However, when a
learn cycle is required, the battery is fully charged because a learn
cycle starts only once the battery is fully charged.
You can use the Storage Command Line Tool to monitor and manage BBU units. The StorCLI utility supports the
following battery backup unit (BBU) commands:
storcli /cx/bbu show
storcli /cx/bbu show all
storcli /cx/bbu set autolearnmode=
storcli /cx/bbu set bbuMode=
storcli /cx/bbu set learndelayinterval=
storcli /cx/bbu set powermode=sleep
storcli /cx/bbu set writeaceess=sealed
storcli /cx/bbu set learnStartTime=[DDD HH|off]
storcli /cx/bbu show modes
storcli /cx/bbu show properties
storcli /cx/bbu show status
storcli /cx/bbu start learn
storcli /cx/bbu start retentiontest
The detailed description for each command follows.
storcli /cx/bbu show
This command shows the summary information for the BBU unit that is used with a controller.
Input example:
storcli /c0/bbu show
storcli /cx/bbu show all
This command shows all the information of the BBU unit.
Input example:
storcli /c0/bbu show all
storcli /cx/bbu set autolearnmode=
This command starts the automatic learn cycle on the battery. The possible values are 0 - Enabled, 1- Disabled, and
2 - WarnViaEvent.
Input example:
storcli /c0/bbu set autolearnmode=0
storcli /cx/bbu set bbuMode=
