BBU commands
The PERC Command Line Tool supports the following battery backup unit (BBU) commands:
perccli /cx/bbu set [learnDelayInterval=<val>|bbuMode=<val>|learnStartTime=[DDDHH|off]|
autolearnmode=<val>|powermode=sleep|writeaccess=sealed]
perccli /cx/bbu show
perccli /cx/bbu show all
perccli /cx/bbu show learn
perccli /cx/bbu show properties
perccli /cx/bbu show status
perccli /cx/bbu start learn
In the following, /cx specifies a controller where x is the controller index, and /bbu signifies a battery backup unit.
The detailed description for each command follows:
perccli /cx/bbu set <options>
This command sets bbu properties on the controller bbu.
Options:
● learnDelayInterval=<val>: number of hours to delay a learn cycle, not greater than 7 days
● bbuMode=<val>: val range 0–255
● autolearnmode=<val>: 0 — Enabled, 1 — Disabled, 2 — WarnViaEvent
