/cx/bbu show status
The /cx/bbu show status command shows the status of the BBU. Possible
values are as follows:
Testing. A battery test is currently in progress. This test can take up to 24
hours to complete. During the test, the BBU is not capable of backup
operation and the write cache might be disabled, deending on the unit’s
Storsave setting. If the test is completed without detection of a BBU error and
the BBU status changes to WeakBat or OK, the write cache is re-enabled. If a
Fault, Failed, or Error occurs during the test, the write cache remains in the
disabled state until you resolve the problem.
Charging. The BBU is currently charging the battery. The BBU automatically
starts charging whenever necessary. During charging, the BBU is not capable
of backup operation and the write cache might be disabled, depending on the
unit’s Storsave setting. After the test is completed successfully and the BBU
status changes to OK, the write cache is re-enabled. If a FAULT or ERROR
occurs during the test, the write cache remains in the disabled state until you
resolve the problem.
Fault. A battery fault is detected. The BBU is not capable of backup operation
and the write cache might be disabled, depending on the unit’s Storsave
setting. To re-enable write cache, replace the battery and/or the BBU board as
soon as possible.
Error. A BBU error is detected. The BBU is not capable of backup operation
and the write cache might be disabled, depending on the unit’s Storsave
setting. To re-enable write cache, replace the battery and/or the Battery
Backup Unit as soon as possible.
Failed. The battery failed a test. In this state, the BBU is not capable of
backup operation and the write cache is disabled. To re-enable write cache,
replace the battery and/or the BBU as soon as possible.
WeakBat. The BBU is functioning normally and is online and capable of
backing up the write cache. However, the battery is weak and needs to be
replaced.
OK. The BBU is ready, online, and capable of backing up the write cache. The
unit’s write cache is automatically reenabled, if applicable.
A dash (-) indicates that a battery or a BBU is not installed.
