/cx/bbu show attribute [attribute ...]
This command shows the current setting of the given attribute(s) on the BBU board. One or many attributes can be specified. Specifying an invalid attribute will terminate the loop. Possible attributes are: batinst, bootloader, cap, fw, lasttest, pcb, ready, status, serial, temp, volt.
/cx/bbu show batinst
This command shows the date when the current battery was installed.
/cx/bbu show bootloader
This command shows the BBU's boot loader version.
/cx/bbu show cap
This command shows the battery capacity in hours.
A value of '0 hours' will be displayed if the battery capacity test has never been run.
 
Note: The estimated BBU capacity hours displayed is based on the measurement taken during the last test. If you have not run the BBU test command for some time, this number can be misleading. You can use the command /cx/bbu show lasttest to check the date of the last test. For information about running a test, see /cx/bbu test [quiet].
/cx/bbu show fw
This command shows the BBU firmware version number.
/cx/bbu show lasttest
This command shows the date the battery capacity was last measured. If the battery capacity test has never been run, then 'xx-xxx-xxxx' will be displayed.
 
Note: The estimated BBU capacity hours displayed is based on the measurement taken during the last test. If you have not run the BBU test command for some time, this number can be misleading. For information about running a test, see /cx/bbu test [quiet].
/cx/bbu show pcb
This command shows the PCB revision number on the BBU.
/cx/bbu show serial
This command shows the BBU serial number.
/cx/bbu show status
This command shows the status of the BBU. Possible values are:
Testing. A battery test is currently in progress. This test may take up to 24 hours to complete. During the test, the BBU is not capable of backup operation and the write cache of the RAID controller is also disabled. If the test is completed with no error and the BBU status changes to WeakBat or OK, the write cache will be re-enabled. If a Fault, Failed or Error occurs during the test, the write cache remains in the disabled state until the problem is fixed.
Charging. The BBU is currently charging the battery. Charging is started automatically by the BBU whenever necessary. During charging, the BBU is not capable of backup operation and the write cache is disabled. Once the test is completed with no error and the BBU status changes to OK, the write cache will be re-enabled. If a FAULT or ERROR occurs during the test, the write cache remains in the disabled state until the problem is fixed.
Fault. A battery fault is detected. The BBU is not capable of backup operation and the write cache is disabled. Replace the battery and/or the BBU board as soon as possible so that the write cache will be enabled again.
Error. A BBU error is detected. The BBU is not capable of backup operation and the write cache is disabled. Replace the battery and/or the Battery Backup Unit as soon as possible so that the write cache will be enabled again.
Failed. The battery failed a test. In this state, the BBU is not capable of backup operation and the write cache is disabled. We recommend you replace the battery and/or the Battery Backup Unit as soon as possible so that the write cache will be enabled again.
WeakBat. The BBU is functioning normally and is online and capable of backing up the write cache. However, the battery is weak and should be replaced.
OK. The BBU is ready, online and capable of backing up the write cache.
- (dash) A battery is not present or a Battery Backup Unit is not installed
/cx/bbu show temp
This command shows the temperature status of the battery. The status can be OK, HIGH, LOW, TOO-HIGH, and TOO-LOW. The HIGH and LOW are in warning range. TOO-HIGH and TOO-LOW are out of the operating range and indicate that it may be time to replace the battery. (Contact AMCC to obtain a replacement battery.)
/cx/bbu show volt
This command shows the voltage status of the battery. The status can be OK, HIGH, LOW, TOO-HIGH, and TOO-LOW. The HIGH and LOW are in warning range. TOO-HIGH and TOO-LOW are out of the operating range and indicate that it is time to replace the battery. (Contact AMCC to obtain a replacement battery.)
