Checking And Resetting Battery Age On Sun StorEdge Arrays

Batteries on Sun StorEdge A1000, A3500 and T3 Storage arrays

When a battery has failed or when a battery has reached its “Life Span” and requires replacement as per the maintenance schedule, it is very important that you reset the “Battery Age”.

If you don’t reset the “Battery Age”, your system may continue to report battery issues and you may be replacing batteries as faulty, rather than batteries that have simply passed the expiry date.

Even worse you may be replacing batteries that may still be under manufacturers warranty simply because the system has not been reset.

To determine the “Battery age” use the following command:

raidutil -c c#t#d# -B (to check battery age)

For example:

subdisk#raidutil -c1t4d0 -B
LUNs found on c1t4d0
LUN 0 RAID 0 xxxxxMB
LUN 1 RAID 5 xxxxxMB
Battery age is between xxx days and xxx days.

Any battery that reports its age as over 730 days should be replaced as Preventative Maintenance.

Obviously this information is only accurate if a battery age reset was performed during the last time the battery was replaced.

To perform a battery age reset use the following command:

raidutil -c c#t#d# -R (Battery age reset)
