Goal

This document describes the procedure to reset the battery age on a Sun Storage A1000 or A3000 Array after its replacement.

Solution

This operation is performed using the raidutil command. Please execute the following steps in the order shown.

1. Identify the array controller names
   
   Log into the server as root and run the lad command. On a dual controller array, this will return two entries.
   
   Example:
   
   
   # /usr/lib/osa/bin/lad
   c1t5d0 1T80804402 LUNS: 0
     
   
   
   
   
2. Reset the battery age
   
   The raidutil command should be executed once on each controller. On a dual controller array, execute the command twice. On an A1000, there is only one controller.
   
   Example:
   
   
   # /usr/lib/osa/bin/raidutil -c c1t5d0 -R
   LUNs found on c1t5d0.
   LUN 0    RAID 5    51583 MB
   raidutil succeeded!
     
   
   
   
3. Ensure that the reset command worked
   
   Use the  -B option with the raidutil command.
   
   Example:
   
   
   # /usr/lib/osa/bin/raidutil -c c1t5d0 -B
   LUNs found on c1t5d0.
   LUN 0    RAID 5    51583 MB
   Battery age is between 0 days and 90 days.
   raidutil succeeded!
    
   
   
   
   
   On the serial port of RAID controller of a Sun StorEdge A1000/A3x00, we can check the detailed battery age using the printBatteryAge command.
   
   Example:
   
   -> printBatteryAge
   
   Current Time:          1125470837
   
    Battery Installation:  1075869851
   
    Battery Expiration:    1138077851
   
    Battery Warning:       1134449051
   
    Battery Age:  1 years  7 months  4 days
   
   103 Days until specified warning date. 145 Days until specified
   expiration date.
   
   value = 42 = 0x2a = '*'
   
   ->
   
   In the above example, the battery age is about 1 years 7
   months (= 1125470837 - 1075869851 = 49600986 seconds).
   
   The initial battery life span is 720 day s (= (1138077851 -
   1075869851) / 3600 / 24).
   
   Battery warning events (ASC/ASCQ=3FD9) start when battery age
   exceeds 678 days(= (1134449051 - 1075869851) / 3600 / 24).
   
   
   The spec of this initial battery-lifespan and Battery warning
   events start age, for A1000/A3x00 arrays, is the same since RAID
   Manager 6.1.1 at least.
   
   The approximate battery installation date, can be calculated
   using the adb command, as below. This time is based on the
   clock on the RAID controller.
   
   (Battery installation time is set when the battery age is
   reset.)
   
   Example:
   
   
      % echo 0t1075869851=Y | /usr/bin/adb
   
             2004 Feb  4 13:44:11
   
     %
   
   Current time on the RAID controller can be calculated using the
   same method.
   
   Example:
   
      % echo 0t1125470837=Y | /usr/bin/adb
   
             2005 Aug 31 15:47:17

   array, is described in document ID 78182.
