Alarms and Maintenance
When drive module locking switch (D) is transitioned from unlocked to locked, the LED will flash
red to indicate the drive is locked and in process of coming online (see
Locked).

5. When the LED turns off, log in as admusr and run the cpDiskCfg command to copy the partition
table from the good drive module to the new drive module.
$ sudo /usr/TKLC/plat/sbin/cpDiskCfg <source disk> <destination disk>
For example:
$ sudo /usr/TKLC/plat/sbin/cpDiskCfg /dev/sdb /dev/sda
6. After successfully copying the partition table, use the mdRepair command to replicate the data
from the good drive module to the new drive module.
$ sudo /usr/TKLC/plat/sbin/mdRepair
This step takes 45 to 90 minutes and runs in the background without impacting functionality.
7. Use the cat /proc/mdstat command to confirm whether RAID repairs are successful.
After the RAID is repaired successfully, output showing both drive modules is displayed:
Personalities : [raid1]
md2 : active raid1 sda2[0] sdb2[1]
26198016 blocks super 1.1 [2/2] [UU]
