Managing Disks in a C-series Platform

The SRC CLI provides commands to let you monitor disk status, replace faulty disks, and reinitialize disks in the system.

Replacing a Disk

If a disk in the C-series platform fails, you can replace it while the other disk remains active.

To replace a disk:

1.Disable the disk.

user@host> request disk disable device 0 1

2.Remove the disk from the system.

3.Insert a new disk.

4.Enable the disk.

user@host> request disk enable device 0 1

5.Initialize the new disk.

user@host> request disk initialize device 0 1

The command generates data on the disk that enables the disk controller to manage the disk. The disk controller copies data from the other disk and establishes mirroring between the two disks.

6.Verify that the disk is initialized. user@host> show disk status
