Nortel Networks BCM200, 400 4.0 manual Replacing a RAID configuration hard disk

Chapter 22 Replacing the hard disk 257

Replacing a RAID configuration hard disk

Use this procedure to replace a faulty disk in an existing RAID configuration.

To replace a RAID configuration hard disk

1If you still have access to Element Manager, monitor the RAID hard disk activity status. Diagnose hard disk fault conditions and perform maintenance activities if required. For further information, refer to “RAID disk mirroring” on page 221.

2Determine if any of the RAID hard disks require replacement. If you determine a RAID disk is faulty, continue to step 3. If you determine no fault exists in the hard disks, you do not need to replace a hard disk.

3Shut down the system (see “Performing a system shutdown” on page 231).

4Disconnect the BCM system from the AC power source.

5Attach one end of the grounding strap to your wrist and the other end to a grounded metal surface on the BCM main unit.

6Remove the RAID hard disk cage from the main unit or advanced function tray. Refer to “Removing a hard disk cage” on page 258.

7Remove the faulty hard disk (primary or mirror). Refer to “Removing a primary hard disk from a RAID hard disk cage” on page 266 or “Removing a mirror hard disk from a RAID hard disk cage” on page 267.

8Install a new hard disk to replace the faulty hard disk. For further information, refer to “Replacing a hard disk in the hard disk cage” on page 265. Ensure the hard disk cables connect to the correct hard disk (see caution).

Caution: Use only Nortel-approved replacement components. Contact your account representative for the current list of approved replacement parts.

Caution: It is vital that you connect the correct IDE ribbon cables to the correct hard disks. Connect the primary IDE ribbon cable to the primary hard disk. Connect the mirror IDE ribbon cable to the mirror hard disk.

9Install the RAID hard disk cage in your system. For further information, refer to “Installing a hard disk cage in a BCM200 main unit” on page 262 or “Installing a hard disk cage in a BCM400 main unit” on page 263.

10Restore the BCM system to operation (see “Restarting the system after maintenance” on page 232).

After bootup, the system automatically detects the presence of a RAID configuration and begins the disk initialization and mirroring process.
