To Install A Raid System; Installing A Raid System - Nortel BCM200 Installation And Maintenance Manual

Installing a RAID system

Use this procedure to upgrade an existing standard BCM200 or BCM400 single disk configuration
to a RAID configuration.

To install a RAID system

1 Obtain the correct RAID field redundancy or upgrade components.
2 Shut down the system (see
3 Disconnect the BCM system from the AC power source.
4
Attach one end of the grounding strap to your wrist and the other end to a grounded metal
surface on the BCM main unit.
5
If applicable, remove the standard configuration hard disk cage from the BCM200 main unit
or BCM400 advanced function tray. Refer to
6 Remove the original programmed hard disk from the standard hard disk cage. Install and use
the original programmed hard disk as the primary disk in the RAID configuration (see
132). For further information on how to replace the hard disks, refer to
into a standard configuration hard disk cage" on page
Caution: Use only Nortel-approved replacement components. Contact your account
representative for the current list of approved replacement parts.
7 Install the RAID hard disk cage in your system. For further information, refer to
hard disk cage in a BCM200 main unit" on page 264
BCM400 main unit" on page
8 Install the main unit cover and access panel (if required).
9 Restore the BCM system to operation (see
234).
After bootup, the system automatically detects the presence of a RAID configuration and
begins the disk initialization and mirroring process. For further information on how to monitor
the disk mirror process, refer to
Note: RAID disk mirroring can take up to 3 hours to complete. The BCM system
continues to operate normally during the disk mirroring process. However, because disk
mirroring occupies computing resources, Nortel recommends that you perform disk
mirroring during a period of low call traffic.
Nortel recommends that you perform any system reboot only as required and at the
beginning of the disk mirroring process.
