Accessing the RAID status report using Element Manager

Use the procedure in this section to display a status report that summarizes primary master and mirror master hard disk installation and operational information. The status report is valid only for systems equipped with a RAID configuration.

Note: You must ensure the system status monitor service is enabled to monitor primary master and mirror master disk operation and disk mirroring activity.

To access the RAID status report

1Open Element Manager.

2From the Administration tab, click System Status, and then click Disk Mirroring.

The Disk Mirroring screen displays, which displays the hard disk operational status information.

3Confirm that the primary master and mirror master hard disks are functional (see Table 82).

Monitoring disk mirroring using Element Manager

Use this procedure to verify and monitor the disk mirroring process. Disk mirroring is the process of duplicating the data from one hard disk to the other. After RAID installation and system bootup, the system automatically detects the presence of a RAID configuration and begins the disk initialization and mirroring process. This procedure is valid only for those systems equipped with a RAID configuration.
