The RAID System Information page shows information about the Redundant
Array of Independent Disks (RAID) hard-disk drive setup in a Message
Storage Server (MSS). This page displays different information depending on the configuration
of the Message Storage Server (standard or high-availability):
To retrieve disk information about either configuration:
- On the Disk Information page, from the drop-down menu, select the disk for which you want
to view information. For the MSS-H configuration, you can select
only the logical drive.
- Click Display.
The system displays the Disk Information results page for that
hard drive.
Note: Information about the IDE drive in the Message
Application Server does not appear on this page. Use
standard Microsoft Windows techniques to view information
about the hard disk drive in an MAS.
MSS-S IDE RAID system information, rebuild command,
and rebuild status
The RAID System Information page shows the following IDE RAID system information
and device status for an MSS standard configuration (MSS-S):
- The physical IDE disk devices installed (hda and hdc),
and
- Whether an installed device is ONLINE (functional)
or OFFLINE (failed).
If a device is OFFLINE, write down the disk designation
(hda or hdc). You might need to replace the hard drive.
For repair information, see Performing
hardware maintenance. For an S3400-family server,
see Replacing an IDE RAID drive.
To rebuild an IDE RAID array, from the MSS Messaging Administration menu, in the Server Information category, select Rebuild RAID 1 Array.
Note: Use the Rebuilt RAID 1 Array page to rebuild the RAID 1 array only if the rebuild process does not start automatically after you replace an IDE RAID drive and reboot the server. The rebuild process copies the contents from the remaining original drive to the new drive.
To query the RAID 1 array rebuild status, from the MSS Messaging Administration menu, in the Server Information category, select Rebuild RAID Status.
The RAID Rebuild Status page shows if a disk drive recovery process
is underway, and how much of the recovery has completed. Use this page
to monitor the progress of a disk rebuild. The rebuild
operation should complete in about 1 hour, but may take longer. After
the rebuild begins, the RAID System Information page shows both disks as ONLINE.
MSS-H SCSI RAID system information and status
The RAID System Information page shows SCSI RAID system information
and device status for the MSS high-availability configuration (MSS-H).
This page shows the following information about the size and status (state)
of the logical drive (RAID 5 array), physical devices (disk drives),
and the SCSI RAID controller card:
- Logical drive name and path, state, number of blocks, drive size in Megabytes (MB), and block size in bytes.
- Physical device state, number of blocks, drive size in Megabytes (MB), and block size in bytes.
Note: If one of the SCSI disk drives was removed, this page does not show the missing device.
- SCSI RAID controller card information, including the serial number and status. The status is always displays Optimal if the RAID 5 system is even partly functional.
The logical drive state can be:
- Optimal - fully functional
- Degraded - a problem was detected
- Reconstruct - a faulty disk drive was replaced,
but the disk reconstruction is not complete
The physical device states can be:
- Optimal - fully functional
- Failed drive - faulty disk. For repair information,
see Performing hardware maintenance.
For an S3400-family server, see Replacing
a SCSI RAID drive.
- Missing - the SCSI drive is pulled out
- Replaced drive - a faulty disk drive was replaced,
but the disk reconstruction is not complete
To rebuild an SCSI RAID 5 array, from the MSS Messaging Administration menu, in the Utilities category, select Rebuild RAID 5 Array.
Note: Use the Rebuilt RAID 5 Array page to rebuild the RAID 5 array only if the rebuild process does not start automatically after you replace a disk drive.
To query the RAID 5 array rebuild status, from the MSS Messaging Administration menu, in the Server Information category, select Rebuild RAID Status.
The RAID Rebuild Status page shows if a disk drive recovery process is underway, and how much of the recovery has completed. Use this page to monitor the progress of a disk rebuild. The rebuild operation takes at least 8 hours to complete, but could
take much longer.
