Retrieving hard disk drive information

The Disk Diagnostics page shows information about the Redundant Array of Independent Disks (RAID) hard-disk drive setup in a Message Storage Server (MSS). If a disk drive is replaced, this page also provides the rebuild command for an IDE RAID drive, and the rebuild status for either an MSS-S or MSS-H configuration.

The page displays different information depending on the configuration of the Message Storage Server (standard or high-availability):

• MSS-S: This page provides information about the two IDE RAID hard disks. See MSS-S IDE RAID system information, rebuild command, and rebuild status.
• MSS-H: This page shows the device and rebuild status of the SCSI RAID system. See MSS-H SCSI RAID system information and status.

To retrieve disk information about either configuration:

1. On the Disk Diagnostics page, click the Disk Information link.

The system displays the Disk Information page.

2. 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.
3. Click Display.

The system displays the Disk Information results page for that hard drive.

4. Click Return to Main

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 Disk Diagnostics page provides access to IDE RAID system information and device status for an MSS standard configuration (MSS-S). If you replaced an IDE RAID drive, this page provides the rebuild command and a query link for monitoring the disk rebuild status. For more information about using this page, see the online help.

To retrieve IDE RAID system information:

1. From the MSS Messaging Administration menu, select Diagnostics > Disk Information.
2. The RAID System Information section shows device status. Select one of the following links:
   • Query RAID System Information shows:
     • 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.

   • Rebuild RAID 1 Array is a command that starts the disk rebuild process. Use this command 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.
   • Query Rebuild Status shows if a disk drive recovery process is underway, and how much of the recovery has completed.

     Note: You can refresh this page periodically to monitor the progress of a disk rebuild. The entire operation should complete in less than 1 hour. After the rebuild begins, the Query RAID System Information page shows both disks as ONLINE.

3. Click Return to Main.

MSS-H SCSI RAID system information and status

The Disk Diagnostics page provides access to SCSI RAID system information and device status for the MSS high-availability configuration (MSS-H). This page includes information about the size and status (state) of the logical drive (RAID 5 array), physical devices (disk drives), and the SCSI RAID controller card.

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 retrieve SCSI RAID system information:

1. From the MSS Messaging Administration menu, select Diagnostics > Disk Information.

The system displays the Disk Diagnostics page.

2. The RAID System Information section provides access to RAID system information and disk drive rebuild status. To view this information, select one of the following links:
   • Query RAID System Information shows:
     • 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.
   • Query Rebuild Status shows if a disk drive recovery process is underway, and how much of the recovery has completed.

   Note: You can refresh this page periodically to monitor the progress of a disk rebuild. The entire operation takes at least 8 hours to complete, but could take much longer.

3. Click Return to Main.
