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 configuration.

The page differs depending on the configuration of the message server (standard or high-availability):

• MSS-S: This page provides information about the two IDE RAID hard disks. See MSS-S disk drive information, rebuild command, and 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.

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 drive on this machine.

MSS-S disk drive information, rebuild command, and status

The Disk Diagnostics page shows disk partition information and device status for an MSS standard configuration. If you replaced an IDE RAID drive, it provides the rebuild command and a query link for monitoring the disk's rebuild status. See the online help for details about using this page.

To retrieve IDE RAID system information:

1. Start at the Messaging Administration main menu and select:

Diagnostics
     Disk Information

The system displays the Disk Diagnostics page.

2. The RAID System Information section shows device status. Select the link in which you are interested:
   • Query RAID System Information shows:
     • the physical IDE disk devices installed (hda and hdc) and
     • whether the device is ONLINE (functional) or OFFLINE (failed)

     If a device is OFFLINE, write down the disk designation (hda or hdc), then see Replacing an IDE RAID drive.

   • Rebuild RAID 1 Array is a command that is used after you replace an IDE RAID drive. It begins the operation of copying the contents from the remaining original drive to the new one.
   • Query Rebuild Status shows if a disk drive recovery procedure is underway, and how much of it has completed.

     Note: You can refresh this page periodically to follow 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.

To retrieve partition information about either of the hard disks:

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

The system displays the Disk Information page.

2. Select the disk for which you want to view information from the drop-down menu.
3. Click Display.

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

4. Click Return to Main.

MSS-H SCSI RAID system information and status

The Disk Diagnostics page shows information about the MSS high-availability configuration hard disk drives and SCSI RAID controller card. See the online help for details about using this page.

To retrieve SCSI RAID system information:

1. Start at the Messaging Administration main menu and select:

Diagnostics
     Disk Information

The system displays the Disk Diagnostics page.

2. The RAID System Information section shows device status. Select the link in which you are interested:
   • Query RAID System Information shows:
     • the logical drives and whether or not the RAID 5 array is OPTIMAL (functional) or DEGRADED (a problem was detected).
     • the physical devices (disk drives). Status can be OPTIMAL (functional) or FAILED (faulty).

     Note: If one of the SCSI disk drives has been removed, this page simply fails to show the missing device.

     • the SCSI RAID controller card (always displays "Optimal" if the RAID 5 system is even partly functional).
   • Query Rebuild Status shows if a disk drive recovery procedure is underway, and how much of it has completed.

   RAID 5 status can be:

   • Optimal (fully functional)
   • Degraded (a problem was detected)
   • Reconstruct (the faulty disk drive was replaced, but the disk reconstruction is not complete).

   Device (disk drive) status can be:

   • Optimal (fully functional)
   • Failed drive (faulty disk). See Replacing a SCSI RAID drive.
   • Missing (the SCSI drive is pulled partly or completely out)
   • Replaced drive (the faulty disk drive was replaced, but the disk reconstruction is not complete).

   Note: You can refresh this page periodically to follow the progress of a disk rebuild. The entire operation takes up to 10 hours to complete.

3. Click Return to Main.
