How to Replace a StorEdge A5x00 Disk Array

Use this procedure to replace a failed StorEdge A5x00 disk array. "Example--Replacing a StorEdge A5x00 Disk Array" shows you how to apply this procedure. This procedure assumes that you want to retain the disk drives.

If you want to replace your disk drives, see "How to Replace a StorEdge A5x00 Disk Drive".

1. If possible, back up the metadevices or volumes that reside in the disk array.

   For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

2. Perform volume management administration to remove the disk array from the configuration.

   For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

3. On all nodes connected to the disk array, run the luxadm remove command.

   # luxadm remove -F boxname

4. Disconnect the fiber optic cables from the disk array.

5. Power off, and disconnect the disk array from the AC power source.

   For more information, see the documentation that shipped with your disk array.

6. Connect the fiber optic cables to the new disk array.

7. Connect the new disk array to an AC power source.

   For more information, see the documentation that shipped with your disk array.

8. One at a time, move the disk drives from the old disk array to the same slot in the new disk array.

9. Power on the disk array.

10. Use the luxadm insert command to find the new disk array.

    Repeat this step for each node connected to the disk array.

    # luxadm insert

11. On all nodes connected to the new disk array, upload the new information to the DID driver.

    If a volume management daemon such as vold is running on your node, and you have a CD-ROM drive connected to the node, a device busy error might be returned even if no disk is in the drive. This error is an expected behavior.

    # scgdevs

12. Perform volume management administration to add the new disk array to the configuration.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.
