Solving ServeRAID problems

For a complete description of how to diagnose ServeRAID problems see Chapter 18, “Solving ServeRAID problems” in the ServeRAID-4x Ultra160 SCSI Controller publication.

If you need help on your NAS 200, you should follow the support instructions as described in the Storage Unit Installation and User’s Guide GA27-4259appendix. Because the NAS 200 is a preconfigured system, do not use the information described in Chapter 19 of the ServeRAID-4x Ultra160 SCSI Controller publication.

Initial storage configuration of the NAS 200

The NAS 200 comes with preconfigured storage, formatted as follows:

vA RAID-level 1E array, for the System partition (drive letter will be C:)

vA RAID-level 1E array, for the Maintenance partition (drive letter will be D:)

vA RAID-level 5 array, comprised of the remaining storage. This array consists of a single LUN, for the Data drive (drive letter will be E). The size of this LUN depends on the number and size of hard disk drives that came with your NAS 200.

Attention: Note that although you will be using files in the System and Maintenance drives, it is strongly recommended that you do not repartition them. Doing so could wipe out important data and seriously impair the functioning of your system. Repartitioning is advised ONLY for the Data drive.

You can use the preconfigured Data drive, or delete it and configure new storage. If the preconfigured storage is agreeable with your requirements, you can proceed with “Chapter 5. Completing setup” on page 27. If you delete the Data drive, you will need to complete the steps in this chapter.

Creating arrays and logical drives

You configure RAID disk arrays and logical drives on your NAS 200 using the ServeRAID Manager. With ServeRAID Manager, you can configure and manage the storage mounted in the NAS 200 itself (the internal hard disk drives), in addition to the storage mounted in any IBM 5194 TotalStorage NAS 200 Storage Unit enclosures.

To start ServeRAID Manager, click the IBM NAS Admin icon, and then open the Storage folder and double-click ServeRAID Manager.

For details on how to use the ServeRAID Manager, see the following sections in Chapter 4, “Understanding RAID technology” in the ServeRAID-4x Ultra160 SCSI Controller publication:
