48 Appendix B - Array Basics Appendix B - Array Basics The SCSI-IDE RAID Controller allows the set up and management of disk arrays. A disk array is a group of disks that appears to the system as a single virtual disk. This is accomplished through software contained in the RAID controller. RAID (Redundant Array of Independent Disks) refers to disk arrays in which part of the array storage capacity may be used to store redundant information.
Appendix B - Array Basics 49 A mirrored array is also highly reliable, because both disks in the pair must fail for the array to fail. For example, an array of five pairs can still maintain integrity even if five disks fail, as long as each pair is left with one good disk. The main disadvantage of a mirrored array is cost. Since all disks must have a twin, twice the number of disks must be used in the array capacity (an eight-disk array contains only four disks of usable capacity).
50 Appendix B - Array Basics Comparing RAID Levels Table B-1 illustrates the differences between the various RAID levels.
Appendix C - Troubleshooting 51 Appendix C - Troubleshooting StorCase Technical Support For assistance configuring and using this StorCase product, contact StorCase technical support at (888) 435-5460. Troubleshooting The RAID Controller is not properly identified by the SCSI adapter during initialization of the computer system. Cause - SCSI ID set for the RAID Controller could be the same ID used by another SCSI device attached to the same SCSI host adapter.
52 Appendix C - Troubleshooting Unable to access the RAID Controller after OS boots up. Cause - The RAID Controller might not be configured. Fix - Verify that the RAID Controller is configured for a RAID level. If no RAID level is configured, the OS will not detect the RAID Controller as a disk. Unable to access the Configuration Mode using the remote terminal (Monitor Utility). Cause - The terminal communication settings might not match the settings of the RAID Controller.
Appendix C - Troubleshooting 53 The front panel LCD displays alternating "Zz" characters. Cause - This occurs when the cache is full of write request data that has not been processed. The controller will halt requests from the host to flush out data in the cache. Fix - None required. The front panel LCD displays alternating "Ww" characters. Cause - This occurs when write requests in the cache are being processed. The controller will also halt requests from the host.
54 Appendix C - Troubleshooting Error Messages Error events alert the user of any failures associated with the controller, disk drives, or chassis. When an error event occurs, the problem should be corrected IMMEDIATELY. Table C-1 defines error messages and likely causes. Table C-1: Error Messages Error Message Description Number of disks found = y, needed = z Number of disks found (y) does not match the number of disks configured for. Number of disks (z) is required.
