Differences in Rescan Between SCSI Adapters and Array Controllers There are differences in the way the Adaptec CI/O Management Software rescans SCSI adapters versus array controllers. This is due mainly to differences in complexity between an array controller and a SCSI adapter.

  • Page 100: Performing Array Operations

    Adaptec CI/O Management Software User’s Guide Adaptec CI/O Management Software allows you to perform a number of operations on arrays, spares, and stand-alone disks. Some of the operations are performed immediately; others can be scheduled for a later time, or scheduled to occur periodically at stated intervals (See Chapter 8, Scheduling and Monitoring Array Operations).
  • Page 101 Performing Array, Spare, and Disk Operations As long as the array member is physically functional, you can reconstruct it with the Reconstruct command. You can reconstruct the array immediately, or you can schedule the reconstruct to occur at a later time. Since the reconstruction process may take a long time, you may want to schedule it for a time when there is less activity on the system.
  • Page 102 Adaptec CI/O Management Software User’s Guide Note: When the spare is created, Adaptec CI/O Management Software should automatically start a Reconstruct operation on the array. If for some reason the reconstruct does not begin automatically, follow the remaining steps to perform it manually.

    Hard drives that support this technology continually analyze their performance and generate an alert if they determine that the disk is likely to fail in the next few hours. Adaptec CI/O Management Software generates an event notification if it receives this alert, allowing you to replace the disk before it actually fails.
  • Page 112 Adaptec CI/O Management Software User’s Guide Note: Pause I/O cannot assure the same level of protection from electrical noise that you have when you replace a disk in an enclosure that supports hot swapping. Every time you use this feature, you should only perform one action—either disconnecting a drive or inserting a drive, but not both.

    Adaptec CI/O Management Software User’s Guide Notes on Replacing Disk Drives We recommend that if you use hot swapping to replace a drive that supports tagged command queuing (TCQ), you replace it with a drive that also supports TCQ. Otherwise, a rescan may not detect that the drive has been swapped.
