StorageWorks RAID Array 200 Subsystem Family
Making a Drive Optimal
In some circumstances described in the Troubleshooting Your Subsystem section of
Chapter 6, you may have to use the Make Optimal option to change the state of a
drive from failed (FLD) to (OPT) optimal. If you use this method to change the state
of a drive instead of using the Rebuild option, the drive may contain faulty data.
_____________________CAUTION __________________________
When you use this option, ensure the integrity of the data stored on all
logical RAID drive(s) that use the failed drive. For example, do the
following:
•
For drives with a redundant RAID level (RAID 1, 0 + 1, or 5), use the
Parity Check option from the Tools menu.
•
Run an operating system file integrity check.
•
Run a data integrity check of your files (application-specific).
If corrupted files are detected, you have to restore data from backups.
To change the status of a drive to optimal, use these steps.
