7.5.5 Marking a Drive as Optimal
Use the Make Optimal option to change the status of a drive to optimal when you
want the controller to write information to it. For example, if you mark a drive
failed to remove it safely from the storage enclosure, you would then make it
optimal when you returned it to the storage enclosure.
Do not use Make Optimal to change the status of a drive which replaces a disk
drive that failed. Use the Rebuild option to properly replace a disk drive that
failed. Otherwise, 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 you detect corrupted files, you need to restore
data from backups.
To change the status of a drive to optimal, follow these steps:
1. Use the up and down arrow keys to highlight the Tools option from the main
menu; and press the Enter key. The utility displays the Tools menu, shown in
Figure 7–6.
2. Use the up and down arrow keys to highlight the Make Optimal option from
the Tools menu and press the Enter key. The cursor moves to the first drive
in the matrix available for you to make optimal, as shown in Figure 7–34.
