Replacing Disk Drives

You can replace a failed drive in an array. For detailed instructions,
see Replacing a Failed Disk Drive in an Array on page 3-1.
Caution: You should not remove a disk drive that is used by
!
an array. This may cause you to lose data.

Blinking a Disk Drive

You can use the Blink function to blink the activity light of a
specific disk drive to help you visually identify it.
To blink a drive:
1 In the System Browser window, select the drive you want to
blink.
2 Click Blink.
Storage Manager Pro confirms that it will blink the disk drive for
approximately two minutes. You can stop the blinking by
clicking Unblink at any time.

Clearing Metadata from a Disk Drive

All of the member disk drives in an array contain metadata in the
first sectors of the disk drive. The controller uses the metadata to
identify array members after restarting or changing controllers.
You can clear the metadata from a disk drive if you have a drive
that was previously a member of an array. Disk drives in this state
display a message telling you to clear the metadata. After you clear
the metadata, you can use the disk drive in an array or as a spare.
