Specifying A Hot Spare; Auto Rebuild Of A Mirrored Array; Rebuilding A Redundant Array With A Hot Swap Drive - 3Ware 3W-6800 User Manual

Specifying a hot spare

Escalade Storage Switches give you the option to specify a hot
spare from one of your available drives. Hot spares should be
selected after mirror creation. Refer to Creating a disk array in the
3ware Disk Array Configuration Utility chapter. To specify a hot
spare after the system is booted, physically add the spare drive and
click on the check box next to the available port; then click on the
Add Spare button.
Note:
the drives used for the redundant array.

Auto rebuild of a mirrored array

If a hot spare is specified and the mirror degrades, an event notifica-
tion is generated and the hot spare dynamically replaces the failed
drive in a mirrored array without user intervention. Rebuild will
automatically be launched as background process and an event noti-
fication will notify the user when the rebuild process is complete.
Rebuilding a redundant array with a hot
swap drive
Hot swap allows a user to replace a failed drive in a redundant array
while the system remains up. Hot swap can be used when 24x7 sys-
tem operation is a consideration. If multiple drives are faulted in a
RAID 10 configuration, you must rebuild the drives sequentially by
port number starting with the lowest port number.
1 Click on the check box of the failed drive.
2 Click the Remove Drive button.
