Specifying a hot spare
Escalade ATA RAID Controllers give you the option to specify a
hot spare from one of your available ports (currently shown as
offline). Hot spares should be selected after mirror or RAID 5 cre-
ation. Refer to
Creating a disk array in the 3ware Disk Array Con-
figuration 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 offline port; then click on the
Add Spare but-
ton.
Note: Hot spare drives must be equal to or larger than
the drives used for the redundant array.
Auto rebuild of a redundant array
If a hot spare is specified and the array degrades, an event notifica-
tion is generated and the hot spare dynamically replaces the failed
drive in a redundant 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 (if
3DM is running and e-mail notification is setup).
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, the drives are rebuilt sequentially starting
with the lowest port number.
