Chapter 3. First-Time RAID Configuration Using 3BM
28 3ware Serial ATA RAID Controller User Guide
Specifying a Hot Spare
You can designate one of the Available Drives as a hot spare in 3BM. If a hot
spare is specified and a redundant unit degrades, an event notification will be
generated. The hot spare will automatically replace the failed drive without
user intervention.
To specify a hot spare
1 In the list of Available Drives, highlight the drive to use.
2Type s to specify that the selected drive will be the hot spare.
You’ll see the words “Hot Spare” appear next to the drive in the Available
Drives list.
Figure 17. Hot Spare Indicated
If a hot spare is already enabled, you can disable it by following the same
process.
Leaving Individual Drives as JBODs
By default, if you leave individual drives unconfigured (JBODs), they will not
be available to the operating system. If you want to be able to use individual
drives, configure them as single-disk units.
If you have JBODs attached to an 8000 controller that you want to use with
the 9000 controller, see “Moving Units from an 8000 Controller to a 9000
Controller” on page 126.
Note: In order to replace a failed drive in a degraded unit, a hot spare drive
must have the same or larger storage capacity than the failed drive.
