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 is
generated. If the hot spare is of the same type (SAS or SATA) and of adequate
size, the hot spare automatically replaces the failed drive without user
intervention.
To specify a hot spare
1 In the list of Available Drives, highlight the drive to use.
2 Type s to specify that the selected drive will be the hot spare.
The words “Hot Spare” appear next to the drive in the Available Drives
list.

process.
