Specifying a hot spare
The Escalade Storage Switch gives you the option to specify a hot
spare from one of your Available Drives. If a hot spare is specified
and the mirror degrades, an event notification will be generated.
The hot spare will dynamically replace the failed drive in a mir-
rored array without user intervention. Select a hot spare by navigat-
ing to an Available Drive. The Toggle Hot Spare verbiage at the
bottom of the screen will be black if the drive can be used as a hot
spare. Enter s to select the hot spare or to disable the hot spare if it
is already enabled.
Note:
Hot spare drives need to have the same or larger
storage capacity than the RAID 1, RAID 5 or RAID 10
drives.
Changing an existing configuration
1 Back up any disk arrays that contain data that you want to retain
before the configuration change.
2 Create new disk arrays following the instructions in the Deter-
mining your configuration, Creating a disk array and Delet-
ing a disk array sections. You may need to delete existing
arrays to free up disks first.
3 Boot, partition and format any new disk arrays or free disks.
4 When you are finished configuring, restore from backup any
data saved from previous disk arrays
Modifying a disk array
To modify an existing array you must first delete it then recreate it
with the new drives. As with all disk array operations, there is no
way to modify an existing array without overwriting data on the
drives involved.
