6.A.2.2.2 Schedule Scrubbing
NOTES: If the array is not at its optimum, the controller will cancel disk scrubbing and
record this event in the event log.
If the InfoStation is not ON at the time of a scheduled scrub, disk scrubbing will
not occur and controller will record this event in the event log.
This function enables the user to schedule disk scrubbing for one array or all arrays.
If enabled, the user can then select Once, Once per week, Once per 4 weeks, Once per
8 weeks, Once per 12 weeks, Once per 16 weeks, Once per 20 weeks, or Once per
24 weeks to schedule disk scrubbing.
6.A.2.2.3 View Schedule
This function enables the user to check the disk scrubbing schedule.
6.A.3 Disk Clone
NOTES: For disk cloning to start, the array must be at its optimum. There cannot be
any failed member disks or background tasks (such as adding a disk or ex-
panding an array).
Once disk scrubbing starts, the user cannot start any other background task
and array cannot be deleted.
Disk cloning, like mirroring, prevents failure of disks from data loss and unscheduled per-
formance degradation.
Disk cloning provides the following advantages:
1. Disk cloning will not prevent normal host access. It will slow down the system's
overall performance however.
2. Disk cloning can be started and processed simultaneously for multiple arrays.
6.A.3.1 Start Disk Clone
This function enables the user to start disk cloning.
