6.A.1.3 Stop DST
6.A.2 Disk Scrubbing
NOTES: For disk scrubbing 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.
This function enables the user to prevent unrecoverable data loss, recover bad blocks, and
fix parity errors.
Disk scrubbing provides the following advantages:
1. Disk scrubbing will not prevent normal host access. It will slow down the system's
overall performance however.
2. Disk scrubbing can be started and processed simultaneously for multiple arrays.
6.A.2.1 Overwrite Parity
Select either No (Default) or Yes. Select Yes to overwrite parity if inconsistency is detected
during disk scrubbing.
6.A.2.2 Scrub Mode
6.A.2.2.1 Manual Scrubbing
This function enables the user to select one array or all arrays to start disk scrubbing. This
function also enables the user to stop disk scrubbing at anytime.
