Disk Array Parameters 5-25

5.12 Disk Array Parameters

1. Rebuild Priority:

The Rebuild Priority determines how much of system resources

is consumed for rebuilding a degraded array. Higher priority

enables faster rebuild while leaving less resource for normal

I/Os.

2. Write Verify on Normal Access:

Errors may occur when a hard drive writes data. To avoid write

errors, the controller can force hard drives to verify written data.

There are three selectable methods:

 Verification on LD Initialization Writes

Performs Verify-after-Write when initializing a logical drive.

 Verification on LD Rebuild Writes

Performs Verify-after-Write during the rebuild process.

 Verification on LD Normal Drive Writes

Performs Verify-after-Write during normal I/Os.

Each method can be enabled or disabled individually. Hard

drives will perform Verify-after-Write according to the selected

method.
