Chapter 5: Configuration Parameters
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.
