Compaq Infortrend manual Verification on Writes, 9-28

Verification on Writes

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

Move cursor bar to the desired item, then press [ENTER].

Choose Yes in the confirm box to enable or disable the function. Follow the same procedure to enable or disable each method.

IMPORTANT!

•The “verification on Normal Drive Writes” method will affect the “write” performance during normal use.
