Sun StorEdge T3 and T3+ Array Field Service Manual • September 2001

5.1.3

Checking Data Parity

Caution –

It can take up to several hours for the parity check once the

vol verify

command is executed. Execution of this command might affect system performance,
depending on system activity and the verification rate selected.

●

Use the

vol verify

command to perform a parity check of the drives.

You can also use the

fix

and

rate

options:

Where:

■

fix

recalculates and rewrites the parity block if a mismatch is detected.

■

rate specifies the speed with 1= slowest and 8 = fastest.

Note –

The

vol

command is not re-entrant. Other

vol

commands cannot run on the

array or partner group until the

vol verify

operation has completed.

Note –

It is a good practice to run

vol verify

before recycling backup tapes to be

sure the image is correct before over-writing previous images.
