5.3.5 Check Volume Set
Use this function to perform Volume Set consistency check, which verifies the correctness of
redundant data (data blocks and parity blocks) in a Volume Set. This basically means computing the
parity from the data blocks and comparing the results to the contents of the parity blocks, or
computing the data from the parity blocks and comparing the results to the contents of the data
blocks.
NOTE: The Volume Set must be in a Normal state in order to perform the Check
Volume Set. Only RAID levels with parity (redundant data) such as RAID Levels 3,
5, 6, 30, 50 and 60 support this function.
To perform Check Volume Set function:
1. Click on the
Check Volume Set
link.
2. Click on from the list the Volume Set you want to check. Select the Check Volume Set
options.
Check Volume Set Options:
•
Scrub Bad Block If Bad Block Found, Assume Parity Data is Good
•
Re-compute Parity if Parity Error, Assume Data is Good
NOTE: When the 2 options are not selected, it will only check for errors. It
is recommended to perform Check Volume Set with the 2 options
unselected at first. If the result shows error, the two options can be
selected and redo Check Volume Set to correct the errors.
