3.7.5 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 state must be Normal in order to perform Check Vol-
ume Set. Only RAID levels 3, 5, and 6 supports this function.
To perform Check Volume Set function:
1. Click on the Check Volume Set link.
2. Tick 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
