## `6120volverify` Test Options

The `6120volverify`(1M) test enables array administrators to execute manual parity checks on existing volumes. Parity checking applies only to RAID 1 and RAID 5 volumes. Check data parity using the 6120volverify test before performing tape backup overwrite cycles, approximately once every 30 days.

Before you run the 6120volverify test, you must first do the following:

- Run the Storage Automated Diagnostic Environment manually by following the procedures explained in "Running the ras_install Script."
- Generate a report for the device against which you are running the test (for example, Sun StorEdge 6120 arrays).

If the number of existing volumes do not match, an error message will be displayed.

Caution -

Ensure that system health is in optimal condition before running `6120volverify`. For example, make sure that no LUNs are under reconstruction, the status of all disks is zero, and other similar conditions are resolved before performing this procedure.
Refer to the Sun StorEdge 6120 array documentation, which are listed in Related Documentation of the Preface of this document, for more information.
