Had a few backup errors over the weekend that were related to disk issues. Troubleshooting this lead to finding the disk appearing with the yellow exclamation mark which is a warning. The disk showd up in "failing" state.

Checked HP system logs

checked the MSA itself

checked OS logs

everything checked out green and not hardware issues.

SOLUTION:

Went into VEA, Right click on the failing disk > “reactivate disk”

Note: I did this to clear out the flag since there really were no hardware issues. The warning may have been because of a glitch in disk communication.
