Server showing parity as red

Hello All,

i seen that my HDD light was on solid so i logged into the server and i see that the parity is red with no options to rebuild, clean or test. I had a few power outages  the other day and assume that started this issue. When i log into unraid, i see the following;

STARTED, 5 disks in array.    PARITY NOT VALID: DISK_DSBL

looks like the issue started at 22:43 on July 5th
