The device is still working. I replaced a failed drive and I now see the message: The RAID set lost blocks

It is not saying a volume lost blocks but the raid set (RAID 50). 24 10K SAS drives.

I acknowledged the error and do not know what to do next. Is there a way to validate the array? Maybe another drive is going bad (have 2 hot spares and 2 more cold spares).

Any help is appreciated!
