Hello,    You are running older firmware.    I was going to suggest you clean the lost blocks, if you had a validated backup.  Just to be safe, during a quiet period you may want to reboot that array.   When it comes back online, reboot it again.  This will  completely restart both controllers.    Regards,  Don  #iworkfordell
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).
