The S300 may not report drives correctly in OMSA and with a failed drive, OMSA may report them as all online, If the status of an array is degraded, you have a failed drive. Check the logs in OMSA to see if you have a entry for a failed drive. Otherwise, go into the controller bios, and check for the drive that is missing or look for the drive that says "online" but written in red, as that is the drive you need to replace.
Thanks to all who read this and any that reply. I have a T310 that the company I work for took over. The server is functioning but I noticed in open manage that the raid showed degraded and the amber light was blinking on the front of the case, I don't recall the pattern. The raid controller is a perc s300 with 3 500 gig hds in a raid 5. Open manage says the hard drives are fine. I didn't get an option to rebuild the raid. The only options I have are delete, assign/unassign and rename. I updated open manage from 7.2 to 7.4 and cleared the logs. The amber light went to solid blue but raid still shows degraded. The perc driver version is 2.0.0-0162 The bios version is 1.8.2 The service tag is [[[SVC TAG REMOVED BY MODERATOR]]] The OS is windows server 2008r2 Any advice would be appreciated. And when looking for the newest version of open manage there were several options. What would be the option for an iso of the disk we usually get in the box with a new server? Thanks
