DL100 Storage Server 1TB: RAID5 data volume inaccessible
When checking in Adaptec storage manager, we found that port0 failed (see photos) while disk LEDs were all in a normal state (no amber, no red). At this moment, access to RAID5 was normal (slow disk access which is normal) and a backup has been performed by the customer. Since the server was under warranty and a replacement SATA disk (250GB) was not available in our stock, even in HP was also unavailable (!!), we have performed a rescan on the controller and the disk returned to optimal state with a warning state of rebuilding. After that, the data volume is no more accessible (unknown state). Also, after restarting the server and doing ctrl-A then checking the data volume (RAID5) properties, disk0 and disk3 states in that volume were off while disk1-2 were on. If checking both RAID1 status of C and D, all disks were on. Opening the server cover to check for cables problem (as per HP service note) the disk-3 sata connector was loosen from one side of the connector (remember that port0 was showing the problem in Adaptec manager !!) while other ports were seated correctly, Eventhough, all connectors have been removed-reinserted and the tie cutted, RAID5 deleted - recreated. My problem is: the customer is not convinced by the connectors issue that might caused the data loss and needs an HP explanation.
