RAID 5 Container #1 Dead, any hope for Data recovery?
Posted on 2004-10-21
Dear Experts Exchange -
Our school has a Dell PowerEdge 2500 which has major problems after a weekend power outage. Students and Faculty need data from this server, can you help?
Dell PowerEdge 2500
5 disk drives, RAID 5
2 containers: #0 4GB with OS, Windows 2000 Server and #1 131GB named H:\ for file storage
Perc 3 - adaptec
Monday am I arrived to the server in an off state.
Turned on and received "no boot device available", with 4 of 5 disks status lights slowly going from green to amber.
Called Dell, container information was OK, found both containers.
After scrubbing both containers was able to install a parallel OS and access data on H drive.
Tried to setup a backup to tape drive.
I arrived and server was in an on state with errors.
Three files were giving a corrupt or unreadable error message.
Since the backup didn't work, I started to copy data to other various locations on the network.
Received a message stating H:\ is not accessible the file or directory is corrupted and unreadable.
I thought I could let it continue to try to copy data off...
I arrived and the server could not be seen on the domain and was unresponsive, black screen.
Hard power off, back on and message " Array controller monitor failed ".
Several reboots, 50% of time will find array controller, 50% not.
Whe it does find the array controller drives that it sees are varied, sometimes drives 0,2,3 show up, other times drives 0,1,4...
Status is container #0 critical, container #1 critical
Called Dell, reseated drives, accepted configuration changes for the array controller, Dell ordering/shipping parts to rebuild the scsi chain.
Decided to update Bios and flash ESM. Container #0 OK, container #1 critical.
Boot up, array controller monitor OK, container #0 OK, container #1 critical. Able to access OS, try to access H:\ and recieve message "H:\is not accessible the file or directory is corrupted and unreadable" Now, in the continer configuration container #1 status is DEAD.
Still awaiting a technician to replace parts ordered by Dell.
If hardware replacement doesn't help, is there any hope of recovering data?
I've called a few data recovery companies, any suggestions?
thank you very much.
