A client has a 2800 server ( Adaptec 39160, PERC 4e/Di) has a failed RAID 5 due to controller. I was able to match a duplicate 2800 with the same configuration disks, OS, etc.
The RAID 5 array has three disks, of which only one shows online (the logical volume has failed), two drives would/will power up, but have "fallen out" of the array, when I arrived. My question is since the problem was due to the controller card, is it possible that the data has not been lost?
To make matters worse the tape backup unit had been not working. I had to order the client another tape unit, so I restore data, but older data and put this data set onto a NAS. The sequence of events was due to a lack of understanding that all data could be lost without a tape back up and regular drive maintenance. as well economics on the part of the client.The client was politely warned several times that data loss was quite possible if the drives went/fell out of the array..
Is it possible to move the drives to the working 2800 and recover the array with the working controller? Or is it that the data was lost even if the drives did not go bad, die etc?Orr will the disks have to be sent to one of the data rescue services given what has occurred?
In advance thanks for any help.
IF the drives are still somewhat healthy and the failure was firmware related, then it is very possible the data is undamaged. In which case, you can simply plug in the drives into another 2800/2850, boot to CTRL-M, Configure, View/Add, Disk View, and save on exit to import the configuration. For optimal results, firmware should be identical on the second 2800 OR newer.
If the drives are damaged/faulty and are not operational enough to rebuild/import/operate, then your only real option is data recovery services.
How did you determine the controller was reponsible for two drives going offline?
"CTRL-M, Configure, View/Add, Disk View, and save on exit to import the configuration"
There is no key or function called "Save" ... in View/Add, it should ask you which configuration you want to view: Disk or NVRAM; choose Disk. When you exit out of that screen, you will then be prompted to save it.
