Recover RAID5+SA5300
Posted: Mon Apr 06, 2009 12:36 pm
I wonder if R-Studio can help in my situation.
Epilogue:
I have a Compaq Proliant ML370 server w/Compaq SA5300 SCSI Raid controller.
All six disk slots are ocupied w/72GB disks and they are configured as RAID5 no spare.
This RAID5 disk has only one volume and Windows 2003 Operating system. The system had no errors.
There was a need to save data from the system disk to an external storage.
For this purpose I used a cage I removed from a dicommissioned HP DL380G1 server.
Put four 150GB disks in and connected the external cage to the second channel at SA5300 and powered up the system.
At the prompt, I pressed F8 and got to the RAID controller utility and configured a 2nd RAID5 of all 4 disks.
Everything was working as expected.
Problem:
Then I tried to simulate the external cage removal.
I shut down the server and disconncted the external cage.
Turned on the server and pressed F8 to get to the controller Utility.
Then I deleted disk 2 and tried to Save the configuration.
This task normally takes less than a minute.
In my case it froze.!!!.
After I waited a while I restarted the server but NOW my system disk did not show up.
Controller reported "No logical disk present". The config. utility did nor show any configured RAIDs.
But I can see six idle disks with OK status.
Thus I lost my main disk.
Here's the question: Can I recover my data from lost RAID5?
If yes, can the R-studio sw help and how I can do this?
Can I just configure a new RAID with the same disk and try to recover lost partition?
Or ALL my data lost?
Please help.
Thank you.
