We have a real emergency here and want to ask the experts.
We picked up a client that had a dell Vostro box running windows 2003 server. It contained 4 sata drives running off the onboard controller. Each drive had various data. They wanted to improve performance, So I recommended we install an adaptec 3405 raid controller in RAID 10 config. We initialize all 4 drives and gain performance with the RAID 10 after restoring the data of course.
At the same time we upgraded them to 2008 Server.
Everything went perfect.... then suddenly the controller alarm sounded.
Adaptec storage manager indicates drive 2 had failed. I thought this was strange ...however I figured perhaps that drive was already on its way out.
Keep in mind the server was running perfectly...we even had the staff into their software and databases for a few hrs working away while we went out to get a replacement drive to rebuild the raid.
Then we went to swap the drive - the server took about 15mins to shutdown....swap the drive...and on reboot 2008 server runs a CHKDSK!!!!!! recovering orphaned files etc....I was not happy to see this. Finally got into the server and SM....drive 2 was rebuilding.... However the data was totally inconsistent!!
The database they use was corrupted.... we were getting MS jetdatabase errors - 2 users trying to change file same time ....all indicative of bad data.
ANother reboot to see
This time alarm again!!!! channel 2 is missing all togther ! The card is only showing 3 channels and devices!
Do I have a bad card? Bad firmware?
Where to start?
