I was contacted by a client about this system that they're having trouble with.
As the system boots, I can hit ALT + 3 to enter the 3ware bios and it shows the drives are available in an exportable unit.
Once the system boots up into CentOS, it does not see the 3ware controller on /dev/sdb where it had formerly appeared.
lspci shows a 3ware controller of unknown type.
'fdisk -l' does not show anything on /dev/sdb
No one has done anything with the hardware or software of this system, it's just been sitting running for 5 or 6 years in the customer's office until one day they could no longer access their content on the raid.
From the symptoms I gather the drivers got lost or corrupt or maybe the controller has gone bad in some minor way?
I wonder how I can troubleshoot or what is the best way forward to get their data back?
Should I move the raid to a new system or is there a way to get the 3ware drivers back into the kernel, or has something else gone wrong?
