IBM xSeries 235 Xeon
Windows 2000 Server
6 x SCSI hdds
1 x DLT tape drive
Previously the server had 2 scsi hdds and an integrated Raid controller. Now it has a new raid controller in pci-x, 4 new scsi hdds and I haven't touched the integrated controller.
I have installed a new Adaptec Ultra320 SCSI raid controller in the pci-x slot in the server but can't seem to create more than one array.
I'm using the boot disc that came with the controller, which loads the linux gui serveRAID. I can see all the scsi hdds and the raid controller appears, as well as the old on-board controller.
The new controller shows all 6 hdds, and the old controller shows the tape drive.
Before serveRAID boots off CD, some raid information comes up saying the RAID status is invalid. But in serveRAID it shows the new controller so I assume it meant the old raid is now invalid.
When installing a RAID controller does the old controller need to be disabled? Is this migration and is it a dangerous procedure?
