"defunct" disks but OS boots???
Posted on 2009-04-08
I inherited an IBM xSeries 350 server with Linux already installed and RAID 5 configured across three disks. I wanted to change to RAID 1 and have a hot-swappable disk, so I downloaded the latest ServeRAID CD and booted into it to reconfigure the array. Only, the ServeRAID said all three disks were "defunct" and therefore we couldnt make any changes. So I deleted the array altogether but then a scan for 'new' disks to add to a new array result in "no disks found." Strangely, if you reboot and remove the ServeRAID CD, the server boots back into Linux. A system/BIOS-level scan of the disks says there arent any hardware issues. So what am I missing? How do I get the ServeRAID to see the disks to create a new array?
