I'm interested in migrating to a new (possibly non-HighPoint) card, and am wondering if I will be able to plug the OS drive into one channel on the new card and have it "just work." Is it a safe bet that it will? I'm curious to know if the array could be migrated just as easily, or if I should listen to my instinct and count on bumping into incompatibilities due to proprietary implementations. Here are the relevant dmesg lines of my system as it stands: hptrr: HPT RocketRAID controller driver v1.1 (Jun 7 2008 14:01:57) hptmv0: mem 0xf2000000-0xf207ffff irq 24 at device 1.0 on pci2 hptmv0: [GIANT-LOCKED] hptmv0: [ITHREAD] hptrr: no controller detected. da0 at hptmv0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-0 device da1 at hptmv0 bus 0 target 1 lun 0 da1: Fixed Direct Access SCSI-0 device -- Anthony Chavez http://hexadecagram.org/ mailto:acc@hexadecagram.org xmpp:acc@hexadecagram.org
