the hard disk is apparently running on a CCISS HP SmartArray raid
controller of some sort, and is being seen as /dev/cciss/c0d0 . I'm
not sure these support tape. Now, if this is the sort of SmartArray
raid controller which takes over and manages the other SCSI channels,
maybe you have to go into the BIOS (or the SmartArray BIOS) and disable
this.
pertinent info from DMESG... I note the 53C1030 is seen as PCI device
02:03 and the CCISS is 0A:04

note those first two are two PCI Functions on the same PCI Slot
(actually, I believe that may be an onboard device), while the 2nd two
are two seperate SmartArray 6400 cards. I bet you plugged your tape
into a SmartArray port rather than a onboard(?) SCSI port. The PCI
addressing notation there like 02:03.0 is Bus:Slot.Function
