access these devices too, as if the array controller were merely a SCSI
controller in the same way that we are allowing it to access SCSI tape drives.
SCSI error handling for tape drives and medium changers
-------------------------------------------------------
The linux SCSI mid layer provides an error handling protocol which
kicks into gear whenever a SCSI command fails to complete within a
certain amount of time (which can vary depending on the command).
The cciss driver participates in this protocol to some extent. The
normal protocol is a four step process. First the device is told
to abort the command. If that doesn't work, the device is reset.
If that doesn't work, the SCSI bus is reset. If that doesn't work
the host bus adapter is reset. Because the cciss driver is a block
driver as well as a SCSI driver and only the tape drives and medium
changers are presented to the SCSI mid layer, and unlike more
straightforward SCSI drivers, disk i/o continues through the block
side during the SCSI error recovery process, the cciss driver only
implements the first two of these actions, aborting the command, and
resetting the device. Additionally, most tape drives will not oblige
in aborting commands, and sometimes it appears they will not even
obey a reset coommand, though in most circumstances they will. In
the case that the command cannot be aborted and the device cannot be
reset, the device will be set offline.
In the event the error handling code is triggered and a tape drive is
successfully reset or the tardy command is successfully aborted, the
tape drive may still not allow i/o to continue until some command
is issued which positions the tape to a known position. Typically you
must rewind the tape (by issuing "mt -f /dev/st0 rewind" for example)
before i/o can proceed again to a tape drive which was reset.

Notes for the QLogic ISP1020 PCI SCSI Driver:
This driver works well in practice, but does not support disconnect/
reconnect, which makes using it with tape drives impractical.
It should work for most host adaptors with the ISP1020 chip. The
QLogic Corporation produces several PCI SCSI adapters which should
work:
* IQ-PCI
* IQ-PCI-10
* IQ-PCI-D
This driver may work with boards containing the ISP1020A or ISP1040A
chips, but that has not been tested.
This driver will NOT work with:
* ISA or VL Bus Qlogic cards (they use the 'qlogicfas' driver)
* PCI-basic (it uses the 'am53c974' driver)
Much thanks to QLogic's tech support for providing the latest ISP1020
firmware, and for taking the time to review my code.
