cciss: decode unit attention in SCSI error handling code

2009-06-09T03:47:44+00:00

Make SCSI reset error handler decode unit attention ASC
and after a target reset wait for a unit attention that indicates
a reset occurred rather than just for any old unit attention.

cciss: simplify interface of sendcmd() and sendcmd_withirq()

2009-06-09T03:47:42+00:00

Simplify interfaces of sendcmd() and sendcmd_withirq() so that they
provide only one way to address commands instead of three ways.

cciss: Use schedule_timeout_uninterruptible in SCSI error handling code

2009-06-09T03:47:42+00:00

Use schedule_timeout_uninterruptible instead of schedule_timeout in the
scsi error handling code when waiting between TUR polls since we are not
interested in nor want to be interrupted by signals.

cciss: use schedule_timeout_interruptible()

2009-06-02T12:51:30+00:00

Use schedule_timeout_interruptible() instead of open-coding the set and
schedule parts.

cciss: fix SCSI device reset handler

2009-06-02T12:48:11+00:00

Fix the SCSI reset error handler to send a working, properly addressed
reset message to the target device and add code to wait for the target
device to become ready by polling it with Test Unit Ready.

The existing reset code was broken in that it didn't bother to set the
8-byte LUN address to anything besides zero, so the command was addressed
to the controller, which pretended to the driver that the command
succeeded, while doing nothing.  Ages ago I tested this code, but
unbeknownst to me, my test was flawed, and what I thought was a tape drive
getting reset was actually nothing of the sort.  Unfortunately, there is
still lots of Smartarray firmware that doesn't handle doing target resets
right, and this code won't help in those cases, but it also shouldn't make
things worse in those cases than they already are.

cciss: Fix cciss SCSI rescan code to better notice device changes

2008-10-09T06:56:18+00:00

Fix cciss SCSI rescan code to better notice device changes.
If you hot-unplug a tape drive, then hot-plug a different
tape drive into the same slot in a storage enclosure,
the cciss driver wouldn't notice anything had changed, as
it was only looking at the LUN address and device type.
Now it looks at the inquiry page 0x83 device identifier,
and vendor and model strings as well.

cciss: add support for multi lun tape devices

2008-08-06T10:30:04+00:00

This patch adds support for multi-lun devices in a SAS environment. It's
required for the support of media changers.

cciss: change the way we notify scsi midlayer of tape drives

2008-08-06T10:30:04+00:00

This patch changes way we notify the scsi layer that something has changed
on the SCSI tape side of the driver. The user can now just tell the driver
to rescan a particular controller rather than having to know the SCSI nexus
to echo into the SCSI mid-layer.
