I have been working on a patch to the driver to do just this, reset the
adapter during init if necessary. We want to limit the adapter's reset
as it takes time (an additional 45 seconds or longer) for the Firmware
to cycle... I will bump the priority of the testing for this patch.
Sincerely --
Hello List,
Running vanilla kernel 2.6.20.4 (unmodified from kernel.org) on an IBM x335
Server with LSI Logic 53c1030 and two SCSI disks in RAID-1, we have some
serious performance issues that we suspect are present due to driver
problems.
The performance is as follows:

Fixed the kernel-doc comment for ibmvscsi_slave_configure. Thanks to
Randy Dunlap for catching that.
Adding a slave_configure function for the driver. Now the disks can be
restarted by the scsi mid-layer when the are disconnected and reconnected.

fyi...
For FC, we have several async events, and allow for LLDDs to send their own
data or augment the generic transport event w/ additional LLDD-data. The
infrastructure is implemented generically within the scsi midlayer.
We are using Netlink w/ broadcasts to deliver the events rather than

Fair enough, though I definitely lean towards some use of sysfs / device
model for AN-style events specifically. The media change events are
generated by the device, not the transport, and we should definitely
have an object in the device model that represents the device

Remove the auto RAID 0 array creation module parameter, since
support for this function has been removed from the firmware.

Some ipr adapters may take longer than others to come operational.
This patch makes this timeout different for different adapters,
while still preserving the module parameter which can be used
to globally override the default.

The ipr driver has a sysfs attribute which can be used to
adjust the logging level of the driver for error events.
The error response data for commands can be dumped by
increasing the logging level of the ipr driver. This
currently only works for JBOD passthrough devices.
This patch enables this
This patch fixes a problem discovered on a system with some
bad SATA devices attached. If a command to a SATAPI device
times out and the device gets reset as part of error recovery,
its possible that ipr will set err_mask to indicate a device
error has occurred. If this happens, a request sense
For ipr SAS adapters that support dual pathing, this
patch modifies ipr to log an error when a path fails.

Improve overall command performance by embedding the scatterlist
in the command block used by the adapter. This decreases
