Milne" &lt;emilne&lt; at &gt;redhat.com&gt; This patch set adds changes to the SCSI mid-layer, sysfs and scsi_debug to provide enhanced support for Unit Attention conditions, as well as detection of a unit attention queue overflow condition and the ability for drivers to report sense data outside of normal command completion. There was some discussion about this a couple of years ago on the linux-scsi mailing list: http://marc.info/?l=linux-scsi&amp;m=129702506514742&amp;w=2 Although one approach is to send all SCSI sense data to a userspace daemon for processing, this patch set does not take that approach due to the difficulty in reliably delivering all of the data. An interesting UA condition might not be delivered due to a flood of media errors, for example. The mechanism used is to flag when certain UA ASC/ASCQ codes are received that report asynchronous changes to the storage device configuration. An appropriate uevent is then generated for the scsi_device or scsi_target object. An aggregation mechanism is </pre> Ewan D.

The 'lspci -nn' output reads as follows: I tried my own kernel (3.9.6) under gentoo with CONFIG_PATA_JMICRON and CONFIG_SATA_AHCI enabled. And I tried using the latest SystemrescueCD (with kernel 3.4.47) which has pretty much everything compiled into it. FreeBSD is recognizing the devices just fine. How do I get them to run on linux? - Matthias P.S. a side note: this is in an virtualized environment (VMWare ESXi) with pass-through. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo&lt; at &gt;vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html </pre> Matthias Prager 2013-06-19T13:12:51 http://comments.gmane.org/gmane.linux.scsi/82685 <pre>Content-Type: text/plain Content-Transfer-Encoding: 8bit Hello sir/madam how are you doing i hope fine.

The OS wouldn`t be accessible afterwards and require a hard reset. This driver patch has a fix for race condition between the doorbell and the circular buffer. The driver is modified to do an extra read after clearing the doorbell in case there had been a completion posted during the small timing window. With this fix, we ran IO stress for ~13 days. There were no IO failures.

I apologize if it's not a right place to ask questions. I use one LSI SAS 9207-8e controllers to attach 8 SSDs to my server. They together can deliver over 300,000 IO per second. I use mpt2sas driver and MPI-X is enabled. In order to handle so many IOs, I assign different IRQs to different CPU cores. I see very high CPU consumption, so I hope to enable interrupt coalescing to reduce CPU consumption. I monitored interrupts by using systemtap to count the number of invocations of handle_irq, and found the number of interrupts delivered by the LSI HBA is more or less the same as the number of IOs performed on the SSDs. I assume interrupt coalescing doesn't work in my case. If so, how do I enable interrupt coalescing in the LSI HBA. I checked all mpt2sas parameters and none of them are used to control it. The tool lsiutil doesn't work for this controller. I'm pretty sure the LSI HBA supports interrupt coalescing.

It supports the following adapters: - ExpressSAS R60F - ExpressSAS R680 - ExpressSAS R608 - ExpressSAS R644 This patch is split into ten parts to make reviewing easier. You'll need to apply all of them to get the complete patch. We have done some testing under x86 and x64 architectures, but the code is still under development and we expect to find additional issues.

However, commit 3eef6257de48ff84a5d98ca533685df8a3beaeb8 (Reduce error recovery time by reducing use of TURs) reduced the number of TURs by sending it only on the first failing command, which might or might not be a medium access command. So in combination this results in an erratic device offlining during EH; if the command where the TUR was sent upon happens to be a medium access command the device will be set offline, if not everything proceeds as normal. So instead of checking the EH command in the -&gt;eh_action callback we should rather call -&gt;eh_action when we're about to finish the command _and_ have sent a TUR previously. This should then set the device offline as advertised. Cc: Martin K.

Speed up failover by reducing the IB RC retry count and by notifying multipathd faster about transport layer failures by adding fast_io_fail_tmo and dev_loss_tmo parameters. - Make the SRP initiator better suited for use on NUMA systems by making the HCA completion vector configurable. Some of the patches in this patch series were posted previously as "Make ib_srp better suited for H.A. purposes". The changes compared to version five of that patch series are: - Left out patches that are already upstream. - Made it possible to set dev_loss_tmo to "off". This is useful in a setup using initiator side mirroring to avoid that new /dev/sd* names are reassigned after a failover or cable pull and reinsert. - Added kernel module parameters to ib_srp for configuring default values of the fast_io_fail_tmo and dev_loss_tmo parameters. - Added a patch fro</pre> Bart Van Assche 2013-06-12T13:17:53 http://comments.gmane.org/gmane.linux.scsi/82572 <pre> Fix a few issues that can be triggered by removing a SCSI device: - Fix a race between starved list processing and device removal that can trigger a kernel oops. - Avoid that a SCSI LLD callback can get invoked after scsi_remove_host() finished. - Speed up device removal by stopping error handling as soon as the SHOST_DEL or SHOST_DEL_RECOVERY state has been reached. - Save and restore the host_scribble field during error handling. Changes compared to v10: - Rebased and retested on top of Linux kernel v3.10-rc5. Changes compared to v9: - Changed one WARN_ON() statement into a WARN() statement. Changes compared to v8: - Addressed the feedback from Joe Lawrence - dropped the patch that makes scsi_remove_host() wait until the last sdev user is gone. - Eliminated Scsi_Host.tmf_in_progress since it duplicates state information available in Scsi_Host.eh_active. - Added a patch to avoid reenabling I/O after the transport layer became offline.
