[SCSI] fc: add some more FC specific stats to fc_host

2012-07-20T07:31:47Z

The libfc provides more flexibility and with that we can monitor some more FC specific stats for FC exches or FCP error cases, this patch add such new FC stats. The patch adds *only* FC specific new stats to existing fc_host attribute container. Added stats names are self explanatory as existing FC stats already has, however anyway still added commentary along their definition to describe them.

[SCSI] scsi_transport_fc: Getting FC Port Speed in sync with FC-GS

2012-02-19T14:08:57Z

The values for the 4G and 10G speeds are not in sync with definitions in SM-HBA/FC-GS-x/etc. This patch brings them in sync to these specifications. The values are converted to strings when represented via sysfs attribute, hence that should cover for user space apps as they may not see any change.

[SCSI] scsi_transport_fc: Add FDMI host attributes

2012-02-19T14:08:57Z

This adds FC-GS Fabric Device Management Interface (FDMI) related attributes to fc_host_attr structure. This is in preparation for allowing FDMI attributes to be registered via libfc. Signed-off-by: Neerav Parikh Tested-by: Ross Brattain Acked-by: Robert Love Signed-off-by: James Bottomley

[SCSI] fc class: add fc host dev loss sysfs file

2010-10-07T22:09:44Z

This adds a fc host dev loss sysfs file. Instead of calling into the driver using the get_host_def_dev_loss_tmo callback, we allow drivers to init the dev loss like is done for other fc host params, and then the fc class will handle updating the value if the user writes to the new sysfs file.

[SCSI] fc class: add fc host default default dev loss setting

2010-09-05T16:45:23Z

This patch adds a fc_host setting to store the default dev_loss_tmo. It is used if the driver has a callack to get the value from the LLD. If the callback is not set, then we use the fc class module default value. Signed-off-by: Mike Christie Signed-off-by: James Bottomley

[SCSI] Allow FC LLD to fast-fail scsi eh by introducing new eh return

2010-04-11T14:49:33Z

If the scsi eh is running and then a FC LLD calls fc_remote_port_delete, the SCSI commands sent from the eh will fail. To prevent this, a FC LLD can call fc_block_scsi_eh from the eh callback, blocking the eh thread until the dev_loss_tmo fires or the remote port is available again. If (e.g. for a multipathing setup) the dev_loss_tmo is set to a very large value, thus preventing the scsi device removal , the scsi eh can block for a long time. For multipathing, the fast_io_fail_tmo is then set to a low value to detect path problems sooner. This patch introduces a new return code FAST_IO_FAIL. The function fc_block_scsi_eh now returns FAST_IO_FAIL when the fast_io_fail_tmo fires. This indicates that the LLD terminated all pending I/O requests and there are no more pending SCSI commands for the scsi eh to wait for. This return code can be passed back to the scsi eh to stop the escalation and finish the recovery process for this device. Signed-off-by: Christof Schmitt Signed-off-by: James Bottomley
