* [SCSI] hpsa: add driver for HP Smart Array controllers.Stephen M. Cameron2009-12-101-0/+10
| | | | | | | | | | | | | | This driver supports a subset of HP Smart Array Controllers. It is a SCSI alternative to the cciss driver.

* [SCSI] fnic: Add FIP support to the fnic driverJoe Eykholt2009-12-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Use libfcoe as a common FIP implementation with fcoe. FIP or non-FIP mode is fully automatic if the firmware supports and enables it. Even if FIP is not supported, this uses libfcoe for the non-FIP handling of FLOGI and its response. Use the new lport_set_port_id() notification to capture successful FLOGI responses and port_id resets. While transitioning between Ethernet and FC mode, all rx and tx FC frames are queued. In Ethernet mode, all frames are passed to the exchange manager to capture FLOGI responses. Change to set data_src_addr to the ctl_src_addr whenever it would have previously been zero because we're not logged in. This seems safer so we'll never send a frame with a 0 source MAC. This also eliminates a special case for sending FLOGI frames.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libFC is composed of 4 blocks supported by an exchange manager and a framing library. The upper 4 layers are fc_lport, fc_disc, fc_rport and fc_fcp. A LLD that uses libfc could choose to either use libfc's block, or using the transport template defined in libfc.h, override one or more blocks with its own implementation. The EM (Exchange Manager) manages exhcanges/sequences for all commands- ELS, CT and FCP. The framing library frames ELS and CT commands. The fc_lport block manages the library's representation of the host's FC enabled ports. The fc_disc block manages discovery of targets as well as handling changes that occur in the FC fabric (via. RSCN events). The fc_rport block manages the library's representation of other entities in the FC fabric. Currently the library uses this block for targets, its peer when in point-to-point mode and the directory server, but can be extended for other entities if needed. The fc_fcp block interacts with the scsi-ml and handles all I/O.

* [SCSI] scsi_dh: add infrastructure for SCSI Device HandlersChandra Seetharaman2008-06-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | Some of the storage devices (that can be accessed through multiple paths), do need some special handling for 1. Activating the passive path of the storage access. 2. Decode and handle the special sense codes returned by the devices. 3. Handle the I/Os being sent to the passive path, especially during the device probe time. when accessed through multiple paths. As of today this special device handling is done at the dm-multipath layer using dm-handlers. That works well for (1); for (2) to be handled at dm layer, scsi sense information need to be exported from SCSI to dm-layer, which is not very attractive; (3) cannot be done at all at the dm layer. Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

It also makes use of the enclosure services added in an earlier patch to display the enclosure topology in sysfs. At the moment, the enclosures are SAS specific, but if anyone actually has a non-SAS enclosure that follows the SES-2 standard, we can add that as well. On my Vitesse based system, the enclosures show up like this: sparkweed:~# ls -l /sys/class/enclosure/0\:0\:1\:0/ total 0 -r--r--r-- 1 root root 4096 2008-02-03 15:44 components lrwxrwxrwx 1 root root 0 2008-02-03 15:44 device -> ../../../devices/pci0000:01/0000:01:02.0/host0/port-0:0/expander-0:0/port-0:0:12/end_device-0:0:12/target0:0:1/0:0:1:0 drwxr-xr-x 2 root root 0 2008-02-03 15:44 SLOT 000 drwxr-xr-x 2 root root 0 2008-02-03 15:44 SLOT 001 drwxr-xr-x 2 root root 0 2008-02-03 15:44 SLOT 002 drwxr-xr-x 2 root root 0 2008-02-03 15:44 SLOT 003 drwxr-xr-x 2 root root 0 2008-02-03 15:44 SLOT 004 drwxr-xr-x 2 root root 0 2008-02-03 15:44 SLOT 005 lrwxrwxrwx 1 root root 0 2008-02-03 15:44 subsystem -> ../../enclosure --w------- 1 root root 4096 2008-02-03 15:44 uevent And the individual occupied slots like this: sparkweed:~# ls -l /sys/class/enclosure/0\:0\:1\:0/SLOT\ 001/ total 0 -rw-r--r-- 1 root root 4096 2008-02-03 15:45 active lrwxrwxrwx 1 root root 0 2008-02-03 15:45 device -> ../../../../devices/pci0000:01/0000:01:02.0/host0/port-0:0/expander-0:0/port-0:0:11/end_device-0:0:11/target0:0:0/0:0:0:0 -rw-r--r-- 1 root root 4096 2008-02-03 15:45 fault -rw-r--r-- 1 root root 4096 2008-02-03 15:45 locate -rw-r--r-- 1 root root 4096 2008-02-03 15:45 status lrwxrwxrwx 1 root root 0 2008-02-03 15:45 subsystem -> ../../../enclosure_component -r--r--r-- 1 root root 4096 2008-02-03 15:45 type --w------- 1 root root 4096 2008-02-03 15:45 uevent You can flash the various blinky lights by echoing to the fault and locate files. >From the device's point of view, you can see it has an enclosure like this: sparkweed:~# ls /sys/class/scsi_disk/0\:0\:0\:0/device/ block:sda generic queue_depth state bsg:0:0:0:0 iocounterbits queue_type subsystem bus iodone_cnt rescan timeout delete ioerr_cnt rev type device_blocked iorequest_cnt scsi_device:0:0:0:0 uevent driver modalias scsi_disk:0:0:0:0 vendor enclosure_component:SLOT 001 model scsi_generic:sg0 evt_media_change power scsi_level Note the enclosure_component:SLOT 001 which shows where in the enclosure this device fits. The astute will notice that I'm using SCSI VPD Inquiries to identify the devices. This, unfortunately, won't work for SATA devices unless we do some really nasty hacking about on the SAT because the only think that knows the SAS addresses for SATA devices is libsas, not libata where the SAT resides.

To avoid this pain I changed the driver to use only cached access to memory.
