* [SCSI] mptfusion - fix panic in mptsas_slave_configureMoore, Eric2006-04-141-1/+9
| | | | | | | | | | | | | | | | Driver panic when RAID logical volume was present when driver loaded, or when a RAID logical volume was created on the fly. This issue was created in due to recent scsi_transport_sas change, when sas_read_port_mode_page was added into the mptsas drivers slave_config entry point. This new API expects that all sdev's to be assocated to an rphy, however that is not the case for logical volumes, as they are created using scsi_add_device, instead of sas_rphy_add().

* [SCSI] fusion - expander hotplug suport in mptsas moduleMoore, Eric2006-03-142-69/+289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for hot adding and removing expanders, and its associated attached devices. When there is a change in topology, the fusion firmware sends the MPI_EVENT_SAS_DISCOVERY event to the driver. The driver will read firmware config pages to determine what changes took place, and refresh drivers view of the world stored in ioc->sas_topology. Here is the details of the action the driver does: (1) Expander Added : The mptsas_discovery_work workqueue is called. Config pages read, and ioc->sas_topology is refreshed. The sas_phy_add() is called for each phy of the expander. The expanders attached devices are added via sas_rphy_add(). Added end devices are handled within the MPT_ADD_DEVICE logic in mptsas_hotplug_work workqueue. (2) Expander Delete : The sas_rphy_delete() will be called for the top most compenent of the parent that the expander is attached to. The sas_rphy_delete call will delete all the children phys, rphys, and end devices. This is handled from mptsas_discovery_work workqueue.

* [SCSI] mptspi: Add transport class Domain ValidationJames Bottomley2006-03-016-2459/+774
| | | | | | | | | | | | | | | | | This is the first half of a patch to add the generic domain validation to mptspi. It also creates a secondary "virtual" channel for raid component devices since these are now exported with no_uld_attach. What Eric and I would have really liked is to export all physical components on channel 0 and all raid components on channel 1. Unfortunately, this would result in device renumbering on platforms with mixed RAID/Physical devices which was considered unacceptable for userland stability reasons. Still to be done is to plug back the extra parameter setting and DV pieces on reset and hotplug. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
