The smartpqi driver -is the next generation SCSI driver for Microsemi Corp. The smartpqi -driver is the first SCSI driver to implement the PQI queuing model. - -The smartpqi driver will replace the aacraid driver for Adaptec Series 9 -controllers. Customers running an older kernel (Pre-4.9) using an Adaptec -Series 9 controller will have to configure the smartpqi driver or their -volumes will not be added to the OS. - -For Microsemi smartpqi controller support, enable the smartpqi driver -when configuring the kernel. - -For more information on the PQI Queuing Interface, please see: -http://www.t10.org/drafts.htm -http://www.t10.org/members/w_pqi2.htm - -Supported devices: ------------------- -<Controller names to be added as they become publicly available.> - -smartpqi specific entries in /sys ------------------------------ - - smartpqi host attributes: - ------------------------- - /sys/class/scsi_host/host*/rescan - /sys/class/scsi_host/host*/driver_version - - The host rescan attribute is a write only attribute. Writing to this - attribute will trigger the driver to scan for new, changed, or removed - devices and notify the SCSI mid-layer of any changes detected. - - The version attribute is read-only and will return the driver version - and the controller firmware version. - For example: - driver: 0.9.13-370 - firmware: 0.01-522 - - smartpqi sas device attributes - ------------------------------ - HBA devices are added to the SAS transport layer. These attributes are - automatically added by the SAS transport layer. - - /sys/class/sas_device/end_device-X:X/sas_address - /sys/class/sas_device/end_device-X:X/enclosure_identifier - /sys/class/sas_device/end_device-X:X/scsi_target_id - -smartpqi specific ioctls: -------------------------- - - For compatibility with applications written for the cciss protocol. - - CCISS_DEREGDISK - CCISS_REGNEWDISK - CCISS_REGNEWD - - The above three ioctls all do exactly the same thing, which is to cause the driver - to rescan for new devices. This does exactly the same thing as writing to the - smartpqi specific host "rescan" attribute. - - CCISS_GETPCIINFO - - Returns PCI domain, bus, device and function and "board ID" (PCI subsystem ID). - - CCISS_GETDRIVVER - - Returns driver version in three bytes encoded as: - (DRIVER_MAJOR << 28) | (DRIVER_MINOR << 24) | (DRIVER_RELEASE << 16) | DRIVER_REVISION; - - CCISS_PASSTHRU - - Allows "BMIC" and "CISS" commands to be passed through to the Smart Storage Array. - These are used extensively by the SSA Array Configuration Utility, SNMP storage - agents, etc. - |
