Storage controllers. -.SS Supported \f[BI]ioctl\fP\/() operations -For compatibility with applications written for the -.BR cciss (4) -and -.BR hpsa (4) -drivers, many, but not all of the -.BR ioctl (2) -operations supported by the -.B hpsa -driver are also supported by the -.B smartpqi -driver. -The data structures used by these operations -are described in the Linux kernel source file -.IR include/linux/cciss_ioctl.h . -.TP -.B CCISS_DEREGDISK -.TQ -.B CCISS_REGNEWDISK -.TQ -.B CCISS_REGNEWD -These operations -all do exactly the same thing, which is to cause the driver to re-scan -for new devices. -This does exactly the same thing as writing to the -.BR smartpqi -specific -host -.I rescan -attribute. -.TP -.B CCISS_GETPCIINFO -This operation returns the PCI domain, bus, -device, and function and "board ID" (PCI subsystem ID). -.TP -.B CCISS_GETDRIVVER -This operation returns the driver version in four bytes, encoded as: -.IP -.in +4n -.EX -(major_version << 28) | (minor_version << 24) | - (release << 16) | revision -.EE -.in -.TP -.B CCISS_PASSTHRU -Allows BMIC and CISS commands to be passed through to the controller. -.SS Boot options -.TP -.BR disable_device_id_wildcards= { 0 | 1 } -Disables support for device ID wildcards. -The default value is 0 (wildcards are enabled). -.TP -.BR disable_heartbeat= { 0 | 1 } -Disables support for the controller's heartbeat check. -This parameter is used for debugging purposes. -The default value is 0 (the controller's heartbeat check is enabled). -.TP -.BR disable_ctrl_shutdown= { 0 | 1 } -Disables support for shutting down the controller in the -event of a controller lockup. -The default value is 0 (controller will be shut down). -.TP -.BR lockup_action= { none | reboot | panic } -Specifies the action the driver takes when a controller -lockup is detected. -The default action is -.BR none . -.TS -l l ---- -l l. -parameter action -\fBnone\fP take controller offline only -\fBreboot\fP reboot the system -\fBpanic\fP panic the system -.TE -.TP -.BR expose_ld_first= { 0 | 1 } -This option exposes logical devices to the OS before physical devices. -The default value is 0 (physical devices exposed first). -.TP -.BR hide_vsep= { 0 | 1 } -This option disables exposure of the virtual SEP to the OS. -The default value is 0 (virtual SEP is exposed). -.TP -.BR disable_managed_interrupts= { 0 | 1 } -Disables driver utilization of Linux kernel managed interrupts for controllers. -The managed interrupts feature automatically distributes interrupts -to all available CPUs and assigns SMP affinity. -The default value is 0 (managed interrupts enabled). -.TP -.BR ctrl_ready_timeout= { 0 |[ 30 , 1800 ]} -This option specifies the timeout in seconds for the driver to wait -for the controller to be ready. -The valid range is 0 or -.RB [ 30 ", " 1800 ]. -The default value is 0, -which causes the driver to use a timeout of 180 seconds. -.SH FILES -.SS Device nodes -Disk drives are accessed via the SCSI disk driver -.RI ( sd ), -tape drives via the SCSI tape driver -.RI ( st ), -and the RAID controller via the SCSI generic driver -.RI ( sg ), -with device nodes named -.IR /dev/sd *, -.IR /dev/st *, -and -.IR /dev/sg *, -respectively. -.SS SmartPQI-specific host attribute files in \f[BI]/sys\fP -.TP -.IR /sys/class/scsi_host/host * /rescan -The host -.I rescan -attribute is a write-only attribute. -Writing to this attribute will cause the driver to scan for new, -changed, or removed devices (e.g., hot-plugged tape drives, or newly -configured or deleted logical volumes) and notify the SCSI mid-layer of -any changes detected. -Usually this action is triggered automatically by configuration -changes, so the user should not normally have to write to this file. -Doing so may be useful when hot-plugging devices such as tape drives or -entire storage boxes containing pre-configured logical volumes. -.TP -.IR /sys/class/scsi_host/host * /lockup_action -The host -.I lockup_action -attribute is a read/write attribute. -This attribute will cause the driver to perform a specific action in the -unlikely event
