See \fBcfgadm\fR(8) for information regarding attachment points. .sp .LP Each \fBSATA\fR controller's and port multiplier's device port is represented by an attachment point in the device tree. \fBSATA\fR devices, connected and configured in the system are shown as the attachment point name extension. The terms "attachment point" and "\fBSATA\fR port" are used interchangeably in the following description. .sp .LP Attachment points are named through \fBap_id\fRs. All the \fBSATA\fR attachment points \fBap_id\fR consist of a string in the following form: .sp .in +2 .nf sataX/P[.M][::dsk/cXtYd0] .fi .in -2 .sp .LP where .sp .ne 2 .na \fBX\fR .ad .RS 14n is the \fBSATA\fR controller number .RE .sp .ne 2 .na \fBP\fR .ad .RS 14n is the \fBSATA\fR controller's device port number (0 to 31) .RE .sp .ne 2 .na \fBM\fR .ad .RS 14n is the port multiplier's device port number (0 to 14) the port multiplier host port number (15). It is used only when the port multiplier is attached to the \fBSATA\fR controller's device port. .RE .sp .ne 2 .na \fBdev/cXtYd0\fR .ad .RS 14n identifies the attached \fBSATA\fR device .RE .sp .ne 2 .na \fBY\fR .ad .RS 14n is a target number .RE .sp .LP In general, the device identifier is derived from the corresponding logical link for the device in /\fIdev\fR. Because only one \fBLUN\fR (\fBLUN\fR 0) is supported by the \fBSATA\fR device, the "d" component of the device string will always have number 0 (zero). .sp .LP For example, the logical \fBap_id\fR of the device port 4 of the port multiplier connected to the device port 5 of the \fBSATA\fR controller 2 would be: .sp .in +2 .nf sata2/5.4 .fi .in -2 .sp .LP If the \fBSATA\fR disk or \fBCD\fR/\fBDVD\fR device is connected to this attachment point, and the device is configured, the \fIap_id\fR would be: .sp .in +2 .nf sata2/5.4::dsk/c2t645d0 .fi .in -2 .sp .LP The \fIcXtYd0\fR string identifying a device has one-to-one correspondence to the device attachment point. .sp .LP A simple listing of attachment points in the system will include all \fBSATA\fR device ports and attached devices. For example: .sp .in +2 .nf #\fBcfgadm -l\fR Ap_Id Type Receptacle Occupant Condition sata0/0::dev/c0t0d0 disk connected configured ok sata0/1::dev/c0t1d0 disk connected configured ok sata0/2::dev/c0t2d0 cd-dvd connected configured ok sata0/3 sata-port empty unconfigured ok sata1/0 sata-port disconnected unconfigured unknown sata1/1 sata port disconnected unconfigured unknown sata1/2 sata port empty unconfigured ok sata1/3.15 sata-pmult connected configured ok sata1/3.0::dev/c0t512d0 disk connected configured ok sata1/3.1 sata-port empty unconfigured ok sata1/3.2 sata-port empty unconfigured ok sata1/3.3 sata-port empty unconfigured ok usb0/1 unknown empty unconfigured ok usb0/2 unknown empty unconfigured ok .fi .in -2 .sp .sp .LP See \fBcfgadm\fR(8)for more information regarding listing of attachment points. .sp .LP The receptacle state for attachment point at the \fBSATA\fR port have the following meanings: .sp .ne 2 .na \fBempty\fR .ad .RS 16n The \fBSATA\fR port is powered-on and enabled. No device presence was detected on this port. .RE .sp .ne 2 .na \fBdisconnected\fR .ad .RS 16n The \fBSATA\fR port is not enabled or the \fBSATA\fR device presence was detected but no communication with the device was established, or the port has failed. .RE .sp .ne 2 .na \fBconnected\fR .ad .RS 16n The \fBSATA\fR device is detected on the port the communication with the device is established. .RE .sp .LP The occupant (device attached to the \fBSATA\fR port) state have the following meanings: .sp .ne 2 .na \fBconfigured\fR .ad .RS 16n The attached \fBSATA\fR device is configured and ready to use by the operating system. .RE .sp .ne 2 .na \fBunconfigured\fR .ad .RS 16n No device is attached, or the \fBSATA\fR device attached to the \fBSATA\fR port was not yet configured.

It may be disabled and/or powered-off by the system. It is unusable and its condition is unknown. It may be due to the device plugged-in. .RE .sp .ne 2 .na \fBunknown\fR .ad .RS 11n The \fBSATA\fR port is disabled and its condition is unknown. .RE .sp .LP A "state table" is the combination of an attachment point receptacle state, an occupant state, and an attachment point (\fBSATA\fR port) condition. The valid states are: .sp .ne 2 .na \fBempty/unconfigured/ok\fR .ad .sp .6 .RS 4n The \fBSATA\fR port is enabled and active. No device presence was detected. .RE .sp .ne 2 .na \fBdisconnected/unconfigured/ok\fR .ad .sp .6 .RS 4n The \fBSATA\fR port is enabled and a device presence was detected but no communications with the device was established. .RE .sp .ne 2 .na \fBdisconnected/unconfigured/unknown\fR .ad .sp .6 .RS 4n The \fBSATA\fR Port is disabled and its condition is unknown. .RE .sp .ne 2 .na \fBdisconnected/unconfigured/failed\fR .ad .sp .6 .RS 4n The \fBSATA\fR Port is disabled and unusable. The port was disabled by the system due to a system-detected failure. .RE .sp .ne 2 .na \fBconnected/unconfigured/ok\fR .ad .sp .6 .RS 4n The \fBSATA\fR Port is enabled and active.

These operations include testing, (\fB-t\fR), invoking configuration state changes, (\fB-c\fR), invoking hardware specific functions (\fB-x\fR), and obtaining configuration administration help messages (\fB-h\fR). .sp .ne 2 .na \fB\fB-c\fR \fIfunction\fR\fR .ad .sp .6 .RS 4n The following generic \fIfunction\fRs are defined for the \fBSATA\fR hardware specific library. For \fBSATA\fR port attachment point, the following configuration state change operations are supported: .sp .ne 2 .na \fBconnect\fR .ad .sp .6 .RS 4n Enable (activate) the \fBSATA\fR port and establish the communication with an attached device. This operation implies powering-on the port if necessary. .RE .sp .ne 2 .na \fBdisconnect\fR .ad .sp .6 .RS 4n Unconfigure the attached device, if it is not already unconfigured, and disable (deactivate) the \fBSATA\fR port. A subsequent "\fBconnect\fR" command enables \fBSATA\fR port operation but does not bring a device to the "configured" state. .RE For a \fBSATA\fR device attached to the \fBSATA\fR port following state change operations are supported: .sp .ne 2 .na \fBconfigure\fR .ad .RS 15n Configure new device for use by the operating system if it is not already configured. This command also implies connect operation, if necessary. .RE .sp .ne 2 .na \fBunconfigure\fR .ad .RS 15n Unconfigure the device connected to the \fBSATA\fR port if it is not already unconfigured. .RE The \fBconfigure\fR and \fBunconfigure\fR operations cannot be used for an attachment point where the port multiplier is connected. Port multipliers are configured and unconfigured automatically by the system. However, configure and unconfigure operations apply to all \fBSATA\fR devices connected to the port multiplier's device ports. .RE .sp .ne 2 .na \fB\fB-f\fR\fR .ad .sp .6 .RS 4n Not supported. .RE .sp .ne 2 .na \fB\fB-h\fR \fIap_id\fR\fR .ad .sp .6 .RS 4n \fBSATA\fR specific help can be obtained by using the help option with any \fBSATA\fR attachment point. .RE .sp .ne 2 .na \fB\fB-l\fR [\fB-v\fR]\fR .ad .sp .6 .RS 4n The \fB-l\fR option works as described in \fBcfgadm\fR(8). When paired with the \fB-v\fR option, the "Information" field contains the following \fBSATA\fR-specific information: .RS +4 .TP .ie t \(bu .el o Mfg: manufacturer string .RE .RS +4 .TP .ie t \(bu .el o Product: product string .RE .RS +4 .TP .ie t \(bu .el o No: product Serial Number .RE .RE .sp .ne 2 .na \fB\fB-o\fR \fIhardware_options\fR\fR .ad .sp .6 .RS 4n No hardware specific options are currently defined. .RE .sp .ne 2 .na \fB\fB-s\fR \fIlisting_options\fR\fR .ad .sp .6 .RS 4n Attachment points of class \fBSATA\fR can be listed by using the select suboption. See \fBcfgadm\fR(8). .RE .sp .ne 2 .na \fB\fB-t\fR \fIap_id\fR\fR .ad .sp .6 .RS 4n Perform self-test of the \fBSATA\fR port, if supported by the \fBSATA\fR controller. If a port self-test operation is not supported by the \fBSATA\fR controller, an error message is issued. .RE .sp .ne 2 .na \fB\fB-x\fR \fIhardware_function\fR\fR .ad .sp .6 .RS 4n Perform hardware specific function. .sp Some of the following commands used on the \fBSATA\fR ports or the \fBSATA\fR controller may affect any \fBSATA\fR devices that have been attached, as noted. \fBap_id\fR refers to \fBSATA\fR port or the entire \fBSATA\fR controller, as noted. If the operation implies unconfiguring a device, but it cannot be unconfigured (that is, the device contains a mounted filesystem), an error message is issued and the operation is not performed. An error message will be also issued if the \fBSATA\fR controller does not support specified operation. .sp .ne 2 .na \fBsata_reset_device ap_id\fR .ad .sp .6 .RS 4n Reset the \fBSATA\fR device attached to \fBap_id\fR \fBSATA\fR port. The \fBSATA\fR port state does not change. .RE .sp .ne 2 .na \fBsata_reset_port ap_id\fR .ad .sp .6 .RS 4n Reset the \fBSATA\fR port specified by \fBap_id\fR. If a \fBSATA\fR device is attached to the port, it is also reset. This operation may be also performed on the port to which a port multiplier is connected. If a port multiplier is connected to the \fBSATA\fR controller port, the \fBSATA\fR devices attached to the port multiplier may not be reset .RE .sp .ne 2 .na \fBsata_reset_all ap_id\fR .ad .sp .6 .RS 4n Reset \fBSATA\fR controller specified by the controller number part in \fBap_id\fR and all attached devices and re-enumerate all connected devices, including port multipliers and devices connected to port multipliers' device ports. .sp This operations implies unconfiguring all attached devices prior to the operation. Any newly enumerated devices will be left unconfigured. .RE .sp .ne 2 .na \fBsata_port_deactivate ap_id\fR .ad .sp .6 .RS 4n Force the deactivation of the port when all else fails. This is meant as an emergency step; use with caution. .RE .sp .ne 2 .na \fBsata_port_activate ap_id\fR .ad .sp .6 .RS 4n Force the activation of a port. This is meant for emergency situations on a port which was deactivated to recover from errors. .RE .sp .ne 2 .na \fBsata_port_self_test ap_id\fR .ad .sp .6 .RS 4n Perform self-test operation on the \fBSATA\fR controller. This operation implies unconfiguring all devices and resetting the \fBSATA\fR controller. .RE .RE .sp .ne 2 .na \fB\fB-v\fR\fR .ad .sp .6 .RS 4n Execute in verbose mode. .sp The following Transitions table reports the state transitions resulting from the \fB-c\fR operations and hotplugging actions: .sp .in +2 .nf current state operation possible new state ------------- --------- ------------------ empty/ unconfigured/ok device plug-in connected/unconfigured/ok, or disconnected/unconfigured/ok, or disconnected/unconfigured/failed empty/ unconfigured/ok -c unconfigure error message, no state change empty/ unconfigured/ok -c configure error message, no state change empty/ unconfigured/ok -c connect error message, no state change empty/ unconfigured/ok -c disconnect disconnected/unconfigured/unknown, or disconnected/unconfigured/failed disconnected/ unconfigured/ok device unplug no state change disconnected/ unconfigured/ok -c unconfigure error message, no state change disconnected/ unconfigured/ok -c configure error message, no state change disconnected/ unconfigured/ok -c connect error message, no state change disconnected/ unconfigured/ok -c disconnect error message, no state change disconnected/ unconfigured/ unknown (no disk plugged) -c configure error message, state change to empty/unconfigured/ok, or disconnected/unconfigured/failed disconnected/ unconfigured/ unknown -c configure state change to (disk plugged) connected/configured/ok or, connected/unconfigured/ok, or disconnected/unconfigured/failed and possible error message disconnected/ unconfigured/ unknown -c connect empty/unconfigured/ok, or connected/unconfigured/ok, or disconnected/unconfigured/ok, or disconnected/unconfigured/unknown, or disconnected/unconfigured/failed disconnected/ unconfigured/ unknown -c disconnect error message, no state change disconnected/ unconfigured/ failed any command error message, no state change other than -x commands connected/ unconfigured/ok disk unplug error message and state: empty/unconfigured/ok, or disconnected/unconfigured/failed connected/ unconfigured/ok -c configure connected/unconfigured/ok, or connected/configured/ok, or disconnected/unconfigured/ok, or disconnected/unconfigured/failed connected/ unconfigured/ok -c unconfigure error message, no state change connected/ unconfigured/ok -c connect error message, no state change connected/ unconfigured/ok -c disconnect disconnected/unconfigured/unknown, or disconnected/unconfigured/failed connected/ configured/ok disk unplug error message and state: empty/unconfigured/ok, or disconnected/unconfigured/failed connected/ configured/ok -c configure error message, no state change connected/ configured/ok -c unconfigure error message, if device cannot be unconfigured, no state change, or connected/unconfigured/ok, or disconnected/unconfigured/ok, or disconnected/unconfigured/failed connected/ configured/ok -c connect error message, no state change connected/ configured/ok -c disconnect error message, if device cannot be unconfigured, no state change, or disconnected/unconfigured/unknown, or disconnected/unconfigured/failed .fi .in -2 .sp .RE .SH EXAMPLES .LP \fBExample 1 \fRConfiguring a Disk .sp .LP The following command configures a disk attached to \fBSATA\fR controller 0, port 0: .sp .in +2 .nf example# \fBcfgadm -c configure sata0/0\fR .fi .in -2 .sp .sp .LP This command should be issued only when there is a device connected to the \fBSATA\fR port. .LP \fBExample 2 \fRUnconfiguring a Disk .sp .LP The following command unconfigures a disk attached to \fBSATA\fR controller 0, port 3: .sp .in +2 .nf example# \fBcfgadm -c unconfigure sata0/3::dsk/c0t3d0\fR .fi .in -2 .sp .sp .LP The device identifying string is shown when the attachment point receptacle state is "connected" and occupant state is "configured". .LP \fBExample 3 \fREncountering a Mounted File System While Unconfiguring a Disk .sp .LP The following command illustrates encountering a mounted file system while unconfiguring a disk: .sp .in +2 .nf example# \fBcfgadm -c unconfigure sata1/5::dsk/c01t35d0\fR .fi .in -2 .sp .sp .LP The system responds with the following: .sp .in +2 .nf cfgadm: Component system is busy, try again: failed to offline: /devices/pci@0,0/pci8086,244e@1e/pci1095,3124@1/sd@5,0 Resource Information ------------------ -------------------------- /dev/dsk/c1t5d0s0 mounted filesystem "/mnt" .fi .in -2 .sp .SH FILES .sp .ne 2 .na \fB/usr/lib/cfgadm/sata.so.1\fR .ad .RS 29n Hardware specific library for generic \fBSATA\fR hot plugging. .RE .SH SEE ALSO .sp .LP .BR config_admin (3CFGADM), .BR libcfgadm (3LIB), .BR attributes (7), .BR cfgadm (8) .SH NOTES .sp .LP The emergency "sata_port_deactivate" operation is not supported on ports with attached disks containing critical partitions such as root (/), /usr, swap, or /var.
