DESCRIPTION
The SATA hardware specific library, /usr/lib/cfgadm/sata.so.1, provides the functionality for SATA hot plugging through the cfgadm command. cfgadm operates on attachment points, which are locations in thesystem where hardware resources can be dynamically reconfig-
ured. See cfgadm(1M) for information regarding attachment points. Each SATA controller's and port multiplier's device port is represented by an attachment point in the device tree. SATA devices, connected and configured in the system are shown as the attachment point name extension. The terms "attachmentpoint" and "SATA port" are used interchangeably in the fol-
lowing description.Attachment points are named through ap_ids. All the SATA
attachment points ap_id consist of a string in the following
form:sataX/P[.M][::dsk/cXtYd0] where X is the SATA controller number

System Administration Commands cfgadm_sata(1M)
P is the SATA controller's device port number (0 to 31) M 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 SATA controller's device port. dev/cXtYd0 identifies the attached SATA device Y is a target number In general, the device identifier is derived from the corresponding logical link for the device in /dev. Because only one LUN (LUN 0) is supported by the SATA device, the "d" component of the device string will always have number 0 (zero).For example, the logical ap_id of the device port 4 of the
port multiplier connected to the device port 5 of the SATA controller 2 would be: sata2/5.4If the SATA disk or CD/DVD device is connected to this
attachment point, and the device is configured, the ap_id
would be: sata2/5.4::dsk/c2t645d0The cXtYd0 string identifying a device has one-to-one
correspondence to the device attachment point. A simple listing of attachment points in the system will include all SATA device ports and attached devices. For example:#cfgadm -l

The attachment point (SATA port) condition have the follow-
ing meanings:ok The SATA port is powered-on and enabled, and is
ready for use. failed The SATA port failed. It may be disabled and/orpowered-off by the system. It is unusable and its
condition is unknown. It may be due to the deviceplugged-in.
unknown The SATA port is disabled and its condition is unknown. A "state table" is the combination of an attachment point receptacle state, an occupant state, and an attachment point (SATA port) condition. The valid states are: empty/unconfigured/ok The SATA port is enabled and active. No device presence was detected. disconnected/unconfigured/ok The SATA port is enabled and a device presence wasdetected but no communications with the device was esta-
blished. disconnected/unconfigured/unknown The SATA Port is disabled and its condition is unknown. disconnected/unconfigured/failed The SATA Port is disabled and unusable. The port wasdisabled by the system due to a system-detected failure.
connected/unconfigured/ok The SATA Port is enabled and active. A device presence was detected and the communication with a device was established. The device is not configured to be used by the OS.SunOS 5.11 Last change: 27 Aug 2007 4

connected/configured/ok The device is present and configured, and is ready to use by the OS. OPTIONS cfgadm defines several types of operations besides listing(-l). These operations include testing, (-t), invoking con-
figuration state changes, (-c), invoking hardware specific
functions (-x), and obtaining configuration administration
help messages (-h).
-c function
The following generic functions are defined for the SATA hardware specific library. For SATA port attachmentpoint, the following configuration state change opera-
tions are supported: connect Enable (activate) the SATA port and establish thecommunication with an attached device. This opera-
tion implies powering-on the port if necessary.
disconnect Unconfigure the attached device, if it is not already unconfigured, and disable (deactivate) the SATA port. A subsequent "connect" command enables SATA port operation but does not bring a device to the "configured" state. For a SATA device attached to the SATA port following state change operations are supported: configure Configure new device for use by the operating system if it is not already configured. This command also implies connect operation, if necessary. unconfigure Unconfigure the device connected to theSATA port if it is not already unconfig-
ured. The configure and unconfigure operations cannot be used for an attachment point where the port multiplier isconnected. Port multipliers are configured and unconfig-
ured automatically by the system. However, configure andSunOS 5.11 Last change: 27 Aug 2007 5

unconfigure operations apply to all SATA devices con-
nected to the port multiplier's device ports.-f
Not supported.-h ap_id
SATA specific help can be obtained by using the help option with any SATA attachment point.-l [-v]
The -l option works as described in cfgadm(1M). When
paired with the -v option, the "Information" field con-
tains the following SATA-specific information:
o Mfg: manufacturer string o Product: product string o No: product Serial Number-o hardware_options
No hardware specific options are currently defined.-s listing_options
Attachment points of class SATA can be listed by using the select suboption. See cfgadm(1M).-t ap_id
Perform self-test of the SATA port, if supported by the
SATA controller. If a port self-test operation is not
supported by the SATA controller, an error message is issued.-x hardware_function

the SATA controller may affect any SATA devices thathave been attached, as noted. ap_id refers to SATA port
or the entire SATA controller, as noted. If the opera-
tion implies unconfiguring a device, but it cannot be unconfigured (that is, the device contains a mountedfilesystem), an error message is issued and the opera-
tion is not performed. An error message will be also issued if the SATA controller does not support specified operation.sata_reset_device ap_id
Reset the SATA device attached to ap_id SATA port.
The SATA port state does not change.sata_reset_port ap_id
Reset the SATA port specified by ap_id. If a SATA
device is attached to the port, it is also reset. This operation may be also performed on the port towhich a port multiplier is connected. If a port mul-
tiplier is connected to the SATA controller port, the SATA devices attached to the port multiplier may not be resetsata_reset_all ap_id
Reset SATA controller specified by the controllernumber part in ap_id and all attached devices and
re-enumerate all connected devices, including port
multipliers and devices connected to port multi-
pliers' device ports. This operations implies unconfiguring all attached devices prior to the operation. Any newly enumerated devices will be left unconfigured.sata_port_deactivate ap_id
Force the deactivation of the port when all else fails. This is meant as an emergency step; use with caution.sata_port_activate ap_id
Force the activation of a port. This is meant for emergency situations on a port which was deactivated to recover from errors.SunOS 5.11 Last change: 27 Aug 2007 7

This command should be issued only when there is a device connected to the SATA port. Example 2 Unconfiguring a Disk The following command unconfigures a disk attached to SATA controller 0, port 3:example# cfgadm -c unconfigure sata0/3::dsk/c0t3d0

NOTESThe emergency "sata_port_deactivate" operation is not sup-
ported on ports with attached disks containing critical par-
titions such as root (/), /usr, swap, or /var. The deac-
tivate operation should not be attempted on such ports. Incorrect usage can result in a system hang and require a reboot.Hotplugging operations are not supported by all SATA con-
trollers.If SATA connectors are the hot-pluggable type and the SATA
controller supports hotplugging, a SATA device can be hot-
plugged at any time. The system detects the event and estab-
lishes the communication with the device. The device has tobe configured by the explicit "cfgadm -c configure ap_id"
command.If the SATA connectors are the hot-pluggable type and the
SATA controller supports hotplugging, unplugging a device without unconfiguring it may result in system hang or data loss. If a device is unconfigured but receptacle state is not in a disconnected state, unplugging a device from the SATA port will result in error message. WARNINGS The connectors on some SATA devices do not conform to SATA hotplug specifications. Performing hotplug operations on such devices can cause damage to the SATA controller and/or the SATA device.SunOS 5.11 Last change: 27 Aug 2007 12
