SATA(7D)SATA(7D)NAMEsata - Solaris SATA framework
DESCRIPTION
Serial ATA is an interconnect technology designed to replace parallel
ATA technology. It is used to connect hard drives, optical drives,
removable magnetic media devices and other peripherals to the host sys‐
tem. For complete information on Serial ATA technology, visit the
Serial ATA web site at http://www.serialata.org.
Up to 32 SATA devices may be plugged directly to each SATA HBA and up
to 15 SATA devices may be plugged directly to each SATA port multiplier
supported by the Solaris SATA framework. The actual number of pluggable
devices my be lower, and is limited by the number of device ports on
the SATA HBA or the SATA port multiplier. The maximum data rate is
either 1.5Gb/sec. or 3.0Gb/sec., depending on the capability of a SATA
device, port multiplier and SATA HBA controller.
The Solaris SATA framework adheres to the Serial ATA 1.0a specification
and supports SATA-2 signaling speed 3.0Gb/sec. SATA devices that are
connected to SATA HBAs controlled by a SATA framework-compliant HBA
driver are treated by the system as SCSI devices. The Solaris SCSI disk
driver (sd(7D)) is attached as a target driver for each device node
created by the SATA framework. You can use the cfgadm(1M) utility to
manage hot plugged and unplugged SATA devices.

DIAGNOSTICS
The messages described below may appear on the system console as well
as being logged. All messages are presented in one of the following
formats and are followed by the diagnostic message:
sata: WARNING: <controller/devices/.. path>:
or:
sata: NOTICE: <controller/devices/.. path>:
...where <controller/devices/.. path> identifies a specific SATA HBA
issuing a diagnostic message shown below.
SATA port X: link lost.
Communication (via serial link) between the HBA and the device
plugged to the specified SATA device port has been lost.
SATA port X: link established.
Communication (via serial link) between the HBA and the device
plugged to the specified SATA device port has been established.
SATA port X: device reset.
The device plugged to the specified SATA device port has been
reset. The reset may be due to a communication or command error,
command timeout, or an explicit request from the host.
SATA port X failed.
The specified SATA device port failed and is in an unusable state.
You can change the port state by deactivating the port and activat‐
ing it again using cfgadm SATA hardware-specific commands (see
cfgadm_sata(1M)).
SATA port X error.
An error was detected in specified SATA device port operations.
SATA device detached at port X.
Communication (via serial link) between the HBA and the device
plugged to the specified SATA device port has been lost and could
not be re-established. The SATA framework assumes that the device
is unplugged from the specified SATA device port.
SATA device detected at port X.
Communication( via serial link) between the HBA and the device
plugged to the specified empty SATA device port has been estab‐
lished. The SATA framework assumes that the new device is plugged
to the specified SATA device port.
SATA disk device at port X.
This message is followed by a disk description specifying the disk
vendor, serial number, firmware revision number and the disk capa‐
bilities.
SATA CD/DVD (ATAPI) device at port X.
This message is followed by a SATA CD/DVD description specifying
the DVD vendor, serial number, firmware revision number and the DVD
capabilities.
SATA device at port X cannot be configured. Application(s) accessing
previously attached device have to release it before newly inserted
device can be made accessible.
The port cannot be configured because there is application using
the previous attached device, so the application must release it,
then the newly inserted device can be configured.
Application(s) accessing previously attached SATA device have to
release it before newly inserted device can be made accessible.
The target node remained and it belongs to a previously attached
device. This happens when the file was open or the node was waiting
for resources at the time the associated device was removed.
Instruct event daemon to retry the cleanup later.
sata: error recovery request for non-attached device at cport X.
When error recovery is requested, the device is not yet attached.
SATA device at port X is not power-managed.
When property pm-capable on the target device node setting fails,
the SATA device won't be power-managed.
SATA disk device at port X does not support LBA.
The disk device plugged into specified SATA device port does not
support LBA addressing and cannot be used.
Cannot identify SATA device at port X - device is attached.
IDENTIFY (PACKET) DEVICE data cannot be retrieved successfully
after the device is attached to the SATA port.
sata: <HBA driver name><instance number>:hba attached failed.
The SATA HBA instance attach operation failed. This HBA instance
cannot be configured and is not available.
sata: invalid ATAPI cdb length<command cdb length>.
The length of the command cdb is greater than that the device can
support.
sata: invalid sata_hba_tran version X for driver <HBA driver name>.
The specified SATA HBA driver and the SATA framework are incompati‐
ble. The driver cannot attach and SATA HBAs controlled by this
driver (and devices plugged to this SATA HBA ports) are not avail‐
able.
sata_hba_attach: cannot create SATA attachment point for port X.
The specified SATA device port cannot be configured in the system
and a device plugged to this port could not be not be configured
and used.
sata_create_target_node: cannot create target node for device at port
X.
The device target node for the device plugged to the specified SATA
device port could not be created. As a result, the device cannot be
configured and used.
