NAME

       scsa1394 - SCSI to 1394 bridge driver

SYNOPSIS

       unit@GUID

DESCRIPTION

       The  scsa1394 driver is a 1394 target and an SCSA HBA driver that supports 1394 mass storage devices compliant with the Serial Bus Protocol
       2 (SBP-2) specification. It supports both bus-powered and self-powered 1394 mass storage devices.

       The scsa1394 nexus driver maps SCSA target driver requests to SBP-2 Operation Request Blocks (ORB's).

       The scsa1394 driver creates a child device info node for each logical unit (LUN) on the mass storage device. The standard Solaris SCSI disk
       driver is attached to those nodes. Refer to sd(7D).

       This driver supports multiple LUN devices and creates a separate child device info node for each LUN. All child LUN nodes attach to sd(7D).

       All  1394  mass	storage  devices are treated as removable media devices. A 1394 mass storage device can be managed by rmformat(1). With or
       without Volume Manager, you can mount, eject, hot remove and hot insert a 1394 mass storage device, as the following sections explain.

Using Volume Management
       Mass storage devices are managed by Volume Manager. vold(1M) creates a device nickname which can be listed with	eject(1).  The	device	is
       mounted using volrmmount(1) under /rmdisk/label.

       See  volrmmount(1)  to  unmount the device and eject(1) to eject the media. If the device is ejected while it is mounted, vold(1M) unmounts
       the device before ejecting it. It also kills any active applications that are accessing the device.

       Hot removing a mass storage device with vold(1M) active fails with a console warning. To hot remove or insert a 1394 storage device,  first
       stop  vold(1M)  by  issuing the command /etc/init.d/volmgt stop. After the device has been removed or inserted, restart vold(1M) by issuing
       the command /etc/init.d/volmgt start.

       You can also permanently disable vold for removable devices by commenting out the rmscsi line in vold.conf. See the  System  Administration
       Guide, Volume I and Solaris Common Desktop Environment: User's Guide for details on how to manage a removable device with CDE and Removable
       Media Manager. See dtfile.1X under CDE for information on how to use Removable Media Manager.

USING 
mount(1M)  AND umount(1M)
       Use mount(1M)  to mount the device and umount(1M) to unmount the device. Use eject(1) to eject the media. Because vold(1M) is disabled,	no
       vold nicknames can be used.

       Removing  the  storage device while it is being accessed or mounted fails with a console warning. To hot remove the storage device from the
       system, unmount the file system, then kill all applications accessing the device. Next, hot remove the device. A storage device can be  hot
       inserted at any time.

       For a comprehensive listing of (non-bootable) 1394 mass-storage devices that are compatible with this driver, see www.sun.com/io.

DEVICE SPECIAL FILES

       Block special file names are located in /dev/dsk. Raw file names are located in /dev/rdsk. Input/output requests to the devices must follow
       the same restrictions as those for SCSI disks. Refer to sd(7D).

IOCTLS

       Refer to cdio(7I) and dkio(7I).

ERRORS

       Refer to sd(7D).

FILES

       The device special files for the 1394 mass storage device are created like those for a SCSI disk. Refer to sd(7D).

       /dev/dsk/cntndnsn

	   Block files

       /dev/rdsk/cntndnsn

	   Raw files

       /vol/dev/aliases/rmdisk0

	   Symbolic link to the character device for the media in removable drive 0. This is a generic removable media device.

       /kernel/drv/scsa1394

	   32-bit x86 ELF kernel module

       /kernel/drv/amd64/scsa1394

	   64-bit x86 ELF kernel module

       /kernel/drv/sparcv9/scsa1394

	   64-bit SPARC ELF kernel module
