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).


     In previous releases, all 1394  mass  storage  devices  were
     treated  as  removable  media  devices and managed by rmfor-
     mat(1)  and  volume  management  software.  In  the  current
     release, however, only mass storage devices with a removable
     bit (RMB) value of 1 are removable. (The RMB is part of  the
     device's   SCSI   INQUIRY  data.)  See  SCSI  specifications
     T10/995D Revision 11a, T10/1236-D Revision 20 or  T10/1416-D
     Revision 23 for more information. However, for backward com-
     patibility, all 1394  mass  storage  devices  can  still  be
     managed  by  rmformat(1). With or without a 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  a  volume  manager.
     Software that manages removable media creates a device nick-
     name that can be listed with eject(1) or rmmount(1). A  dev-
     ice  that  is not mounted automatically can be mounted using
     rmmount(1) under /rmdisk/label. Note that the mount(1M)  and
     mount(1M)  commands  do  not  accept nicknames; you must use
     explicit device names with these commands.

     See rmmount(1) to unmount the device and eject(1)  to  eject
     the  media.  If  the  device is ejected while it is mounted,
     volume management software unmounts the device before eject-
     ing  it. It also might kill any active applications that are
     accessing the device.


     Volume management software  is  hotplug-aware  and  normally
     mounts  file systems on USB mass storage devices if the file
     system is recognized. Before hot removing  the  USB  device,
     use eject(1) to unmount the file system.


     You can disable the automatic  mounting  and  unmounting  of
     removable  devices by inserting a entry for a removable dev-
     ice in /etc/vfstab. In this entry, you must set the mount at
     boot  field to no. See vfstab(4). See the System Administra-
     tion Guide, Volume I.

USING mount AND umount
     Use mount(1M) to explicitly mount the device and  umount(1M)
     to  unmount  the  device.  Use  eject(1) to eject the media.
     After you have explicitly mounted a  removable  device,  you
     cannot use a nickname as an argument to eject.


     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.

     storage  devices  that  are compatible with this driver, see

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).

     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.
