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.
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.
You can also permanently disable vold for removable devices by commenting out the rmdsk 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.
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.
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).
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).
Symbolic link to the character device for the media in removable drive 0. This is a generic removable media device.
