Name

blk2scsa– SCSA block device emulation

Description

The blk2scsa module provides support services for generic block devices so that they appear to the system as devices on a virtual SCSI bus, thus allowing them to be serviced by the sd(7D) SCSI disk driver. The blk2scsa device supports the SCSI-2 command set for Direct Access Devices. The blk2scsa device supports multiple LUNs per physical device and creates a separate child device for each LUN. All child nodes attach to sd(7D).

Device Special Files

Disk block special file names are located in /dev/dsk. Raw file names are located in /dev/rdsk. See sd(7D).

ioctls

See dkio(7I)

Errors

See sd(7D).

Files

Device special files for the storage device are created in the same way as those for a SCSI disk. See sd(7D) for more information.

/dev/dsk/cntndnsn

Block files for disks.

/dev/rdsk/ctndnsn

Raw files for disks.
