2:
3:
4: The COHERENT SCSI series of device drivers lets you use SCSI-interface
5: devices attached to host adapters from several vendors.
6:
7: All COHERENT SCSI device drivers use major number 13, thus allowing all
8: SCSI devices to be accessed via standard device-naming conventions.
9: Peripherals can be accessed as either block- or character-special devices.
10: The minor number specifies the device and partition number for disk-type
11: devices; this allows the use of up to eight SCSI identifiers (SCSI-ID's),
12: with up to four logical unit numbers (LUNs) per SCSI-ID and up to four
13: partitions per LUN. Tape and other special devices decode the minor number
14: to perform special operations such as ``rewind on close'' or ``no rewind on
15: close''.
16:
17: The first ooppeenn call on a SCSI disk device allocates memory for the
18: partition table and reads it into memory.
19:
20: See the release notes for further information regarding supported host
21: adapters and peripherals.
