Slice Tables

A partition definition keyword is assigned the name of the slice table. Enclose the name in double quotes to preserve any white space in the name. Table 25-9 describes the identifiers that must be assigned values in all slice tables.

Table 25-9 Required Identifiers for Slice Tables


Identifier	Description
`disk`	The name of the `disk_type` that this slice table is defined for. This name must appear exactly as it does in the `disk_type` definition.
`ctlr`	The disk controller type this slice table can be attached to. Currently, the supported values for this assignment are ISP-80 for IPI controllers and SCSI for SCSI controllers. The controller type specified here must also be defined for the `disk_type` chosen above.

The other assignments in a slice definition describe the actual slice information. The identifiers are the numbers 0 through 7. These assignments are optional. Any slice not explicitly assigned is set to 0 length. The value of each of these assignments is a pair of numbers separated by a comma. The first number is the starting cylinder for the slice, and the second is the number of sectors in the slice. Below are some examples of slice definitions:

partition = "SUN0535" \
	: disk = "SUN0535" : ctlr = SCSI \
	: 0 = 0, 64400 : 1 = 115, 103600 : 2 = 0, 1044960 : 6 = 300, 876960
partition = "SUN0669" \
	: disk = "SUN0669" : ctlr = SCSI \
	: 0 = 0, 32400 : 1 = 40, 64800 : 2 = 0, 1307340 : 6 = 120, 1210140
partition = "SUN1.0G" \
	: disk = "SUN1.0G" : ctlr = SCSI \
	: 0 = 0, 32400 : 1 = 27, 64800 : 2 = 0, 2043600 : 6 = 81, 1946400
