#  This file gives iostat and sadc a clue about how to find whole
#   disk devices in /proc/partitions and /proc/diskstats
#
# line format, general record:
#   major:name:ctrlpre:ctrlno:devfmt:devcnt:partpre:partcnt:description
#
#  major:		major # for device
#  name:		base of device name
#  ctrlpre:		string to use in generating controller designators
#			 eg: the c in c0d2p6, decimal formatting implied
#                        '*' means none or irrelevant
#  ctrlno:		which controller of this type is this
#  devfmt:		type of device naming convention
#	a:		alpha: xxa, xxb, ... xxaa, xxab, ... xxzz
#       x:		exception... record contains a specific name
#                        for a specific minor #, stored in the devcnt field
#	%string:	string to use in generating drive designators,
#			 eg: the 'd' in c0d2p6 , decimal formatting implied
#	d:		no special translations (decimal formatting)
#  devcnt:		how many whole devs per major number
#  partpre:         	appended to whole dev before part designator
#                        eg. the p in c0d2p6, decimal formatting implied
#			 '*' means none
#  partcnt:		number of partitions per volume
#			 or minor # for exception records
#  description:		informative text
#
# line format, indirect record:
#   major:base_major:ctrlno[:[desc]]
#
#  major:		major number of the device
#  base_major:		major number of the template for this type,
#			 0 for not supported
#  ctrlno:		controller number of this type
#  desc:		controller-specific description
#			if absent the desc from base_major will be
#			 used in sprintf( buf, desc, ctrlno )
