# This file gives iostat, sar, and sadf a clue about how to find whole
# disk devices in /proc/diskstats.
# Authoritative source is: linux/Documentation/devices.txt or
# linux/Documentation/admin-guide/devices.txt
#
# 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
# 'x': exception... record contains a specific name
# for a specific minor #, stored in the ctrlno field
# ctrlno: which controller of this type is this
# devfmt: type of device naming convention
# a: alpha: xxa, xxb, ... xxaa, xxab, ... xxzz
# %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 )
