NAME
mapdev - Map disk instance names to device names and vice-versa
SYNOPSIS
mapdev mapdev [ instance | dev ... ]
DESCRIPTION
mapdev converts instance names to device names and vice-versa. 'Vanilla' SCSI disks, floppy disks, cdroms, SSA, A1000, A3000, A3500 and A5000 disks, tapes and NFS mounts are all catered for. With no arguments mapdev prints a list of all the mappings. With an argument like 'sdNNN', 'ssdNNN', 'nfsNNN', 'stNNN' etc it will display the corresponding device name. With an argument that looks like 'cNtNdNsN', 'rmt/N' or 'host:/nfs/share' it will print the corresponding sd, sdd, mt or nfs instance name. If the standard input is a pipe, it will convert any instance names to the corresponding device names, preserving column alignment as far as possible.
OPERANDS
The following operands are supported:
- instance name
-
An instance name, e.g. as reported by
'sar -d'
. This will be converted to the corresponding device name. - device name
-
A device name without the leading "/dev/..." prefix. This will be converted into the corresponding instance name.
