NAME

mapdev - Map disk instance names to device names and vice-versa

SYNOPSIS

mapdev mapdev [ instance | dev ... ] mapdev -explorer <explorer dir> mapdev -explorer <explorer dir> [ 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:

-explorer <explorer directory>

Mapping information is derived from the files in the explorer directory, rather than the "live" files on the system.

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.

EXAMPLES

 $ mapdev
 nfs132 is an alias for homesvr:/export/home/alan
 nfs2 is an alias for mailsvr:/var/mail
 nfs3 is an alias for workstation:vold(pid315)
 sd0 is an alias for c0t0d0
 sd8 is an alias for c0t9d0
 sd9 is an alias for c0t10d0
 st1 is an alias for mt0
 st2 is an alias for mt1

 $ mapdev nfs132 sd9,d c0t0d0s3
 homesvr:/export/home/alan c0t10d0s3 sd0,d
