New page

When providing statistics on block devices in Solaris, utilities like ''sar'' and ''kstat'' return instance numbers instead of device names. Converting these to device names can be difficult, especially for NFS file systems. Example:
$ '''sar -d'''
...
nfs1 0 0.0 0 0 0.0 0.0
nfs2 0 0.0 0 0 0.0 0.0
nfs3 0 0.0 0 0 0.0 0.0
nfs4 0 0.0 0 0 0.7 19.2
nfs5 0 0.0 0 0 2.5 15.3
...

In the above output, which file system corresponds to ''nfs1''? To find out, we have to look at the ''dev='' value in ''/etc/mnttab'' and perform a hexadecimal conversion. Fortunately, there is a Perl script named ''[http://search.cpan.org/~aburlison/Solaris-0.05a/ mapdev]'' that performs this conversion.

== Step-by-step instructions for running ''mapdev'' ==

In this example, I run ''mapdev'' out of my current directory. You may instead put ''MapDev.pm'' in @INC and modify the instructions accordingly.

* Download ''[http://search.cpan.org/CPAN/authors/id/A/AB/ABURLISON/Solaris-0.05a.tar.gz mapdev]''.
* Extract ''mapdev''.
$ '''gzip -cd Solaris-0.05a.tar.gz | tar xvf -'''
* Move ''MapDev.pm'' and ''mapdev'' to the current directory.
$ '''mv Solaris-0.05/MapDev/MapDev.pm .'''
$ '''mv Solaris-0.05/scripts/mapdev .'''
* Modify ''mapdev''. In this example, my version of ''perl'' is located in ''/usr/bin'', not ''/usr/local/bin''.
$ '''sed -e 's@#!/usr/local/bin/perl -w@#!/usr/bin/perl -w@' \
'''-e 's@use Solaris::MapDev qw(:ALL);@use MapDev qw(:ALL);@' mapdev > mapdev.new'''
$ '''mv mapdev.new mapdev'''
* Modify ''MapDev.pm''.
$ '''sed 's@package Solaris::MapDev;@package MapDev;@' MapDev.pm > MapDev.pm.new'''
$ '''mv MapDev.pm.new MapDev.pm'''
* Run ''mapdev''.
$ '''./mapdev'''

* If you would rather see local mount points instead of remote NFS resources, change line 71 in ''MapDev.pm'' from:
my ($special, $fstyp, $opt) = (split(" ", $line))[0,2,3];
