Solaris Express SAN Configuration and Multipathing Guide

Displaying Device Name Changes

The stmsboot(1M) command, available on Solaris Express Developer's Edition OS SPARC, x86 and x64 platforms, can be used to display the mapping between non-multipathed and multipathed device names, after the changes made to the multipath configuration by invoking stmsboot with the -e, -d, or -u option. Both the non-multipathed and the multipathed device names must exist in order to show the mapping.

The -L option displays the mapping of devices on all controllers.


# stmsboot -L
non-STMS device name                    STMS device name
----------------------------------------------------------------
/dev/rdsk/c2t8d0     /dev/rdsk/c10t500000E01046DEE0d0
/dev/rdsk/c2t0d0     /dev/rdsk/c10t500000E01046B070d0
/dev/rdsk/c2t3d0     /dev/rdsk/c10t20000020372A40AFd0
/dev/rdsk/c2t12d0    /dev/rdsk/c10t500000E01046DEF0d0
/dev/rdsk/c2t11d0    /dev/rdsk/c10t500000E01046E390d0
/dev/rdsk/c3t8d0     /dev/rdsk/c10t500000E01046DEE0d0
/dev/rdsk/c3t0d0     /dev/rdsk/c10t500000E01046B070d0
/dev/rdsk/c3t3d0     /dev/rdsk/c10t20000020372A40AFd0
/dev/rdsk/c3t12d0    /dev/rdsk/c10t500000E01046DEF0d0
/dev/rdsk/c3t11d0    /dev/rdsk/c10t500000E01046E390d0

The -l option displays the mapping of devices on only the specified controller. The following example displays the mapping of controller 3.


# stmsboot -l3
non-STMS device name                    STMS device name
----------------------------------------------------------------
/dev/rdsk/c3t8d0    /dev/rdsk/c10t500000E01046DEE0d0
