Hi,

I have STMS enabled for mutipathing using FC-AL disks and X6727A HBA.
Disks are mirrored using Traffic manager paths

Can I see both paths working and it's performance.Appreciate some tips.
Regards

In article <1105858730....@z14g2000cwz.googlegroups.com>,

The command 'luxadm probe' will show the virtual paths. If you do a
'luxadm display {pathname}' it will show the underlying physical paths.

The performance is often measured on the disk array of fibre channel switches.
In solaris 'iostat -tcx 5' is a nice tool, however I don't think it will show
traffic on the physical paths.

You could always dispable one path and ee if that impacts your application
performance.

/Regards
Fredrik

Thanks for the reply, I am still wondering if there is any STMS command
monitoring both paths. Since it is a production server,down time is an
issue, in order to physically disable the path and see the performance.

You can watch the performance down both/all paths with "iostat -X". if
you want to monitor the status of the paths you'll have to grok the
/var/adm/messages output or look at luxadm output within some delta.
