 Re: Monitoring STMS disk multi pathing In article <1105858730.800815.58470@z14g2000cwz.googlegroups. com>, <co4770@yahoo.com> wrote: > > >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. 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 -- Fredrik Lundholm dol @ ce.chalmers.se      |

Since it is a production server,down time is an issue, in order to physically disable the path and see the performance. Regards |
