You should go back to 'mpxio-disable="no";' and look at 'prtconf -v /dev/rdsk/XXX' - you should see the multiple paths 'virtualized' below a single /devices/scsi_vhci disk node. For symetric devices the scsi_vhci code takes care of spreading the load over available paths. See scsi_vhci(7d), and mpathadm(1M). http://www.opensolaris.org/os/project/mpxio/ -Chris > Thanks, > Krutibas > > > Peter Tribble wrote: > >> On Wed, May 21, 2008 at 9:54 AM, Krutibas Biswal <[EMAIL PROTECTED]> wrote: >> >>> I am trying to bringup a 3510 JBOD on Solaris 10 and would like to enable >>> multipathing.
