If you have two SANS paths zones on your sans fabric zones you will see the same device show twice in your format command so you run: stmsboot -e
Example 2 Disabling Solaris I/O Multipathing use stmsboot -d Also the format will show only one deice path showing if enabled. and so depending how you have /kernek/drv/scsi_vhci.conf set # Load balancing global configuration: setting load-balance="none" will cause # all I/O to a given device (which supports multipath I/O) to occur via one # path. Setting load-balance="round-robin" will cause each path to the device # to be used in turn. # load-balance="round-robin"; # # Automatic failback configuration # possible values are auto-failback="enable" or auto-failback="disable" auto-failback="enable"; this will allow for load balancing or fail over path have a backup path for your SANS connection luxadm probe luxadm display /dev/rdsk/cxtx000000xxxxxxxxxxxs2 -- This message posted from opensolaris.org
