Setting up the VxVM Environment
Using vxinstall

• For example, the VID:PID combination for an ACME Z1 disk array would be specified as
ACME:Z1.
• Option 4 prevents VxVM from defining a set of paths, or pathgroup, for disks that are not
multipathed by VxVM. (A pathgroup specifies a set of paths that VxVM should recognize as a
single path. Only one path is made visible from a pathgroup.)
• Option 5 excludes devices by preventing VxVM from applying dynamic multipathing (DMP) to
all disks on a controller. The controller you name is excluded from DMP control.
• Option 6 excludes a specified path from dynamic multipathing. For the path you specify, the
corresponding disks are claimed in the OTHER_DISKS category and are not multipathed.
• Option 7 excludes devices by preventing VxVM from applying dynamic multipathing to disks
specified by a VID:PID combination. All disks returning a VID:PID combination are claimed in
the OTHER_DISKS category and are not multipathed.
• Option 8 lists devices that have either been suppressed from the view of VxVM, or that have been
excluded from dynamic multipathing.
If you select any one of options 1 through 7, you must reboot the system for Device Exclusion to take
effect, and then re-run vxinstall.
