Step 1. Select menu item 3 (Prevent Multipathing/Suppress devices from VxVM’s view) from the vxinstall
main menu.
The following message displays:

This operation might lead to some devices being suppressed from VxVM’s view or prevent them
from being multipathed by vxdmp. (This operation can be reversed using the vxdiskadm command).
Do you want to continue? [y,n,q,?] (default: n) y
Step 2. Enter y.

• Option 1 prevents VxVM from using all paths through a specified controller. The specified
controller is disabled.
• Option 2 prevents VxVM from using one or more specified paths. The specified path is excluded
from VxVM control
• Option 3 prevents VxVM from using one or more disks specified by a VID:PID combination,
where VID stands for a Vendor ID, and PID stands for Product ID. (The command
/etc/vx/diag.d/vxdmping can be used to obtain these IDs. This command displays the
standard SCSI inquiry data returned from the disk controller.)
