The following list brieﬂy summarizes each operation. Additional explanatory

information about each operation is displayed when you enter a choice, and you are

always given the opportunity to exit from the menu before executing the choice.

- 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.)

- For example, the VID:PID combination for an ACME Z1 disk array would be

speciﬁed as ACME:Z1.
