Verifying I/O fencing configuration

Last published : Jun 11, 2026
Verify from the vxfenadm output that the SCSI-3 disk policy reflects the configuration in the /etc/vxfenmode file.
To verify I/O fencing configuration
  1. On one of the nodes, type:
    \# vxfenadm -d
    Output similar to the following appears if the fencing mode is SCSI3 and the SCSI3 disk policy is dmp:
