About the vxfenadm utility
Administrators can use the vxfenadm command to troubleshoot and test fencing configurations.
The command's options for use by administrators are as follows:
-s | read the keys on a disk and display the keys in numeric, character, and node format Note: The -g and -G options are deprecated. Use the -s option. |
-i | read SCSI inquiry information from device |
-m | register with disks |
-n | make a reservation with disks |
-p | remove registrations made by other systems |
-r | read reservations |
-x | remove registrations |
Refer to the vxfenadm(1M) manual page for a complete list of the command options.
