About administering I/O fencing
The I/O fencing feature provides the following utilities that are available through the VRTSvxfen
RPM:
vxfentsthdw | Tests SCSI-3 functionality of the disks for I/O fencing |
vxfenconfig | Configures and unconfigures I/O fencing Lists the coordination points used by the vxfen driver. |
vxfenadm | Displays information on I/O fencing operations and manages SCSI-3 disk registrations and reservations for I/O fencing |
vxfenclearpre | Removes SCSI-3 registrations and reservations from disks |
vxfenswap | Replaces coordination points without stopping I/O fencing |
vxfendisk | Generates the list of paths of disks in the disk group. This utility requires that Veritas Volume Manager (VxVM) is installed and configured. |
The I/O fencing commands reside in the /opt/VRTS/bin folder. Make sure you added this folder path to the PATH environment variable.
Refer to the corresponding manual page for more information on the commands.
