When you physically connect new disks to a host or when you zone new fibre channel devices to a host, you can use the vxdctl enable
command to rebuild the volume device node directories and to update the DMP internal database to reflect the new state of the system.
To reconfigure the DMP database, first reboot the system to make Linux recognize the new disks, and then invoke the vxdctl
enable
command.
See the vxdctl
(1M) manual page.
You can also use the vxdisk
scandisks
command to scan devices in the operating system device tree, and to initiate dynamic reconfiguration of multipathed disks.
If you want VxVM to scan only for new devices that have been added to the system, and for devices that have been enabled or disabled, specify the -f
option to either of the commands, as shown here:
However, a complete scan is initiated if the system configuration has been modified by changes to:
