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 Dynamic Multi-Pathing (DMP) internal database to reflect the new state of the system.
To reconfigure the DMP database, first run cfgmgr to make the operating system recognize the new disks, and then invoke the vxdctl enable command.
If you want SF to scan only for new devices that have been added to the system, and not for devices that have been enabled or disabled, specify the -f option to either of the commands, as shown here:
# vxdctl -f enable # vxdisk -f scandisks
However, a complete scan is initiated if the system configuration has been modified by changes to:
Installed array support libraries.
The list of devices that are excluded from use by VxVM.
DISKS (JBOD), SCSI3, or foreign device definitions.
