The vxdiskconfig utility scans and configures new disk devices attached to the host, disk devices that become online, or fibre channel devices that are zoned to host bus adapters connected to this host. The command calls platform specific interfaces to configure new disk devices and brings them under control of the operating system. It scans for disks that were added since SF's configuration daemon was last started. These disks are then dynamically configured and recognized by SF.
vxdiskconfig should be used whenever disks are physically connected to the host or when fibre channel devices are zoned to the host.
vxdiskconfig calls vxdctl enable to rebuild volume device node directories and update the DMP internal database to reflect the new state of the system.
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.
