Configuring Newly Added Disk Devices
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 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 run ioscan followed by insf to
make the operating system recognize the new disks, and then invoke the
vxdctl enable command. See the vxdctl(1M) manual page for more
information.
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. See the vxdisk(1M) manual page for more
information.
Discovering Disks and Dynamically Adding Disk
Arrays
You can dynamically add support for a new type of disk array which has
been developed by a third-party vendor. The support comes in the form of
vendor supplied libraries, and is added to command.
Adding Support for a New Disk Array
The following example illustrates how to add support for a new disk
array named vrtsda to system using a vendor-supplied package on a
mounted CD-ROM:
# swinstall -s /cdrom vrtsda
The new disk array does not need to be already connected to the system
when the package is installed. If any of the disks in the new disk array
are subsequently connected, and if vxconfigd is running, vxconfigd
immediately invokes the Device Discovery function and includes the new
disks in the VxVM device list.
Device Discovery Function
To have VxVM discover a new disk array, use the following command:
# vxdctl enable
