#vxdiskadm

Typing vxdiskadm brings up a menu based utility (text) . The options , their explanation and screen shots
are given below .Most of the options need a disk name , device name or disk group name and you can have this information by typing list in the vxdiskadm menu .The list menu option is used to display a list of disks attached to your system. This also lists removed or failed disks. Most useful to get a quick view of all disks or list details of a single disk – its name , volume association and status.

A disk needs to be formatted in order to be included in volume manager . volume manager will report unformatted disk as invalid and a will only recognize after formatting

By default all the available disks in the system are considered for inclusion as volume manager disk however to exclude certain disks, list the names of the disks to be excluded in the file /etc/vx/disks.exclude before the initialization or encapsulation. Similarly, you can exclude all disks on specific controllers from initialization or encapsulation by listing those controllers in the file /etc/vx/cntrls.exclude.

? & ?? options provide help about the menu item and menu system.
