Listing Disk Devices in SAM
To list disk devices in SAM, from the Disks and File Systems SAM area, select Disk
Devices. The Disk Devices screen lists the system’s disk devices. When VxVM is installed
on the system, SAM includes a “Use” column to indicate whether a disk is under LVM or
VxVM control, or whether it is unused.
If a VxVM disk is online and part of a disk group, the disk group name is listed under the
“Volume Group” column. If a VxVM disk is initialized, but not yet part of a disk group, it
is listed under the “Volume Group” column.
The following figure shows a Disk Devices screen for a system with three VxVM disks,
one LVM disk, and a CD device. One of the VxVM disks is part of the rootdg disk group.
The second disk is part of the maroon disk group. the third disk, which is listed under the
“Volume Group” column, is not yet part of a disk group.
Listing Volume Groups and Disk Groups in SAM

screen for the same example system. vg00 is an LVM volume group with eight logical
volumes; rootdg and maroonareVxVM diskgroups,with one volumeeach. See thefigure
