To reserve a disk
◆
Type the following command:
# vxedit [-g diskgroup] set reserve=on diskname
After you enter this command, the vxassist program does not allocate space
from the selected disk unless that disk is specifically mentioned on the
vxassist command line. For example, if mydg03 is reserved, use the following
command:
# vxassist [-g diskgroup] make vol03 20m mydg03
The vxassist command overrides the reservation and creates a 20 megabyte
volume on mydg03. However, this command does not use mydg03, even if
there is no free space on any other disk:
# vxassist -g mydg make vol04 20m
To turn off reservation of a disk
◆
Type the following command:
# vxedit [-g diskgroup] set reserve=off diskname
See the vxedit(1M) manual page.
Displaying disk information
Before you use a disk, you need to know if it has been initialized and placed under
VxVM control. You also need to know if the disk is part of a disk group, because
you cannot create volumes on a disk that is not part of a disk group. The vxdisk
list command displays device names for all recognized disks, the disk names,
the disk group names associated with each disk, and the status of each disk.
