The disks.exclude file is not created by VxVM software installation. To add disk names to this
file, you must create the file. To list a disk in the file, enter only the base device file name. For
example:
c0t0d0
c0t2d0
c1t10d0
To add disks that are in use by LVM volumes to the disks.exclude file, add all disks in the volume
group to which the disk belongs. For example:
# for i in ‘vgdisplay -v uservg | egrep dsk | awk ’{print $3}’‘
> do
> basename $i
> done
NOTE At least one disk must remain in rootdg at all times while VxVM is running.
Excluding Controllers from VxVM Control
The /etc/vx/cntrls.exclude file is used to exclude controllers. When the name of a disk
controller is added to this file, VxVM does not initialize or control all disks on the controller.
The following is an example of the file’s contents:
c1
c3
c8
Excluding Enclosures from VxVM Control
The /etc/vx/enclr.exclude file is used to exclude enclosures. When the name of a disk
enclosure is added to this file, VxVM does not initialize or control all disks on the controller.
The following is an example of the file’s contents:
enc2
enc3
