Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

By default, this rule suggests a limit of 250 for the number of disks in a disk group.
If one of your disk groups exceeds this figure, you should consider creating a new
disk group. The number of objects that can be configured in a disk group is limited
by the size of the private region which stores configuration information about
every object in the disk group. Each disk in the disk group that has a private region
stores a separate copy of this configuration database.
See “Creating a disk group” on page 200.
Checking disk group configuration copies and logs (vxse_dg2)
To check whether a disk group has too many or too few disk group configuration
copies, and whether a disk group has too many or too few copies of the disk group
log, run rule vxse_dg2.
Checking “on disk config” size (vxse_dg3)
To check whether a disk group has the correct “on disk config” size, run rule
vxse_dg3.
Checking the version number of disk groups (vxse_dg4)
To check the version number of a disk group, run rule vxse_dg4.
For optimum results, your disk groups should have the latest version number that
is supported by the installed version of VxVM.
See “Upgrading a disk group” on page 241.
Checking the number of configuration copies in a disk group
(vxse_dg5)
To find out whether a disk group has only a single VxVM configured disk, run rule
vxse_dg5.
See “Displaying disk group information” on page 198.
Checking for non-imported disk groups (vxse_dg6)
To check for disk groups that are visible to VxVM but not imported, run rule
vxse_dg6.
See “Importing a disk group” on page 204.
