Here are the volume manager disk layouts. The definition of logical volumes and volumes are
performed identically with Ignite-UX. The usage definition (LVM or VxVM), not the volume group
definition, determines if LVM or VxVM will be used.
_hp_disk_layout == "VERITAS Volume Manager (VxVM) with VxFS" |
_hp_disk_layout == "Logical Volume Manager (LVM) with HFS" |
_hp_disk_layout == "Logical Volume Manager (LVM) with VxFS"
{
Here you are defining the variable _hp_group_name. However, you must first make sure it is not
visible on the Additional button (since you do not want anyone to be able to change it). If the
value of _hp_disk_layout is set to be VxVM ("VERITAS Volume Manager (VxVM) with VxFS"),
set _hp_group_name to be rootdg; otherwise it is LVM you are using, and vg00 is the name
you are going to use
49
.
The _hp_group_name does not actually do anything except hold the initial name of the volume
group or disk group this configuration is defining. If this variable could be changed using the
Additional button, it would not do anything since it is only a temporary variable to hold the
name
50
.
_hp_group_name visible_if FALSE
(_hp_disk_layout == "VERITAS Volume Manager (VxVM) with VxFS") {
_hp_group_name = "rootdg"
} else {
_hp_group_name = "vg00"
}
Here is the definition of a root volume or disk group. The construct in the disk[] keyword
*=_hp_root_grp_disks means the first _hp_root_grp_disks disks. Since the value of
_hp_root_disk is always disk[1], we know _hp_root_disk will be one of the disks
defined in this volume group, and there may be _hp_root_grp_disks-1 additional disks.
Depending if VxVM was chosen as the volume manager, we then choose either LVM or VxVM as
the volume manager via the usage keyword. That is followed by some housekeeping configuration
to maintain good values for the number of extents in a volume group and the extent size (only
applies to LVM).
The temporary variable is necessary to give the volume group a name. You do this by assigning
the name to a temporary variable, and then starting your volume group definition with that name.

VxVM 3.5 and earlier requires the root volume group be named rootdg. This is enforced by Ignite-UX.

To change the name of a volume group you use the Ignite-UX GUI to select the File system tab then the Additional
Tasks button, and click Group Parameters. From the Group Parameters dialog box, select the name of the group to
change from the selection list, change the group name, press modify, and then click Ok.
