The keywords and attributes used for disk configuration are described below:
partitioned_disk
Begins the specification of a disk that may be partitioned into one or two simple partitions. The
disk may be used for file system, swap, or file system and swap. This is also referred to as the
"whole disk" layout.
volume_group group_name
Begins the specification in which one or more disks may be put into Physical Volume Groups, a Logi-
cal Volume Group, and then split up into one or more logical volumes. The group_name must be a
quoted string typically of the form "vgNN" where NN is a two-digit number. However, the name
may be any string representing a valid directory name.
physical_volume group pvgname
Specifies a physical volume group as part of the current volume_group. pvgname must be a
quoted string. All disks listed inside the data structure become a member of the physical volume
group; at least one disk must be a member.
physical_volume disk[hw_path|index|dev_spec
]
Specifies the disk to use for the current configuration. hw_path is the hardware path of the disk (as
reported by ioscan). hw_path may also be a string variable such as the special variable
_hp_root_disk, which corresponds to the disk the user chose from the UI. The
_hp_root_disk variable may also be set in the configuration file, but by default is the hw_path
of the disk with the highest SCSI priority.
hw_path may also be the
* character, in which case all unconfigured disks are included in the
volume_group. In the case of a partitioned_disk, one unconfigured disk is used. Another form of
hw_path may be *= N, where N is the number of disks that should be put in the volume_group.
An alternative to using an explicit hardware path is to use an integer (or integer variable) index
value. If an index value is used, it should be in the range of 0 to num_disks-1.
