}

You can now start the definition of the volume group that has its name set by the variable _my_volume_group; the volume group is explicitly defined to be the LVM:

volume_group _my_volume_name

{

#

#Only allow LVM

usage = LVM

You now define some volume group attributes, specifically the maximum number of physical extents (Ignite-UX changes this to suit the disks as required). In addition, you set up the PE size here as well. The default configuration file sets the variable up _hp_root_disk for you.

#

#Setup for defaults allowing of 36 and 72Gb disks as boot disk

max_physical_extents = 2500

(disk[_hp_root_disk].size < 40000MB) { physical_extent_size=8

} else {

physical_extent_size=16

}

#The root disk was found by Ignite-UX for us

#

physical_volume disk[_hp_root_disk]

Now you define the root file system. In all of these file systems, you are not giving them explicit names; this is left up to Ignite-UX. Here, you only set the minimum number of fields for the root file system attributes:

#

 

# Define the root file system

 

#

 

logical_volume

 

{

 

mount_point = "/"

 

usage=VxFS

 

size=400Mb

= true

contiguous_allocation

bad_block_relocate

= false

}

 

Next is primary swap and dump. This configuration does not define a secondary swap. The size is interesting; allocate at least _hp_min_swap as the size. The variable _hp_min_swap again is set by the default configuration file. The maximum size is _hp_pri_swap; however, depending on the available disk space, the actual amount of space allocated is somewhere between _hp_min_swap and _hp_pri_swap.

#

#Define the swap/dump

logical_volume
