Combining Disks to Form a Single Volume Group
You can put two disks together to form a single volume group. Two file systems are defined; both are striped across both disks. The following example illustrates this concept:
volume_group "appsvol" { usage=LVM
physical_volume disk[2/0/1.5.0] {
}
physical_volume disk[2/0/1.4.0] {
}
logical_volume "apps1" { mount_point = "/apps1" usage = VxFS size=30% free minfree = 5
stripes = 2
}
logical_volume "apps2" { mount_point = "/apps2" usage = VxFS
size = remaining minfree = 5 stripes = 2
}
}
The preceding example uses LVM as the volume manager. However, it is also applicable to VxVM if usage=LVM is changed to usage=VxVM.
The first file system, /apps1, is sized by calculating the amount of space required by the software that is to be installed, and then adding 30 percent for free space. The second file system, /apps2, uses the remaining space on the disks.
NOTE: You can modify the file system volume sizes in the recovery image when the image is installed. By default,
/var/opt/ignite/clients/client/recovery/latest/system_cfg file.
Defining Networking Parameters
The following example lines define a few of the network parameters that are assigned to the system after it has been installed:
final system_name = "acorn1"
final ip_addr["lan0"] = "10.99.45.123" final netmask["lan0"] = "255.255.255.0" final nis_domain = "nis1"
final route_gateway[0] = "10.99.45.1"
