HP UX System Management Software manual Combining Disks to Form a Single Volume Group

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, Ignite-UX ensures that there is 10 percent free space for each volume and modifies the file system volume size accordingly. If you do not want Ignite-UX to modify the file system volume sizes automatically, add init _hp_ignore_sw_impact=1 to your /var/opt/ ignite/recovery/latest/system_cfg file, or to the

/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"
