Ignite-UX Custom Configuration files

This variabl

e can affect new installations or reinstallations. If you have sized the boot disk of a

system to a certain size and have not included the size of the EFI Partition (and Service Partition,

see "_hp_service_partition_size") you may not have enough disk space to install the

system in the way that you

want.

_hp_service_partition_size

The _hp_service_parition_size integer variable is set by the Ignite-UX GUI and indicates

the size of the HP Service Partition on Itanium®-based systems. This disk partition holds diagnostics

software, saved system and hardware state data, and other utilities used to verify and update

hardware functionality. This value defaults to a size expected by the diagnostics software. A zero

value indicates that no HP Service Partition is to be created. This variable is adjusted to the

minimum HP Service Partition size if set to a non-zero value less than the minimum. This variable is

supported starting with HP-UX 11.23 and only supported on Itanium®-based systems.

This variable defines the size of the HP Service Partition located on bootable disks on Itanium®-

based systems. The minimum size is 400MB (default size 400MB) at this writing. If the size of the

HP Service Partition is set to zero, the partition is not created.

This variable can affect recoveries. For example, if there is no free space left on the boot disk and

an Ignite-UX version is released that increases the size of the HP Service Partition, the recovery or

installation requires manual intervention if the HP Service Partition size minimum is increased

because of lack of disk space

This variable can have an impact on new installations or reinstallations. If you have sized the boot

disk of a system to a certain size and have not included the size of the HP Service Partition (and EFI

Partition, see "_hp_efi_partition_size"), you may not have enough disk space to install the

system in the way that you

want.

_hp_root_grp_disks

The _hp_root_grp_disks integer variable indicates how many disks to put into the root volume

group.

The itool wizard prompts you for the number of disks in the root volume/disk group and whether

they should be striped. However, in the Ignite-UX GUI you must use the Additional button on the

Basic tab to display the # of disks in root VG.

The default configuration described earlier (for B.11.11) sets _hp_root_grp_disks to an enum

from one to the value of the internal variable num_disks. During an installation, Ignite-UX adds

disks automatically to the root volume/disk group to make up this number. Because the disks are

assigned automatically, you must ensure that the disks do not contain data that you do not want to

lose. For example, in a SAN environment those disks may belong to another system.

_hp_root_grp_striped

The _hp_root_grp_striped string variable uses the possible values YES and NO to indicate if

LVM data striping should be used on all disks in the root volume group if multiple disks are in the

root group.

This variable is defined within the default installation configuration so you can easily specify

whether the volumes within the root volume/disk group should be striped across all disks in the root

volume/disk group.
