Before You Install

System Requirements

For HP-UX 10.20, Series 700 Software Disk Striping arrays are not

supported. SDS arrays can be converted to LVM via the utility

sdstolvm. If you upgrade to HP-UX 10.20, as opposed to installing it,

this conversion will be done for you automatically during the upgrade.

LVM disk striping can be set up on some volumes during the installation.

However, striped volumes cannot be mirrored later on. Note that not all

types of volumes may striped. This is due to an unbalanced amount of

disk space assigned to the root/boot/swap volumes on the root disk that

must not be striped.

Networking Requirements

Networking capabilities are not mandatory for a 10.20 cold install unless

you are loading your OS and applications from a remote system. If you

are loading from a remote system, you will need the following (for the

Ethernet™ interface):

• A network card. If your system has multiple LAN cards, select the

card that is conﬁgured onto the correct network during the install

process. Only one card can be conﬁgured for install. All other cards

will not be conﬁgured and cannot be used during the installation.

• A network install server. This must be on the same network subnet as

the system that will be booted. This may require having one server on

each subnet from which to boot clients.

• A functional network connection. If you have more than one LAN

connection, be prepared to select the correct one with which to

connect to the install server system.

Note: You cannot cold install via the network from a non-Ethernet

interface.
