When to Update
You can update rather than cold-install HP-UX 11i v1 when:
• You are updating from a supported HP-UX 10.20, HP-UX 11.0, and
HP-UX 11i v1 system. See “Supported Update Paths to HP-UX 11i
v1” on page 51 for specific details.
• You are concerned about recovering unique applications and data on
your root volume, and do not want to write over non-OS files, which
occurs when cold-installing HP-UX 11i v1.
• Each system has a unique configuration.
• Current disk space is sufficient for HP-UX 11i v1. See “How to Plan
Your Disk Space Needs” on page 33.
IMPORTANT If /stand is not of sufficient size, the partition can be resized,
requiring the root disk to be reformatted. In this case, you must
cold-install rather than update your system. To determine whether
/stand is large enough to support this release of HP-UX 11i v1, see
“Disk Space Requirements for a Cold-Install” on page 34.
This installation method uses the update-ux command and Software
Distributor (SD) tools to selectively overwrite the operating system and
application software from media or a network source depot. An
advantage of performing an update is that it leaves user data,
configuration, and applications in place. Updating to HP-UX 11i v1 is
limited to the supported paths listed in “Supported Update Paths to
HP-UX 11i v1” on page 51.
See Chapter 4, “Preparing to Install or Update to HP-UX 11i v1,” on
page 63 for details on how to prepare your system to update to HP-UX
11i v1. The update process is described in Chapter 6, “Updating to
HP-UX 11i v1,” on page 91.
