HP-UX 11i Version 1 Installation and Update Guide, June 2004

Choosing a Migration Path: Cold Install or Update
Deciding Which Method to Use
Chapter 234
If any of these patches appear in standard output, you have the patch
installed and need to install the latest version of Update-UX before
starting the update process.
See “Step 1: Install the update-ux Command (Required Task!)” on
page 118 describes the steps required to install the latest version of
Update-UX.
VxVM Rootability Not Enabled with update-ux
With the September 2002 release of HP-UX 11i v1, you can not enable
VxVM rootability through the update process using update-ux. If you
wish to manage your root volume with VxVM, you can choose to either
enable rootability by:
• cold-installing HP-UX 11i v1, see “Using VxVM Rootability” on
page 36
• using the VxVM conversion tools provided in the Base-VXVM and
FEATURE11-11 bundles that are installed with HP-UX 11i v1 (for
more information about HP-UX 11i v1 software bundles, see “What is
Installed with HP-UX 11i v1?” on page 70). For more information, see
the VERITAS Volume Manager 3.5 Release Notes and VERITAS
Volume Manager 3.5 Administrator’s Guide on the Instant
Information CD
Updating to 64-bit OS
update-ux defaults to the OS word-width that your system is currently
running. For example, if the target system is running 32-bit OS, this will
be the default for the new OS to be installed.
NOTE Changing an existing 64-bit OS to 32-bit is not supported. To return a
64-bit OS to 32-bit, use the Ignite-UX make_tape_recovery or
make_net_recovery command to restore the 32-bit OS.
You can update a system from 32-bit OS to 64-bit OS while updating to
HP-UX 11i v1, provided that you consider these hardware and firmware
issues:
• Is your system capable of running 64-bit operation? See Table 3-1,
“Supported Systems,” on page 46 in Chapter 3.
