considerations
and workarounds
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 48 in Chapter 3.
• Is your system’s firmware recent enough to support 64-bit operation?
See “Firmware Requirements” on page 53 in Chapter 3.
• 64-bit binary data cannot be used by 32-bit applications. 64-bit is
useful if you need large address space, such as for use with very large
databases and large-scale modeling. 64-bit applications can be
compiled and linked on 32-bit systems; however, these applications
cannot be run on a 32-bit system.
• If updating an existing HP-UX 11i v1 system from 32-bit to 64-bit
OS, do not include the HP-UX 11i v1 Quality Pack (GOLDQPK11i)
bundle in the update-ux command. Doing so may cause a mk_kernel
failure. Instead, install the GOLDQPK11i bundle from the Support
Plus CD using swinstall after updating to this release.
• If updating an HP-UX 10.20 system with the CDE Spanish language
keyboard enabled: After updating from HP-UX 10.20 to HP-UX 11i
v1, changing from 32-bit to 64-bit OS and installing the HP-UX 11i
v1 Quality Pack (GOLDQPK11i) bundle, you must install patch
PHSS_23644 (or superceding patch PHSS_23818) from the
GOLDBASE11i quality pack bundles on the latest Support Plus CD
to re-enable the CDE Spanish language keyboard. Obtain this patch
from the HP IT Resource Center (http://itrc.hp.com). This
problem does not occur with other languages.
• If updating an existing HP-UX 11i v1 system having any of the
following EISA network drivers installed, you must remove all EISA
drivers before updating from 32-bit to 64-bit OS:
— 100BaseT-00 — EISA 100BaseT
— FDDI-03 — EISA FDDI
— TermIO-01 — EISA MUX
— TokenRing-02 — EISA Token Ring
(New drivers installed by default are listed in “HP-UX 11i v1
Always-Installed Network Drivers” on page 82. Other drivers can be
specified in the update-ux command or installed later using
swinstall.)
