HP-UX 11i v3 Installation and Update Guide, March 2011 (Edition 9.2)

NOTE: A license for the HP Insight Dynamics - VSE suite for Integrity is installed by default with
the VSE-OE and DC-OE. To use this license, it must be activated from the Central Management
Server (CMS). These OEs also include the optional VSEMgmt package, which installs the CMS
software for Insight Dynamics. Before installing the CMS software, review the following documents,
available at http://www.hp.com/go/insightdynamics/docs.
• HP Insight Dynamics 6.2 Integrity CMS Installation and Configuration Guide
• HP Insight Software 6.2 Support Matrix
• HP Insight Dynamics 6.2 Release Notes
• HP Insight Dynamics 6.2 Getting Started Guide
NOTE:
Also of particular note is the documentation for configuring HP Serviceguard with Bastille and
IPFilter. If you have used Bastille to harden your system at installation or update, and you are a
Serviceguard user, see HP-UX System Administrator's Guide: Security Management (http://hp.com/
go/hpux-core-docs).
Migrating to the agile mass storage stack
The new mass storage stack for HP-UX 11i v3 is intended to supersede the existing mass storage
stack. However, in HP-UX 11i v3 both legacy and persistent DSFs can exist in parallel. Existing
legacy DSFs will continue to work as before; they are completely backward compatible, and will
not be affected by any persistent DSFs on the same server. (The agile mass storage stack, as well
as legacy and persistent DSFs, are discussed in “Next generation mass storage stack” (page 29).)
You may choose to migrate to the new agile mass storage stack or you can continue to use the
legacy mass storage stack. However, if you want to use the new features of the agile mass storage
stack and are not affected by existing limitations, you should consider migrating to the new mass
storage stack.
For more information on the new mass storage stack and to migrate from the legacy view to the
agile view, see the white papers “The Next Generation Mass Storage Stack: HP-UX 11i v3” and
“HP-UX 11i v3 Persistent DSF Migration Guide” (http://hp.com/go/hpux-core-docs).
System tuning for VxFS 4.1
If your system has the minimum amount of memory, you might need to manually set VxFS tunables
for optimal performance after cold-installing or updating to HP-UX 11i v3. Two VxFS tunables,
vx_ninode and vxfs_bc_bufhwm, have an effect on system memory consumption. For guidelines
on setting them for machines with relatively low RAM, see the Veritas File System 4.1 Administrator's
Guide at http://hp.com/go/hpux-core-docs.
Backing up the system
Now that you have a solid system configuration, you need to back it up. This provides you with a
stable configuration that you can use to rebuild the system, if necessary.
For more information, see “Backing up your system” (page 21).
Uninstalling HP-UX 11i v3
If you cannot resolve problems after installing HP-UX 11i v3, then you might want to uninstall it.
The process depends upon the install process you followed:
• If you previously created an operating system recovery image with either
make_net_recovery or make_tape_recovery using Ignite-UX, boot the system from that
media to return the OS and any archived applications to the previous release. See the Ignite-UX
