HP-UX 11i v3 Installation and Update Guide, September 2009 (Update 5 Release)

NOTE: Once you have updated from 11iv2 to 11iv3 on the active system image, you
can go back and forth between the inactive 11iv2 image and the updated 11iv3 image
by ensuring the following:
• That you have manually installed Dynamic Root Disk (DRD) version A.3.1.0.1027
or later onto your updated HP-UX 11i v3 system image if you updated to HP-UX
11i v3 update 1 (September 2007) or update 2 (March 2008). Due to a packaging
problem that has now been fixed, the 11i v2 version of DRD does not get
automatically updated on the 11i v3 system.
• That you do not use the drd runcmd operation when an HP-UX 11i v2 system is
booted, and HP-UX 11i v3 is installed on the inactive image. Use of this operation
would invoke 11i v3 libraries and executables, which can make system calls not
supported on the 11i v2 kernel.
The drd clone contains all files and directories in the root volume, and thus has all the
components that are essential to bringing up a functional system.
In addition to system recovery, DRD has other uses, all of which can reduce downtime.
These include system maintenance, patching, testing, and provisioning. See “Reducing
downtime using Dynamic Root Disk” (page 36) for more information, including links
to documentation and a website.
Part II: Backing up your data files
Depending on your system backup needs and your configuration, there are a number
of different backup methods from which to choose. Two possible backup methods are
as follows:
• HP Data Protector
• HP-UX fbackup/frecover utilities
Choosing HP Data Protector for backup
If you are backing up large numbers of systems, the HP Data Protector software product
can be particularly useful. HP Data Protector is faster than other backup methods and
provides for unattended backup as well. It allows you to efficiently centralize and
administer backup procedures.
Using HP Data Protector involves setting up a database server and running software
that directs and records the backup process for clients. For more information, see the
HP Data Protector website (http://hp.com/go/dataprotector).
Choosing HP-UX fbackup/frecover utilities
Use the fbackup and frecover commands to selectively back up and recover files.
The fbackup command can do the following:
