Installation and Upgrade Requirements
Before you install or upgrade, you need to check that:
Step 1. The administrator who performs the upgrade has root access and a working knowledge of HP-UX
administration.
Step 2. Sufficient outage time exists for completion of this procedure (which may require several system
reboots)
The following actions need to be performed before starting installation or upgrade:
• See “Check Disk Space” on page 5
• See “Install HP-UX Operating System Patches” on page 9
Check Disk Space
Before installing the VxVM software and related patches, verify that there is sufficient disk space to
contain all of the software. The SD-UX tools check space available and prevent installation if a space
problem is detected.
The following table shows the approximate breakdown of the recommended space requirements for
each file system (assuming the VxVM packages are installed in their default locations.:
Set the PATH and MANPATH Variables
Most of the commands used in the installation are in the /usr/sbin directory or /sbin directory. You
should add these directories to your PATH environment variable, making sure that /usr/sbin precedes
/sbin in the path.
Similarly, set the path of your MANPATH environment variable to include /usr/share/man.
Examples:
If you are using a shell such as sh or ksh, use the following commands:
$ PATH=$PATH:/usr/sbin:/sbin:/opt/VRTS/bin:/etc/vx/bin:\
/usr/lib/vxvm/bin
$ export PATH
$ MANPATH=$MANPATH:/usr/share/man
$ export MANPATH
If you are using a shell such as csh or tcsh, use the following commands:
% setenv PATH $PATH:/usr/sbin:/sbin:/opt/VRTS/bin:/etc/vx/bin:\
/usr/lib/vxvm/bin
% setenv MANPATH $MANPATH:/usr/share/man
