Use Operating System Versions Supported by HPOM
Do not upgrade or downgrade the operating system version of the
management server or managed node to a version not supported by
HPOM. For a list of supported operating system versions on the
management server and on the managed nodes, see the HPOM
Installation Guide for the Management Server.
You can also get a list of supported operating systems by running the
following script on the management server:
/opt/OV/bin/OpC/agtinstall/opcversion
Synchronize System Times
Verify that the system times of the management server and the
managed nodes are synchronized. By synchronizing system times,
you ensure that the time at which the message is generated on the
managed node is earlier than the time at which the message is
received on the management server.
Learn All Root Passwords
Before you install the HPOM agent software, make sure you know all
the root passwords of all the managed nodes.
On UNIX managed nodes, passwords are not required if an .rhosts
entry exists for the root or if the management server is included in
/etc/hosts.equiv (HP-UX 11.x, Solaris).
Work Around Disk Space Limitations
If you do not have enough disk space for HPOM in your UNIX file
system, apply one or both of the following solutions:
• Use a symbolic link.
For example, for Solaris, enter the following:
ln -s /mt1/OV /opt/OV
• Mount a dedicated volume.
Network Path to Management Server
There must be an existing route (network path) to and from the
management server from and to the managed nodes.
