General requirements
Perform these tasks before you install the NetWorker software on HP-UX.
1. Review the NetWorker Software Compatabilty Guide for the latest information about
supported HP-UX operating systems for each NetWorker installation type.
1. Ensure that the kernel parameter maxfiles_lim is a minimum value of 8192.
2. Set the nfile value, according to the following formula:
The nfile
setting + ( number of expected concurrent save times)
The minimum value for the number of expected concurrent save times is 50.
For example:
nfile = 1 X 50
3. Ensure that the /etc/nsswitch.conf file contains an ipnodes policy:
ipnodes=files
If you do not specify an ipnodes policy, the NetWorker daemons fail to start with a
message similar to the following:
lgtolmd: Failed to resolve the IPv6 localhost address ::1. Please
verify an entry for the IPv6 localhost address exists in your
/etc/hosts file and an "ipnodes" policy has been added to your
/etc/nsswitch.conf file.
Package disk space requirements
Download the NetWorker software package from the EMC Online Support Site and extract
the packages to a temporary location on the target host.
