Setting network options for IBM Storage Protect on AIX systems

The default values for network options on the IBM® AIX® operating system can be used for most IBM Storage Protect configurations. Review the preferred network-related settings.

Procedure

  • If you use 10 Gbit Ethernet adapters, enable flow control on the switch or router port that the AIX system is connected to. For instructions about enabling flow control, consult your network administrator or see the manuals for your router or switch.
  • Set the rfc1323 network option to 1. To ensure that the new setting is used whenever the system is restarted, use the -p option on the command.
    For example, issue the following command:
    no -o rfc1323=1 -p
  • If you see nonzero values for the no mbuf errors field in the output from the entstat, fddistat, or atmstat commands, increase the value for the thewall option. Set the thewall option to at least 131072 and the sb_max option to at least 1310720.
    Some versions of the AIX operating system have larger default values for these options, so that modifying the values might not be necessary.
