Symptoms

smconfigtest is an IB switch command used to verify OpenSM configurations in /etc/opensm/opensm.conf.

smconfigtest reports errors when it detects invalid configuration in /etc/opensm/opensm.conf or when /etc/opensm/opensm.conf has been manually edited, for example via the vi command.

Oracle strictly does not recommend customers to manually edit /etc/opensm/opensm.conf at all.  The recommended way to adjust OpenSM settings is only via IB switch commands (see below).

However, /etc/opensm/opensm.conf, being a file and just like any other files, can be manually edited by any privileged user, such as the root-user, either wittingly or unwittingly; accidents or typos can occur.

An example of setting log_max_size to 8 yields:
