# Appendix A - IPMI Checks
[**Software Installation Guide Table of Contents**](ig_TOC.md)
Procedures provided in this appendix can be used to establish a level of
confidence that your IPMI implementation is functional. Note that IPMI
implementations can be problematic, and while these procedures can
provide a level of confidence, absolute assurance that
your particular IPMI implementation will operate error-free is not
possible.
## IPMI Platform Check
Perform the following steps:
1. Identify the BMC model number on all servers.
1. Identify the BMC firmware revision on all servers.
1. Ensure that the BMC model number and firmware revision are the same
on all servers.
1. Using the `fence\_ipmilan` utility provided by the fence-agents RPM on
Red Hat/CentOS, verify that the following commands complete
successfully:
a. `fence_ipmilan -a -l -p -o monitor`
b. `fence_ipmilan -a -l -p -o status`
c. `fence_ipmilan -a -l -p -o reboot`
d. `fence_ipmilan -a -l -p -o off`
e. `fence_ipmilan -a -l -p -o on`
This process could run some combination of these commands over an
extended period (e.g., monitor every 30 seconds or so with periodic
power commands), for each BMC.
