Frequently Asked Questions
Q: Do IPMI Shell commands correspond one-to-one to IPMI commands?
A: IPMI Shell provides only the most useful IPMI commands. It includes a definitive set of commands
that can accomplish the most common management tasks. Therefore, IPMI Shell commands may not
correspond one-to-one to IPMI commands.
Q: Can I manage a system by accessing multiple IPMI instances simultaneously?
A: Yes, you can manage a system by accessing multiple IPMI instances at the same time as long as your
system’s BMC supports more than one concurrent connection.
Q: Can my SOL Proxy server handle multiple connections at a time?
A: Yes, each SOL Proxy server can handle a maximum of 20 SOL Proxy connections simulatenously. By
default only one session is permitted. Edit solproxy.cfg and uncomment and increase the value of
max_session.
Q: How do I unlock an SOL session occupied by another user?
A: Your system’s BMC only supports one SOL session at a time. You must wait for the current user’s
session to time out before you can access a new SOL proxy session. See "Session Timeout" for more
information about configuring the session timeout parameters.
Q: Why can’t I connect to a console using the terminal emulation software included with my Microsoft
Windows
®
operating system?
A: The version of HyperTerminal included with Windows does not provide many functions required
during console redirection. Either upgrade to HyperTerminal Private Edition 6.1 or later, or select any
other terminal emulation software that supports full configuration of VT100 or ANSI emulation mode.
Q. What is the Spanning Tree feature?
A. Most quality routers use the Rapid Spanning Tree Protocol (RSTP) to optimize performance and
remove loops. This can cause delays upto 30 seconds or more whenever a NIC is reset. Resets are known
to happen during BIOS POST, driver initialization, and some network software installation and
configuration. The delay can cause errors when running IPMISH commands. It can also cause a SOL
proxy session to become inactivated. You can configure your router to reduce or eliminate the delay by
enabling the router option edge-port (Dell™ PowerConnect™) or port fast (Cisco). This will allow the
link to remain constant and handle the optimization in real time.
