Opening firewall ports for iLO

If you want to access an iLO behind a firewall, there are some TCP ports that need to be opened on the firewall to allow all iLO traffic to flow through.  Here is a list of the default ports used by iLO, but these can be modified on iLO’s Administration… Access… Services… tab.

How to Kill iLO 2 Remote VSP Connections

A new feature crept in unannounced in the recent iLO 2 v1.77 firmware update from HP: You can now kill / terminate Virtual Serial Port (VSP) sessions that are open or hung. This is a very useful when you need to connect to the VSP but you (or someone else) is already connected from another [...]

Interpreting (decoding) NMI sources from IML log messages

If you are using the HP health drivers for ProLiant servers (or at least the hp-wdt driver), any system hangs or panics caused by NMI’s (non-maskable interrupts) will be logged to the IML (Integrated Management Log) and can be viewed using iLO. The IML log is on the System Status page of the iLO web [...]

HP is rebranding iLO as the ProLiant Onboard Administrator

You may have noticed something different in HP’s latest ProLiant G6 server announcements. Something called the HP ProLiant Onboard Administrator that doesn’t have anything to do with blades! For example, this page from HP.COM: HP ProLiant Onboard Administrator

Update iLO firmware en masse with BladeSystem Onboard Administrator (OA)

This OA command I recently came across works like magic. If you’ve ever done it manually, you know how time consuming it can be to update the iLO (Integrated Lights Out) firmware across multiple ProLiant servers. However, with the BladeSystem Onboard Administrator, it can be accomplished in seconds using a single CLI command to update [...]

How to find all the iLO’s on your network

Have you ever forgotten an IP address for an iLO on your network? Do you ever wonder “What’s my iLO IP Address?” Maybe you’re using DHCP, and you’ve added a new server to your network, but you don’t know the IP address of its iLO (and you’re not using dynamic dns – so the iLO [...]

Setting iLO Configuration using the Onboard Administrator

Haven’t you always wanted to configure your blade iLO’s en masse instead of one by one? You can now with the Onboard Administrator’s ‘HPONCFG’ command. Here’s an example of a RIBCL XML script that can be used with the HPONCFG command in the Onboard Administrator (OA) command line interface (CLI). This example script will modify [...]

Using conserver to monitor iLO virtual serial ports (updated)

There are a lot of companies that use serial console servers (e.g. Cyclades) to monitor the serial ports of their servers. These servers are usually running an operating system like Linux or FreeBSD. By accessing the serial console, the administrator can control almost everything on the server, and even watch it boot. This type of [...]
