iLO
HP iLO, or integrated Lights Out, is a feature on HP servers that allows users to access the machine over the network even if the OS on the server cannot be reached.
A server's iLO can be reached in two ways:
- Via
ssh, throughssh server-ilo-hostname - Via a web interface by visiting
https:\\server-ilo-hostname.csl.tjhsst.eduwhile using a VPN
The version of iLO firmware that the servers ship with does not support access to the OS. The firmware can be updated with through the following steps:
- Unzip the executable with
unzipor a similar command - Retrieve the
.binfile from the unzipped executable - Access the iLO server you wish to update via the web interface
- Go to
Firmware and OS Software>Update Firmware - Select
Local fileand the.binfile you extracted earlier - Select
Flash, this will update the firmware
Flashing the iLO firmware will reboot the iLO, but will NOT reboot the server.
HP has small password length password limits on iLOs. For HP iLO 5 (as of firmware version 1.35), it accepts any length password for a reset but only stores the first 39 characters (so you have to use the first 39 to login). HP ilO 2 has a similar problem, but with a 20 character limitation.
