Its not unheard of that an HP ILO (Integrated Lights Out) can become sick and slow down to a crawl. When this occurs, a restart of the ILO is in order, which is easily accomplished via the ILO cli interface. Note that you need to make sure that that you have enabled ssh access in ilo.

The HP Systems management homepage is a web based utility for managing and monitoring Proliant Servers. It can be installed via the ProLiant Support Pack DVD (on linux its just an rpm). Once installed you can modify the default settings via the perl script, hpSMHSetup.pl located in /usr/local/hp.
To access your server's homepage navigate to https://<yourhostname>:2381 in your browser. You must include the https:// part of the url. Use your root user and password to access.
From the homepage you can monitor system, subsystems and status views of your server. Any critical, major, minor, or warning alerts will appear in the Overall Status Summary.
