Have you ever wanted to run linux like top command and see most active luns on your NetApp filers?
Even if this twisted idea never crossed your mind, this is one of the usefull tools to keep your eye on when managing NetApp filer(s).
The Lun Top tool is a client-based utility that scans a filer via rsh/ssh and ranks the LUNs by usage. It enables the user to identify LUNs with the most activity on a given filer. There are two versions available: a Perl script for UNIX and an executable file for Windows. (more…)

Project Purpose:
CURRENT STATUS: VmWare site changes detected, adjusting the script to work with latest changes, please check back later
ESX Updater 3.x project has been created to simplify the patch management of ESX 3.x hosts. It connects to vmware site, downloads and installs various update packages you choose. It is intelligent enough to autodetect ESX version you are running, checks for internet connectivity and root permissions. Moreover, script lets user choose which packages can be installed (critical, general, security or all).
Written in bash, script should run on ESX 3.x host. Please note, if ESX host is in active state - serving VMs, prior to update, all VMs must be either VMontion(ed) to another ESX host or shutdown. Since ESX 3.x comes stripped of all essential utilities, this script comes bundled with GNU wget utility from RHEL3 that will work on VmWare ESX 3.x.

ESX Updater 3.x project has been created to simplify the patch management of ESX 3.x hosts. It connects to vmware site and downloads various update packages you choose (critical, general, security or all). It creates tar.gz file with install script. Written in bash, it must be run on non-esx, preferably Linux host, to create tar.gz installer. Script must be ran on Linux with general GNU utilities (sed, awk, wc, wget, tar, gz and perl) host connected to the internet.
Script Type: Repository Server Edition -> this script must be run on Linux non ESX host.If you ESX host has internet connectivity, I highly recommend using this script.
Supported OS:
ESX 3.0.0 and ESX 3.0.1 (more…)
