VMware ESX – EMC Clariion Host Grab utility

With an ESX host connected to a Clariion, there may be a time where you are experiencing connectivity issues.  One of the first things you can do before you contact EMC support is to run the EMC Host Grab utility.

This utility will connect to your ESX host, and also the array. It will gather all the details it will need and will produce a zip file that can be uploaded to EMC Powerlink.

The EMC Primus article is “emc102335”.

VMware KB: Troubleshooting ESX virtual machine performance issues

This article gives some basic guidance on how to isolate a performance issue on ESX. Bad performance can be caused by several different areas: CPU constraints, memory overcommitment, storage latency, or network latency. If one or more of your virtual machines has a bad response time, consider each of these areas to find the bottleneck.
