How to start HP Insight Diagnostics

Using HP Offline Insight Diagnostics using the SmartStart CD

Click on http://h18023.www1.hp.com/support/files/server/us/download/24733.html

Download the file to a temporary directory and extract the ISO image to that directory. To create a CD from this ISO image, you must use a software utility capable of writing an ISO file to a recordable media such as CD-R.

Note: Simply copying the ISO file to a CD-R will NOT result in a usable CD.

Then boot off the server using the SmartStart CD and then Click On Maintain Server
Then click on Diagnose Server
The Insight Diagnostics Window Opens Up
Change the 'view level' from the default 'Overview' to 'Advanced'.
Under 'categories' drop down box, select 'All'
Save the file as default on a floppy disk

Recently, i have encountered a few of the BL25p blades that cant even boot up. Then we won't be able to use this tool at all.

Do beware that HP support may insist that you patch, the firmwares, iLO, etc, which i think is a waste of time. Insist on a on-site engineer if you have the contract else likely its hardware issue. In my case, was a faulty mainboard.
