Is your Dell Drac/idrac default password still calvin?

I’m sure many folk already know this oldie. But you wouldn’t believe how many times I’ve seen a reset config rather than a soft reset of an unresponsive drac being performed using racadm resulting in the default password being reinstated.

Reason for blogging

If you’ve stumbled across this site your are no doubt a fellow techie like myself working within IT infrastructure support and/or consultancy.

My goal is to help share experiences and best practice’s of working in the real world of IT. Along with having a place to keep track of all the random fixes and notes that I have taken over the years. I have tried Evernote, OneNote and the olde classic notepad to try organizing these thoughts but somehow also manage to misplace things.

Anyhow having these notes stored in one place, I have a single pane of glass (How many times have you heard that before lol) to find the information I need as long as I have a connection to the web.

Predominantly I will be posting about how I’ve used products around the Microsoft and VMware stack.
