Stuck at the Loading module mptsas screen
So you’re booting vSphere up and you’re stuck at the “Loading module mptsas”
Although this isn’t common, what do you do to get around it?
Here are some possible causes
1. Bad hard drive
2. I/O controller hardware issue
3. I/O controller firmware issue
I faced this issue recently and sure enough, as soon as I took one of the hard drives out, vSphere booted up just fine! I ran a health check scan on the drive and the puppy was sick!
