EFI and SUN Disk Labels
It's 7:32am and i'm on a customer site with a tight deadline installing a new system to run an test rig for a new NetWorker server; Bugger to find that the jumpstart fails to install, and it's that gotcha for me everytime, as I didn't change the label on the new disks.
You can't install Solaris on an EFI disk
This is a mental note for me to remember how to change the label.
There is a good document on docs.sun.com which shows some of the differences between the two formats but suffice to say that you cant install Solaris on an EFI disk. In a nutshell, you need to change it to an SMI label.
Easily done by simply using 'format -e'. select the label option, and then SMI label.
Once you have done that you can check the partition table as normal and restart the install successfully
