Yes, GPT is supported on SPARC T4 and newer only.

Normally, when you use automatic partioning, the installer should detect
whether your machine supports GPT and if not, use a Sun-based partition
layout.

Unrecognized magic number in media label

2020-10-28 Thread Dennis Clarke


I was just testing the installer image at :

https://cdimage.debian.org/cdimage/ports/snapshots/2020-10-13/

Everything seems to just work fine. Until reboot wherein I see :

Boot device: /pci@1f,0/pci@1,1/scsi@2/disk@0,0:a  File and args:
Unrecognized magic number in media label
Can't open disk label package
Evaluating: boot

Can't open boot device

ok

I am guessing that my mistake was to use a gpt label on the boot disk
and the old firmware on this test Netra machine can only grok a sun
label. Just a guess. Let me know if this seems reasonable.
