Hello,

I burned debian-11.0.0-sparc64-NETINST-1.iso  on CdRom for a Sun T2000 (Sun4v)

Used Putty on windows 10 with SerManagement

Boot OK

Startup OK

Partition not OK(?)  : Warnings : Detects 256000 blocks on 65676 blocks ???

Network OK

Download Packages OK

Upgrade with Site mirror Germany OK

But Install the Grub boot Loader

     Unable to install GRUB in /dev/md126p1

   Executing 'grub-install /dev/md126p1' failed

  This is a fatal error.

Used one disk 73Gb  SunFRU : 540-6601-01 Fujitsu Limited

No Raid.

Thanks for your Help.
