64 bit mode on on E450 and Sol8
argoth
solaris 8 (and 7) will default to using a 64-bit kernel if the platform
is capable of it (unless processors are less than 200MHz, see
/platform/sun4u/boot.conf). the e450 machine is sun4u using sparcv9
processors, which dont support the latter case, so it should default to a
64-bit kernel.
my little troubleshooting method;
if 64-bit support was installed; check OBP boot-file variable
if "data not available" or "kernel/sparcv9/unix"; check OBP diag-switch?
variable
if true; set to "false" OR check diag-file variable
if "data not available" or "kernel/sparcv9/unix"; i'm lost
kernel/sparcv9/unix # 64-bit
kernel/unix # 32-bit
use pkginfo to find if 64-bit support is installed
boot-file controls what kernel to boot
diag-switch? tells whether the system should enter diagnostic mode
diag-file tells the system which kernel to boot in diagnostic mode
use eeprom (from command line) or printenv/setenv (from OBP) to determine
boot-file/diag-file/diag-switch?
take care

news:3A9BE8F1...@berbee.com...
I just installed Solaris 8 on an E450. After I installed and configured
DiskSuite to do mirroring on all drives (including / and /usr), when the
machine boots up, it boots in 32 bit mode, (a isainfo -kv returns 32 bit
kernel modules)
As far as I know, after the initial installation, it was running the 64 bit
kernel. It was after I rebooted for DiskSuite, that I noticed it was running
in 32 bit mode. Could something in DiskSuite have changed this?
I installed the core configuration (and indicated I wanted the 64 bit
support), and added a few packages after that.
How do I get running in 64 bit mode again?
Thanks,
Gary

Look in the Solaris 8 Sun Hardware Platform Guide which is in
the box with the CDs.
There is a whole chapter devoted to updating the firmware of
various machines, including early E450s.
Follow the instructions BEFORE installing Solaris.
When all else fails - read the instructions. <B-).
