TABLE 1
CR ID Description
6781815 After the ALOM reset or the power cord removal and
insertion, when the server powered on, Solaris OS
startup at the ok prompt of OBP (OpenBoot PROM)
using the boot command may fail.
Error output example:
{0} ok boot
ERROR: All device paths in boot-device
have failed. (*)
{0} ok
It cannot refer to the device paths that configured in
the OBP environmental variable boot-device and
fails to start Solaris OS.
6757066 After downgrading System Firmware 6.6.X or later to
System Firmware 6.3.X or earlier, the showhost
command output displays the firmware information
prior to the downgrade. It has no impact on the
operation, as system is actually working with the
downgraded firmware. Ignore the display.
showhost output example:
sc> showhost

6676561 When Solaris OS is started, BAD TRAP might occur
and the Solaris OS might panic.
Message example:
panic[cpu12]/thread=300044434c0: BAD TRAP:
type=31 rp=2a101c83320 addr=8
mmu_fsr=0 occurred in module "<unknown>" due
to a NULL pointer dereference
Workaround
Note - Fixed in System Firmware 6.7.5 or later.
After the ALOM reset or the power cord removal
and insertion, when you power on the server,
check the OBP environmental variable. Especially,
in case the OBP environmental variable use-
nvramrc? has been set to true, it is necessary in
advance of starting the Solaris OS to see the ok
prompt and check that use-nvramrc? has been
set to true and then execute the boot command.
Confirmation example:
{0} ok printenv use-nvramrc?
use-nvramrc? = true
{0} ok
None.
Note -Fixed in System Firmware 6.6.7 or later.
None.
