4873161: Need Support for Soft Poweroff in Solaris x86

Solaris x86 does not currently support power button events generated through ACPI. This means that a poweroff command issued on the system controller (sc> poweroff sn) will not cause an orderly shutdown of the blade’s operating system before powering off the blade.

Workaround

To avoid causing possible corruption to the root disk partition by powering off the disk before the operating system has been shutdown in an orderly fashion, first issue a Solaris command to perform an orderly shutdown (for information about different ways to achieve this, refer to the man pages for the shutdown, halt, and init commands). For example:

#shutdown -i5 -g0

The blade can then be safely powered off from the system controller by means of the sc> poweroff command. For example:

sc> poweroff s2

where the ‘2’ indicates the blade in slot 2 of the chassis.

4856947: drv_usecwait is Not Accurate When CPU Frequency Changes

B100x and B200x blades contain CPU processors that go into a power throttling state when only one power supply unit (PSU) is present in the B1600 chassis. During the early stages of the Solaris boot process a number of software timing loops are calibrated. These are affected when the CPU power throttling state changes: they are not currently re-calibrated upon a change of the power throttling state. This means that, if the power throttling state were to change while the blade was running Solaris x86, the timing loops would no longer execute correctly, and the operation of all device drivers making use of critical timing functions would be affected.

In normal use the power throttling state will only change during removal or insertion of a second PSU.

Workaround

If you have removed a second PSU from the B1600 chassis, or if you have inserted a second PSU into the chassis, you can avoid these two issues by rebooting the blades after the PSU insertion or removal.
