The power off command powers off the partition in which this particular
SRM console is running. When issued in this form, the command halts all
activity of the QBB – all drivers, interrupts, global port transactions, etc. -
before power is removed from the QBB logic. PCIs attached to a
partition powered off in such a manner remain powered.
The partition is identified and the QBBs within it enumerated.
Each QBB in the partition is powered off.
Information messages identify the PSMs in each QBB and notes they are
powered off.
Information messages identify the link to the H-switch in each QBB and
notes that the links are off.
