TABLE A-5
CR Description
6597761 rm-io followed by multiple set-vcpu
operations might cause the firmware to abort or
ldmd core dump.
During a single delayed reconfiguration
operation, do not attempt to add CPUs to a
domain if any CPUs were previously removed
during the same delayed reconfiguration.

Workaround
Note - Fixed in System Firmware 7.0.9 or later.
Either cancel the existing delayed
reconfiguration first (if possible), or commit it
(by rebooting the target domain), and then apply
the CPU addition.
Failure to heed this restriction can, under certain
circumstances, lead to the firmware returning a
parse error to the LDoms Manager, resulting in
the LDoms Manager aborting. Additionally, if
any VIO devices had been removed during the
same delayed reconfiguration operation, when
the LDoms manager restarts after the abort, it
incorrectly detects the need to perform a
recovery operation. This situation results in a
corrupt configuration, followed by a power
down.
You can also update the System Firmware to the
latest version to avoid encountering this issue in
the future.
