become available again. The I/O processors and I/O adapters to which these
disk units are attached may only be replaced while the domain is powered off.
Any other actions on these hardware resources are unsupported and may cause
failures requiring a system IPL to recover. There are no restrictions on the service
actions that can be performed on other hardware resources in the power
domain.
v A power domain containing hardware resources that are in use by the operating
system cannot be powered off. All configuration objects using hardware
resources in the power domain must be varied off before the power domain can
be powered off.
v You must end all active CRGs (cluster resource groups) prior to attempting to
power off a power domain using concurrent maintenance.
v The system you are using must be the SPCN (system power control network) for
the selected power domain.
v A power domain containing switchable bus adapters cannot be powered off if
any of the bus adapters are owned by a system other than the one you are
using.
You can find more information on these restrictions by pressing F1 at the
Concurrent Maintenance display.
