IMPORTANT: The
-n
option with the
xtcli disable
command must be used carefully because this
may create invalid system state configurations.
The state of
empty
components does not change when using the
xtcli enable
command, unless the force
option (
-f
) is used.
The state of
off
means that a component is present on the system. If the component is a dANC controller, node,
or ASIC, then this will also mean that the component is powered off. If the administrator disables a component,
the state shown becomes
disabled
. When the
xtcli enable
command is used to enable that component for
use once again, its state switches from
disabled
to
off
. In the same manner, enabling an empty component
means that its state switches from
empty
to
off
.
On a running/routed system, dANCs that were not enabled when the network was brought up should not be
enabled with the
xtcli enable
command, as they will not be routed into the Aries High Speed Network (HSN).
Instead they should be added to the HSN with the
--add
option of the
xtwarmswap
command. This will
automatically enable the blade when it is successfully routed into the system.
For more information, see the
xtcli(8)
man page.
3.4.11 Set Hardware Components to
EMPTY
Use the
xtcli set_empty
command to set a selected component to the
EMPTY
state. HSS managers and the
xtcli
command ignore empty or disabled components.
Setting a selected component to the
EMPTY
state is typically done when a component, usually a blade, is
physically removed. By setting it to
EMPTY
, the system ignores it and routes around it.
Only blades that are not currently routed into the HSN (i.e. removed with the
xtwarmswap
command) should be
set to empty while the system is running, and only if the plan is to then physically remove the dANC from the
system, otherwise the
xtcli disable
command should be used.
IMPORTANT: The
-n
option with the
xtcli disable
command must be used carefully because this
may create invalid system state configurations.
For more information, see the
xtcli(8)
man page.

3.4.12 Stop Components Using the Hardware Supervisory System (HSS)
WARNING: Power down the rack(s) with software commands. Tripping the circuit breakers may result in
damage to system components and to the file systems, and has an effect similar to that of abruptly
powering-off any Unix system.
WARNING: Before powering down a Dual Aries Network Card (dANC) or a rack, ensure the operating
system is not running on any nodes associated with dANCs.
The
xtcli power down
command powers down the specified rack and/or dANCs within the specified partition,
chassis, or list of dANCs. Racks must be in the
READY
state to receive power commands. The
