If alerts are discovered and cleared, wait a few seconds and execute the
xtcli -t l0 s0
command again
to ensure the alerts did not return. If they do return, contact Cray Support. If the errors do not return, the
underlying transient problem can be ignored.

4. Power up the Aries Network Card Controllers (ANCCs) by executing the following command:
root@smw:~
xtcli power up s0
5. Verify that the dANCs are in the '
ready
' state. Also ensure that
alert
or
reserved
is not displayed in the
Flags
column of results when the following command is executed:
root@smw:~
xtcli status -t l0 s0
if
alert
or
reserved
is displayed in the
Flags
column of results when the preceding command is
executed, use the
xtclear_alert
or
xtclear_reserve
command to clear those statuses.
6. Ensure that the ANCCs are powered on by executing the command:
root@smw:~
xtalive
All 6 expected responses were received.
The above response may vary, depending on the number of sub-racks in the system. The previous example
displays a response the system would return if there are 3 sub-racks in the rack.
7. Become the
crayadm
user.
root@smw:~
su - crayadm
8. Initialize the High Speed Network (HSN) by executing the command:
crayadm@smw:~
xtbounce --linktune s0
This may step a few minutes to finish executing.
9. Use the HSS
rtr
command to request routing for the HSN
crayadm@smw:~
rtr -R s0
10. Exit to become the root user again.
crayadm@smw:~
exit
11.
12. Power on all the compute nodes of the system by executing the
ux-nid-power-on
script.
For more information, see the
ux-nid-power-on
man page.
root@smw:~
ux-nid-power-on all
Once all the node IDs have reported that they are up, wait for 5 or so minutes. The login nodes take longer
than the rest of the nodes.
