c. If both MGMT0 and MGMT1 started, and resources are correct, proceed to turn on the OSS nodes.
16. Change to root.
[admin@sn11100n000 ~]$
sudo su- root
Log in as

. If a password is requested, use either
crayadm
or

.
17. Check to see which nodes are powered on:
[root@sn11100n000 ~]#
pm -q
on: sn11100n[000-003]
off:
unknown:
18. Power on the remaining nodes, as root:
[root@sn11100n000 ~]#
pm -1 desired node [00x-00x]
sn11100n[00x-00y]
IMPORTANT: For large systems, to avoid system power surge and network timeouts, limit selected
nodes to fewer than 50 nodes at one time.
19. Verify that the nodes are powered on:
[root@sn11100n000 ~]#
pm -q
on: sn11100n[000-003]
off:
unknown:
20. Verify that the resources have started:
[root@sn11100n000 ~]#
pdsh -a date | sort
The output shows all nodes in sequential order, and their status. This may take several minutes.
21. To continue system operation, verify that the system is in Daily mode:
[root@sn11100n000 ~]#
cscli cluster_mode --status
cluster_mode: Cluster is in 'Daily' mode.
cluster_mode: name: sn11100n
cluster_mode: UUID: 15fd9368-d665-11e5-9b44-0025901f832e
a. If the cluster is indicated to be in Daily mode as shown, power up is complete.
b. If the system is not in Daily mode, contact Cray hardware product support (HPS).
