For SpycerNodes (SNO2U, SNO5U, SNO2, SNOSC) and SpycerMedia Gateways (SMGW).
Shutdown/power off procedure
This procedure will shutdown and power off all of the SpycerNodes (SNO) and SpycerMedia Gateways (SMGW) directed from one of the SNO Node.
1. Log into one of the SNO Node from ssh.
C:\Users> ssh root@192.168.100.38
root@192.168.100.38's password:
Last login: Thu Aug 18 13:37:50 2022 from 192.168.100.220
2. Shutdown/poweroff all off the SMGW Nodes.
[root@sno-101514-A ~]# mmdsh -N cesnodes "shutdown now"
smgw-190012: Connection to smgw-190012 closed by remote host.
mmdsh: smgw-190012 remote shell process had return code 255.
smgw-190001: Connection to smgw-190001 closed by remote host.
mmdsh: smgw-190001 remote shell process had return code 255.
3. Wait about 1 minute.
4. Shutdown/poweroff all off the SNO Nodes.
[root@sno-101514-A ~]# mmdsh -N nsdnodes "shutdown +1"
Broadcast message from root@sno-101514-A (Fri 2024-11-15 11:45:41 PST):
The system is going down for poweroff at Fri 2024-11-15 11:46:41 PST!
sno-101514-A: Shutdown scheduled for Fri 2024-11-15 11:46:41 PST, use 'shutdown -c' to cancel.
sno-101512-A: Shutdown scheduled for Fri 2024-11-15 11:46:41 PST, use 'shutdown -c' to cancel.
sno-101512-B: Shutdown scheduled for Fri 2024-11-15 11:46:41 PST, use 'shutdown -c' to cancel.
sno-101514-B: Shutdown scheduled for Fri 2024-11-15 11:46:41 PST, use 'shutdown -c' to cancel.
sno-witness-2: Shutdown scheduled for Fri 2024-11-15 14:46:41 EST, use 'shutdown -c' to cancel.
7. Wait a few minutes and confirm power are off (most of lights will be off and fans no longer running).
8. You may turn the power switches to the off position in the rear (if available) or unplug the power cords.
Startup / power on procedure
1. Power on all the SNO Nodes first.
Make sure the power cords are connected and switches are in the on positions in the rear, the unit will auto power up when power is restored.
or
- You may use the IPMI web interface to remotely power up the SNOs, or
- You may press the little recessed power On/Off button with a paper clip at the rear of each of the two SNO controllers:
2. Power on all the SMGW Nodes next.
Make sure the power cords are connected.
- You may use the iDRAC web interface to remotely power up the SMGW, or
- You may press the power on/off button at the front of the SMGW.

3. Allow about 10 minutes for the boots to complete, ssh into one of the Nodes to confirm GPFS states are active:
[root@sno-101514-A ~]# mmgetstate -aL
Node number Node name Quorum Nodes up Total nodes GPFS state Remarks
-------------------------------------------------------------------------------------
1 sno-101514-A 2 3 9 active quorum node
2 sno-101514-B 2 3 9 active
27 sno-101512-A 2 3 9 active quorum node
28 sno-101512-B 2 3 9 active
31 sno-witness-2 2 3 9 active quorum node
37 smgw-190012 2 3 9 active
38 smgw-190001 2 3 9 active
40 Rocky84 2 3 9 active
41 Rocky89 2 3 9 active
4. If you have SMGWs, check protocol service states.
