Prerequisites for SmartFabric OS10 deployments
Before you upgrade, ensure that the following prerequisites are met:
● Ensure that you back up the configuration data and license files in an external storage.
● On the Z9100-ON switch, do not upgrade the OS10 software. Instead, perform an ONIE fresh installation. Follow the
procedure described in Upgrade from OS9 to OS10 using the ONIE-Install OS option.
Prerequisites for solution deployments
Before you upgrade, ensure that the following prerequisites are met:
For a list of supported versions, see the Networking Solutions Support Matrix.
● For SFS deployments on S and Z Series switches, upgrade to Release 10.5.0.7P3 before you upgrade to Release 10.5.1.1 or
later.
● For MX deployments, use the OME-M console to upgrade the IOMs in the fabric. For instructions on upgrading the IOMs,
see the Dell EMC MX Networking Deployment Guide.
● For VxRail solution, before upgrading OS10 nodes, perform the following:
1. Disable failback on all configured port-groups.
a. On vCenter, go to the Networking tab and make the following settings on each port group:
i. Click Action -> Edit Settings -> Teaming and Failover and set Failback to No.
2. Move OMNI to Maintenance mode.
a. For OMNI 1.2 or greater, go to Home -> Support -> click Enable Maintenance Mode.
b. For OMNI 1.x versions, Login to OMNI shell as root.
c. Stop the Dell vCenter App service using systemctl stop dellvcenterapp.service.
d. Check to confirm if the service is stopped using systemctl status dellvcenterapp.service.
3. This step is only applicable to the S4112-ON switches:
a. Upgrade all the switches from 10.4.3.x to 10.4.3.6P3 through CLI starting with the backup switch.
4. Upgrade all the switches to 10.5.0.7P3 through OMNI.
5. Disable OMNI maintenance mode.
a. For OMNI 1.2 or greater, go to Home -> Support -> click Disable Maintenance Mode.
b. For OMNI 1.x versions, Start the Dell vCenter App service using systemctl start
dellvcenterapp.service.
c. Check to confirm if the service has started using systemctl status dellvcenterapp.service.
6. Enable failback on all configured port-groups.
a. On vCenter, go to the Networking tab and make the following settings on each port group:
i. Click Action -> Edit Settings -> Teaming and Failover and set Failback to Yes.
● Single rack SFS upgrade from Release 10.5.0.7P3 to 10.5.2.2 or 10.5.2.3 with breakout configuration on uplink
connections
For VxRail single rack deployment with two leaf switches, if there is breakout configuration on the uplink connections, do not
use the OMNI GUI for upgrade. Use the OS10 CLI to and follow the steps listed below to upgrade the switches:
1. Upgrade the SFS standby node from the CLI. After the SFS standby node is upgraded and joins the cluster, perform a
switchover through the Linux shell to make this node the SFS primary node (Master). To do this, you must enter the
following commands:
system sudo -i
python /opt/dell/os10/bin/rest-service/tool/dnv_cli.py
dnv$ switchover
dnv$ exit
2. Upgrade the second node after the switchover.
