Make sure all the service profiles are associated as shown below. As shown above, make sure all the server nodes has no major or critical fault and all are in operable state. Log in as admin user into Nexus Switch A and run the following commands to set global configurations and jumbo frames in QoS.
Log in as admin user into Nexus Switch B and run the same above commands to set global configurations and jumbo frames in QoS. To create the necessary virtual local area networks VLANs , follow these steps on both Nexus switches. Login as admin user into Nexus Switch A. In this topology, we defined a total of 3 vPCs. To create vPC peer-link between two Nexus switches, complete the following steps:.
You may choose appropriate number of ports for your needs. To create the necessary port channels between devices, follow these steps on both Nexus Switches:. Fabric Interconnect uplink ports. Cisco Nexus PX-E ports.
Allowed VLANs. Port Channel FI-A. N9KA P Note: VLAN 10 needed for failover. N9KB P Port-Channel FI-B. Note: VLAN needed for failover. To create the necessary port channels between devices, follow these steps on both Cisco Nexus Switches:. MDS Switch. MDS Switch Port. Fabric Interconnect. FI Port. MDS Switch A. MDS Switch B.
Storage Controller We used 4 HBAs for each Server. To create and configure the Fiber Channel Zoning, complete the following steps:. FC ports CT0. FC2, CT1. FC3, CT1. Log in as admin user and run the following commands. Create a zone for each service profile. Login as admin user and run the following commands.https://ferwaigobackma.tk
FlashStack Data Center with Oracle RAC 12c on Oracle Linux - Cisco
After the zone for the Cisco UCS service profile has been created, create the zone set and add the necessary members. Activate the zone set by running following commands. The design goal of the reference architecture was to best represent a real-world environment as closely as possible. S on top of the stateless servers. Once the stateless servers were provisioned, following process was performed to enable Rapid deployment of 7 additional RAC nodes.
Zoning was performed on the Cisco MDS S switches to enable the initiators discover the targets during boot process. Installed Oracle Linux 7. The service profiles represent all the attributes of a logical server in Cisco UCS model. Using logical servers that are disassociated from the physical hardware removes many limiting constraints around how servers are provisioned.
This is a huge benefit in comparison to other appliance model like Exadata. In rare case of a server failure, it is easier to associate the logical service profile to another healthy physical server to reduce the impact. Log into Pure Storage dashboard. Enter the name of the host and click Create. This should create a Host entry under the Hosts category. WWNs will show up only if the appropriate FC connections were made and the zones were setup on the underlying FC switch.
Select the list of WWNs that belongs to the host in the next window and click Confirm. Make sure the zoning has been setup to include the WWNs details of the initiators along with the target, without which the SAN boot will not work. Select the host where the volume should be attached and click Confirm. This document does not detail the step-by-step OS installation, but only provides an overview of the process. Download Oracle Linux 7. If you see the following message in the KVM console while the server is rebooting along with the target WWPNs, it confirms the setup is done correctly and boot from SAN will be successful.
During server boot order, it will detect the virtual media connected as Oracle Linux cd.

It should launch the Oracle Linux installer. You can configure additional interfaces as part of post install steps. Figure OS Configuration. After OS install, reboot the server, complete appropriate registration steps. You can choose to synchronize the time with ntp server. All of them may have to be required on your setup. Please validate and change as needed.
The following changes were made on the test bed where Oracle RAC install was done. Once Oracle Linux 7. As most of organizations might already run hardware-based firewalls to protect their corporate networks, disable Security Enhanced Linux SELinux and the firewalls at the server level for this reference architecture.
Disable firewall by running following commands. Create and verify the Oracle users and groups in each cluster nodes. User accounts oracle, grid and groups dba, oinstall, asmdba, oper were created in the server.
Both grid and oracle was configured to have oinstall as the common primary group for the Oracle central Inventory to work. Default limit for number of user's processes to prevent. Ensure the multipathing packages are installed and enabled for automatic restart across reboots. Run "multipath -ll" command to view all the LUN id. Use noop scheduler for high-performance SSD. Reduce CPU overhead due to entropy collection. This eliminated reinstalling most of the pre-requisite O. S level packages and kernel level settings as well as helped to provision additional nodes in minutes.
The nodes were reconfigured with appropriate network interfaces and WWNs. Also zoning information was updated with the WWN information of the host and the targets so the Oracle database LUNs can be presented to the hosts. Pre-clone steps on the source Linux host. Post-clone steps on the source Linux host. Gather vHBA details for setup. Volume setup on Pure Storage for the clone. Target host setup.

Unconfigure the networking setup on the source host. This is to avoid the cloned host to come up with the same IP addresses and causing IP conflicts. Following set of commands identifies the device and disables them. If you have more than 2 interfaces, please disable them as well in the same format. User Input section. Please provide the details to the following variables.
