Fabric-Attached MetroCluster Installation and Configuration Guide
- Deciding whether to use the Fabric-attached MetroCluster Installation and Configuration Guide
This guide describes how to install and configure the MetroCluster hardware and software components in a fabric configuration. - Preparing for the MetroCluster installation
As you prepare for the MetroCluster installation, you should understand the MetroCluster hardware architecture and required components. - Considerations for configuring cluster peering
Each MetroCluster site is configured as a peer to its partner site. You should be familiar with the prerequisites and guidelines for configuring the peering relationships and when deciding whether to use shared or dedicated ports for those relationships. - Considerations for MetroCluster configurations with native disk shelves
The MetroCluster configuration supports installations with native (Lenovo) disk shelves only or a combination of both. - Considerations for ISLs
You must determine how many ISLs you need for each FC switch fabric in the MetroCluster configuration. In some cases, instead of dedicating FC switches and ISLs to each individual MetroCluster configuration, you can share the same four switches. - Considerations for using TDM/WDM equipment with fabric-attached MetroCluster configurations
- Considerations when using unmirrored aggregates
If your configuration includes unmirrored aggregates, you must be aware of potential access issues after switchover operations. - Considerations for firewall usage at MetroCluster sites
If you are using a firewall at a MetroCluster site, you must ensure access for certain required ports. - Choosing the correct installation procedure for your configuration
You must choose the correct installation procedure based on the number of nodes in the MetroCluster configuration. - Cabling a fabric-attached MetroCluster configuration
The MetroCluster components must be physically installed, cabled, and configured at both geographic sites. - Configuring hardware for sharing a Lenovo B6510 FC SAN switch FC fabric during transition
- Configuring the MetroCluster software in ONTAP
You must set up each node in the MetroCluster configuration in ONTAP, including the node-level configurations and the configuration of the nodes into two sites. You must also implement the MetroCluster relationship between the two sites. - Verifying local HA operation
If you have a four-node MetroCluster configuration, you should verify the operation of the local HA pairs in the MetroCluster configuration. - Verifying switchover, healing, and switchback
You should verify the switchover, healing, and switchback operations of the MetroCluster configuration. - Configuring the MetroCluster Tiebreaker software
You can download and install the MetroCluster Tiebreaker software on a third site. - Protecting configuration backup files
You can provide additional protection for the cluster configuration backup files by specifying a remote URL (either HTTP or FTP) where the configuration backup files will be uploaded in addition to the default locations in the local cluster. - Testing the MetroCluster configuration
You can test failure scenarios to confirm the correct operation of the MetroCluster configuration. - Considerations when removing MetroCluster configurations
You can remove the MetroCluster configuration from all nodes in the MetroCluster configuration or all of the nodes in a disaster recovery (DR) group. After removing the MetroCluster configuration, all disk connectivity and interconnects should be adjusted to be in a supported state. If you need to remove the MetroCluster configuration, contact technical support. - Using the Unified Manager for DM Series and ThinkSystem Storage Manager for DM Series for further configuration and monitoring
The Unified Manager for DM Series and ThinkSystem Storage Manager for DM Series can be used for GUI management of the clusters and monitoring of the configuration. - Considerations when using ONTAP in a MetroCluster configuration
When using ONTAP in a MetroCluster configuration, you should be aware of certain considerations for licensing, peering to clusters outside the MetroCluster configuration, performing volume operations, NVFAIL operations, and other ONTAP operations. - Contacting Support
You can contact Support to obtain help for your issue. - Notices
