How to Use the Export Switch to Backup and Restore Switch Configurations
Export switch lets you backup and restore switch configurations. This can be useful in case of hardware failure or switch replacement.
When you use the running-config-show command, Netvisor takes a back-up of the switch configuration and stores it in /nvOS/export directory. You can then import it onto a new replaced switch using the switch-config-import command. Here we will discuss about Export ‘switch’ (imported as ‘switch’) was not found in ‘react-router-dom’
SANnav Management Portal
The SANnav Management Portal is a next-generation SAN management solution that empowers IT administrators to be more efficient and productive by providing comprehensive visibility into the SAN environment. The tool transforms information about SAN behavior and performance into actionable insights that enable administrators to quickly identify, isolate, and correct problems before they impact business operations.
Powered by Brocade Autonomous SAN technologies, the SANnav Management Portal provides an intuitive one-click drill-down interface that streamlines the SAN management process for up to 25 users simultaneously. The browser-based graphical user interface eliminates the need to send hundreds of individual command-line interface (CLI) commands to multiple switches, allowing SAN administrators to configure a diverse range of devices and zones quickly and accurately.
In addition to a comprehensive set of SAN inventory and host-storage mapping features, the SANnav Management Portal also includes alarm features that reduce and summarize the many raw events and MAPS violations generated by SAN switches into a manageable number of alerts. These alarms help administrators to quickly track issues and take immediate corrective actions that optimize SAN performance.
* SAN health monitoring – Gathers and analyzes millions of real-time telemetry data points from across the SAN network, and contextualizes it into visual dashboards to help the administrator quickly detect and diagnose issues. The dashboards provide overall SAN health scores that indicate whether the fabric is healthy, degraded, or depleted in terms of resources such as storage, ports, and servers.
For example, the SAN traffic congestion dashboard displays E_Port and F_Port bandwidth usage in real-time as well as up to 2 hours ago, so the SAN administrator can identify the most congested ports for troubleshooting. The dashboard also provides a consolidated view of the number and location of MAPS violations, such as TCP timeouts, to quickly identify hot spots for investigation.
The SANnav Management Portal also offers policy-based configuration management, which applies consistent switch and monitoring configurations to all environments that it manages using the customer’s “golden” configuration policy. When a switch experiences a configuration drift, the SANnav Global View aggregates these drifts into a dashboard summary widget and allows the administrator to examine what has changed and enforce the customer’s golden configuration policy.
SAN navigation tools, such as SANnav Management Portal and SANnav Global View, enable administrators to transform information about SAN switches, host-storage devices, and other components into intelligent insights that allow them to quickly identify, isolate, and resolve issues. They also free up operational cycles so administrators can focus on more complex tasks such as accelerating configuration policy management and reducing security risks.
Managing SAN Fabric Zoning
The SANnav Management Portal and SANnav Management Portal Global View zoning features provide a rich set of insights that enable administrators to easily perform high-level zone configurations and check for consistency between fabrics across the SAN. For example, you can verify that the correct zones are in place for host ports. You can also verify that all SAN fabrics are consistent with their configurations for storage.
One of the most powerful new zoning features in SANnav 2.2 is the Zone Inventory view, which provides a visual representation of a fabric zoning tree. It displays a flat table with rows and columns, which helps to interpret the relationship between zoning objects and their edges.
You can filter the Zone Inventory to see only hosts, or to only show zones that refer to storage. It also gives you the option to display the zoning data in an ordered manner, so you can focus on specific zones or aliases for more detailed analysis.
In addition, the Zone Inventory view allows you to see zoning use cases for hosts and storage in multiple SAN fabrics. It also allows you to quickly identify if a certain zoning configuration is valid for a particular fabric, which can be important in determining whether a configuration is in compliance with the current standards.
SANnav Management Portal alarms are designed to reduce and summarize SNMP traps, RASlog, and syslog events that FOS switches send to SANnav Management Portal from the switches into a manageable number of alarms. These alarms are useful for identifying trends or warning of potential issues that may arise in your SAN.
SANnav Management Portal also features an on-demand support save collection that is fast and easy to execute. However, if more than two switches are selected in bulk, the on-demand support save process can take a long time to complete. This is because SANnav uses an internal SCP/SFTP server that has a switch limit, so it cannot support more than two switches at a time.
SANnav Host-Storage Mappings
One of the most challenging parts of managing a large data center is the task of determining what hosts and zones are connected to which ports. SANnav is the perfect tool for achieving this goal. SANnav uses a combination of Name Server and FDMI data to provide a comprehensive list of all connected devices (hosts, ports, and VLANs) and their associated attributes. It even goes one better by allowing you to drill down into the finer points of your host-to-switch mappings using sophisticated data mining techniques.
SANnav also has a number of other tools to help you get your data center humming along on the right foot. Among other features, SANnav has a highly interactive dashboard that makes it possible to easily navigate through multiple layers of data while remaining in the know about what is going on at each layer of the data center hierarchy.
SANnav Backup and Recovery is a feature that allows a SANnav client to save the current configuration of switches on a local disk, which can then be restored in case a switch fails. In addition to this, a SANnav client can also save the latest version of a switch s firmware.
If the SANnav Management Portal server is restored from a backup and then migrated to a new SANnav Management Portal installation, high granularity performance data, FCIP performance data, flow statistics and violations will not be collected. This is because a signed security certificate that was used in the previous SANnav installation is replaced with a self-signed certificate during the migration process.
When a SANnav Management Portal user makes a change to the Users page after installation or after SANnav service restart, the operation may fail with the message, “User update failed due to an internal server problem”. In this situation, you need to retry the operation and it will succeed.
The SANnav Management Portal client supports a number of different protocols to connect to a remote SANnav server. These include FTP, SCP, and SFTP. When a user configures a connection for a remote SANnav Management Portal client, the user must make sure to set a correct cipher type. This is important for a SANnav management portal client to access the internal SANnav repository of switch supportsave and firmware download files.
For SANnav Global View to work properly, the SANnav management server must be connected to the Internet. This can be done through a dedicated IP address or a domain name. This is done to provide additional protection to the SANnav management portal, as well as to ensure the highest possible availability of the SANnav Management Portal client.
This also enables a single connection to be made to multiple SANnav Management Portal servers. The SANnav Management Portal client can then be installed on any of the remote SANnav Management Portal servers and be configured to connect to each other.
A SANnav v2.2.2 Global View server can be deployed either on a bare-metal host or on a virtual machine (VM). The following table lists the recommended hardware and operating system requirements for a VM deployment of SANnav Global View v2.2.2.
