The admin user has comprehensive privileges, including the ability to manage certificates.

The security user is specifically designed for managing security-related tasks, including certificate management.

Reference: NetApp SANtricity Unified Manager User Guide, which details user roles and permissions.

The E2800 controller supports Fibre Channel (FC) and iSCSI as base host connectivity options.

FC provides high-speed connectivity for SAN environments.

iSCSI allows for IP-based storage networking, facilitating connectivity over existing Ethernet networks.

Reference: NetApp E2800 Series Hardware Guide, which lists supported host interfaces.

Identify the Orphaned Volume:

Step: Use SANtricity System Manager to identify the orphaned volume.

Reason: To determine which volume has lost its mirror relationship.

Remove the Mirroring Relationship:

Step: Access the mirroring settings for the orphaned volume and remove the existing relationship.

Reason: The current relationship is invalid and needs to be removed to reset the configuration.

Re-create the Mirroring Relationship:

Step: Establish a new mirroring relationship for the previously orphaned volume.

Reason: To restore the asynchronous mirroring setup with a valid configuration.

Understand ALUA Path Configuration:

Step: Review the exhibit to determine the paths between the host and the EF280.

Reason: ALUA (Asymmetric Logical Unit Access) provides multiple paths for redundancy and load balancing.

Count the Paths:

Observation: Each controller has two ports connected to two separate FC switches, and the host is connected to each switch, providing two paths per controller.

Calculation: 2 controllers x 2 paths per controller = 4 total ALUA paths.

Analyze the Errors:

Step: Review the porterrshow output, which indicates CRC errors on port 5.

Reason: CRC errors typically point to issues with the physical layer, such as faulty hardware or connections.

Check Physical Connections:

Step: Inspect the SFPs, cables, and patch panels for damage or improper connections.

Reason: Faulty or improperly connected hardware can cause CRC errors.

Troubleshoot by Replacing Components:

Step: Swap out the suspected faulty components (SFPs, cables, patch panels) and observe if the errors persist.

Reason: Replacing faulty hardware usually resolves CRC error issues.

Enable AutoSupport:

Step: Configure AutoSupport on the EF570 system with the option to store data locally.

Reason: This allows the system to generate and save support data without needing immediate Internet access.

Set Interval for Data Collection:

Step: Set AutoSupport to run at regular intervals.

Reason: Regular intervals ensure that up-to-date support data is available for NetApp.

Manual Data Transfer:

Step: Periodically transfer the collected support data from the local storage to a server with Internet access.

Reason: This server can then send the support data to NetApp.

Send Data to NetApp:

Step: Use the server with Internet access to forward the collected support data to NetApp's support systems.

Reason: This ensures NetApp receives the necessary support data for ongoing maintenance and troubleshooting.

Verify that the E2812 host port SAS link up lights are illuminated

The link up lights on the E2812 host port should be checked to confirm that the physical layer connection is established. If the lights are not illuminated, it indicates that there is no physical link between the host and the E2812 system, which would explain why the host cannot access the volumes.

Verify that the correct SAS ports are in use on the E2812 system

Ensuring the correct SAS ports are used is critical. Using incorrect ports might result in connectivity issues. The documentation for the E2812 provides guidance on the appropriate ports to be used for direct connections to a host.

To support multiple mirroring relationships, each with different recovery point objectives (RPOs), the administrator should create multiple mirror pairs. Each pair can be configured with its own schedule and RPO, allowing for tailored data protection strategies that meet specific needs.

nsshow

The nsshow command on a Brocade switch provides detailed information about devices connected to the switch. It displays the name server database, which includes information about all devices (initiators and targets) that are logged into the fabric.
