When the NVRAM status LED on an XtremIO X2 is flashing red at one-second intervals, it indicates an uncorrectable error. This is a critical status that typically signifies a hardware malfunction or failure within the NVRAM module, which requires immediate attention.NVRAM, or Non-Volatile Random Access Memory, is crucial for retaining data integrity during power losses or system crashes1.

The steps to address this issue usually involve:

Investigating the system logs to identify the specific nature of the error.

Contacting Dell EMC support for guidance on diagnosing and resolving the issue.

Following the recommended procedures for troubleshooting or replacing the affected NVRAM module, as per the support team’s instructions.

It is important to resolve such errors promptly to prevent potential data loss and to maintain the overall health and performance of the storage system1.

=========================

For an XtremIO X2-S, the ports used on the InfiniBand switches for an Inter-Switch Link (ISL) connection are typically high-numbered ports, which are usually at the end of the port range on the switch.While the specific port numbers can vary depending on the switch model and configuration, ports 35 and 36 are commonly used for ISL connections in many configurations1.

The process to identify the ISL ports is as follows:

Access the InfiniBand switch via the management interface.

Use the appropriate command to list the port configuration (this command can vary based on the switch’s firmware).

Identify the ports configured for ISL, which will be indicated in the port configuration settings.

It’s important to refer to the official Dell XtremIO Maintenance Achievement document or the InfiniBand switch documentation for the exact port numbers as they can differ based on the switch model and the cluster configuration1.

When deploying a virtual XtremIO Management Server (XMS), it is recommended to allocate a virtual hard drive space of200 GB.This recommendation is based on the requirements for the operating system, the XMS application, and additional space for updates, logs, and other system files that may be generated during operation1.

The deployment process would typically involve:

Preparing a virtual environment that meets the minimum hardware specifications.

Allocating the recommended virtual hard drive space of 200 GB to ensure adequate room for the XMS application and associated data.

Proceeding with the installation of the XMS application on the prepared virtual machine.

It is important to follow the official Dell XtremIO documentation to ensure that the virtual environment is correctly configured to support the XMS application2.

In preparation for a dual-to-quad online cluster expansion, the active cluster cabling should be validated using the Easy-Install menu. This menu provides a guided and automated way to ensure that all cabling is correctly connected and verified, minimizing the risk of errors and ensuring a smooth expansion process.
