Dell EMC PowerVault ME4012

This document highlights minimum, recommended, and latest code versions for Dell Technologies Enterprise and Datacenter Infrastructure products. We carefully evaluate and monitor code deployment data to ensure that product releases meet our stringent expectations to provide our customers with reliable products and solutions.

Dell technical support engineers may ask you to send or collect a support log bundle to aid analyzing and resolving issues with your PowerVault ME5 series array. There are different methods to do this outlined in the article.

This article covers the steps to recover access to the PowerVault manager or CLI when the managed level user password has been lost. This procedure requires physical access to the array by the administrator using a serial cable provided with the array.

Restarting controller processors can be required by a configuration change or to resolve an operational problem. Shutting down controller processors is recommended before either removing a controller module from its enclosure or powering off its enclosure for maintenance or a move.

Administrators may be unable to complete the firmware upgrade from ME5.1.0.1.0 to later versions. Activation does not happen when partner firmware upgrade is enabled. As a temporary measure, disable partner firmware update, upload and activate the update on one or both controllers before reenabling the partner firmware upgrade.

Dell AIOps (formerly CloudIQ) is a cloud-based application that provides simple, proactive monitoring and troubleshooting of your Dell IT infrastructure including integration with VMware. It leverages machine learning to proactively monitor and measure the overall health of servers, storage, and switches through intelligent, comprehensive, and predictive analytics. Dell AIOps is available at no additional charge for Dell products covered with a valid ProSupport (or higher) contract.

Applications using SMI-S fail to communicate with ME4 arrays upgraded to GT280R010-01. Update the controller firmware to GT280R011-01, available on Dell Support, to address the issue.

Most administrators do not open PowerVault Manager every day to check the system status. If a fault develops, the problem may not become obvious for a long time due to the levels of redundancy provided by the array. It is highly recommended that Dell ME array administrators configure at least one notification path so they can quickly respond to any critical events that may arise on the system.

PowerVault ME administrators are advised to update Samsung SSD drive models on firmware DSG5 to DSG8 (or later) and drive models with firmware DWG5 to DWG8 (or later) to resolve an issue that may cause multiple drives to go offline, potentially leading to disk groups becoming offline in a quarantine state. Applying drive firmware updates requires a maintenance window, in addition, this specific drive update requires the array to be shut down.

PowerVault ME4 systems that are monitored by Dell CloudIQ may stop receiving updates. This article outlines how to resolve issues on PowerVault ME4 series arrays that may prevent telemetry updates being received.

On PowerVault ME52xx series PowerVault Manager displays the ESE Version. Embedded Service Enabler (ESE) is the Dell API used by SupportAssist to send telemetry either direct to a Dell endpoint (esrs3-core.emc.com) or locally installed Secure Connect Gateway appliance endpoint.

Applications like video streaming applications (for example, recording) that generate sequential write I/O benefit from using aligned disk groups to improve I/O performance. Other use cases the disk group configuration meets users storage requirements and provides adequate performance to serve their application and expected end-user I/O responses.

Dell PowerVault ME5 remediation is available for a Client Desync Attack vulnerability that may be exploited by malicious users to compromise the affected system.

This article covers multipath.conf settings for Linux based on Best Practices guides for MD and ME storage.

The Dell Enterprise Knowledge Base provides technical solutions, error message information and troubleshooting guides for PowerVault products.

This article covers the steps to gather the support bundle through File Transfer Protocol (FTP) for PowerVault ME Series storage products.

PowerVault ME5 controllers may randomly reboot while the controller supercapacitor is being charged. This symptom is caused by the charging circuit generating noise on the 12V line. Upgrade PowerVault ME50 series systems controller firmware to version ME5.1.2.1.5 or later, and ME52 series systems controller firmware to ME5.2.0.0.2 or later.

This article outlines options when expanding a disk group or adding capacity to a pool on PowerVault ME storage.

These instructions show how to create two custom SSL certificates, one for each controller, using OpenSSL and Active Directory Certificate Services (ADCS). The certificates work with both a common Fully Qualified Domain Name (FQDN) for both ME4 controllers and with the FQDN system name of each individual controller.

This article covers the steps to install a custom certificate through FTP for Dell PowerVault ME Series storage products.

PowerVault ME52xx series arrays enable a feature called Intelligent Drive Firmware Update (IDFU) by default. The Intelligent drive firmware upgrade feature enables administrators to apply online firmware updates to drives without the need for a maintenance window as was the case with previous generation PowerVault ME50xx and ME40xx controllers.

This article should be followed even if the ME484 is connected as an expansion to a main array (ME4012/ME4024/ME4084) and is used as a JBOD by connecting directly to host.

Upgrading your PowerVault ME4 Series storage system ensures optimal performance, enhanced security, and access to the latest features and issue fixes. Dell releases firmware updates for both controllers and disks to improve system stability and compatibility.

How to find the serial number, product ID, or Product Serial Number Tag (PSNT) that is required to open a service request or support case for Dell Storage and Data Protection hardware products.

Scheduled tasks such as snapshot, replication, disk group scrubs, or SupportAssist telemetry uploads may stop working after daylight savings time changes.

The integrated SupportAssist feature can be configured to Connect Directly or Connect using Gateway Server to send telemetry data from the PowerVault ME5. PowerVault ME5 can only connect to Secure Connect Gateway (SCG) Virtual Edition.

This article outlines how to enable SupportAssist on PowerVault ME5 & ME52 series arrays using a direct connection to Dell endpoints.

Alerts received are about CPU and sideplane but ME4 events log only indicate sideplane ambient temp as high. Apparently the alert about CPU temp high was a false positive alert. Resolve any environmental cooling issues and update to firmware GT280R010-01 or later.

Dust or chemical contamination at the endface of a fiber optic LC connector or transceiver module impedes signaling. Dell engineering teams have verified cases in which a fully functional port appears to be a bad port because dirty optical connectors manifest as a port failing loop testing with acceptable power measurement levels. Cable connectors should be cleaned and when stored must be protected from dust particle or chemical contamination.
