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.

This article describes 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.

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.

Best Practices to follow during ME4 Controller replacement.

Dell Technologies advises against downgrading Hard Drive or SSD firmware, except in validated scenarios, due to unpredictable results and version reporting issues.

Administrators are unable to change default management IP address, subnet mask, and gateway on single controller using PowerVault Manager. Use the PowerVault command-line interface (CLI) to make the changes.

When one of the internal PCIe buses is degraded. The hardware bus is unable to use optimal speeds. (bus: 5, actual speed: Gen1, expected speed: Gen2). This warning message may be observed on PowerVault ME4 series controllers prior to release G280R004-01. Upgrade the ME4 controller firmware to the latest.

Creating a linear RAID array using the ME5 user interface, selecting all available disks may result in the Sub Groups not being populated correctly. This issue occurs across all RAID levels.

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

Seagate Summit SAS/SATA drives report medium errors or sense key 3/11 on PowerEdge and PowerVault systems due to a firmware issue causing weak writes to a drive sector.

This article describes Self‑Monitoring, Analysis, and Reporting Technology (SMART) events on Dell PowerVault ME5 systems. It explains how to identify the events using event logs and alert history, and outlines the required corrective actions to maintain system health and data integrity.

PowerVault administrators must inspect and confirm electrical power is available to the PCM or PSU and the rocker switch on each PSU or PCM is set to on position before contacting Dell technical support to report a faulted power supply.

Dell Samsung Serial Attached SCSI (SAS) PM1653 and PM1655 solid state drives may report excessive Sense Key faults 0x3, 0x11, 0x0, or 0x4, 0x29, 0x4. These faults have the potential to cause unexpected drive issues.

The Dell HBA465e or HBA355e SAS host bus adapter (HBA) may be supplied as a drop in box (DIB) item alongside PowerEdge servers. This article provides direction on selecting an appropriate PCI-e slot.

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). This is 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.

Administrators may report being unable to access PowerVault Manager, unable to open an SSH session, or log in to a serial session. The storage controller continues to serve data to connected frontend hosts. Upgrade the controller firmware to version ME5.1.2.2.1 or later.

PowerVault ME5 arrays User Interface (UI) shows blank certificate information. The CLI ('Command-Line Interface') displays certificate information as expected.

On ME4 arrays customer might experience SNMP V2/V3 Services stops responding after 24 Hrs post upgrading the controller firmware to GT280R010-01 firmware when the array is monitored using third party Management Software.

PowerVault ME5 reports an invalid firmware bundle on the controller. Power down and ensure that the SAS cables are connected in the right order per the deployment guide. The correct firmware is applied once the attached enclosures, then the ME5 enclosure are powered on.

This article helps with isolating faults when an Ethernet port link does not come up or the port does not negotiate the expected link speed with PowerVault ME5 iSCSI controller modules.

Administrators may receive a Health Alert warning "Lost connectivity to the Dell SupportAssist backend." On examination of the Event History log, an informational event 362 "Scheduler: SupportAssist is not registered with the Dell backend" is reported at regular intervals.

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 discusses shutting down and switching off an ME5 SAN array as part of a maintenance window or equipment move and some considerations before doing.

SupportAssist implementation on PowerVault ME5 models ME5012, ME5024, and ME5084 must be enabled using an Access Key and PIN two-factor authentication method.

SupportAssist, when enabled, checks once every 7 days for the latest controller and disk drive firmware updates available for your array. When a disk or controller firmware update is detected, the ME4 records this as a warning level entry in the event log.

On the PowerVault ME50xx series, when SupportAssist is enabled and can connect to the Dell endpoints or using Secure Connect Gateway, the service periodically looks for available controller or disk firmware updates.

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.

A controller firmware upgrade is needed on PowerVault ME4 series to allow sending notification email alerts when the SMTP server uses TLS 1.2

PowerVault ME4 series requires iSCSI host initiators to follow the standard IQN format. Or the host may be reported with a fiber channel (FC) worldwide name (WWN).
