This article provides how to replace vSAN capacity disk. In the vSAN environment using SSD and hard disk drives together, the SSD used as the cache memory is called the Cache Disk, the hard drive used as the data space is called the Capacity Disk.

This article provides information about exporting the Tech Support Report (TSR) / SupportAssist Collection, including the Operating System, Application Data, and the RAID controller log. This is done using the integrated Dell Remote Access Controller (iDRAC) command-line interface (CLI) of Dell PowerEdge servers generations 12, 13, and 14.

This document answers questions about SupportAssist Enterprise.

This is a general troubleshooting guide to help identifying if there is a problem with a physical disk in vSAN Clusters.

This document highlights minimum, recommended, and latest code versions for Dell Technologies PowerEdge 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.

The below article is a workaround mechanism to recover PowerEdge systems from critical log entry "SWC5008 Unable to access Front LED Panel because of a hardware error condition" for a few versions of the iDRAC.

NVIDIA has updated the signing certificate for its UEFI network driver from Microsoft UEFI CA 2011 to Microsoft UEFI CA 2023. PowerEdge 17G platforms already trust the CA 2023 certificate, but 15G/16G and earlier servers require a BIOS update released in December 2025. Systems without this updated certificate support may fail to initialize the NIC UEFI driver when Secure Boot is enabled.

PowerEdge servers do not support operating system installation, or boot from direct CPU‑attached NVMe SSD drives if the metadata format size is not set to 0.

PowerEdge connected Dell NVMe SSDs with the Limited Retry (LR) bit set may experience an increase in failures due to elevated media and data‑integrity error rates.

Dell Samsung PM893 SSDs with Firmware HJ55 or Earlier Experience Premature SMART Failures

New deployments of OpenManage Enterprise 4.4.0 are experiencing service failures after configuring the time zone for GMT +02:00 Helsinki, Kyiv, Riga, Sofia, Tallinn, Vilnius. The issue is only seen on fresh deployment of OpenManage Enterprise (OME) 4.4.0 on Hyper-V. Deploying OpenManage Enterprise (OME) on other hypervisors is not impacted.

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

The "Predictive failure reported for disk x" error continues to be logged every 24 hours, even after the identified drive has been replaced. The issue only affects drives connected to PERC Controllers in RAID configuration.

Leveraging the 'Reboot Required' filter and selecting all items in this filtered view results in the 'make compliant' job applying all non-compliant firmware components. An unexpected reboot of the target is seen as components that do require a restart are deployed to the target. The issue is only seen if selecting all objects and using the 'Reboot Required' filter. All other filters work as designed.
