VMware VSAN

This is a firmware catalog which contains validated and certified firmware stack for selected Dell VMware vSAN Ready Nodes based on Dell customized ESXi 6.x branch-based Dell customized images.

vSphere 7.x and later ESXi host experiences a Purple Screen of Death (PSOD) creates a Zdump core dump that is auto‑encrypted. This happens when the host is using Virtual Machine encryption.

This article discusses what the OpenManage Enterprise Integration for VMware vCenter (OMEVV) is, what the latest release is, and consolidated resources for quick reference.

When ESXi hosts have the “Log Urgent Traces To Syslog” option enabled, urgent vSAN diagnostic traces are sent to the syslog target, causing Aria Operations for Logs (formerly vRealize Log Insight) to ingest excessive vsantraceurgent logs.

This KB explains how to perform the WSFC conversion at a high-level. It also covers converting an Oracle RAC environment from RDMs to shared VMDKs on NVMe/TCP, even though Oracle RAC does not require SCSI3‑PR. Oracle RAC can run on an SDC‑based VMFS datastore, but because PowerFlex does not support Clustered VMDK on SDC‑based VMFS, SCSI3‑PR‑dependent applications cannot use that configuration. Oracle RAC explanations are also high-level.

After deleting VM from disk, there are VM folders remaining in the data store which could not be deleted manually.

This article explains how to replace a cache disk in a vSAN configuration.

This article describes how to boot the ESXi server with Virtual Storage Area Network (vSAN) modules disabled.

vSAN (Virtual SAN) requires disk‑group layout conversion from 32‑bit to 64‑bit to use large drives (≥16 TB for space‑efficiency‑disabled, ≥4 TB for enabled). Health warning shows 32‑bit; fix by evacuating data and recreating the group. Without it, the large drive is ignored. Upgrading to vSphere 19 and recreating gave no 64‑bit option; capacity remains 64 GB with 20 TB disks, so the 16 TB limit persists.

This article explains how to identify the virtual machine (VM) that is using your .vmdk file and preventing it from being deleted.

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

The write I/O latency of VMs were high after replacing the vSAN capacity disk and exiting the maintenance mode.

Error uploading vmdk files larger than 250 GB to vSAN datastore.

This article describes how to check if the witness host is shared or dedicated. It is necessary to check if the 2-node cluster has a shared witness or dedicated witness before invoking VxRail LCM.

This article explains how to assign an Initial Company Administrator.

During a VSAN cluster node expansion task, a production VM became inaccessible for several hours resulting in data unavailable.

VXR0140A1 alarm triggers when vSAN (Virtual SAN) cluster storage space exceeds configured thresholds (vSAN 7.0 Update 2 onward). Check and reduce vSAN datastore usage per VMware KB 71003.

This article explains the relationship between SCSI reservation conflicts and Shared ESXi Datastores.

vCenter enables Active Directory (AD) and login by Active Directory users have notification "Password will expire in X days," customer must eliminate it.

This health-check looks Guest Unmap setting on each node, which if enabled, can cause significant vSAN performance issues and impact Virtual Machine (VM) operations.

Broadcom has announced the deprecation of vVols in VCF/VVF 9.0, with removal planned for 9.1. Customers using vVols with Dell Unity should avoid upgrading to VCF/VVF 9.0, as support will be limited to critical fixes only. Customers can migrate from vVols to Virtual Machine File System (VMFS) using Storage vMotion or XCOPY (starting in VCF 9.0).

The intent of this article is to provide the proper course of action to take if the notified mystic code takes place.

vSphere Distributed Switch (vDS) health check can label Virtual Local Area Network (VLAN) or Maximum Transmission Unit (MTU) as "Not Supported" if uplinks have varied VLAN, MTU mismatches, or VLAN None groups; mitigate by disabling it or ensure VLAN/MTU support.
