Hi, we have DellEMC VXRAIL VMware vSAN Cluster consist of 4 ESXi hosts. We are using vSAN iSCSI targets hooked up to Virtual Machines for Windows Server 2012 R2, Failover clustering. The cluster works fine after configuring. <br />
<br />
However, when I run the cluster validation test, it fails with below error:<br />
<br />

<blockquote>
Two disks have been found on node SRVVDB01.domain.local that cannot be distinguished from one another. The disks involved have disk signature c10b5a63, SCSI page 83h VPD descriptor iqn.1998-01.com.vmware.52e<wbr />5e355fe26a<wbr />1cb-a80ef9<wbr />982d7fc722<wbr />,L,0x00000<wbr />0000000000<wbr />0, SCSI page 80h VPD Serial Number VITSERIALbaebec5cee2b845f0<wbr />bcde4434b5<wbr />acd30. Please verify the storage configuration. You must either mask (unpresent, detach) one of these LUNs at this node, or, run validation and specify a disk list that includes only one of these disks, for example by using the Test-Cluster cmdlet in Windows PowerShell.<br />

VMware iSCSI targets in Windows Server Failover Clustering.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

MS Windows Clustering

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft Server OS

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
