Hi,<br />
Just check following things<br />
Go to Storage adepter &gt;&nbsp;Select the HBA Card &gt;&nbsp;check at the path colum &nbsp;is it showing any lun maped over there ?<br />
Try to rescan HBA card and IF LUN's are not showing at HBA card then there is some issue with the Storage Zoning. <br />
Else issue should get resolve post rescan of HBA card.

vmware the storage backing virtual disk .vmdk has permanent device loss<br />

Looks like a datastore is down. &nbsp;Is there a way to fix from the command line?

VMWare 5

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.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
