How do I clean my ESXI Datastore?
How to Cleanly Remove a vSphere Datastore
- Power down all VMs on the datastore you wish to remove.
- Unregister all powered down VMs from inventory.
- Unmount the datastore from all hosts.
- Detach the device from all hosts.
- Rescan for storage devices.
How do I reclaim datastore?
The first step is to identify the datastore(s) from which you want to reclaim storage. We will need the device name, and later the UUID. The next step is to identify if the device is detected as a thin-provisioned disk, and if it is VAAI-capable. I’ve shortened the output of the esxcli output to the necessary output.
What is storage reclaim?

What is the difference between PowerMax and Vmax?
Starting at the top, VMAX has been rebranded as PowerMax, gets a CPU upgrade and is made ready for coming storage networking and memory technologies. Two PowerMax systems were announced, the 2000 and 8000. These now use PowerBricks instead of V-Bricks, and the Hypermax OS becomes the PowerMax OS.

What type of storage is VMAX?
Who invented VMAX?
Massimo Tamburini
This shortens the length of the intake system from 150 mm to 52 mm. This system had its first appearance in the Yamaha stable with the 2006 YZF-R1. The MV Agusta F4 Tamburini was the first bike with such a system. Massimo Tamburini invented this idea.
What is the difference between VMFS and VMDK?
Both formats enable you to access the virtual machine’s disk (VMDK), but they differ in approach to storage, and VMware recommends VMFS for the vast majority of VMs. With RDM, VMDK files are only pointers to a VM’s disk data, while on VMFS the files also hold the data.
What is Unmap command?
VMware UNMAP is a command that allows a way to reclaim space from blocks that have already been written to after data that previously resided on those data blocks has been deleted. This deletion can come from either some type of application or the guest operating system.
What is difference between Vmax and VMAX3?
VMAX3 inherited the same engine based concept from VMAX. Basic building block for VMAX3 is Engines. Engine consists of two redundant director boards (controllers) that house global memory, front-end connectivity, back-end connectivity & internal network communications components.

How to reclaim unused space from the VMFS datastore?
The command helps thin-provisioned storage arrays to reclaim unused space from the VMFS datastore and thin virtual disks on the datastore. The VMFS6 datastore can send the space reclamation command automatically. With the VMFS5 datastore, you can manually reclaim storage space.
What is the space reclamation command in vmfs6?
The command helps thin-provisioned storage arrays to reclaim unused space from the VMFS datastore and thin virtual disks on the datastore. The VMFS6 datastore can send the space reclamation command automatically.
What is the space reclamation command in ESXi?
ESXi supports the space reclamation command, also called SCSI unmap command, that originates from a VMFS datastore or a VM guest operating system. The command helps thin-provisioned storage arrays to reclaim unused space from the VMFS datastore and thin virtual disks on the datastore.
