Unmounting a LUN using the vSphere ClientOtherwise, in the Configuration tab of the ESXi host, click Storage. Right-click the datastore being removed and click Unmount. A Confirm Datastore Unmount window appears. When the prerequisite criteria have been passed, click OK.
The ESXCLI command set allows you to run common system administration commands against vSphere systems from an administration server of your choice. The actual list of commands depends on the system that you are running on. Run esxcli --help for a list of commands on your system.
How to remove inactive datastore from vSphere 6.0?
- unmount the datastore.
- detach storage device.
- make sure it detached with esxcli storage core device detached list.
- permanently remove device config with esxcli storage core device detached remove -d naa. xxxx.
There is a quick and easy way to fix this, by restarting the management service on the host(s) that the vm guests reside on.
- Shell or console onto the host.
- Run the following command /etc/init.d/hostd restart.
- exit.
- Close the vsphere client.
- Open the vsphere client.
Remove vmkdump-filesExecute following commands on locking host: To un-configure dump-file, execute: esxcli system coredump file set -u . To remove previous configured dump-file, execute: esxcli system coredump file remove -f /vmfs/volumes/volume/vmkdump/11111111-2222-3333-4444-555555555555. dumpfile.
Restart Management agents in ESXi Using Direct Console User Interface (DCUI):
- Connect to the console of your ESXi host.
- Press F2 to customize the system.
- Log in as root.
- Use the Up/Down arrows to navigate to Troubleshooting Options > Restart Management Agents.
- Press Enter.
- Press F11 to restart the services.
How to delete VSAN datastore you'll need to:
- Evacuate all the VMs out of the VSAN datastore.
- Turn OFF VMware HA.
- Delete all VSAN disk groups Individually. Once done (for each of the hosts participating in the VSAN cluster), the local disks are available to be re-used….
- Deactivate VSAN cluster.
- Re-enable VMware HA.
In computer storage, a logical unit number, or LUN, is a number used to identify a logical unit, which is a device addressed by the SCSI protocol or by Storage Area Network protocols that encapsulate SCSI, such as Fibre Channel or iSCSI.
Datastore Heartbeating in vSphere enables the master host to better determine the true state of a slave host. It is used when the master can no longer communicate with a slave over the management network (no network heartbeats from the slave are being received). Expand the Datastore Heartbeating option.
Browse to the datastore in the vSphere Client. Right-click the datastore and select Maintenance Mode > Enter Maintenance Mode. A list of recommendations appears for datastore maintenance mode migration. (Optional) On the Placement Recommendations tab, deselect any recommendations you do not want to apply.
In your Windows VM open "Administrative Tools" ->"Computer Management" -> "Disk Management". Choose a volume you want to unmount. Right-click and select "Change Drive Letter and Paths". Select the volume's drive letter and click "Remove".
Procedure
- In the vSphere Client, browse to the vSphere HA cluster.
- Click the Configure tab.
- Select vSphere Availability and click Edit.
- Click Heartbeat Datastores to display the configuration options for datastore heartbeating.
To disable SDRS in the vSphere Web Client.
- Browse to the datastore cluster in the vSphere Web Client navigator.
- In the Manage tab, click Settings.
- Under Services, select Storage DRS and click Edit.
- Deselect the Turn ON vSphere DRS option and click OK.
on esx host, go to configuration tab, storage adapters, then highlight the vmhba (fc or iscsi) that the lun is on. Change from "devices" tab to "paths" tab scroll to target. There, you will find the system id of the netapp filer.
.sf = system file. .sdd = scsi device description.
Before unmounting a VMFS datastore, make sure that the following prerequisites are met: no virtual machines reside on the datastore. the datastore is not part of a datastore cluster. storage I/O control is disabled. the datastore is not used for HA heartbeat or Storage DRS.
Remove the RDM from the virtual machine:
- Click Edit Settings.
- Select the RDM hard disk.
- Click Remove. Select Delete from disk if it is not already selected.
- Click OK.
In the case of an orphaned virtual machine, the VM needs to be either re-registered if possible (if it has not been deleted) or removed from inventory. To re-register a virtual machine, navigate to the VM's location in the Datastore Browser and re-add the VM to inventory.
VMware PagesStorage DRS allows you to manage the aggregated resources of a datastore cluster. When Storage DRS is enabled, it provides recommendations for virtual machine disk placement and migration to balance space and I/O resources across the datastores in the datastore cluster.
Remove a vSphere Distributed Switch (VDS) from host
- Open the vSphere client.
- Click Home and the Networking icon in the inventory tab.
- Select the desired VDS (2)
- Select the hosts tab.
- Select the desired ESXi host, right click and select Remove from vSphere Distributed Switch (4)
To restore access to a disconnected host machine, you must reconnect to the host. Right-click the host in the System pane.

Remove from Inventory – this option unregisters the VM from the host and the vCenter Server inventory, but the VM's files remain on the datastore. Delete from Disk – this option removes the VM from the inventory and delete its files from the datastore.
To remove the ESX host from VirtualCenter without affecting the running virtual machines you must:
- Right-click the ESX host in the VirtualCenter inventory.
- Choose Disconnect.
- Right-click on the ESX host and select Remove. The ESX host is safely removed from VirtualCenter.
When using the vSphere HTML5 Client to right click a VM folder and select 'Remove from Inventory', virtual machines in the folder are permanently deleted from disk. Unregistering individual virtual machines within a folder continues to work as expected and all files are preserved.
To move an ESXi/ESX host from one vCenter Server to another, remove the host from the vCenter Server then add the host to a new vCenter Server. This operation does not affect the state of any virtual machines running on the ESXi/ESX as long as the prerequisites are met.
Disconnect-VIServerThis cmdlet closes the connection to a vCenter Server system. This cmdlet closes the connection to a vCenter Server system. In PowerCLI, you can have multiple connections to a server. In order to disconnect from a server, you must close all active connections to it.
To delete a virtual machine from the host computer, right-click the name of the virtual machine in the Favorites list and select Delete from Disk; or, select the virtual machine and choose VM > Delete from disk.
Procedure
- In the vSphere Web Client, navigate to the host that you want to remove from a cluster.
- Right-click the host and select Enter Maintenance Mode.
- In the confirmation dialog box that appears, click Yes.
- Right-click the host and select Move To.
- Select a datacenter, folder, or another cluster to move the host to.
