If you detect a failed storage device or if you upgrade a device, you can manually remove it from a host by using an ESXCLI command.
Before you begin
Verify that the storage controllers on the hosts are configured in passthrough mode and support the hot-plug feature.
If the storage controllers are configured in RAID 0 mode, see the vendor documentation for information about adding and removing devices.
About this task
If you remove a flash caching device, vSAN deletes the disk group that is associated with the flash device and all its member devices.
- Open an SSH connection to the ESXi host.
- To identify the device ID of the failed device, run this command and learn the device ID from the output.
esxcli vsan storage list
- To remove the device from vSAN, run this command.
esxcli vsan storage remove -d device_id
What to do next
Add a new device to the host.
The host automatically detects the device.
If the host is unable to detect the device, perform a device rescan.
