The storage pool represents the amount of capacity provided by the host to the vSAN datastore.
Each host's storage devices claimed by vSAN form a storage pool. All storge devices claimed by vSAN contribute to capacity and performance.
Prerequisites
-
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.
- If you upgrade the storage pool device, verify that the cluster contains enough space to migrate the data from the storage pool device.
Procedure
- Navigate to the vSAN cluster.
- On the Configure tab, click Disk Management under vSAN.
- Select the storage pool device, and click Remove Disk.
- In the Remove Disk dialog box, select Full data migration to transfer all the data available on the host to other hosts in the cluster.
- Click Go To Pre-Check to find the impact on the cluster if the object is removed or placed in maintenance mode.
- Click Remove to remove the storage pool device.
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.
- Claim a disk using the vSAN cluster > Configure > vSAN > Disk Management.
