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

  1. Navigate to the vSAN cluster.
  2. On the Configure tab, click Disk Management under vSAN.
  3. Select the storage pool device, and click Remove Disk.
  4. 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.
  5. Click Go To Pre-Check to find the impact on the cluster if the object is removed or placed in maintenance mode.
  6. Click Remove to remove the storage pool device.

What to do next

  1. Add a new device to the host.

    The host automatically detects the device.

  2. If the host is unable to detect the device, perform a device rescan.
  3. Claim a disk using the vSAN cluster > Configure > vSAN > Disk Management.
