When you make changes in your SAN configuration, you might need to rescan your storage. You can rescan all storage available to your host, cluster, or data center. If the changes you make are isolated to storage accessed through a specific host, perform the rescan for only this host.

Procedure

  1. In the vSphere Web Client object navigator, browse to a host, a cluster, a data center, or a folder that contains hosts.
  2. From the right-click menu, select Storage > Rescan Storage .
  3. Specify extent of rescan.
