Manage local and networked storage device that your ESXi host has access to. Storage Device CharacteristicsWhen your ESXi host connects to block-based storage systems, LUNs or storage devices that support ESXi become available to the host. You can display all storage devices, including all local and networked devices. If you use third-party multipathing plug-ins, the storage devices available through the plug-ins also appear on the list. Understanding Storage Device NamingEach storage device, or LUN, is identified by several names. Storage Rescan Operations When you perform storage management tasks or make changes in the SAN configuration, you might need to rescan your storage. Identifying Device Connectivity ProblemsWhen your ESXi host experiences a problem while connecting to a storage device, the host treats the problem as permanent or temporary depending on certain factors. Edit Configuration File ParametersYou can change or add virtual machine configuration parameters when instructed by a VMware technical support representative, or if you see VMware documentation that instructs you to add or change a parameter to fix a problem with your system. Enable or Disable the Locator LED on Storage DevicesUse the locator LED to identify specific storage devices, so that you can locate them among other devices. You can turn the locator LED on or off. Erase Storage DevicesCertain functionalities, such as vSAN or virtual flash resource, require that you use clean devices. You can erase an HHD or flash device and remove all existing data.
