vSphere Storage 2 Select a rescan option. Option Description Storage In the Hardware panel, click Storage, and click Rescan All above the Datastores or Devices panel. Storage Adapters In the Hardware panel, click Storage Adapters, and click Rescan All above the Storage Adapters panel. 3 Specify extent of rescan. Option Description NOTE You can also right-click an individual adapter and select Rescan to rescan just that adapter. Scan for New Storage Devices Rescan all adapters to discover new storage devices. If new devices are discovered, they appear in the device list. Scan for New VMFS Volumes Rescan all storage devices to discover new datastores that have been added since the last scan. Any new datastores appear in the datastore list. Perform Storage Rescan in the vSphere Web Client 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 datacenter. If the changes you make are isolated to storage accessed through a specific host, perform rescan for only this host. Procedure 1 In the vSphere Web Client object navigator, select a host, a cluster, a datacenter, or a folder that contains hosts. 2 Select Actions > All vCenter Actions > Rescan Storage. 3 Specify extent of rescan. Option Description Scan for New Storage Devices Rescan all adapters to discover new storage devices. If new devices are discovered, they appear in the device list. Scan for New VMFS Volumes Rescan all storage devices to discover new datastores that have been added since the last scan. Any new datastores appear in the datastore list. Perform Adapter Rescan in the vSphere Web Client When you make changes in your SAN configuration and these changes are isolated to storage accessed through a specific adapter, perform rescan for only this adapter. Procedure 1 Browse to the host in the vSphere Web Client navigator. 2 Click the Manage tab, and click Storage. 3 Click Storage Adapters, and select the adapter to rescan from the list. 4 Click Rescan Adapter. 136 VMware, Inc.
Change the Number of Scanned LUNs By default, the VMkernel scans for LUN 0 to LUN 255 for every target (a total of 256 LUNs). You can modify the Disk.MaxLUN parameter to improve LUN discovery speed. IMPORTANT You cannot discover LUNs with a LUN ID number that is greater than 255. Reducing the value can shorten rescan time and boot time. However, the time to rescan LUNs might depend on other factors, including the type of storage system and whether sparse LUN support is enabled. Procedure 1 In the vSphere Client inventory panel, select the host, click the Configuration tab, and click Advanced Settings under Software. 2 Select Disk. 3 Scroll down to Disk.MaxLUN. 4 Change the existing value to the value of your choice, and click OK. The value you enter specifies the LUN after the last one you want to discover. For example, to discover LUNs from 0 through 31, set Disk.MaxLUN to 32.
