vSphere StoragevmhbaAdapter:CChannel:TTarget:LLUN• vmhbaAdapter is the name of the storage adapter. The name refers to thephysical adapter on the host, not to the SCSI controller used by thevirtual machines.• CChannel is the storage channel number.Software iSCSI adapters and dependent hardware adapters use thechannel number to show multiple paths to the same target.• TTarget is the target number. Target numbering is determined by thehost and might change if the mappings of targets visible to the hostchange. Targets that are shared by different hosts might not have thesame target number.• LLUN is the LUN number that shows the position of the LUN within thetarget. The LUN number is provided by the storage system. If a targethas only one LUN, the LUN number is always zero (0).For example, vmhba1:C0:T3:L1 represents LUN1 on target 3 accessed throughthe storage adapter vmhba1 and channel 0.Legacy IdentifierIn addition to the SCSI INQUIRY or mpx. identifiers, for each device, ESXi generates an alternative legacyname. The identifier has the following format:vml.numberThe legacy identifier includes a series of digits that are unique to the device and can be derived in part fromthe Page 83 information, if it is available. For nonlocal devices that do not support Page 83 information, thevml. name is used as the only available unique identifier.Example: Displaying Device Names in the vSphere CLIYou can use the esxcli --server=server_name storage core device list command to display all devicenames in the vSphere CLI. The output is similar to the following example:# esxcli --server=server_name storage core device listnaa.numberDisplay Name: DGC Fibre Channel Disk(naa.number)...Other UIDs:vml.numberRename Storage DevicesYou can change the display name of a storage device. The display name is assigned by the ESXi host basedon the storage type and manufacturer.Procedure1 Browse to the host in the vSphere Web Client navigator.2 Click the Manage tab, and click Storage.3 Click Storage Devices.4 Select the device to rename and click Rename.5 Change the device name to a friendly name.122 VMware, Inc.
