vmhbaAdapter:CChannel:TTarget:LLUN
n
vmhbaAdapter is the name of the storage adapter. The name refers to
the physical adapter on the host, not to the SCSI controller used by the
virtual machines.
n
CChannel is the storage channel number.
Software iSCSI adapters and dependent hardware adapters use the
channel number to show multiple paths to the same target.
n
TTarget is the target number. Target numbering is determined by the
host and might change when the mappings of targets visible to the host
change. Targets that are shared by different hosts might not have the
same target number.
n
LLUN is the LUN number that shows the position of the LUN within the
target. The LUN number is provided by the storage system. If a target
has only one LUN, the LUN number is always zero (0).
For example, vmhba1:C0:T3:L1 represents LUN1 on target 3 accessed
through the storage adapter vmhba1 and channel 0.
Legacy Identifier
In addition to the SCSI INQUIRY or mpx. identifiers, ESXi generates an alternative legacy name for each
device. The identifier has the following format:
vml.number
The legacy identifier includes a series of digits that are unique to the device. The identifier can be derived
in part from the Page 83 information. For nonlocal devices that do not support Page 83 information, the
vml. name is used as the only available unique identifier.
Example: Displaying Device Names in the vSphere CLI
You can use the esxcli --server=server_name storage core device list command to display all
device names in the vSphere CLI. The output is similar to the following example:
# esxcli --server=server_name storage core device list
naa.number
Display Name: DGC Fibre Channel Disk(naa.number)
...
Other UIDs:vml.number
Rename Storage Devices
The ESXi host assigned a display name to a storage device based on the storage type and manufacturer.
You can change the display name of the device.
