I have noticed something called Runtime Name. I have tried to figure out what that means but without luck.
Runtime Name - The name of the first path to the device. The runtime name is created by the host. The name is not a reliable identifier for the device, and is not persistent. The runtime name has the following format:
vmhba# 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.
C# is the storage channel number.
T# is the target number. Target numbering is decided by the host and might change if there is a change in the mappings of targets visible to the host. Targets that are shared by different hosts might not have the same target
L# 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).
Can anyone explain what vmhba2:C0:T3:L0 means?
vmhba2:C0:T3:L0 represents LUN0 on target 3 accessed through the storage adapter vmhba2 and channel 0.
All of this information was taken directly from the Fibre Channel SAN Configuration Guide.
TTarget is the target number. Target numbering is determined by the host and might change if the mappings of targets visible to the host change. Targets that are shared by different hosts might not have the same target number.
