Understanding Storage Device Naming
Runtime Name
The name of the 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. Since there are 4 entries,
there are 4 paths. [A above]
With both active/active and active/passive storage arrays, you can set up your host to use
different paths to different LUNs so that your adapters are being used evenly. Since the
Status shows Active for the first entry and Passive for the remainder, the LUN is on an
Active/Passive array. [B is correct, and therefore E is incorrect.]
Active/passive arrays use the MRU path policy which does not have a preferred path.
Therefore C is incorrect.
Runtime Name – The name of the first path to the device. Since the Runtime Name is
vmhba3:0:0 (from the top of the dialog box), and the active device is vmhba2:2:0 then it
can be assumed that an HBA Failover occurred. Therefore D is correct.
