How to find 3PAR vlun WWNs(virtual Lun WWNs)

We have come across many situations, where we have been asked to work on SAN storage issues and we had only 3PAR lun WWNs to start the troubleshooting. Through IMC it is really tough to identify the vlun WWNs and we have to relay on IMC CLI or PuTTY connections. Let's see how can we identify the vlun with lun WWN.

To start with, we have to execute a  3PAR-CLI commands and work with the output.The command which we tried is showvlun (Along with some special OPTIONS are used)

. I have tried the combination of showvlun and -lvw   (Show the WWN of the virtual volume associated with the VLUN.)

The output resulted as shown below.

Once you have the detailed lun information, you can export the output to excel sheet and search for virtual volumes and you can obtain the vlun details.
