Hello 3PAR experts. I am an EMC Storage Admin that has been asked to work with a 3PAR T800. I have next to know experience with 3PAR. I attempted to create a 750GB VLUN for a 3 node ESX cluster. I used the createvv and createvlun commands. However what I did was create 3 seperate 750GB LUNs. What are the commands to create a LUN for a 2 or 3 node server?

Also how do I remove 2 of the 750GB VLUNS and get all 3 of the ESX servers to see one 750GB LUN.

Thank you experts.

While I have no knowledge of ESX cluster, I suppose you are trying to give 3 servers access to the same volume?!
If so, you need to create only one volume (createvv). Then you present this volumes to all three hosts (createvlun). I would suggest you create a hostset (createhostset) containing all three hosts and present the volume to the hostset (createvlun volume_name auto set:hostset_name).

To remove the superfluous volumes use removevv.

Good luck :)

ESX best practice is for the VV to be the same LUN # on all 3 hosts as well.

Do the createvv once, do the createvlun 3 times. A VV or virtual volume is the equivalent to a metavolume, and a VLUN is equivalent to "masking/unmasking" in emc terms.

Hope that helps.
