Duplicate targets in HP 11.0

[Michael_556]

Hi

We have HP 11.0.
When we connect it to our target device which has one disk LUN configured for the HP,
Sometimes the HP "sees" this specific LUN 16 times as it has 16 different targets instead of one.

Here is an output of the HP :

Have you encountered such a problem before?
Do you know what is the solution for it?
Is the problem in the HP side or in the Target device?

Thanks,
Michael

Hi Micheal,
It looks like problem in ZONING. May be the zoning info on the switch is getting modified. You need to check whether it is done properly.
What HP see's is correct. This are all different LUN devices connected to controller instance no. 22.
So i don't think this is problem on HP - BOX.

Check ZONING/LUNMASKING configuration on your switch.

Hi

We do not have any zoning or LUN masking modifications.
We have the HP server and our target device, each connected with one port.
