P2000 G3 with dual controller - question PortA and PortB

[AlejandroK]

Hi All,

sorry my english.. :)

Problem: Explicit Volume Mapping

I have a P2000 G3 FC storage connected to one server with dual HBA.

My question is that when I set in two volumes P2000 doubles disks on the server.

Hi

You need to install multipathing software on the server, you can use the windows native MPIO to fix this issue

follow the instruction on the below link

Hi, msh_it

Is not necesary Host Group definition on Storage (P2000)?

I make this on ibm storage (ds3400) or emc.

Hi,

The continuous problem. The multipath doesn't work and shows duplicate disks.

This happens to me with Windows 2012 STD, in Windows 2012R2 I had no problem.

Best regards.
