2nd fibre channel need and configure alternate link
Currently, we do have one Hitachi Storage system and one hp rx7600 with HP-UX 11.23 version. At the moment, only one fc adapter (HP Tachyon XL2 Fibre Channel Mass Storage Adapter)was installed in rx7600.
In order to create a redundancy link to HDS, we prepare a create a HDD alternate link by plug into addition fc into system.
As my concern, how can i make it happen with the minimum risks on it. Of course, i know i have to create the alternate HDD link one by one after the fc adapter is installed in rx7600.
Is anyone do this before?

Re: 2nd fibre channel need and configure alternate link
once the HBA is installed and connected, you may run "vgscan" in preview mode to get an idea.
Hope this helps!

Re: 2nd fibre channel need and configure alternate link
The "old" device files will not change.
The system will create another path to the existing LUNs only.
Hope this helps!
