I have a double fabric built by 3 Brocade switches (core-edge topology).
The double fabric is well operating since many years.
Now I have to enable in the core switch the “WWN Based persistent PID” because an AIX server (it can boot from EMC VMAX storage very well) have to migrate to new EMC Unity 400F. I have discovered the AIX server cannot boot from EMC Unity, so I have to enable the WWN Based persistent PID (this is an EMC best practice) in the core switch.
The question is: do I have to enable the “WWN Based persistent PID” in the edge switches, too?
Here below the details of my configuration.
The core switch is Brocade 6510 (FOS 7.4.1d).
The edge switches are IBM FC5022 (OEM Brocade 6547, FOS 7.4.1.c).
The core switch and the edge switches are linked by double ISL connection (no trunk).
The disk storages, the tape libraries, the AIX servers are connected to the core switch.
Lots of ESX servers are connected to edge switches. The ESX servers are IBM Flex System blades.
Please, have a look the atteched picture.
Thanks a lot
