Operating Systems AIX AIX LPAR FC connection to SAN Post 303031470 by Phat on Friday 1st of March 2019 04:27:21 AM

Hi Bakunin,

Take a look on first lpar, we can see the virtual fiber, it comes from VIOS and routed to physical FC of Power machine.
Code:
[root@xxx] / > lsdev -Cc adapter | grep fcs
fcs0 Available 12-T1 Virtual Fibre Channel Client Adapter
fcs1 Available 12-T1 Virtual Fibre Channel Client Adapter
fcs2 Available 12-T1 Virtual Fibre Channel Client Adapter
fcs3 Available 12-T1 Virtual Fibre Channel Client Adapter

Take a look on second lpar, it's not virtual. I wonder if it is actual physical FC from Power Machine assigned directly to lpar.
Code:
[root@zzz] / > lsdev -Cc adapter | grep fcs
fcs0 Available 00-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs1 Available 00-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs2 Available 01-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs3 Available 01-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs4 Available 05-00 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)
fcs5 Available 05-01 8Gb PCI Express Dual Port FC Adapter (df1000f114108a03)

I wonder where those physical FC come from? As virtual FC comes from VIOS.
