SAN zoning scenarios when components failed based on IBM Pureflex system, dual VIOS, NPIV, FC switches and V7000 storage.

Working on a fully IBM environment for some years,I asked to my self, whet happens with zoning of my LPARs if I lost a vioserver, a FC switch, or a controler (node) on the storage system.
You will find here, examples of these scenarios on a IBM pureflex system and a V7000 storage system.

On every scenario you will find information for:
1- LPAR virtual FC adapters, WWNs, and WWNs for live partition mobility. 
2- VIOServers with their VFCHOST, fcs0 and fcs1 adapters.
3- Cable connection between ports on every VIOserver and FC switches
   on the pureflex chassis.
4- Ports used,  active zones, on every switches.
5- Cable connection between FCswitches and the storage, ports used
   on the nodes, active WWNs
   on controlers (nodes) on V7000 system.

We’ll start with system stable with all zoning working fine.

Scenario1
Zoning on the system when VIOS1 failed.
See image below:
optimal zonning-fail-vios1

Scenario2
Zoning on the system when VIOS2 failed.
See image below:
optimal zonning-fail-vios2

Scenario3
Zoning on the system when FCswitch1 failed.
See image below:
optimal zonning-fail-switchFC1

Scenario4
Zoning on the system when FCswitch2 failed.
See image below:
optimal zonning-fail-switchFC2

Scenario5
Zoning on the system when VIOS1 and FCswitch1 failed.
See image below:
optimal zonning-fail-vios1-switch1

Scenario7
Zoning on the system when VIOS2 and FCswitch2 failed.
See image below:
optimal zonning-fail-vios2-switch2-nodeleft2

Scenario8
Zoning on the system when VIOS1, FCswitch1 and nodeleft (controler) failed.
See image below:
optimal zonning-fail-vios1-switch1-nodeleft1

Scenario9
Zoning on the system when VIOS2, FCswitch2 and noderight (controler) failed.
See image below:
optimal zonning-fail-vios2-switch2-nodeleft2

I know there’re other scenarios, but I think with all these examples it’s enough.

Hope this helps.

Just thanks if the post was helpful 🙂
