How Do You Configure a 2nd VSWITCH?
We currently have a functioning VSWITCH, LNXVSW1, related to a VSWITCH controller, DTCVSW2 at OSA 9004. Q VSWITCH 09:14:01 VSWITCH SYSTEM LNXVSW1 Type: VSWITCH Connected: 3Maxconn: INFINITE 09:14:01 PERSISTENT RESTRICTEDNONROUTER Accounting: OFF 09:14:01 VLAN Unaware 09:14:01 MAC address: 02-00-00-00-00-01 09:14:01 State: Ready 09:14:01 IPTimeout: 5 QueueStorage: 8 09:14:01 RDEV: 9004.P00 VDEV: 9004 Controller: DTCVSW2 We are trying to understand how LNXVSW1 is related to the VSWITCH controller, DTCVSW2 so that we can configure a second VSWITCH, LNXVSW2, for redundancy and improved throughput. We believe it is related through our DEFINE in SYSTEM CONFIG: /* vswitch definitions*/ define vswitch lnxvsw1 portname lnxvsw1 rdev 9004 /* end of vswitch definition */ and our subsequent OSA ATTACH of 9004 to DTCVSW2: Q OSA 09:14:46 OSA 9000 ATTACHED TO TCPIP9000 DEVTYPE OSA CHPID D4 OSD 09:14:46 OSA 9001 ATTACHED TO TCPIP9001 DEVTYPE OSA CHPID D4 OSD 09:14:46 OSA 9002 ATTACHED TO TCPIP9002 DEVTYPE OSA CHPID D4 OSD 09:14:46 OSA 9004 ATTACHED TO DTCVSW2 9004 DEVTYPE OSA CHPID D4 OSD 09:14:46 OSA 9005 ATTACHED TO DTCVSW2 9005 DEVTYPE OSA CHPID D4 OSD 09:14:46 OSA 9006 ATTACHED TO DTCVSW2 9006 DEVTYPE OSA CHPID D4 OSD 09:14:46 OSA 903F ATTACHED TO SY92TEST 902F DEVTYPE OSA CHPID 0B OSD 09:14:46 OSA 907F ATTACHED TO SY91TEST 906F DEVTYPE OSA CHPID 0F OSD 09:14:46 OSA 90D0 ATTACHED TO VTAM 90D0 DEVTYPE OSA CHPID D1 OSE 09:14:46 OSA 9100 ATTACHED TO TCPIP9100 DEVTYPE OSA CHPID D5 OSD 09:14:46 OSA 9101 ATTACHED TO TCPIP9101 DEVTYPE OSA CHPID D5 OSD Is this correct? If so, then to configure a second VSWITCH, we should be able to DEFINE a second VSWITCH, LNXVSW2, in SYSTEM CONFIG as 9005 and ATTACH the OSA 9005 TO DTCVSW1. Is this correct?
Re: How Do You Configure a 2nd VSWITCH?
If you have supporting hardware, you can potentially get better throughput with link aggregation. But, using your method just define the new Vswitch. You do not need to 'attach' anything, CP handles the device mechanics. Depending upon how much traffic you are pumping through the OSA on D4 you may want to pick a different OSA CHPID. These are some of the things that should be determined with monitoring.

(Another PORTNAME bites the dust!) and our subsequent OSA ATTACH of 9004 to DTCVSW2: Is this correct? No. You don't ATTACH or DETACH anything; the system handles it. Just DEFINE VSWITCH. If so, then to configure a second VSWITCH, we should be able to DEFINE a second VSWITCH, LNXVSW2, in SYSTEM CONFIG as 9005 and ATTACH the OSA 9005 TO DTCVSW1. Is this correct? No. Just defines your second (third, fourth, ...) VSWITCH and don't worry about controller selection. The only time to worry about the controller is when the Support Center asks you to do it.

Re: How Do You Configure a 2nd VSWITCH?
Dear George, I see in your 'Query OSA' that the address 9005 is now attached to DTCVSW2. If you need a second VSWITCH, you must use a free OSA-Address (maybe 9007 is free). You can dynamically define your VSWITCH (e.g. in Userid Maint) and attatch him to your Linux-System, before you put this in your System Config. Best is, you make your definitions in the profile exec of your VM-User Autolog1 instead of System Config.
