We recently added two 10Gb OSA cards to our Z9 to replace our old 1Gb
cards. I'm trying to figure out how to convert from the old cards to the
new (zVM 5.4), while having an easy backout method.
SYSTEM CONFIG has these statements
DEFINE VSWITCH VSWITCH1 RDEV 1E08 CONN CONTROLLER *
DEFINE VSWITCH VSWITCH2 RDEV 1F08 CONN CONTROLLER *
MODIFY VSWITCH VSWITCH1 GRANT TCPIP
MODIFY VSWITCH VSWITCH2 GRANT TCPIP
DEFINE LAN LINUXLAN OWNER SYSTEM TYPE QDIO
Apparently because of the 'CONTROLLER *' CP gets to decide who controls t
he
device(s). They're not attached to TCPIP.
q 1e08-1e0a
OSA 1E08 ATTACHED TO DTCVSW2 1E08 DEVTYPE OSA CHPID F9 OSD
OSA 1E09 ATTACHED TO DTCVSW2 1E09 DEVTYPE OSA CHPID F9 OSD
OSA 1E0A ATTACHED TO DTCVSW2 1E0A DEVTYPE OSA CHPID F9 OSD
q 1f08-1f0a
OSA 1F08 ATTACHED TO DTCVSW2 1F08 DEVTYPE OSA CHPID FD OSD
OSA 1F09 ATTACHED TO DTCVSW2 1F09 DEVTYPE OSA CHPID FD OSD
OSA 1F0A ATTACHED TO DTCVSW2 1F0A DEVTYPE OSA CHPID FD OSD
In AUTOLOG2's PROFILE EXEC, the DTCVSW1 and DTCVSW2 get started before
TCPIP.
Not that it makes any difference - we have connectivity - but is this the
normal way to set up VSwitch?
Besides SYSTEM CONFIG, there are references in the USER DIRECT entry for
TCPIP

In sysname TCPIP there's a reference in a few places:

DEVICE VSW1F08 OSD 1F08 PORTNAME DEVVSW2 SecRouter

010.008.185.001 GLNB010L
START VSW1E08
START VSW1F08
START GLNB010
And in MPROUTE CONFIG:
OSPF_Interface
IP_Address=10.8.128.14
Attaches_To_Area=0.0.0.2
Name=VSW1E08L
Hello_Interval=5
... more stuff
OSPF_Interface

Attaches_To_Area=0.0.0.2
Name=VSW1F08L
... more stuff
Interface
IP_Address=10.8.190.2
Name=OSAV
-----------------------------------------------------------------------
The new OSA cards are addresses 2708-270A and 2F08-2F0A
This is my guess of what I should do, but it's just that; a guess. I'd
like to hear the right way to go about this with minimal outage/impact an
d
maximum safety/backout-ability.
If I want to test the 2708 OSA card, I could
Update sysname TCPIP to change the 1E08 address and names to 2708
Update MPROUTE CONFIG to change the link name to match
Update TCPIP user direct entry to change the nicdef from 1E08 to 2708
Enter CP commands from console
FORCE TCPIP
SET VSWITCH VSWITCH1 RDEV 2708
(maybe set mdcache system off? That's gotten me in the past)
AUTOLOG TCPIP
Use TCPMAINT to NETSTAT DEV and look for bytes in/out
Assuming there is traffic on the new OSA, repeat the process for the
1F08/2F08
Update SYSTEM CONFIG to change the VSWITCH info and run CPSYNTAX
Thanks for any and all advice.
