vSwitch sanity check question

[RPN01]

I have a production vSwitch with a back-up OSA, and I¹d like to take out the
back-up OSA for a moment and test it separately from its normal vSwitch.

If I redefine a vSwitch on the fly, will it go ³down² for any amount of time
while reconfiguring? Or for that matter, can I even do a DEFINE command for
a currently active vSwitch at all?

My current definition looks like this:

q vswitch vswg
VSWITCH SYSTEM VSWG Type: VSWITCH Connected: 36   Maxconn: INFINITE
PERSISTENT  RESTRICTEDPRIROUTER Accounting: OFF
VLAN Unaware
MAC address: 02-00-00-00-00-01
State: Ready
IPTimeout: 5 QueueStorage: 8
Portname: OSASUE2RDEV: 8A00 Controller: DTCVSW1  VDEV:  8A00
RDEV: 8B00 VDEV: 8B00 Controller: DTCVSW2  BACKUP
Ready; T=0.01/0.01 14:31:53

Could I issue the command ³CP DEFINE VSWITCH VSWG RDEV 8A00 IP PRIROUTER²
without disrupting the current traffic on the vSwitch?

In theory, theory and practice are the same, but
 in practice, theory and practice are different.

Not DEFINE, but SET.  Issue the SET VSWITCH RDEV with only the active 
device.  To add it back, issue the command again with both devices.
