HP-UX vPars and Integrity VM V6.3 Administrator Guide

The following example uses the hpvmnet command to halt the vswitch and then to delete it. Both
the commands require you to confirm the action.
# hpvmnet -S clan1 -h
hpvmnet: Halt the vswitch 'clan1'? [n/y]: y
# hpvmnet -S clan1 -d
hpvmnet: Remove the vswitch 'clan1'? [n/y] y
The default command function (if you press Enter) is to not perform the function of the command.
To perform the command function, enter y.
In the case of commands where a confirmation is required, such as the hpvmnet -h command,
you can include the —Q option to override the confirmation process. This is useful in scripts and
processes that are not interactive. For example, to stop a vswitch (clan1) without requiring
confirmation from the user, enter the following commands:
# hpvmnet
Name Number State Mode NamePPA MAC Address IP Address
======== ====== ======= ========= ======== ============== ===============
localnet 1 Up Shared N/A N/A
clan1 2 Up Shared lan0 0x00306e39f70b
# hpvmnet -S clan1 -h -Q
# hpvmnet
Name Number State Mode NamePPA MAC Address IP Address
======== ====== ======= ========= ======== ============== ===============
localnet 1 Up Shared N/A N/A
clan1 2 Down Shared lan0
When an active vswitch is deleted, the VSP automatically determines that the vswitch is gone.
When the vswitch is recreated, the guest network automatically becomes functional.
8.2.1.5 Recreating vswitches
To change the vswitch to use another pNIC on the VSP (for example, to change from lan0 to
lan1),
1. Delete the vswitch associated with lan0. For example,
# hpvmnet -S myswitch -h -Q
# hpvmnet -S myswitch -d
2. Create a new vswitch associated with lan1. For example,
# hpvmnet -S myswitch -c -n 1
3. Add a new vNIC to your guest using the new vswitch. For example,
# hpvmmodify -P guestname -a network:avio_lan:,,:vswitch:myswitch
8.2.1.6 Starting vswitches
Virtual switches (vswitches) start automatically when the VSP system is started. You can start the
vswitch manually using the —b option with the hpvmnet command. For example, the following
command boots the vswitch named clan1:
# hpvmnet -S clan1 -b
