====== VIOS dynamically add a VLAN ======

This function is available using Web interface https://www.ibm.com/support/pages/how-add-or-modify-additional-vlans-using-enhanced-ui

Or here describe the hmc command line

===== Precheck before adding =====

Check RMC connection --> it's required ! If inactive follow the procedure from wiki
<cli prompt='>'>
hscroot@hmc01:~> for srv in $(lssyscfg -r sys -F name); do lssyscfg -r lpar -m $srv -F name,rmc_state ; done | grep vios
...
vios01,active
vios02,active
</cli>

Check the profiles synchronization for all LPARs
<cli prompt='>'>
hscroot@hmc01:~> for srv in $(lssyscfg -r sys -F name); do lssyscfg -r lpar -m $srv -F name,sync_curr_profile ; done
lnxa087,2
aixa003,1
...
vios01,1
vios02,1
</cli>

If value not equal to 1 --> synchronize the profile, go on HMC web, on the partition property select advanced and in the section "Save configuration changes to profile", change to "Enabled" and save. Recheck using command line


===== Adding a VLAN =====

Add a new VLAN vlanid: 112, on the server power9-002

:!: ATTENTION !!! check which slot is used by SEA, here **slot 33** on vios01, and **slot 2** on vios02

Only on VLAN per line
