I would like to know how can I add a virtual ethernet adapter via command line to a LPAR profile. Would DLPAR work in this case?

Re: add a virtual ethernet adapter via HMC command line2012-12-28T09:29:29Z in response to SystemAdminHi,
For DLPAR use chhwres command :
# chhwres -r virtualio -m CPU-FRM12 -o a --id 101 --rsubtype eth -s 4 -a "ieee_virtual_eth=0,port_vlan_id=131,vswitch=VS_VIO" # chhwres -r virtualio -m CPU-FRM12 -o a --id 101 --rsubtype eth -s 5 -a "ieee_virtual_eth=0,port_vlan_id=132,vswitch=VS_VIO"
Then modify lpar profile with chsyscfg command :
# chsyscfg -m CPU-FRM12-r prof -i 'name=quatest01, lpar_id=101, "virtual_eth_adapters=4/0/131//0/1/VS_VIO,5/0/132//0/1/VS_VIO"
Use man chhwres and man chsyscfg for detailed examples.
Hope this can help
Re: add a virtual ethernet adapter via HMC command line2012-12-28T14:14:19Z in response to SystemAdminHi, thanks for your answer. However, my concern is that currently I have two virtual eth adapters assigned to the LPAR, if I change the profile to add the new adapter, would I lose the two previous ones?
Re: add a virtual ethernet adapter via HMC command line2012-12-28T14:49:53Z in response to SystemAdminTo add and not to erase you current profile add a '+' before the '='
Example with a '+'
chsyscfg -m CPU-FRM12-r prof -i 'name=quatest01, lpar_id=101, "virtual_eth_adapters+=4/0/131//0/1/VS_VIO,5/0/132//0/1/VS_VIO"
Extract for the man :
If '+=' is used in the attribute name/value pair instead of '=', then the specified value is added to the existing value for the attribute if the attribute is numerical. If the attribute is a list, then the specified value(s) is added to the existing list.
For the dlpar chhwres with "-o a" will add an adapter without removing the others.
-o The operation to perform. Valid values are a to add hardware resources, r to remove hardware resources, m to move hardware resources from one partition to another, s to set hardware resource related attributes, rs to reset I/O entitled memory statistics for a partition, so to switch over a running shared memory partition to its redundant paging VIOS partition, or c to clear a physical I/O slot or bus. The c operation is useful for clearing stale physical I/O slot or bus information after a physical I/O adapter or drawer has been concurrently removed but not replaced. The clear physical I/O slot operation is only supported on POWER6 and later servers.
Hope this can help.
