PowerVM VIOS

To list all network mapping :
# lsmap –all –net


To list SEA and physical device mapped to virtual Ethernet Adapter ent4 :
# lsmap -vadapter ent4 –net

Manual SEA Failover
On VIO server:
$ lsdev -type adapter
or
$ oem_setup_env
# lsdev -Cc adapter |grep ent --> Note which ent is the SEA
# entstat -d entX | grep State --> Check for the state (PRIMARY, or BACKUP)

Set ha_mode to standby on primary VIOS with chdev command:
# chdev -l entX -a ha_mode=standby
or
$ chdev -dev -attr ha_mode=standby

Reset it back to auto and the SEA should fail back to the primary VIOS:
# chdev -l entX -a ha_mode=auto
or
$ chdev -dev -attr ha_mode=auto
