2.4.4. The Command vios

The virtualization functions of the virtual I/O server can be administered with the vios (virtual I/O server) command. A direct login on the virtual I/O servers is not required. An active RMC connection between the virtual I/O server and the associated HMCs is sufficient.

    • In particular, the following PowerVM functionalities of a virtual I/O server can be administered:
    • Shared Ethernet Adapter (SEA)
    • NPIV mappings
    • SCSI mappings
    • Virtual Optical Media Repository
    • Storage Pools
    • Link Aggregations
    • Device management (display and setting of attributes)

Here, too, you can get a complete overview of the supported functions by starting the vios command without arguments:

$ vios
vios [ ...] [ ...] [ ...]vios -L|-V
