2.4.3. The Command lpar

All PowerVM functions that affect an LPAR can be carried out with the lpar command. The LPAR tool covers the following areas of LPAR administration, among others:

    • Activate and deactivate of LPARs
    • Access to the console of an LPAR
    • Administration of virtual adapters (serial, Ethernet, FC, SCSI, SR-IOV, vNIC)
    • Administration of memory and processors
    • Creation and deletion of LPARs
    • View performance data
    • Live Partition Mobility (validation and migration)
    • Manage partition profiles

An overview of the available functions is displayed when the lpar command is started without arguments:

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