The AIX Logical Volume Manager (LVM) manages Logical Volumes (LVs) that Assure MIMIX for AIX protects.
Because Assure MIMIX for AIX manages Logical Volumes, not all the AIX LVM commands are supported. The table below shows the LVM commands supported when the Assure MIMIX for AIX drivers are loaded.
