Functions available on pluggable and integrated storage drivers
PowerVC supports the use of integrated storage drivers as well as pluggable storage drivers. However, due to the nature of pluggable storage drivers, there are some differences in available functionality. Issues traced back to a pluggable driver or underlying device will be referred to the device vendor.
