The
HPLeftHandISCSIDriver
is based on the
Block Storage service (Cinder) plug-in architecture. Volume operations
are run by communicating with the HP LeftHand/StoreVirtual system over
HTTPS, or SSH connections. HTTPS communications use the
hplefthandclient,
which is part of the Python standard library.
The
HPLeftHandISCSIDriver
can be configured
to run in one of two possible modes, legacy mode which uses SSH/CLIQ to
communicate with the HP LeftHand/StoreVirtual array, or standard mode
which uses a new REST client to communicate with the array. No new
functionality has been, or will be, supported in legacy mode. For
performance improvements and new functionality, the driver must be
configured for standard mode, the hplefthandclient
must be downloaded, and HP LeftHand/StoreVirtual Operating System
software version 11.5 or
higher is required on the array. To configure
the driver in standard mode, see
the section called “HP LeftHand/StoreVirtual REST driver standard mode”.
To configure the driver in legacy mode, see
the section called “HP LeftHand/StoreVirtual CLIQ driver legacy mode”.
For information about how to manage HP LeftHand/StoreVirtual storage systems, see the HP LeftHand/StoreVirtual user documentation.
