Some advanced functions of the HP MA and EMA are not supported by the Lenovo Storage V series system.
Advanced copy functions
Advanced copy functions for HP MA and EMA systems (for example, SnapShot and RemoteCopy) are not
supported for disks that are managed by the Lenovo Storage V series system because the copy function does
not extend to the Lenovo Storage V series cache.
Partitioning
HP MA and EMA support partitioning.
A partition is a logical division of a container that is represented
to the host as a logical unit (LU). A container
can be an array or a JBOD (just a bunch of disks). All container
types are candidates for partitions. Any nontransportable disk or
storage set can be divided into a maximum of eight partitions.
The
following restrictions apply to partitioning:
- Partitioned
containers are fully supported if the HSG80 controller
is connected to the SAN by a single port.
- Partitioned containers are not configured by the Lenovo Storage V series system if the HSG80 controller is
connected to the SAN by multiple ports.
- Partitioned
containers are removed from the configuration if a
single port connection becomes a multiport connection.
- Partitioned
containers are configured if a multiport connection
becomes a single port connection.
You must partition containers
such that no spare capacity exists
because there is no way to detect unused partitions. With a multiport
connection, subsequent attempts to use this capacity removes all partitions
on the container from the configuration.
Dynamic
array expansion (LU expansion)
HP
MA and EMA systems do not provide dynamic array expansion.
Write protection of LUNs
Write protection of LUNs is not supported for use with the Lenovo Storage V series system.
