In iplugin.py, i don't see support for snapshot API for ISAN
class... tho' the fs_snapshot is present for INAS.
For IBM V7k, which is of SAN type, it does support snapshots and I
wanted to know if I can introduce something like
and the likes..kind of APIs for ISAN ?
If no, then how do i support snapshots for v7k ?

The volume_replicate method takes an enumerated type of replication.
(REPLICATE_UNKNOWN, REPLICATE_SNAPSHOT, REPLICATE_CLONE, REPLICATE_COPY,
REPLICATE_MIRROR_SYNC, REPLICATE_MIRROR_ASYNC) = \
(-1, 1, 2, 3, 4, 5)
In libStorageMgmt terms a snapshot is a point in time space efficient
read-only copy. Does this match what the V7K supports? Otherwise if it
is a space efficient read/writable it is a clone.
The reason the two have slightly different API's is that in the case of
a file system you can snapshot the entire file system or in some cases
individual file(s) on a file system.
