The VSANs that are assigned to this session.
Each octet within the value of this object specifies
a set of eight VSANS with the first octet specifying
VSAN 1 through 8, the second octet specifying VSAN 9
through 16, etc. Since there are 256 octets, the range
of VSANs is from 0-2047. Within each octet, the most
significant bit represents the lowest numbered VSAN id
and the least significant bit represents the highest
numbered VSAN id. Thus each VSAN is represented by a single
bit within the value of this object. If that bit has value
'1' then that VSAN is included in the set of VSANs; the
VSAN is not included if its bit has a value of '0'.
