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. 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'.
