| Description | The zoneSetZoneList object and the
zoneSetZoneListTable allow upto 8192
zones to be associated with a zoneset.
This is done with the help of 4 bitmaps
each of which represent 2048 zones. There
may exist a situation where the 'lowest'
bitmap may not be fully populated but
'higher' bitmaps may have bits set in them.
Semantically what this means is: the lowest
2048 zones have not been fully associated,
but zones with higher ids have been
associated. This kind of a situation causes
problems for management stations which are
only aware of older versions of this MIB. They
are only aware of zoneSetZoneList object and
hence only the 'lowest' 2048 zones that are
associated with a zoneset. In the above
situation, the total number of zones
associated with the zoneset could be less
than 2048. But by virtue of being distributed
in the 'higher' bitmaps, those zones will
not be seen by those management stations as
they are not aware of the new objects in
zoneSetZoneListTable. In such a situation,
a management station which is aware of this
version of the MIB, can choose to compact
the zones associated with zonesets on a
VSAN, so that the holes in the lowest 2048
zones are filled.
Note that this table facilitates compaction
of only the first 2048 zones and not zones
belonging to 'higher' bitmaps. |
