Zone And Zoneset Analysis - Cisco MDS 9000 Series Configuration Manual

Zone and ZoneSet Analysis

cause you to lose the zones over the limit. To avoid the configuration check, delete the excess zones and
compact the zone database for the VSAN. If there are 8000 zones or fewer after deleting the excess zones,
the compacting process assigns new internal zone IDs and the configuration can be supported by Cisco
SAN-OS Release 6.2(5) or earlier. Perform this procedure for every VSAN on the switch with more than
8000 zones.
Note A merge failure occurs when a switch supports more than 8000 zones per VSAN but its neighbor does not.
Also, zoneset activation can fail if the switch has more than 8000 zones per VSAN and not all switches in the
fabric support more than 8000 zones per VSAN.
To delete zones and compact the zone database for a VSAN, follow these steps:
Step 1 switch# configure terminal
Enters configuration mode.
Step 2 switch(config)# no zone name ExtraZone vsan 10
Deletes a zone to reduce the number of zones to 8000 or fewer.
Step 3
switch(config)# zone compact vsan 10
Compacts the zone database for VSAN 10 to recover the zone ID released when a zone was deleted.
To compact the zone database for downgrading, refer to the
Zone and ZoneSet Analysis
To better manage the zones and zone sets on your switch, you can display zone and zoneset information using
the show zone analysis command.
