Chapter 30 Configuring and Managing Zones Compacting the Zone Database for Downgrading Send documentation comments to [email protected] Figure 30-44 Zone Merge Analysis Dialog Box Step 2 Step 3 Step 4 Step 5 Step 6 Select the first switch to be analyzed from the Check Switch 1 drop-down list. Select the second switch to be analyzed from the And Switch 2 drop-down list. Enter the VSAN ID where the zone set merge failure occurred in the For Active Zoneset Merge Problems in VSAN Id field. Click Analyze to analyze the zone merge. Click Clear to clear the analysis data in the Zone Merge Analysis dialog box. Configuring Zone Merge Control Policies To configure merge control policies, refer to the Cisco MDS 9000 Family CLI Configuration Guide. Compacting the Zone Database for Downgrading Prior to Cisco SAN-OS Release 3.0(1), only 2000 zones are supported per VSAN. If you add more than 2000 zones to a VSAN, a configuration check is registered to indicate that downgrading to a previous release could 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 2000 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 2.x or earlier. Perform this procedure for every VSAN on the switch with more than 2000 zones. Note A merge failure occurs when a switch supports more than 2000 zones per VSAN but its neighbor does not. Also, zone set activation can fail if the switch has more than 2000 zones per VSAN and not all switches in the fabric support more than 2000 zones per VSAN. To compact the zone database for downgrading, refer to the Cisco MDS 9000 Family CLI Configuration Guide.
