See ” Administering advanced zoning ” on page 177 for additional information about setting up zoning
properly. Also see the HP StorageWorks Fabric OS 5.x command reference guide for details about
zoning commands.
Correcting a fabric merge problem quickly
You can correct zone conflicts by using the
cfgClear
command to clear the zoning database.
To correct a merge conflict without disrupting the fabric, first verify fabric merge problem, and then edit
zone configuration members, and then reorder the zone member list.
CAUTION: This is a disruptive procedure.
1. Determine which switches have the incorrect zoning configuration, and then log in to the switches
as admin.
2. Issue the
switchDisable
command.
3. Issue the
cfgDisable
command.
4. Issue the
cfgClear
command.
CAUTION: This command clears the zoning database on the affected switches.
5. Issue the
switchEnable
command.
This forces a zone merge and populates the switches with the desired zoning database. The two
fabrics merge again.
Verifying a fabric merge problem
1. Issue the
switchShow
command to validate that the segmentation is due to a zone issue.
2. See Table 24 on page 149 to view the different types of zone discrepancies.
