Zone Merge-Control Restrict - HP 5920 Series Command Reference Manual

To improve the security for a VSAN, you can enable hard zoning for the VSAN. When soft zoning can
meet the access control requirements of a VSAN, you can disable hard zoning for the VSAN to save the
hardware entry resources.
After hard zoning is enabled for a VSAN, the system begins to deploy all zone rules of the VSAN. After
hard zoning is disabled for a VSAN, the system clears the hardware zone rules already deployed for the
VSAN and stops deploying new zone rules.
In enhanced zoning mode, the switch distributes hard zoning status with other zone data. In basic zoning
mode, you must manually configure hard zoning to ensure consistency across the fabric.
You can use the display zone status command to view the hard zoning status.
Do not configure this command when the switch is merging or distributing zones.
Examples
# Disable hard zoning for VSAN 2.
<Sysname> system-view
System View: return to User View with Ctrl+Z.
[Sysname] vsan 2
[Sysname-vsan2] undo zone hard-zoning enable

Usage guidelines
Two merge control modes are available: Restrict and Allow. For more information about the Restrict and
Allow merge control modes, see FC and FCoE Configuration Guide.
In enhanced zoning mode, the merge control mode affects the result of a merge operation. Also, a merge
operation is allowed only when the merge control mode is the same on both participating switches.
Otherwise, the merge operation fails, and the link connecting the participating switches is isolated.
This command is supported only in enhanced zoning mode. To ensure a consistent merge control mode
across the fabric, use the zone activate or zone distribute command after you configure this command.
