Managing zoning configurations in a fabric
To modify an existing zone configuration, you can add, delete, or remove individual elements to create
the desired configuration. After the changes have been made, save the configuration to ensure the
configuration is permanently saved in the switch and that the configuration is replicated throughout
the fabric.
The switch configuration file can also be uploaded to the host for archiving and it can be downloaded
from the host to a switch in the fabric. See ” Backing up a configuration ” on page 75 and ” Restoring a
configuration ” on page 76, or the
configupload
and
configdownload
commands in the HP
StorageWorks Fabric OS 4.x command reference guide.
Table 21 presents zoning database size limitations for various Fabric OS release versions.
Adding a new switch or fabric
When a new switch is added to the fabric, it automatically takes on the zone configuration information
from the fabric. Use the
cfgactvshow
command to verify that the zoning information is the same on
each switch in the fabric.
If you are adding a switch that is already configured for zoning, use the
cfgclear
and
cfgsave
commands (or use
cfgclear
and
cfgdisable
if there is an effective configuration) before connecting
the switch to the zoned fabric.
Adding a new fabric that has no zone configuration information to an existing fabric is very similar to
adding a new switch. All switches in the new fabric inherit the zoning configuration data. If a zone
configuration is in effect, then the same configuration becomes the enabled configuration. The
cfgactvshow
command displays the same information on all switches in the newly formed fabric.
Before the new fabric can merge successfully, it must pass the following criteria:
• Before merging zones—To facilitate merging, check the following before merging switches or fabrics.
• Zoning licenses: All switches must have a zoning license enabled.
• Native operating mode: All switches must be in the native operating mode.
• HP Secure Fabric OS: If one switch has HP Secure Fabric OS enabled, all switches in the fabric
must have HP Secure Fabric OS. Refer to the HP StorageWorks Secure Fabric OS user guide for
more information.
