Fabric OS 5.x administrator guide 195
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; it can also be downloaded
from the host to a switch in the fabric. See ”Backing up a configuration” on page 73, ”Restoring a
configuration” on page 74, or the configUpload and configDownload commands in the HP
StorageWorks Fabric OS 5.x command reference guide.
Table 40 presents zoning database size limitations for various Fabric OS release versions. The maximum
size of a zone database is the upper limit for the defined configuration, and it is determined by the amount
of flash memory available for storing the defined configuration.
Adding a new switch or fabric
When a new switch is added to the fabric, it 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 it
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, 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:
• Check the following before merging zones, 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.
• Secure Fabric OS: If one switch has Secure Fabric OS enabled, all switches in the fabric must have
Secure Fabric OS. See the HP StorageWorks Secure Fabric OS administrator guide for more
information.
• Merging and segmentation: The fabric is checked for segmentation during power-up, when a switch is
disabled or enabled, or when a new switch is added.
The database is the zone configuration database. This is the data displayed as the defined
configuration in the cfgShow command. It is stored in nonvolatile memory by the cfgSave
command. This database is a replicated database, which means that all switches in the fabric have a
