Managing Secure Fabric OS Adding Switches and Merging Secure Fabrics If it becomes necessary to add a switch to a fabric, or to merge fabrics in order to simplify management or share fabric resources, then all switches and fabrics must be in the same state regarding Secure Mode and must have an identical FCS policy before they can be merged into one fabric. Any switches that do not match are segmented. For example, two fabrics that both have Secure Mode disabled can be merged, and two fabrics that both have Secure Mode enabled can be merged. However, if one fabric has Secure Mode disabled and the other fabric has Secure Mode enabled, they cannot be joined until both have Secure Mode either enabled or disabled. When a fabric is merged, the Security policy set, Zoning configuration, password information, and SNMP community strings are overwritten by the fabric whose version stamp is non-zero. Before merging, verify that the fabric that contains all the desired information has the non-zero stamp. Note: For general information about merging fabrics, including merging two or more fabrics that are not in Secure Mode, refer to the HP StorageWorks Fabric Operating System Procedures Version 3.1.x/4.1.x User Guide. Table 17 indicates the results of moving switches in and out of fabrics with Secure Mode enabled or disabled. Secure Fabric OS Version 1.0 User Guide 101

Secure Fabric OS Version 1.0 User Guide
Adding Switches and Merging Secure Fabrics
If it becomes necessary to add a switch to a fabric, or to merge fabrics in order to
simplify management or share fabric resources, then all switches and fabrics must
be in the same state regarding Secure Mode and must have an identical FCS policy
before they can be merged into one fabric. Any switches that do not match are
segmented.
For example, two fabrics that both have Secure Mode disabled can be merged, and
two fabrics that both have Secure Mode enabled can be merged. However, if one
fabric has Secure Mode disabled and the other fabric has Secure Mode enabled,
they cannot be joined until both have Secure Mode either enabled or disabled.
When a fabric is merged, the Security policy set, Zoning configuration, password
information, and SNMP community strings are overwritten by the fabric whose
version stamp is non-zero. Before merging, verify that the fabric that contains all
the desired information has the non-zero stamp.
Note:
For general information about merging fabrics, including merging two or more
fabrics that are not in Secure Mode, refer to the
HP StorageWorks Fabric Operating
System Procedures Version 3.1.x/4.1.x User Guide
.
Table 17
indicates the results of moving switches in and out of fabrics with Secure
Mode enabled or disabled.
