[. . . ] If the fabrics have different zone configuration data, the two sets of zone configuration data are merged, if possible. If not possible, the interswitch link (ISL) is segmented. A merge is not possible if any of the following conditions exist: HP StorageWorks Zoning Version 2. 6. 1 User Guide 23 Using Zoning Configuration mismatch Zoning is enabled in both fabrics and the zone configurations that are enabled are different in each fabric. The name of a zone object in one fabric is used for a different type of zone object in the other fabric The definition of a zone object in one fabric is different from the definition of zone object with the same name in the other fabric. Type mismatch Content mismatch Transactional Model Zoning commands are executed under the transactional model. A working copy of defined configurations is created by copying all information from zone or cfg lists at the start of a transaction. Issue the following commands to open a transaction: aliAdd aliCreate aliDelete aliRemove cfgAdd cfgCreate cfgDelete cfgRemove qloopAdd qloopCreate qloopDelete qloopRemove zoneAdd zoneCreate zoneDelete 24 HP StorageWorks Zoning Version 2. 6. 1 User Guide Using Zoning zoneRemove cfgSave cfgEnable cfgDisable Issue the following commands to end a transaction: When a transaction is opened, all new zoning information is placed in a transactional buffer. Unless the transaction is closed, the new changes are not applied to the fabric. A transaction is aborted by the cfgTransAbort command, or when another switch closes its transaction. When a transaction is closed, all new (from the transactional buffer) and existing zoning information is saved to memory and applied to the fabric. HP StorageWorks Zoning Version 2. 6. 1 User Guide 25 Using Zoning 26 HP StorageWorks Zoning Version 2. 6. 1 User Guide Using QuickLoop Zones 4 In addition to zoning fabrics, covered in Chapter 3, zoning also allows you to zone QuickLoops. By partitioning selected devices within a QuickLoop into a QuickLoop zone, you can enhance management of a Fibre Channel Arbitrated Loop (FC-AL) in a legacy environment. In QuickLoop zoning, devices within a QuickLoop can be partitioned off within that QuickLoop to form QuickLoop zones. In other words, a QuickLoop zone is a subset of a QuickLoop and can include only QuickLoop devices. Fabric zones and QuickLoop zones are independent of each other; both types of zone can coexist in the same zone configuration; QuickLoop devices can be included within a fabric zone configuration. QuickLoop Zoning Advantages In addition to all the advantages of fabric zoning--security, customization of environments, and optimization of IT resources--QuickLoop zoning can protect devices from disruption by unrelated devices during a critical process; for example, during a tape backup session. In a QuickLoop with zoning enabled, transmission of the loop initialization primitive (LIP) signal and loop initialization are controlled by the switch; the LIP is transmitted only to looplets within the affected zone; other looplets on the QuickLoop are not affected. In this way, unwanted disruption to devices can be controlled. QuickLoop Zones QuickLoop zones are hardware enforced; switch hardware prevents unauthorized data transfer between ports within the zone allowing devices to be partitioned into zones to restrict system access to selected devices. Once devices are included in a zone, they are visible only to other devices within that zone. HP StorageWorks Zoning Version 2. 6. 1 User Guide 27 Using QuickLoop Zones QuickLoop zone members are designated by looplet (port number) or by Arbitrated Loop Physical Address (AL_PA). There are 126 unique AL_PAs per QuickLoop; a QuickLoop zone can contain no more than 126 addresses. Configuring QuickLoop Zones To configure QuickLoop zoning, follow these steps: 1. A QuickLoop is comprised of FL_ports on one or two switches within the fabric. To create a QuickLoop, specify a QuickLoop name (called a qloop for zoning), followed by a list of AL_PAs to be included. QuickLoop names define the switch (or pair of switches) that make up the QuickLoop. A QuickLoop name must be a unique alphanumeric string beginning with an alphabetical character. The underscore (_) is allowed; names are case sensitive. [. . . ] The zone member list must have at least one member; empty lists are not allowed. The members are described by a list of member definitions separated by semicolons. Specify a physical fabric port number as a pair of decimal numbers s, p where s is the switch number (domain ID) and p is the port number on that switch. For example, "2, 12" specifies port 12 on switch number 2. [. . . ]
