    Clients are the switches that will be using the RADIUS server; each client must be defined. By default, all IP addresses are blocked. On dual-CP switches (SAN Director 2/128 and 4/256 Director), the switch sends its RADIUS request using the IP address of the active CP. When adding clients, add both the active and standby CP IP addresses so that users can still log in the event of a failover.

    In a stable fabric, frames are always delivered in order, even when the traffic between switches is shared among multiple paths. However, when topology changes occur in the fabric (for example, if a link goes down), traffic is rerouted around the failure, and some frames could be delivered out of order. Most destination devices tolerate out-of-order delivery, but some do not.

    Monitoring traffic To implement ISL Trunking effectively, you must monitor fabric traffic to identify congested paths or to identify frequently dropped links. While monitoring changes in traffic patterns, you can adjust the fabric design accordingly, such as by adding, removing, or reconfiguring ISLs and trunking groups in problem areas.

  • Page 337: Enabling And Disabling Isl Trunking

    Enabling and disabling ISL trunking You can enable or disable ISL Trunking for a single port or for an entire switch.When you execute the commands portCfgTrunkPort or switchCfgTrunk to update the trunking configuration, the ports for which the configuration applies are disabled and re-enabled with the new trunk configuration. As a result, traffic through those ports could be disrupted.

  • Page 338: Setting Port Speeds

    Setting port speeds For long-distance ports, if a port is set to autonegotiate port speed, the maximum speed (which is 4 Gbit/sec) is assumed for reserving buffers for the port–this wastes buffers if the port is actually running at 2 Gbit/sec.

For example, you can partition your SAN into two zones, winzone and unixzone, so that your Windows servers and storage do not interact with your UNIX servers and storage.

    Zone types Table 80 summarizes the types of Zoning. Table 80 Types of Zoning Zone type Description Storage-based Storage units typically implement LUN-based Zoning, also called masking . LUN-based Zoning limits access to the LUNs on the storage port to the specific WWN of the server HBA.

    Table 81 Approaches to fabric-based Zoning Zoning Description approach Operating Zoning by operating system has issues similar to Zoning by application. In a system large site, this type of zone can become very large and complex. When zone changes are made, they typically involve applications rather than a particular server type.

  • Page 346: Zone Objects, Zone Aliases, Zone Configurations, Zoning Enforcement

    Zone aliases also simplify repetitive entry of zone objects such as port numbers or a WWN. For example, you can use the name “Eng” as an alias for “10:00:00:80:33:3f:aa:1 1”. A useful convention is to name zones for the initiator they contain. For example, if you use the alias SRV_MAILSERVER_SLT5 to designate a mail server in PCI slot 5, then the alias for the associated zone is ZNE_MAILSERVER_SLT5.

  • Page 397: A Configuring The Pid Format, About Pids And Pid Binding, Summary Of Pid Formats

    Configuring the PID format PIDs Port identifiers (called ) are used by the routing and zoning services in Fibre Channel fabrics to identify ports in the network. All devices in a fabric must use the same PID format, so when you add new equipment to your SAN, you might need to change the PID format on legacy equipment.

  • Page 398: Impact Of Changing The Fabric Pid Format, Host Reboots, Static Pid Mapping Errors

    Impact of changing the fabric PID format If your fabric contains switches that use Native PID, it is recommended that you change the format to Core PID before you add the new, higher port count switches and Directors. Also, it is recommended that you use Core PID when upgrading the Fabric OS version on 2000 and 3000 series switches.

  • Page 399: Selecting A Pid Format

    CAUTION: After changing the fabric PID format, if the change invalidates the configuration data (see Table 91 to determine this), do not download old (pre-PID format change) configuration files to any switch on the fabric. Table 91 Effects of PID format changes on configurations PID format PID format after Configuration effect...

    Table 92 shows various combinations of existing fabrics, new switches added to those fabrics, and the recommended PID format for that combination. The criteria for the recommendations are first to eliminate host reboots, and second to minimize the need for a host reboot in the future.

    It is also important to understand how multipathing software reacts when one of the two fabrics is taken offline. If the time-outs are set correctly, the failover between fabrics should be transparent to the users. You should use the multipathing software to manually fail a path before starting maintenance on that fabric.

  • Page 403: Hybrid Update, Changing To Core Pid Format

    After the fabric has reconverged, use the cfgEnable command to update zoning. Update their bindings for any devices manually bound by PID. This might involve changing them to the new PIDs, or preferably changing to WWN binding. For any devices automatically bound by PID, two options exist: a.

    Determine if the current switch firmware versions meet the minimum supported version levels. Table 93 lists the earliest Fabric OS version levels that support Extended Edge PID format. Use this table to determine if you need to upgrade the firmware in the switches in your fabric before you change the PID format.

The proper usage would be vgimport –m <mapfile> <path_to_volume_group> <physical_volume_path>. For example: vgimport –m /tmp/jbod_map /dev/jbod /dev/dsk/c64t8d0 /dev/dsk/c64t9d0 Activate the volume groups using vgchange.

    If you are not using multipathing software, unmount the volumes from their mount points using umount. The command usage is umount <mount_point>. For example: umount /mnt/jbod If you are using multipathing software, use that software to remove one fabric’s devices from its configuration.
