About this document — RP505ENU.EXE—Windows installation file for Acrobat Reader 5.0 with Search Supported configurations Operation of multiple switches in a fabric topology is subject to the following topology limits. Consider the impact of these limits when planning the fabric. Note: For more information about planning the fabric, refer to HP StorageWorks SAN High Availability Planning Guide.
About this document Cable requirements Note: Optical cables for the Edge Switch 2/12, Edge Switch 2/12, and Edge Switch 2/32 must be ordered separately. For cables measuring up to 500 meters (1 Gbps) or 300 meters (2 Gbps), use multi-mode Fibre Channel cables. For longer cables, use single-mode Fibre Channel cables. Multi-mode optical cables are connected to short-wave optical transceiver modules in a switch. Single-mode optical cables are connected to long-wave optical transceiver modules in a switch.

About this document Before upgrading firmware, it is highly recommended that you back up the director or edge switch configuration. Refer to your HP StorageWorks Edge Switch Element Manager User Guide for more information. Embedded Web Server (EWS) also provides an option to print or save product configuration to a file. Refer to the HP StorageWorks Embedded Web Server User Guide for more information. All products must be running firmware 05.00.00 or later before upgrading to 06.02.00-22.
About this document Edge switch products already running 05.01.00 or later continually validate the NVRAM configuration, so risk of an outage is extremely low. For edge switch products running an earlier version of firmware, the risk of an outage increases due to the NVRAM issue. If an outage compromises system integrity, HP recommends that the edge switch firmware upgrade be a scheduled maintenance action that anticipates the failure of switch connectivity. This issue was corrected with firmware 05.02.
About this document Note: The Director 2/140 and the Edge Switch 2/24 cannot be downgraded earlier than 04.01.00, and the Edge Switch 2/12 cannot be downgraded earlier than 05.05.00. Downgrades directly to 05.03.01 from 06.xx.xx is not concurrent when the second-generation Edge Switch 2/24 is configured in Open Fabric operating mode. In other words, downgrades in Open Fabric mode cannot be done with the second-generation Edge Switch 2/24 online without disrupting port operations.
About this document HAFM upgrade required for firmware version 06.xx.xx To upgrade to firmware 06.xx.xx, you must first upgrade the HAFM software to 07.01.00-9 minimum, if you are using the notebook HAFM server to manage the director or edge switch. The HAFM software is contained on the HP StorageWorks ha-fabric manager documentation and software CD (Part Number 516-000024-820). An upgrade kit to HAFM 07.01.00-9 is also available, Part Number 320908-B22, for owners of license for previous versions.
About this document OSMS change Open Systems Management Server (OSMS) is now available as a standard feature. OSMS can be enabled/disabled via EWS, Command Line Interface (CLI), and HAFM. Default zone is disabled by default The default zone on the Edge Switch 2/12, Edge Switch 2/24, and Edge Switch 2/32 is disabled by default. Zoning must be configured in order for any devices connected to the edge switches to communicate.
About this document Zoning change RSCN control Normally, when a zone set is activated, a fabric format domain Register State Change Notification (RSCN) is sent to all devices in the fabric. With firmware 05.00.00 or later, you can disable these RSCNs from being sent. This is done using the Suppress RSCNs on zone set activations check box on the Configure Switch Parameters dialog box. This feature significantly changes the normal behavior of the fabric.

About this document For customers who want to add a second-generation switch to their existing SAN, but are not ready to upgrade their SAN from 5.x to 06.02.00, there is a downgrade firmware version for each of these edge switches which provides compatibility with a SAN running 05.02.00. Firmware 05.03.01-01 is available for the Edge Switch 2/24, and firmware 05.05.01-01 is available for the Edge Switch 2/12.
About this document The feature configures a switch or director so that no frame data is stored after a power off. Without Full Volatility, if the switch or director experiences a fault condition, a dump of the embedded memory space is captured into non-volatile memory. This dump retains the last 30 frames transmitted from and last four frames transmitted to the embedded port. With Full Volatility installed, this dump does not occur when a fault condition occurs.
About this document When a Preferred Path is defined for all of the ports on a switch, it provides a reasonable level of predictability because it isolates changes in routing only to the ports affected by a particular “preferred path.” Thus, if the “preferred path” goes away, only the ports assigned to the path are rerouted to other paths. Conversely, if the “preferred path” is re-established, the ports assigned to the path are rerouted back to the path.
About this document Full-fabric capability for Edge Switch 2/12 Unlike other edge switch and director products, a product feature enablement (PFE) key, controls Edge Switch 2/12 E_Port-to-E_Port connections. Once the feature key is purchased and installed, the switch can be configured for E_Port connections on any of the active ports. The feature key includes distance support. With firmware 06.00.
About this document Known issues This section describes the known issues related to the Edge Switch 2/12, Edge Switch 2/24, and Edge Switch 2/32. Certain unauthorized devices may increase response time for fabric operations under specific conditions with the Edge Switch 2/24 When Port Binding is enabled, unauthorized devices (devices that are not set up by the Port Binding) with older technology can transmit numerous fabric login (FLOGI) requests, which are rejected by the Edge Switch 2/24.
About this document ISL disconnect causes NOS error with the OpenVMS operating systems When an ISL connection is physically removed between directors or switches, the Fibre Channel Adapter model FCA2354 transmits a Not Operational Sequence (NOS) error. This is observed as an entry in the HAFM appliance Link Incident log for the port in which the FCA2354 is attached. The director’s Hardware View also displays a yellow triangle icon over the port that detected this incident.
About this document Ports may accumulate spurious events A port may accumulate Invalid transmission word and Bit-Error Threshold Link Incident events when a transceiver is poorly seated, resulting in a poor ground connection. Workaround Reseating the optical transceiver corrects the problem.
