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. • Fabric Elements—Each fabric element is defined by a unique domain ID that ranges between 1 and 31; therefore, the theoretical limit of interconnected directors in a single fabric is 31.
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.
Documentation released with firmware 07.00.00 and HAFM 08.06.00 To support these products, we are providing documentation from both McDATA Corporation (the product developer) and from HP (the product OEM). The HP documents include all information HP has incorporated into the products to date. The McDATA documents include only the basic product information. Table 1 shows HP terminology and McDATA Corporation equivalents used in the McDATA documents.
HAFM and firmware compatibility Table 2 lists the minimum version of HAFM that can run with the various versions of firmware for the directors and edge switches. Table 2 HAFM and firmware compatibility Firmware version 10 HAFM version (minimum) 01.01.02 04.00.01 (HP EFCM) 01.02.02-06 04.01.02-14 (SDCM) 01.03.00-35 04.02.00-40 (HP EFCM) 01.04.00-01 04.02.00-40 (SDCM) 02.00.00-33 06.00.00-45 (HP EFCM) 02.00.02-01 06.00.02-06 04.01.02-04 06.03.01-05 05.02.00-13 07.01.
Prerequisites for installing and using firmware 07.00.00 If you are using HAFM, firmware 07.00.00 requires HAFM 07.01.00 or later (check with HP Customer Support for the latest shipping version of HAFM). HAFM should be at the minimum level before installing the new firmware. NOTE: HAFM is not required for operating hardware products using the firmware. All directors and edge switches in the same fabric should have the same firmware level installed.
A small number of early-shipped Surestore Director FC-64 units may receive one of the following messages when they upgrade to firmware 05.02.00-13: • HAFM—Firmware cannot be loaded due to insufficient CTP memory. • EWS—File System Error: firmware version. Insufficient memory for new This occurs only in certain units with CTP cards. Units with CTP2 cards do not have this issue.
Considerations for downgrading the version of firmware Directors or edge switches are not required to be offline before performing a firmware downgrade operation. Limitations to downgrades are clearly identified if there are any limitations to performing the operation. Before downgrading 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.
Upgrades and downgrades are supported only from one major release to the next, such as from 06.xx.xx to 07.00.00-84. If EWS is used for upgrades and downgrades, and this rule is not followed, errors occur and there may be a disruption to attached devices. Downgrading to release 6.0 with the Preferred Path feature configured could cause loss of this function. HP recommends that Preferred Path be disabled before downgrading.
NOTE: The warning message is displayed when downgrading any model from 06.02.00, but only applies to downgrade operations for the Director 2/140. Firmware downgrades should not be performed using EWS and Internet Explorer v5.00.3315.1000x. If this operation is performed, the download operation may not complete and may eventually time-out leaving the switch with the previous version of firmware. HAFM upgrade required for firmware version 07.xx.xx To upgrade to firmware 07.00.
Zone FlexPar feature Because zoning is managed on a fabric-wide basis, all switches and directors in the fabric must maintain the same zoning configuration. This configuration is maintained automatically through the Fibre Channel protocol. To keep this information current, RSCN messages are sent through the fabric to inform attached devices when zoning changes occur, when devices become available, or when devices become unavailable.
• Encryption of Passwords and Secrets Shared with HAFM—All secrets and password information are passed in encrypted format for greater security. This prevents “snooping” of Ethernet connection to capture user login and authentication secret information. • RADIUS Server Support—This provides support for IETF RADIUS (Remote Authentication Dial In User Service) protocol for password authentication. Firmware 07.00.00 allows users to configure settings for using a RADIUS server.
Advanced Fabric Diagnostics This provides tools to monitor the fabric and identify potential problems before they impact network and application performance. Tools include ISL Fencing, new switch-centric Fabric and Embedded Port Logs, an Audit Log for the embedded user interfaces, and access to the Digital Diagnostic capabilities included with newer SFP transceivers.
Embedded Fabric Log The switch-based fabric log records events related to the following services: • Fabric Controller • Path Selection • Login Server • Name Server The Fabric log is actually implemented as two logs, one that allows entry wrapping and one that stops adding entries when filled. This log is intended to provide information for analyzing fabric and switch behaviors and problems. The Fabric log is available via EWS, CLI, and HAFM.
Hard zoning is compatible with legacy zone definitions, including World Wide Name (WWN) and port zoning. You can use your existing zones and zone sets without any changes. There are no changes to the zoning interfaces, so you do not need to modify your zone management practice, modify your documentation, or retrain Storage Area Network (SAN) administrators. Hard zoning controls access at the ingress port. When a port attempts to send a frame to a destination outside its zones, the frame is blocked.
Zoning limitations With firmware 06.00.00 and later, you have the ability to configure large zone sets, including up to 1024 zones and 1024 end ports in a single zone set. Table 3 shows the supported limits for the edge switches and directors.
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. These versions are installed only on the Edge Switch 2/24 and Edge Switch 2/12, and only when these switches are placed in a M-Series SAN running 05.02.00 firmware. A copy of these versions of firmware, are contained on the HP StorageWorks edge switch documentation and firmware CD (Part Number 524-000001-005).
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 nonvolatile 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.
Configuration Backup With firmware 07.00.00 and later, this allows users to save switch configuration settings to a standard XML format file, compatible with both HAFM and the Configuration Backup and Restore (CBR) utility. Customers can easily save configuration settings when switch configuration is accidentally modified or at hardware failure. A restore function is not yet available in EWS, but is planned for a future release.
Zoning enhancement to reduce fabric congestion In Homogeneous Fabric mode, an enhancement was added to reduce unnecessary fabric congestion when performing fabric-wide zoning operations that impact the Default Zone. This enhancement limits the number of members allowed in the Default Zone to 64.
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.
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.
Workaround Reseating the optical transceiver corrects the problem. Possible switch reset after power failure or power off sequence In extremely rare instances, after a power failure or power off sequence, an edge switch or director configuration may be reset to factory default settings. This is evident when HAFM is unable to communicate with the edge switch or director after being powered on.
