About this document These release notes describe the contents of the HAFM software kit, and any last-minute additions or notes on the configuration or use of HAFM software. Be sure to read these notes before installing the HAFM. This information is periodically updated and available on the following HP web site: http://www.hp.com/country/us/eng/prodserv/storage.html.
• Duplicate IP addresses erroneously allowed in Discover Setup Available Addresses list • Ethernet event may not be sent • Domain IDs may not display • SNMP traps are not displayed in the Event Log • Disconnected ISL may not generate Event Log entry • Cannot export to disk on remote AIX client • Cannot import a Physical Map • Errors drop down list is not available • Cannot configure a blank nickname • Support for speed Auto-Negotiate • Losing LAN connection to the HAFM appliance when logged in to HAFM • Eff
CD-ROM directory structure The HAFM software kit includes two CDs; the HP StorageWorks ha-fabric manager documentation and software CD (part number 516-000008-000, Rev A) and the HP StorageWorks ha-fabric manager clients CD (part number 516-000009-000, Rev A), which contains the files necessary to install HAFM. The HP StorageWorks ha-fabric manager documentation and software CD contains the following items at the root level directory: • Open_Bridge_Agent_Installer—Directory for installer • version.
• AIX • hpClientInstall.bin • HPUX • hpClientInstall.bin • Linux • hpClientInstall.bin • Solaris • hpClientInstall.bin • Windows • hpClientInstall.exe • version.txt • Documents • README.TXT—HP document structure; late-breaking doc changes • COPYRIGHT.TXT—Contains the copyright information HAFM software version 08.06.00 The HAFM appliance has the latest version of the HAFM software pre-installed.
Firmware files are included in the upgrade process, but release rules are not. Since release rules are required when sending another firmware version to a switch, an error results. To avoid this problem, add the latest firmware file to the firmware library. This also adds the new release rules and resolves the problem. HAFM 07.02.00 is not removed after upgrading to HAFM 08.xx.xx, and if the server is rebooted, both 07.xx.xx and 08.xx.xx services are started. Be sure to remove 07.02.

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. HAFM 08.06.00 allows managing of directors and edge switches running any of the versions of firmware listed in Table 2: Table 2 HAFM and firmware compatibility Firmware version 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.
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. Although products may coexist in a fabric running different levels of firmware, all products must be at the same major functional release level. HAFM upgrade required for firmware version 07.xx.xx To upgrade to firmware 07.00.00-84, you must first upgrade the HAFM software to 07.01.
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 06.00.00 or later before upgrading to 07.00.00-84. If a switch is operating with a firmware level earlier than 06.00.00, you must upgrade to 06.xx.xx before installing 07.00.00-84.
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 05.02.00-13 and later.
NOTE: You must have maintenance authorization rights to access the HAFM Product/Element Manager menu options used in this procedure. a. From Product/Element Manager Hardware view, verify that an amber LED indicator is not displayed for either CTP card. b. Right-click the CTP card you believe to be active. From the right-click popup menu, choose FRU Properties. Verify that it is the active CTP card. c. Right-click the active CTP card and choose Switchover from the popup menu.
For procedures to download firmware to the switch or director using the HAFM Element Manager interface or EWS interface, refer to the following: • The switch or director Installation and Service Manual. This publication provides complete procedures for obtaining firmware from the HP web site and downloading firmware to the switch or director using HAFM. • The switch or director Element Manager online help and User Manual.
second-generation Edge Switch 2/24 switches cannot be downgraded earlier than 05.03.01, they must be configured in Homogeneous Fabric Interoperability mode to remain concurrent. If this process is not followed, I/O through the switch may be significantly disrupted or stopped. Recovery for this situation is accomplished by reactivating the current zone set. If you are installing a new or replacement second-generation Edge Switch 2/12 or Edge Switch 2/24 into an existing 05.xx.
restricted to only those devices sharing at least one common zone with the device that changed. This way, only devices that are impacted by the change in connectivity receive RSCNs. The Zone FlexPar feature is available in both Open Fabric 1.0 and Homogeneous Fabric 1.0 Interop modes, as well as in environments with loop-attached devices. In Homogeneous Fabric 1.
• SSH for CLI—Secure Shell (SSH) provides an encrypted connection, as an alternative to Telnet, to secure CLI access to switches and directors. • Enhanced Maintenance Port Security—This allows users to enable enhanced authorization on the maintenance port, which is the switch or director RS-232 connection. Enhanced Authorization mode enforces stronger security policies, requiring users to change the well-known password to a case- sensitive private password the first time they use the maintenance port.
• Security Log—The Security Log is a new log available in EWS, CLI, and HAFM that records various events concerning integrity of a switch. This includes authorization or authentication problem detection, and approved and invalid access attempts. Each log entry provides an event number or reason, a date/time stamp, a trigger level (a type of security event severity), an event count, and a category and data pertaining to the specific event. The log wraps at 200 entries.
Embedded Port Log The Embedded Port Log is a new log that records all Fibre Channel traffic from or to the embedded port. This log is actually implemented as two logs, one that allows entry wrapping and one that stops adding entries when filled. The logs allow filtering based on Class F frames, as well as by port number, to isolate specific events or problems. This feature is intended for advanced users to diagnose and troubleshoot traffic problems within a SAN.
by default when using firmware 05.01.00-24 or greater and cannot be disabled. All HP-approved host bus adapters (HBAs) limit access to devices within their zones, so you will not see a change in fabric behavior unless you are using nonstandard HBAs. Hard zoning improves security against intruders that load nonstandard HBA drivers. 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.
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.
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.
Changing password in CLI When users are prompted to change the password when logging into the Command Line Interface (CLI), they can enter the default password (password). This will be accepted, however at the next login they will again be required to change the password if it is still the default password. When users enter the default password when prompted to change the password, new Security Log entry 10203, Default Password Not Changed, is posted.
managed via either LAN, the public LAN is the only one that can support remote client access. Thus, if one attempts to access the HAFM appliance via a remote client session and is unknowingly using what has been designated as the private LAN, the remote session is not allowed. The IP address that the HAFM appliance has determined to be the public LAN which supports remote client access, displays HAFM which displays after selecting SAN > Server Properties.
Workaround If the date/time of the HAFM appliance needs to be set to an earlier time, perform the following: 1. Exit the HAFM application. 2. Select Start > Programs > HP StorageWorks ha-fabric manager 8.6 > Stop Services. 3. Change the date/time on the HAFM appliance. 4. Select Start > Programs > HP StorageWorks ha-fabric manager 8.6 > Start Services. 5. Restart the HAFM application. This procedure works even if you previously set the date/time to an earlier time without using these steps.
Changing or removing the principal switch of a persisted fabric causes two fabrics to be displayed Fabrics are identified by the WWN of the principal switch. If a new principal switch is selected (either manually, or because the current principal switch is removed from the fabric), the fabric is reidentified by the WWN of the new principal switch.
Port Fencing dialog box may not reflect correct count of Affected Ports in ISL Thresholds table This usually occurs when a policy has been applied to an entire switch and there are already ports with a threshold policy applied, even when it is selected not to replace the existing policy on the switch ports.
Ethernet port failure on HAFM appliance may impact HAFM behavior On the HAFM appliance, the SNMP agent may appear to hang or respond slowly if the Ethernet port on the server fails and transmits bad frames. CPU usage and memory usage display abnormally high.
AIX client may not connect to HAFM appliance The remote client running on IBM AIX intermittently cannot connect to the HAFM appliance. AIX detects server when attempting login, but then displays a server not found and unable to connect message. Workaround If this issue is persistent, consider using an available HAFM client for another operating system.
Workaround A Physical Map can be imported as part of a full SAN import file. Errors drop down list is not available The Errors drop down list is not available in the Performance Graph for HAFM 08.06.00. Cannot configure a blank nickname Nicknames cannot be left blank. If no nickname has been configured yet, the user can select cancel to leave a nickname blank. Once a nickname has been configured, it cannot be changed to be blank, that is, the nickname cannot be deleted.
Losing LAN connection to the HAFM appliance when logged in to HAFM If the LAN connection to the HAFM appliance is lost while you are logged in to HAFM, the application may stop. Workaround The LAN connection must be restored. Stopping HAFM has no impact on the Fibre Channel operations of any edge switch or director. Monitoring switch operations, logging events, and implementing configuration changes are interrupted only while the LAN is not connected.
span of time. Discovery of a switch occurs when it is added to HAFM for management, and when the Ethernet connection to a switch is broken and reestablished, such as when a switch’s firmware is upgraded. Workaround When a switch has been added to HAFM for management, or firmware has been upgraded, observe the switch being shown as discovered by HAFM. Check the event log of the switch to ensure there were no faults that occurred during the short time when HAFM was in the process of discovering the switch.
HAFM appliance may shut down following a firmware download The HAFM appliance may shut down following a firmware download. If this occurs, you have to restart the HAFM appliance to recover. This is an issue with Java Virtual Machine 1.3.1_07, which is used in the application. This is only an issue when running firmware 06.00.01 or earlier.
