About this document These release notes contain late breaking and supplemental information for the Director 2/64 and Director 2/140. Be sure to read these release notes before installing a Director 2/64 and Director 2/140. This information is periodically updated and available on the following HP web site: http://www.hp.com/country/us/eng/prodserv/storage.html.
For more information on upgrading firmware versions, refer to the appropriate HP StorageWorks director service manual. The features of this firmware version are detailed in the following manuals.
• HP StorageWorks Director release notes, AA-RTDVG-TE/958–000276–007 CD-ROM directory structure The HP StorageWorks director documentation and firmware CD contains the following items: • Manuals.pdf—HP StorageWorks Director 2/64 and Director 2/140 Documentation; links to the following documents and search function • Documents • README.
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 Director 2/64 and Director 2/140 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.
Zonesets containing domain/port number zones while in Open Fabric interop mode no longer cause zoning to hang When directors and edge switches in a fabric were configured for Open Fabric 1.0 interop mode, and the fabric’s zoneset contained a zone with members defined by domain/port number instead of World Wide Name, activating changes to the zoneset could cause the Zone Manager to hang.
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 8 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 07.01.02 If you are using HAFM, firmware 07.01.02 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.
The upgrade process checks for sufficient memory before activating the new firmware image. The firmware upgrade does not complete without sufficient memory. Please contact HP Customer Support if you receive this message. Some customer environments use application or host software that is affected by the restart of the director CTP during a HotCAT download operation. Applications that rely on inband management servers are especially prone to problems caused by processor restart.
When switchover occurs, the green LED illuminates on the backup CTP card to indicate that it is now the active card. NOTE: You must have maintenance authorization rights to access the HAFM Product/ Element Manager menu options used in this procedure. 5. Upgrade the firmware to 05.02.00-13 on each director using the Send option on the Firmware Library dialog box.
• EWS User Manual. This provides procedures for downloading firmware to the switch or director. • EWS online help. This provides procedures for downloading firmware to the switch or director. Downgrading directly to a release before 06.00.00 from 07.01.02-4 is not allowed. To downgrade to a release before 06.00.00, you must first downgrade to 06.YY.ZZ. Upgrades and downgrades are supported only from one major release to the next, such as from 06.xx.xx to 07.01.02-4.
HAFM upgrade required for firmware version 07.xx.xx To upgrade to firmware 07.01.02-4, 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.
With the Zone FlexPar feature enabled, RSCN messages for a zoning change are handled like RSCNs for availability/unavailability changes. Specifically, RSCNs are 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.
• RBAC Phase I: Enhanced User Rights Configuration—RBAC is role based access control. This is the first phase of more comprehensive role-based access control planned for the CLI and EWS interfaces. Multiple users can now be configured for EWS or CLI, or both, through either interface. This allows users to configure additional user name/password combinations. • SSH for CLI—Secure Shell (SSH) provides an encrypted connection, as an alternative to Telnet, to secure CLI access to switches and directors.
To configure this feature, users set policies with thresholds based on the number of port events occurring during a set time period. If a port generates enough events to exceed the policy threshold, the port is automatically blocked and the user is notified. Transmit and receive traffic is disabled until the user can investigate, solve the problem, and manually unblock the port. Embedded Audit Log The Audit log is a new log available through CLI and EWS.
Some IP addresses must be avoided If you use HAFM to manage other M-Series Fabric directors and edge switches, when you select IP addresses for edge switches, directors, and for the HAFM appliance, do not use IP addresses in the following range: 192.168.0.0 through 192.168.0.255—This subnet is used internally to the HAFM appliance. Using an IP address in this range causes the call-home feature to function incorrectly. Hard zoning Hard zoning is a security enhancement introduced in firmware 05.01.
• • • • FCEOS MIB: 2.0 SNMP Framework MIB: RFC-2271 (1997/09/30) FA MIB: 3.0 FA MIB: 3.1 SNMP requests can be received in either 3.0 or 3.1 of the Fibre Alliance (FA) MIB, and the switch responds in the same version. The switch can also be configured to use a specific version for traps generated by the switch. 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.
Firmware 06.02.00-22 provides support for second-generation Edge Switch 2/12 and Edge Switch 2/24 switches. This is the minimum M-Series firmware supported on the second-generation Edge Switch 2/12 and Edge Switch 2/24. 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.
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.
BB_Credit Allocation for ports With firmware 07.00.00 and later, this supports the ability to allocate a specific number of buffer credits per port. This feature provides benefit primarily in the Edge Switch 2/12 and 2/24 switches, where a single pool of buffers is shared among all ports. Users will now be able to allocate buffer credits only where needed.
NOTE: This limit is disabled when the switch parameter Suppress Zoning RSCNs on Zone set activations check box is enabled. Known issues This section describes the known issues related to the Director 2/64 and Director 2/140. HSG80 transparent mode not supported with IBM AIX Use of an HSG80 with IBM AIX is restricted to operating the HSG80 in Multibus mode with the Director 2/64 and Director 2/140. Transparent mode is not supported at this time. Workaround None.
Workaround Use these steps to clear the incident alerts. 1. At the HAFM Hardware View, click the port module to open the Port Card View. 2. Right-click on the port with the yellow triangle icon, and choose Clear Link Incident Alert(s). Support for speed Auto-Negotiate Auto-negotiate is supported.
Workaround If this condition occurs, the configuration of the edge switch or director must be restored, and the IP address must be restored. Also, all licensed features need to be reactivated by entering the license keys again. SNMP issues SNMP traps warmStart and coldStart are not always received across Ethernet switches. Workaround None.
