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.
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.
This occurs only in certain units with CTP cards. Units with CTP2 cards do not have this issue. If you get one of these messages during the upgrade, the firmware upgrade failed, but the unit continues working with the existing firmware without an interruption in service. 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.
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 pop-up menu, choose FRU Properties. Verify that it is the active CTP card. c. Right-click the active CTP card and choose Switchover from the pop-up menu. The director loses its Ethernet connection for a short period during the switchover process.
When downgrading to a release prior to 07.00.00-84, any modifications to the port RX BB_Credit settings using the new enhanced port configuration capability must be changed back to a configuration supported by older firmware. This is necessary to allow the configuration to comply with previous releases’ configuration database. Firmware 07.00.00-84 services verify compatibility and prevent downloads until the configuration conflict is resolved.
If a Director 2/140 in a multiswitch fabric is downgraded earlier than 06.02.00, ISLs could become segmented if there are any other switches in the fabric operating with a firmware version earlier than 06.01.00. To prevent this situation, downgrade all Director 2/140s in the fabric to 06.01.00 before downgrading any products in the fabric to 05.xx.xx. This problem only exists with Director 2/140s in the fabric. HAFM displays a warning message if a downgrade from 06.02.
Please contact your local HP technical resource to confirm compatibility with devices in your SAN before upgrading to this firmware version. For more information on upgrading software versions, refer to the HP StorageWorks HA-Fabric Manager User Guide. The features of this software version are detailed in the accompanying manuals listed in section Other director documentation.
Standard features The following SANtegrity features do not require a license or SANtegrity Binding. • CHAP Authentication for HAFM/SWAPI—This provides authentication of connections from the HAFM appliance service processor and SWAPI Direct Connect. This ensures that requested HAFM management sessions or SWAPI Direct Connect sessions are from a trusted source. • Encryption of Passwords and Secrets Shared with HAFM—All secrets and password information are passed in encrypted format for greater security.
• IP Access Control List—This allows users to establish a list of IP addresses from which the switch is allowed to accept connections. This prevents users who have access to the Ethernet LAN from attempting to access the Fibre Channel switches. Connection attempts from unauthorized IP addresses are ignored by the switch, making it appear that no device is connected.
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.
Workaround None. 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.
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. 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.
