Consider the impact of these limits when planning the fabric.
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.
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.

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.
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. Upgrading firmware on an edge switch from 04.xx.xx to 05.xx.xx An issue has been identified in release 04.xx.
Before downgrading below 07.01.02-4, there can only be one user assigned access rights as Administrator and one user assigned as Operator for Embedded Web Server and CLI. If additional users were created, you have to delete them before downgrading. Firmware 07.01.02-4 does not allow the last user with Administrator rights in Embedded Web Server or CLI to be deleted. If no Operator user exists, firmware 07.01.02-4 automatically creates one for each interface during the downgrade.
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. Since 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 you are using the 1U rack-mount HAFM appliance to manage the director or edge switch, the minimum HAFM version required is 07.02.00-9, which is the minimum version installed. This HAFM software is contained on the HP StorageWorks ha-fabric manager documentation and software CD (Part Number 516-000024-720). The previous minimum versions of HAFM allow you to manage directors or edge switches running 07.01.
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 1.0 mode, the default zone is treated like any other zone, and RSCNs are sent only to the affected devices if the default zone is enabled or disabled. A PFE key is not required for the Zone FlexPar feature, and it can be enabled or disabled through CLI for a specific switch. When upgrading to firmware 07.01.
• 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. Subsequent access by service personnel will require log in through the private customer-level access.
Embedded Audit Log The Audit log is a new log available through CLI and EWS. This is not the same Audit Log available through HAFM. The log records all configuration changes to the switch to provide data for analyzing problems caused by configuration changes. 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.
2.168.0.0 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 05.01.00-24 that prevents ports from accessing devices outside their zones. Hard zoning is enabled by default when using firmware 05.01.00-24 or greater and cannot be disabled.
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. 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.
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. 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.
Workaround None. HSG80 transparent mode not recommended with controller in SCSI-3 mode with HP-UX operating systems Due to an issue with nonexistent duplicate LUNs being displayed with the HP-UX operating systems, the HSG80 controller is restricted to SCSI-2 mode of operation when set to Transparent failover mode. SCSI-3 mode of operation in Multibus failover mode is fully supported with the use of Secure Path software, 3.0 or later versions. Workaround None.
Workaround If an older HBA has difficulty logging into a switch port that has its port speed configured as Negotiate, configure that port speed to 1Gb/sec or 2Gb/sec according to the operation speed of the HBA connected to that port. 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.
