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

• 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. The supported limit of interconnected switches inasinglefabricis24. Becausethisnumberissubjecttochange,contactyour HP authorized service representative for the current number of interconnected switches supported in a single fabric.

• Inhomogeneous fabric—To determine if interoperability is supported for a

product, or if restrictions apply, refer to the product publications, or contact your HP authorized service representative.

• Number of Interswitch Links (ISLs)—The maximum supported number of ISLs

for edge switches is a ll available switch ports. For redundancy, at least two ISLs should connect any two switch-class fabric elements. Because this number is subject to change, contact your HP authorized service representative for the current number of ISLs supported per switch.

• Hop Count—The Fibre Channel theoretical limit of ISL connections traversed (hop

count) in a single path through a fabric is seven. The maximum supported hop count in a single path through a fabric is three. Because this number is subject to change, contact your HP authorized service representative for the current hop count supported by a single fabric path.

The hop count is equal to the number of ISL connections traversed in a single path, not the total number of ISL connections between devices.

Cable requirements

NOTE:

Optical cables for 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 shor t-wave optical transceiver modules in a switch. Single-mode optical cables are connected to long-wave optical transceiver modules in a switch. Multi-mode cables should use 50/125 optical ﬁbers, and single-mode cables typically use 9/125 optical ﬁbers for distances up to 10 km.

Verify that connectors interfacing with the Edge Switch 2/12, Edge Switch 2/24, and Edge Switch 2/32 use LC Duplex connectors with a PC ﬁnish. In addition, the connector at the opp osite end of the cable must be of either LC or SC type, depending on the requirements of the connected device.

Minor Code Enhancements and Fixes in fw 07.01.02-4

This release of ﬁrmware version 07.01.02-4 incorporates some minor code enhancements and ﬁxes, and is not a mandatory upgrade, though HP recommends that all directors and edge switches be upgraded to this version of ﬁ rmware. Firmware release 07.01.02-4 is based on ﬁrmware 07.00.00-84, and contains all ﬁxes included in that version and prior releases. The following are now incorporated in ﬁrmware version 07.01.02-4.

Directors take new action upon detecting a failed UPM port module

A particular type of failure in director UPM port modules could be disruptive to other port modules in a director. In the release of ﬁrmware 07.01.02-4, the action taken by the director upon detecting this type of failure was changed to power off the failed port module to prevent it from affecting other working port modules.

Embedded Web Server zoneset activation timeout issue resolved

Under cer tain conditions, the Embedded Web Server (EWS) would sometimes not allow theZoneManagersubsystemenoughtimetoprocessaconﬁguration change request. This would cause EWS to time out when waiting for the Zone Manager to respond. When this occurred, the Zone Manager could hang indeﬁnitely, preventing any further zone activities from any management location. This timeout issue has been ﬁxed.

Edge Switch release notes

Zonesets containing domain/port number zones while in Open Fabric interop mode no longer cause zoning to han

When directors an interop mo d e, and domain/port number instead of World Wide Name, activating changes to the zoneset could cause the Zone Manager to hang. When this occurred, the Zone Manager cou ld hang indeﬁnitely, preventing any further zone activities from any management location. It should be noted that domain/port number zones are not suppor ted in Open Fabric

1.0 interop mo conditions, and these zones are still ignored in Open Fabric 1.0 interop mode.

Occasional Ethernet hang issue is resolved

Under certain conditions, the Ethernet communications could intermittently hang on director 2/140, edge switch 2/24, and edge switch 2/12. This issue has been corrected.

If you are using HAF HP Customer Suppo minimum level bef

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 co-exist in a fabric running different levels of ﬁrmware, all products must be at the same major functional release level.

M, ﬁrmware 07.01.02 requires HAFM 07.01.00 or later (check with

rt for the latest shipping version of HAFM). HAFM should be at the

ore installing the new ﬁrmware.

Upgrading from an earlier version of ﬁrmware

Upgrading to ﬁrmware 07.01.02-4 is non-disruptive to attached devices. The director or edge switch is not required to be ofﬂine before performing an upgrade operation. Limitations to upgrades are clearly identiﬁed if there are any limitations to performing the operation.

Before upgrading 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. 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

07.01.02-4. If a switch is operating with a ﬁrmware level earlier than 06.00.00, you mustupgradeto06.xx.xxbeforeinstalling07.01.02-4.

Upgrades and downgrades are supported only from one major release to the next, such as from 06.xx.xx to 07.01.02-4. 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.

If upgrading to ﬁrmware 06.02.00-22 requires you to upgrade from 04.xx.xx to

05.xx.xx in the process, there are special considerations, as detailed in the section,

Upgrading ﬁrmware on an edge switch from 04.xx.xx to 05.xx.xx.

A s ma ll 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: Insufficient memory for new

firmware version.

This occurs only in certain units with CTP cards. Units with CTP2 ca rds do not have this issue.

Edge Switch release notes

Page 12

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 mem ory 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.

To safely upgrade ﬁ rmware on a edge switch, perform the following:

1. Upgrade HAFM software on the HAFM server/appliance to 07.01.00 (minimum).

Considerations for downgrading the version of ﬁrmware

Directors or edge switches are not required to be ofﬂinebeforeperformingaﬁrmware 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 ManagerUserGuidefor more information. EWS also provides an option to print or save product conﬁguration to a ﬁle. Refer to your HP StorageWorks Embedded Web Server User Guide for more information.

Page 13

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. If more than one Administrator and/or one Operator exists for Embedded Web Server and/or CLI, when attempting to downgrade you are prompted to delete one of them ﬁrst.

When downgrading to a release prior to 07.01.02-4, 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. Thisisnecessarytoallow the conﬁguration to comply with previous releases’ conﬁguration database. Firmware

07.01.02-4 services verify compatibility and prevent downloads until the conﬁguration

conﬂict is resolved.

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. These

includes instructions for downloading ﬁrmware to the switch or director using the HAFM interface.

• EWS User M anual. 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 downgradetoareleasebefore06.00.00,youmustﬁrst downgrade to 06.YY.ZZ.

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. To do this, deselect the check box for Enable Preferred Path in the Conﬁgure Preferred Paths dialog box.

NOTE:

The Director 2/ 1 40 and the Edge Switch 2/24 cannot be downgraded earlier than

04.01.00, and the Edge Switch 2/12 cannot be downgraded earlier than 05.05.00.

Edge Switch release notes

Page 14

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 modecannotbedonewiththe second-generation Edge Switch 2/24 online without disrupting port operations. Since second-generation Edge Switch 2/24 switches cannot be d owngraded 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.xx fabric, HP recommends that you downgrade theunitbeforeinstallingitintothefabric.

Downgrading to 05.05.00 is supported only on ﬁrst-generation Edge Switch 2/12 switches. Second-generation Edge Switch 2/12 switches can be downgraded only to

05.05.01. Second-generation Edge Switch 2/24 switches can be downgraded only to 05.03.01.

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 op erating 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 06.02.00 is attempted, but you can continue with the downgrade if desired.

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 tim e-out leaving the switch with the previous version of ﬁrmware.

HAFM upgrade required for ﬁrmware version 07.xx.xx

To upgrade to ﬁrmware 07.01.02-4, you must ﬁrst upgrade the HA FM 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. This HAFM upgrade is also available on the following HP web site: h

ttp://h18006.www1.hp.com/storage/saninfrastructure.html

Page 15

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 07.01.02-4 ﬁrmware, but to be able to use a ll the new features and enhancements, you need to upgrade HAFM to 08.06.00, which runs only on the 1U rack-mount HAFM appliance.

As an alternative, you can perform the ﬁrmware upgrade directly to the director or edge switch using their EWS.

Please contact your local HP technical resource if you need to obtain a new HAFM version.

Please contact your local H P 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 d etailed in the accompanying manuals listed in section Other edge switch documentation.

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 devic unavailable, RSCNs are sent only to the devices in the same zone. Zoning changes, however, trigger RSCNs to be sent to all of the devices in the fabric. As fabrics grow larger and larger, the quantity of RSCNs from zoning changes can create congestion and disrupt devices, causing them to pause normal activity to determine the status of the other devices. This can occur even if the new device is not zoned to talk to the other devices in the fabric.

Edge Switch release notes

Page 16

TheZoneFlexParfeatureisavailableinbothOpenFabric1.0andHomogeneous 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 sw itch. When upgrading to ﬁrmware 07.01.02-4 or installing anewswitchwithﬁrmware 07.01.02-4 the feature is enabled by default, allowing it to work immediately. If the Zone FlexPar feature is not enabled on all switches in the fabric, the restricted RSCN distribution only applies for devices attached to switches with the feature enabled.

Enhanced SAN

Standard features

The following SANtegrity features do not require a license or SANtegrity Binding.

• CHAP Authentication for HAFM/SWAPI—Thisprovidesauthenticationof

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. This prevents “snooping” of Ethernet conne ction 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 07.01.02-4 allows users to conﬁgure settings for using a RADIUS server. RADIUS provides centralized authentication services for multiple devices on a network. This means that several switches can be conﬁgured to use a single RADIUS server.

• Prompted Change of EWS and CLI Passwords from Default—This prompts users

to modify the password settings for both the CLI and EWS interfaces the ﬁrst time they log in using either of these interfaces.

• 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 inter faces. Multiple users c an 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.

curity Suite enhanced features include authentication support for device

switch connections and management interfaces. The Secure Access features

Page 17

• 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.

• Security Log—TheSecurityLogisanewlogavailableinEWS,CLI,andHAFM

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/tim e 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. This log provides customers with details to track down attempted security threats and identify the source of problems that might jeopardize the switch integrity.

• 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. This is primarily intended for environments that are not on a private, inaccessible subnet, such as when installed in m ost cabinet conﬁgurations with a dual-NIC HA FM appliance Processor.

ISL fencing

Also called Port Fencing, this feature a llows customers to set up policies for blocking an ISL when problems occur that cause an ISL to “bounce” or repeatedly attempt to establish a connection. Any time an ISL is brought up or down, a fabric rebuild occurs, whichcancausedisruptioninsomeenvironments. ISLFencingwilllessenthelikelihood of having a problematic ISL connection disrupt a SAN.

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 notiﬁ ed. Transmit and receive trafﬁc is disabled until the user can investigate, solve the problem, and manually unblock the por t.

Embedded Audit

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 p roblems caused by conﬁguration changes.

Embedded Port Log

The Embed ded Port Log is a new log that records all Fibre Channel trafﬁcfromorto 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 speciﬁceventsorproblems.

This feature is intended for advanced users to diagnose and troubleshoot trafﬁcproblems withinaSAN.TheEmbeddedPortLogisavailableviaEWS,CLI,andHAFM.

OSMS change

Open Systems Management Server (OSMS) is now available as a standard feature. OSMS can be enabled/disabled via EWS, Command Line Interface (CLI), and HAFM.

Default zone is disabled by default

ThedefaultzoneontheEdgeSwitch2/12,EdgeSwitch2/24,andEdgeSwitch2/32 is disabled by default. Zoning must be conﬁgured in order for any devices connected to the edge switches to communicate.

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 H AFM 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 05.01.00-24 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. All HP-approved host bus adapters (HBAs) limit access to devices within their zones, so you will not see a c zoning improves security against intruders that load nonstandard HBA drivers.

Hard zoning is compatible with legacy zone deﬁnitions, including World Wide Name (WWN) and por t 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 p ractice, modify your documentation, or retrain Storage Area Network (SA

Normally, when a zone set is activated, a fabric format domain Register State Change Notiﬁcation (RSCN) is sent to all devices in the fabric. With ﬁrmware 05.00.00 or later, you can disable these RSCNs from being sent. This is done using the Suppress RSCNs on zone set activations check box on the Conﬁg ure Switch Parameters dialog box.

SNMP c

This feature signiﬁcantly changes the normal behavior of the fabric. Devices will have no warning when zones change and will not automatically update their zoning information. The ability to suppress RSCNs is disabled (check box is not selected) by default. This feature can be conﬁguredthroughHAFM,EWS,andCLI.

Reinstalling feature licenses

Feature licenses (or keys) must be reinstalled after performing a factory reset on a director to regain use of the licensed features (e.g., SANtegrity Binding).

Disconnecting the null modem cable

Always log out and disconnect the null modem cable from the serial maintenance port when not in use or when the switch is reset.

Full Volatility

Full Volatility is an optional feature of ﬁrmware 06.00.00 and later that is enabled with a feature key. The Full Volatility feature is designed to support high-security

envi

ector after power off.

dir

Edge Switch release notes

Page 22

The feature conﬁgures a switch or director so that no frame data is stored a fter a power off. Without Full Volatility, if the switch or director experiences a fault condition, a dump of the embedded m emory space is captured into nonvolatile memor y. 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. Although this limits the amount of diagnostic information available for potential problem resolution, the vast majority of problems are typically resolved without the dump ﬁles.

Contact your sales representative to purchase a feature key for Full Volatility.

Path support

With ﬁrmware 07.00.00 and later, this allows users who a re not using HAFM to conﬁgure preferred data paths through the EWS interface. A preferred path is an ISL data path between multiple fabric elements (directors and switches) that users can conﬁgure using the source and exit ports of the origination fabric element, and the domain ID of the destination fabric elem ent.

With ﬁrmware 07.00.00 and later, this allows users to save switch conﬁguration settings toastandardXMLformatﬁle, 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. In the interim, you can use the complimentary CBR utility to restore conﬁgurations settings.

BB_Credit Allocati

on for ports

With ﬁrmware 07.00 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. For the Director 2/64, Director 2/140, and Edge Switch 2/32 switches, this enhancement simply allows more granular conﬁguration options for users who want complete conﬁguration control.

NVRAM caching

All writes to non-volatile memor y random access memor y (NVRAM), which stores conﬁguration data, are now cached to prevent possible corruption of information. Prior to ﬁrmware 07.00.00, a small window existed where a switch power-down during an NVRAM write could enable the conﬁguration default settings when the switch is powered back on. All switches and directors are now protected from potential interruptions to NVRAM updates.

Robust large fabrics

Numerous low-level enhancements and optimizations have been made to improve the stability

of directors and switches in fabrics containing high populations of devices.

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,isposted.

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 D efault Zone. This enhancement limits the number of members allowed in the Default Zone to

64. When the ﬁrmware detects a zoning operation that would cause the member count

in the Default Zone to exceed 64 (such as deactivating a n active zone set that has more than 64 members), the operation is aborted and the user interface (HAFM 8.6 or EWS)

plays the following message: Zoning request denied: Operation will

dis

cause the Default Zone to exceed its limit of 64 members.

Edge Switch release notes

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 oftheactiveports.

The feature key includes distance support. With ﬁrmware 06.00.00 and later, the Edge Switch 2/12 ships standard with ﬁve buffer-to-buffer (BB) credits allocated to each port. After activation of the Full Fabric feature on a switch, every port has 12 BB Credits allocated to support up to 12 km links at 2Gb/s speeds.

Hard zoning for Edge Switch 2/12 and Edge Switch 2/24 switch loop ports

Firmware 06.00.00 and later extends Hard Zoning to loop (FL) ports on Edge Switch 2/12 and Edge Switch 2/24. Previously, zoning on FL ports was regulated in software.

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 num erous fabric log in (FLOGI) requests, which are rejected by the Edge Switch 2/24. Processing these exchanges may increase fabric response times for activities such as fabric builds and valid FLOGI response time for other ports.

Workaround

Remove the unauthorized device, change the Port Binding WWN (if this device should be authorized), or alternatively, disable Port Binding.

HSG80 transparent mode not supported with IBM AIX

Use of an HSG80 with I BM AIX is restricted to operating the HSG80 in Multibus mo de with the Edge Switch 2/12, Edge Switch 2/24, and Edge Switch 2/32. Transparent mode is not supported at this time.

Page 25

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 m ode 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.

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 d etected this incident. The fabric operation or data m ovement is not disrupted by these incidents, and you can clear alerts from these incidences using the following procedure.

Workaround

Use these steps to clear the incident alerts.

1. At the HAFM H

2. Right-click on the port with the yellow triangle icon, and choose C l ear Link Incident

Alert(s).

ardware View, click the port module to open the Port Card View.

Support for speed Auto-Negotiate

Auto-negotiate is supported. However, HP recommends that the port speed for E_Ports (for Interswitch Links, or ISL s ) be set to a speciﬁcportspeed(1Gb/sec or 2Gb/sec,as appropriate for the speed of the directors or edge switches being connected) instead of to Negotiate.Usingaspeciﬁc port speed decreases the time for a fabric build in response to some perturbation event in the fabric. Similarly, setting a speciﬁcportspeed for N_Ports also decreases fabric b uild time. However, setting a speciﬁcportspeedfor N_Ports is not required.

There are a few older HBA devices that do not always succeed in logging in to a switch port when the port speed is set for auto-negotiate.

Edge Switch release notes

Page 26

Workaround

If an older HBA has difﬁcultyloggingintoaswitchportthathasitsportspeed conﬁgured as Negotiate,conﬁgure that port speed to 1Gb/sec or 2Gb/sec according to the operation speed of the H BA connected to that por t.

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 sequ ence, 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. This condition occurs because the I P address assigned to the edge switch or director has been reset to the factory default value (10.1.1.10).

Workaround

If this cond and the IP a by entering the license keys again.

ition occurs, the conﬁguration of the edge switch or director must be restored,

ddress must be restored. Also, all licensed features need to be reactivated

SNMP issues

SNMP traps warmStart and coldStart are not always received across Ethernet switches.
