Supported Configurations
8Edge Switch Release Notes
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
switches in a single fabric is 31. The supported limit of interconnected
switches in a single fabric is 24. Because this number is subject to change,
contact your 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 all 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 7. The maximum
supported hop count in a single path through a fabric is 3. Because this
number is subject to change, contact your HP authorized service
representative for the current hop count supported by a single fabric path.
Note: 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
9Edge Switch Release Notes
Cable Requirements
Note: Please note that optical cables for the Edge Switch 2/24 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. 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 2/24 and Edge
Switch 2/32 use LC Duplex connectors with a PC finish. In addition, the
connector at the opposite end of the cable must use either LC or SC type,
depending on the requirements of the connected device.

Important Information
10 Edge Switch Release Notes
Important Information
This section describes important information related to the Edge Switch 2/24 and
Edge Switch 2/32.
HAFM and Firmware Version Compatibility
Table 1 lists the minimum version of HAFM that can run with the various versions
of firmware for the directors and edge switches.
Upgrading to an Earlier Version of Firmware
Upgrading to firmware version 05.01.00-24 is nondisruptive to attached devices.
The edge switch or director 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 edge
switch or director configuration in the event that a failure should occur. Refer to
the switch or director Product 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.
Before upgrading the Director 2/64 or Director 2/140 to version 05.01.00-24,
execute a CTP switchover to assure that the backup CTP card is fully functional.
Table 1: 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 06.00.00-45 (HP EFCM)
02.00.02-01 06.00.02-06
04.01.02-04 06.03.01-05
05.01.00-24 07.01.00-09

Important Information
11Edge Switch Release Notes
To execute a CTP switchover, perform the following steps:
1. From Product Manager Hardware view, verify that an amber LED indicator
does not display for either CTP card.
2. Right-click on a CTP card and choose Switchover from the menu.
Note: The switch or director will lose its Ethernet connection for a short period
during the switchover process.
3. Upgrade firmware to version 05.01.00-24.
All products must be running firmware version 04.00.00 or higher before
upgrading to version 05.01.00-24. If a switch or director is operating with a
firmware level below 04.00.00, you must upgrade to version 04.00.00 or higher
before installing version 05.01.00-24.
All products must be running version 02.00.00 or higher before upgrading to
version 04.01.02-04. Upgrading to version 04.01.02-04 from version 02.00.00 or
higher is nondisruptive to attached devices.
Firmware that predates the 01.03.00 or 01.04.00 firmware release must first be
upgraded to a 01.03.xx or 01.04.xx firmware version, and then upgraded to
version 02.00.00 or higher, before the upgrade to version 04.01.02-04 can be
completed.
Considerations for Downgrading the Version of Firmware
Directors and edge switches are not required to be offline before performing a
firmware 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
edge switch or director configuration in the event that a failure should occur. Refer
to the switch or director Product 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.
Downgrading directly to a version prior to 04.00.00 from version 05.01.00-24 is
not allowed. To downgrade to a version before 04.00.00, you must first downgrade
to version 04.YY.ZZ.

Important Information
12 Edge Switch Release Notes
Note: The Director 2/140 and Edge Switch 2/24 cannot be downgraded below
version 04.01.00.
Downgrading directly to a version prior to 02.00.00 from version 04.YY.ZZ is not
allowed. To downgrade to a version before 02.00.00, you must first downgrade to
version 02.YY.ZZ.
Firmware downgrades should not be performed using EWS and Microsoft®
Internet Explorer version 5.00.3315.1000x. If this operation is performed, the
download operation may not complete and may eventually time-out leaving the
switch with the previous version of firmware.
HAFM Upgrade Required for Firmware Version 05.01.00-24
If you are using the HAFM server to manage the Director 2/140, Director 2/64,
Edge Switch 2/32, Edge Switch 2/24, and/or Edge Switch 2/16, and they are
running firmware version 05.01.00-24, you need to upgrade HAFM to version
07.01.00-09 (minimum). 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 Edge Switch Documentation”.
Open Trunking Feature is Not Available in Current Release
The Open Trunking feature is not available in Firmware Version 05.01.00-24.
Open Trunking feature will be available in a future release.
Zoning is Disabled by Default
The default zone on the Edge Switch 2/24 and the Edge Switch 2/32 is disabled by
default. Zoning must be configured in order for any devices connected to the edge
switches to communicate.

Important Information
13Edge Switch Release Notes
Hard Zoning
Hard Zoning is a security enhancement in firmware version 05.01.00-24 that
prevents ports from accessing devices outside their zones. Hard Zoning is enabled
by default when using firmware version 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. There are no changes to the zoning interfaces, so you do not
need to modify your zone management practice, 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. A Class 2 frame will
be fabric rejected, and a Class 3 frame will be dropped.
Zoning Change RSCN Control
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
version 05.01.00-24. you can disable these RSCNs from being sent. This is done
using the Suppress RSCNs on zone set activations check box on the Configure
Switch Parameters dialog box.
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 configured through HA-Fabric Manager
(HAFM), Embedded Web Server (EWS), and the Command Line Interface (CLI).
Embedded Web Server (EWS) Changes
With firmware version 05.01.00-24. the EWS now provides support for
configuration of Port Binding. The zoning interface has also been enhanced to
allow you to easily add members to a zone that are not directly attached to the
locally managed switch. You are presented with a list of all devices that are logged
in to the fabric. You can select these devices for addition to a zone.

Important Information
14 Edge Switch Release Notes
Command Line Interface (CLI) Changes
CLI has been enhanced to provide the following benefits:
■Access to symbolic name information in the name server database.
■Counter Threshold Alerts (CTA)—Used to configure limits and alerts for
any of the supported port statistics fields. You can configure alerts for
individual ports, groups of ports, or various port types, based on
user-specified counter value exceeded over a specified time duration.
Note: The CTA configuration is cleared upon downgrade to firmware below
05.01.00.
SNMP Changes
Firmware version 05.01.00-24 supports the following management information
base (MIB) versions on all products:
■Fabric Element MIB: V1.1
■MIB-II MIB: RFC-1213, non-implemented sections are not included
■FCEOS MIB: V2.0
■SNMP Framework MIB: RFC-2271 (1997/09/30)
■FA MIB: V3.1
Zoning Limitations
Firmware version 05.01.00-24 includes the ability to configure large zone sets,
including up to 1024 zones and 1024 end ports in a single zone set. Table 2 shows
the supported limits for the edge switches and directors.
Note: Hard Zoning will be enforced upon firmware initialization. Devices not
conforming to zoning rules will be restricted to their assigned zones.

Important Information
15Edge Switch Release Notes
Table 2: Zoning Parameters Supported Limits
Note: The supported number of zones is based on a zone name with a maximum of
32 characters. On all edge switches and directors except the Director 2/140, the
maximum number of zones decreases if full 64 character names are used. The
supported limits are based on two members per zone.
Zone set sizes are affected by the number of zones in the zone set, the length of
each zone name, the number of members in each zone, and the Interoperability
mode of the fabric. Please consult with HP Professional Services or your support
representative if you have questions regarding specific zone set configurations.
Using the Same Firmware
All switches and directors in the same fabric should have the same FW level
installed—whether 1 Gbps or 2 Gbps capable.
Reinstalling Feature Licenses
Feature Licenses (or keys) must be reinstalled after performing a factory reset on
an edge switch to regain use of the licensed features (e.g., SANtegrity Binding).
Zoning Parameter Maximum Value
Number of end ports 1024
Unique zone members 1024
Members per zone 1024
Zones 1024
Number of zone sets 64
Maximum devices supported 1024

Known Issues
16 Edge Switch Release Notes
Known Issues
This section describes the known issues related to the Edge Switch 2/24 and Edge
Switch 2/32.
Embedded Web Server access to modify zones is limited to first 255
zones
If you have an active zone set of greater than 255 zones, you will not be able to
access the zones past the 255th zone using the Embedded Web Server (EWS). The
higher number zone names are listed, but when accessed to modify the zone (for
example, the zone that would be numbered “n”), you will get the zone member list
for the (n-255) zone. This will be corrected in a future firmware release.
Workaround
Using the HAFM server to manage directors and edge switches will allow you to
modify zones in zone sets with greater than 255 zones.
SNMP trap reports incorrect FRU position
When an SNMP trap is sent and reports a FRU position number, the reported
number is one greater than the actual FRU position that caused the SNMP trap to
be issued.
Workaround
None.
Some IP Addresses must be Avoided
When you select IP addresses for edge switches and directors, and also if you
select a static IP address for the HAFM server, 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 server. Using an IP address in this range causes the call-home feature
to function incorrectly.

Known Issues
17Edge Switch Release Notes
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 numerous fabric login
(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.
CTP Events for Edge Switch 2/24 Show Incorrect FRU Number
Should a CTP event occur in an Edge Switch 2/24, the event log may show
“CTP-24” instead of “CTP-0”. There is only one CTP in the Edge Switch 2/24, so
there should be no question as to what FRU is exhibiting the event.
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 Edge Switch 2/24 and Edge Switch 2/32. Transparent mode is not
supported at this time.
Workaround
None.

Known Issues
18 Edge Switch Release Notes
HSG80 Transparent Mode Not Recommended with Controller in SCSI-3
Mode with HP-UX Operating Systems
Due to an issue with non-existent 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, Version 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 server 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. The fabric
operation or data movement is not disrupted by these incidents, which can be
cleared using the following procedure.
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).
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.

Known Issues
19Edge Switch Release Notes
Multiple FC HBA Ports in Separate Zones
Multiple FC HBA ports in the same host should be placed in separate zones, or
they might be perceived as potential targets (some HBAs log-in as both host and
target).
CTP Controls Port Lights
Port lights on the edge switch and director products are controlled by the CTP
functionality. Certain activities such as FW updates, IPLing the CTP, or switching
over to the backup CTP (Director) can cause these port lights to extinguish
momentarily until control is reasserted by the CTP. The actual FC traffic is not
affected during these times.
Support for Speed Auto-Negotiate
Currently, Speed Auto-Negotiate is not supported for HA and Failover SAN
configurations and is not recommended in general at this time. The speed should
be hard set to match the attached host or target port capability whenever possible.
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 will correct the problem.
