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. 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 ISL limit per Edge Switch 2/24 is 24
and per Edge Switch 2/32 is 32. 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
IMPORTANT: Please note that optical cables for the edge switch 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 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.
Known Issues
This section describes the known issues related to the HP StorageWorks Edge
Switch 2/24 and Edge Switch 2/32.
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. Transparent mode is not supported at this time.
Workaround
None.

8edge 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.
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.

Updating an Earlier Version of Firmware
FW that predates the 1.3/1.4 FW release must first be updated to a 1.3 FW version or
higher before the final update to 2.00.00_33 or 2.00.02_1 can be completed.
Using the Same Firmware
All switches and directors managed by HAFM 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 a
switch to regain use of the licensed features (e.g., SANtegrity or additional flexports).
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 HBA's 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.
Hot Insertion of an Optical Transceiver May Produce Port
Failure Event
There should be no impact to the switching and throughput capabilities of the switch
and the error event can be cleared.

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.
