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)—Theoretically, the ISL limit per

Director 2/64 is 32 and for Director 2/140 is 70. The maximum supported number

of ISLs per director is half of the director ports. For redundancy, at least two ISLs

should connect any two director-class fabric elements. Because this number is

subject to change, contact your HP authorized service representative for the

current number of ISLs supported per director.

• 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

director release notes 7

Cable Requirements

IMPORTANT: Please note that 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. 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 Director 2/64 and Director 2/140 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 Director 2/64 and

Director 2/140.

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 Director 2/64 and Director 2/140. Transparent mode is not supported at

this time.

Workaround

None.

Known Issues

8director 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.

Known Issues

director release notes 9

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

director to regain use of the licensed features (e.g., SANtegrity).

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.

Hot Insertion of an Optical Transceiver May Produce Port

Failure Event

There should be no impact to the switching and throughput capabilities of the director

and the error event can be cleared by performing a Port Reset.

Known Issues

10 director release notes

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.

Director Properties Description May Be Incorrect

The text shown in the Description field of the Director Properties panel for the

Director 2/140 may be incorrect. It may show SAN Director 64. This has no

effect on the operation of the Director 2/140. This is a user-configurable description

for the director, and may be changed to whatever you want by choosing Configure >

Identification using HAFM, or by choosing Configure > Director > Identification

using the Embedded Web Server interface.

IML Is Required After Performing a Configuration Reset

If a Reset Configuration is performed on a Director 2/140 to reset the director to

factory configuration, an initial machine load (IML) is required to be performed to

complete the process. This is done by pressing the white button on the front of either

CTP card for more than three seconds. This can also be accomplished by turning the

power to the Director 2/140 off, and then back on.
