This publication is part of a document suite that supports the Hewlett-Packard (HP) StorageWorks Director 2/64, Director 2/140, Edge Switch 2/16, Edge Switch 2/32, Edge Switch 2/24, and the Embedded Web Server (EWS) application.

Intended Audience

This book is intended for use by data center administrators, LAN administrators, operations personnel, and customer support personnel who administer user access to this application and monitor and manage product operation.

Suggested Reading

A book that can help you to prepare to install products and configure a SAN is the hp StorageWorks SAN high availability planning guide (620-000124/AA-RS2DB-TE).

You can obtain this book from the Hewlett-Packard website ( from the CD shipped with the Hewlett-Packard product you purchased.

Another publication you may want to read is Compaq StorageWorks SAN Switch Zoning Reference Guide, which is a white paper on zoning fundamentals. It is available online from the Hewlett-Packard website (

(http://thenew.hp.com) or

(http://thenew.hp.com).

1–6 embedded web server user guide

Where to Start

Depending upon whether the Hewlett-Packard product you purchased has already been installed, you may need to go to a specific chapter. If the product has not been installed, you should start at Chapter 2, Configuring the Product.

If the product was installed, then many of the configuration tasks were probably already completed. In that case, you may need to configure a zone. Configuring (including adding, deleting, and changing) zones is described in Chapter 3,

Configuring Zones.

If the products have been configured and you have a functioning SAN, then you most likely will be interested in performing system administration tasks. Those tasks are described in Chapter 4, Viewing Product and Fabric Data; Chapter 5, Monitoring

Products; and Chapter 6, Operating and Managing Products and Parts.

If you need to perform troubleshooting, then you will want to review Chapter 5,

Monitoring Products, and Chapter 6, Operating and Managing Products and Parts.

Introduction

Starting EWS

Open the EWS interface as follows:

1. Ensure the workstation (or device you use to launch the web browser) and the

Ethernet LAN segment containing the product, such as Edge Switch 2/24, are attached and connected through the Internet.

NOTE: You must be able to make a connection between the web browser and the

product in order to login to the product.

2. Launch the web browser application (such as Netscape Navigator, version 4.6 or

higher, or Microsoft Internet Explorer, version 4.0 or higher).

embedded web server user guide 2–1

Configuring the Product

Factory Default Values

HP products on a SAN have preset, default configuration values that were set in the factory. The items that have factory-set default values are:

• Passwords (customer and maintenance-level)

• Internet Protocol (IP) address

• Subnet mask

• Gateway address

The specific default values associated with a particular HP product are documented in the installation and service manual for the product.

Configuring Ports

Perform procedures in this section to configure names and operating characteristics for Fibre Channel ports. To configure one or more ports:

1. If you are going to change the Speed parameter on an Director 2/64, set the product offline as follows:

a. Choose Operations from the navigation panel. The Operations page

displays.

b. Click the Online State tab, then click Set Offline. The message Your

operations changes have been successfully activated

displays.

2. At the EWS screen, choose Configure from the navigation panel. The Configure page and the Ports tab view display (Figure 2–1 on page 2-3).

NOTE: Because the Director 2/140 has many ports, the listing of ports is divided into separate displays, which are accessed by clicking the hyperlinks 1-31, 32-63, 64-95, 96-127, and 132-143. If you make any changes to a particular list of ports, click Activate before selecting another list of ports. If you do not click Activate, changes are not implemented on the Director.

2–2 embedded web server user guide

Figure 2–1: Configure Ports tab view

Configuring the Product

a. For each port to be configured, type a port name of 24 alphanumeric

characters or less in the associated Name field. The port name should characterize the device to which the port is attached.

NOTE: When naming ports, you may want to name each port based on the device attached to the port. For example, if the port is attached to an e-mail server, you might name the port email1 server port 2. The important point is to relate the name of the port to the device that is attached to the port. If you have an installation with many products, you can have a large number of ports. Thus, it is helpful to give each port a name that you relate to the device connected to the port, which can help in isolating problems.

b. Click a check box in the Blocked column to block or unblock a port (default

is unblocked). A check mark in the box indicates a port is blocked. Blocking a port prevents the attached devices or HP products in the fabric from communicating. A blocked port continuously transmits the offline sequence (OLS).

c. Click the check box in the FAN column to enable or disable the fabric address

notification (FAN) feature (default is enabled). (The FA N column is available only on the Edge Switch 2/24.) A check mark in the box indicates FAN is enabled. When the feature is enabled, the port transmits a FAN frame after loop initialization to verify that Fibre Channel Arbitrated Loop (FC-AL) devices are still logged in. It is recommended this option be enabled for ports configured for loop operation.

embedded web server user guide 2–3

Configuring the Product

d. Click a check box in the 10-100 km column to define extended distance

buffering. (This column is not available on the Edge Switch 2/24.) A check mark in the box indicates extended distance buffering is enabled. You can enable extended distance for a port even if it is not an extended distance port. However, enabling extended distance buffering for a port disables the ability of the port to send broadcast traffic. When you choose this option, the port can support up to 60 buffer-to-buffer credits (BB_Credits) to handle link distances up to 100 km. This enables the port to process 2K frames from attached devices. If this option is not enabled, the port uses the BB_Credit value.

NOTE: If a device is connected and logged in to the fabric when extended distance is enabled or disabled on the corresponding port, the HP product sends OLS for 5 milliseconds to force the device to log in again and obtain the new BB_Credit value set for the port.

e. Choose from the drop-down list in the Type column to configure the port

type. Available selections are:

— G_Port — Generic port.

— F_Port — Fabric port.

— E_Port — Expansion port.

— GX_Port — Generic mixed port. Use this selection to configure a port as

a generic loop port (GL_Port). The port automatically negotiates any connection type (Edge Switch 2/24 only).

— FX_Port — Fabric mixed port. Use this selection to configure a port as a

fabric loop port (FL_Port). The port automatically negotiates F_Port and FL_Port connections only (Edge Switch 2/24 only).

f. Choose from the drop-down list in the Speed column to configure the port

transmission rate. Available selections are:

— Negotiate — Auto-negotiate between 1.0625 and 2.125 gigabits per

second (Gbps) operation. This is valid only on products that are capable of 2 Gb/sec operation.

— 1 Gb/sec — 1.0625 Gbps operation.

— 2 Gb/sec — 2.125 Gbps operation.

3. Click Activate to save and activate the changes. The message Your changes

to the port configuration have been successfully activated displays.

4. If the product is offline, set the product online as follows:

a. Choose Operations from the navigation panel. The Operations page

displays.

b. Click the Online State tab, then click Set Online. The message Your

operations changes have been successfully activated displays.

Configuring Product Identification

Perform this procedure to configure the HP product’s name, description, location, and contact person. The Name, Location, and Contact variables configured here correspond respectively to the SNMP variables sysName, sysLocation, and sysContact. These variables are used by SNMP management workstations when obtaining data from managed Edge Switches or Directors. To configure identification:

1. Choose Configure from the navigation panel. Choose the Switch or Director tab,

as appropriate. The Switch or Director tab displays with the Identification tab view (Figure 2–2).

ID uniquely identifies each product in a fabric.

NOTE: If the product is attached to a fabric element, the product and element must have unique domain IDs. If the values are not unique, the E_Port connection to the element cannot carry traffic and the product cannot communicate with the fabric.

2–8 embedded web server user guide

Configuring the Product

b. At the Insistent Domain ID field, choose Enabled or Disabled. When this

parameter is enabled, the domain ID configured in the Preferred Domain ID field becomes the active domain identification when the fabric initializes.

c. At the Rerouting Delay field, choose Enabled or Disabled. When this

parameter is enabled, traffic is delayed through the fabric by the specified error detect time out value (E_D_TOV). This delay ensures Fibre Channel frames are delivered to their destination in order, even if a change to the fabric topology creates a new (shorter) transmission path.

d. At the Domain RSCNs field, choose Enabled or Disabled. When this

parameter is enabled, messages can be sent between end devices in a fabric to provide additional connection information to host bus adapters (HBA) and storage devices.

4. Click Activate to save and activate the changes. The message Your changes

Figure 2–5: Fabric parameters tab view

a. At the BB_Credit field, type a value between 1 and 60. (This field is not

available for the Edge Switch 2/24.) Configure the product to support buffer-to-buffer credit (BB_Credit) from 1 through 60. This is the value used for all ports, except those configured for extended distance buffering (10-100 km). The default value is 16. For a description of the buffer-to-buffer credit, refer to industry specification, Fibre Channel Physical and Signaling Interface.

b. At the R_A_TOV field, type a value between 10 through 1200 tenths of a

second (1 through 120 seconds). (The R_A_TOV value must be greater than the E_D_TOV value.)

NOTE: If the product is attached to a fabric element, the product and element must be set to the same R_A_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric.

c. At the E_D_TOV field, type a value between 2 through 600 tenths of a second

(0.2 through 60 seconds). (The E_D_TOV value must be less than the R_A_TOV value.)

2–10 embedded web server user guide

Configuring the Product

NOTE: If the product is attached to a fabric element, the product and fabric element must be set to the same E_D_TOV value. If the values are not identical, the E_Port connection to the element fails and the product cannot communicate with the fabric.

d. Choose from the Switch Priority drop-down list to set the product priority.

Available selections are Default, Principal, and Never Principal. The default setting is Default.

This value designates the fabric’s principal switch. The principal switch is assigned a priority of 1 and controls the allocation and distribution of domain IDs for all fabric elements (including itself).

Principal is the highest priority setting, Default is the next highest, and Never Principal is the lowest priority setting. The setting Never Principal

means the switch is incapable of becoming a principal switch. If all switches are set to Principal or Default, the switch with the highest priority and the lowest World Wide Name (WWN) becomes the principal switch.

At least one switch in a fabric must be set as Principal or Default. If all switches are set to Never Principal, all interswitch links (ISLs) will segment, causing a failure of connectivity.

e. Choose from the Interop Mode drop-down list to set the product operating

mode. This option does not display if the Operation mode is S/390. (S/390 mode is not supported with the Edge Switch 2/24.) This setting only affects the mode used to manage the product; it does not affect port operation. Available selections are:

— Homogenous Fabric — Choose this option if the product is

fabric-attached only to other HP Directors or Switches operating in Homogenous Fabric mode.

— Open Fabric 1.0 — Choose this option for managing heterogeneous

fabrics and if the product is fabric-attached to HP Directors or Switches and open-fabric compliant switches produced by other original equipment manufacturers (OEMs).

Understanding Zoning

Designing zoning can be a complex task, especially for multiswitch fabrics. Consult with your managed product vendor’s professional services organization before configuring zoning.

This section is designed to help you understand the following concepts so that you can more efficiently use Embedded Web Server features to configure and manage zones across a multiswitch fabric:

• Benefits of zoning.

• How zoning works to control access to storage devices and servers across a fabric.

• Other methods of controlling access at the switch and at the server and device,

such as binding.

Configuring Zones

• Merging zoned fabrics.

• Basic concepts of zoning that you must deal with in configuring zoning such as

zones, zone sets, active zones, and default zones.

Controlling Access Across a Fabric

Embedded Web Server zoning features enable you to establish zoning across a fabric of devices attached to Switches and Directors by partitioning these devices into groups called zones. A zone is comprised of devices that can access each other through port-to-port connections. Devices in the same zone can recognize and communicate with each other; devices in different zones cannot.

System administrators create zones to increase security measures and prevent data loss or corruption by controlling access between devices (such as servers and data storage units), or between separate user groups (such as engineering or human resources).

embedded web server user guide 3–1

Configuring Zones

Zoning allows an administrator to:

• Establish barriers between devices that use different operating systems. For example, it is often critical to separate servers and storage devices with different operating systems because accidental transfer of information from one to another can delete or corrupt data. Zoning prevents this by grouping devices that use the same operating systems into zones.

• Create logical subsets of closed user groups. Administrators can authorize access rights to specific zones for specific user groups, thereby protecting confidential data from unauthorized access.

• Create groups of devices that are separate from devices in the rest of a fabric. Zoning allows certain processes (such as maintenance or testing) to be performed on devices in one group without interrupting devices in other groups.

• Allow temporary access between devices for specific purposes. Administrators can remove zoning restrictions temporarily (for example, to perform nightly data backup), then restore zoning restrictions to perform normal processes.

Figure 3–1 illustrates three zones established on a single managed product with four

devices in each zone. Devices in each zone can communicate with and access devices only in their respective zones.

Configuring Zones

Controlling Access at the Switch

A World Wide Name (WWN) binding feature is available on Switches and Directors that allows you to “bind” a specific Switch or Director port to the WWN of an attached device for exclusive communication.

NOTE: This WWN Binding feature can be configured through the HP HAFM Product Manager but not through the EWS.

Controlling Access at the Server or Storage Device

Features available at the server or storage device can add methods, beyond zoning, to increase network security measures, differentiate between operating systems, and prevent data loss or corruption by controlling access between devices or between separate user groups (such as engineering or human resources).

Server-level access control is called persistent binding. Persistent binding uses configuration information stored on the server and is implemented through the server’s host bus adapter (HBA) driver. The process binds a server device name to a specific Fibre Channel storage volume or logical unit number (LUN), through a specific HBA and storage port WWN. In essence, this feature creates a reliable route across the fabric that sustains the small computer system interface (SCSI) connection between a server and storage device.

For persistent binding:

• Each server HBA is explicitly bound to a storage volume or LUN, and access is explicitly authorized (access is blocked by default).

• The process is compatible with open system interconnection (OSI) standards. The following are transparently supported:

— Different operating systems and applications.

— Different storage volume managers and file systems.

— Different fabric devices, including disk drives, tape drives, and tape libraries.

• If the server is rebooted, the server-to-storage connection is automatically re-established.

• The connection is bound to a storage port WWN. If the fiber-optic cable is disconnected from the storage port, the server-to-storage connection is automatically re-established when the port cable is reconnected. The connection is also automatically re-established if the storage port is cabled through a different managed product port.

3–4 embedded web server user guide

Access can also be controlled at the storage device as an addition or enhancement to redundant array of independent disks (RAID) controller software. Data access is controlled within the storage device, and server HBA access to each LUN is explicitly limited (access is blocked by default). Storage-level access control:

• Provides control at the storage port and LUN level, and does not require

configuration at the server.

• Is typically proprietary and protects only a specific vendor’s storage devices.

Storage-level access control may not be available for many legacy devices.

Consult with your managed product vendor’s professional services organization before establishing persistent binding.

Consult with your managed product vendor’s professional services organization when establishing access control features at the storage device.

This chapter provides instructions for configuring zoning for single and multiple HP HAFM Directors and Switches in a multiswitch fabric.

Zoning Concepts

Configuring Zones

Zoning is configured by authorizing or restricting access to name server information associated with device ports that attach to product ports. A zone member is specified by the number of the product port to which a device is attached, or by the 8-byte WWN assigned to the host bus adapter or Fibre Channel interface installed in a device. A device port can belong to multiple zones.

Zoning concepts include:

•Zones

• Default Zone

•Zone Sets

•Active Zone Set

embedded web server user guide 3–5

Configuring Zones

Naming Conventions for Zones and Zone Sets

The following naming conventions apply to zones and zone sets:

• All names must be unique and may not differ by case only. For example, myzone and MyZone are both valid individually, but they are not unique.

• The first character of a zone set name must be a letter (A-Z, a-z).

• A zone set name cannot contain spaces.

• Valid characters are a-z, A-Z, 0-9, ^, -, _, and $.

• A zone set name can have a maximum of 64 characters.

Zones

A zone comprises a set of members that can access each other. Refer to Table 3–1 on

page 3-10 for details on the number of members that you can configure in a zone and

the number of zones that you can configure with the EWS Configure Zone functions.

A zone member can be a Switch or Director port or the WWN of the device. Ports and devices spread throughout multiple managed products in a multiswitch fabric may be grouped into the same zone. Members of a zone can see each other; members in different zones cannot. The number of members that you can configure for a zone varies according to the number of zones in the zone set, the length of the zone names, and other factors, but is essentially bounded by the available nonvolatile random-access memory (NVRAM) in the managed product.

NOTE: Port numbers cannot be used for zone members if the interoperability mode for the Switch or Director is set to Open Fabric 1.0 mode. In this case, you must use node WWNs as zone members.

The type of zone members identified for a zone may be mixed and matched. For example, two members may be specified by a port number and the third member by the WWN of the device.

3–6 embedded web server user guide

Configuring Zones

Using WWNs

To identify a zone member by WWN, use the 16-digit WWN of the device. For example:

10:00:08:00:88:40:C0:D4

In EWS the WWN displays with the Switch or Director manufacturer’s name before the WWN. The WWN is assigned to the Fibre Channel interface or HBA installed in devices such as servers or storage devices. Although the device may also have a node WWN, this WWN is not used for zoning identification.

NOTE: Nicknames can be assigned to the WWN using the HAFM Product Manager, not EWS.

The advantage of identifying a zone member as the WWN of the attached device is that the identification will not change if fiber cable connections to ports are rearranged. This is especially important if you are using spare ports. You can simply move the fiber cable to a spare port from a failed port and still maintain the zoning configuration.

The disadvantage of identifying a zone member by the WWN is that removal and replacement of a device HBA or Fibre Channel interface (thereby changing the device WWN) disrupts zone operation and may incorrectly include or exclude a device from a zone.

Using Port Numbers

To identify a zone member by port number, use the domain identification number of the managed product and the port number on that managed product. For example:

Domain 1, Port 1

NOTE: Port numbers cannot be used for zone members if the interoperability mode for the Switch or Director is set to Open Fabric 1.0 mode.

Port numbers can be 0 through n, with n representing the number of ports on the managed product minus one. When you define a zone member by a port number, any device attached through that port is included in the zone. A port number that you assign as a zone member is automatically prefixed with the domain identification number of the managed product.

The advantage of identifying a zone member by port number is that if the HBA on an attached device fails, you don’t have to identify the member with the WWN of the replacement HBA.

embedded web server user guide 3–7

Configuring Zones

A disadvantage of port zoning is that someone may rearrange cable connections to ports (because of port failures or other reasons) and inadvertently allow devices to communicate that should not have access to each other.

NOTE: If a managed product’s Domain ID changes, you must reconfigure all zones that contained the managed product’s port as a zone member. We recommend assigning unique Preferred Domain IDs to each switch in the fabric using the EWS Configure page, Switch,

Parameters tabs to change the Preferred Domain IDs.

Default Zone

A default zone consists of all devices that have not been configured as members of a zone in a currently-active zone set. Here are some important points to remember about zone sets:

• You can enable or disable the default zone separately from the active zone set by choosing the Zoning option from the Configure menu. Enabling the default zone allows all devices and ports not configured as members of the active zone set to communicate. If the default zone is disabled, these ports and devices cannot communicate.

• When no zone set is activated, then all devices are considered to be in the default zone.

• If a zone set is active, then all connected devices that are not included as a

Zone Sets

A zone set is a group of zones that you can activate or deactivate as a single entity across all managed products in either a single switch or a multiswitch fabric. Only one zone set can be active at one time. Devices that are members of zones in the zone set can only communicate with members of zones in the same zone set. However, devices can be included as members of more than one zone set. By activating a zone set, you are making all zones in the set active.

Refer to Table 3–1 on page 3-10 for details on the number of zones and zone members that you can configure in a zone set and the number of zone sets that you can configure.

Here are some important points to remember about zone sets:

• If no zone set is active, and the default zone is disabled, then no devices can

communicate.

3–8 embedded web server user guide

• If you activate a zone set when there is already an active zone set, that set will

replace the currently-active zone set.

• If you deactivate the current active zone set, then all devices connected in the

fabric become members of the default zone.

Active Zone Set

An active zone set is a zone set that is currently active on a single-switch fabric or across all managed products in a multiswitch fabric. At any time, you can disable zoning by deactivating the active zone set and enabling the default zone, or you can enable zoning by activating a zone set. When a zone set is active, all zones that are members of that zone set are active. Only one zone set can be active for the fabric at one time. If no zones are active, then all devices are considered to be in the default zone.

Merging Zoned Fabrics

Managed products are linked through Interswitch Links (ISLs) to form multiswitch fabrics. In a multiswitch fabric, the active zoning configuration applies to the entire fabric. Any change to the configuration applies to all switches in the fabric.

Configuring Zones

When fabrics join through an ISL, adjacent managed products exchange active zone configurations and determine if the configurations are compatible and can merge. Zoning configurations are compatible if the active zone names in each fabric are unique. If there are identical zone names in each fabric, then the zones must have identical members for the fabrics to join.

If the configurations can merge, the fabrics join. The resulting configuration will be a single zone set containing zone definitions from each fabric.

If configurations cannot merge, the expansion ports (E_Ports) on each product become segmented. Segmented E_Ports cannot carry traffic from attached devices (class 2 or 3 traffic), but can carry management and control traffic (class F traffic) between managed products.

Rules for Merging Zoned Fabrics

Certain rules are enforced to ensure that zoning is consistent across the fabric.

Table 3–1 summarizes rules for joining two fabrics through an ISL. The following

terms are used in the table:

• Not zoned — No zone set is active in the fabric and the default zone is enabled. In

other words, all devices in the fabric are visible to all other devices in the fabric.

embedded web server user guide 3–9

Configuring Zones

• Zoned — A zone set is active in the fabric and/or the default zone is disabled. In this case, devices can discover other devices that are members of the same zone.

• Zoning configuration — Combination of the active zone set definition and the default zone state (enabled or disabled).

active zone set will propagate across the fabric. Fabric B inherits zoning configuration from Fabric A.

Zoned Zoned Fabrics can merge if the zone names

in each fabric are unique. The resulting active zone set is a union of the zones from each fabric. Once you have merged the two zoned fabrics, click the Save active zone set as button in the Zoning view to save the active zone set.

If there is a zone name conflict (the same zone name in each fabric) then the zones must have identical members for the fabrics to join.

If the two zones have the same name but contain different members, then the E_Ports will segment and the fabrics will not join.

NOTE: If merging zones will result in segmented E_Ports and the fabrics will not join, you can join the fabrics by deactivating the active zone set on one of the fabrics (default zone is enabled). This eliminates any conflicts because the fabrics will then join using only the active zone set. After the fabrics join, you can make adjustments to zoning configurations as you desire.

Monitoring Products

Figure 5–2: Port Statistics tab view

Troubleshooting Tip for Port Stats

As a general rule, you should clear all the counters by choosing Clear Port Stats or Clear All Port Stats after you have resolved a problem. When troubleshooting, keep

track of the time interval when errors accumulate to judge the presence and severity of a problem. (There is a link recovery hierarchy implemented in Fibre Channel to handle some level of “expected anomalies.”) For troubleshooting purposes, you want to focus on when the errors, as displayed in the Counter column, increment very quickly.

Parts of Statistics Tables

The tables of statistics contain the following columns:

• Statistics — Type of statistic being tracked.

• # of Wraps — Number of times the Counter value wraps, for statistics that grow rapidly. The maximum value that either the Counter or the #ofWraps can hold

is 2

, or 4,294,967,296. Each time the Counter field reaches the maximum value

, the wrap count is incremented by 1.

of 2

• Counter — Number of instances of the tracked item recorded since system initialization or the last time the counters were cleared.

5–4 embedded web server user guide

Traffic Transmit and Receive Statistics

The Traffic Statistics include these transmit and receive values.

• Frames Rx — Number of frames that the port has received.

• Frames Tx — Number of frames that the port has transmitted.

• Four byte words Rx — Number of words that the port has received.

• Four byte words Tx — Number of words that the port has transmitted.

• Offline sequences Rx — Number of offline sequences (OLS) received by this

port.

• Offline sequences TX — Number of offline sequences (OLS) transmitted by this

port.

• Link resets Rx — Number of link reset protocol frames received by this port

from the attached N_Port.

• Link resets TX — Number of link reset protocol frames transmitted by this port

to the attached N_Port.

Monitoring Products

• Link utilization % Rx — Current link utilization for the port expressed as a

percentage. On 1 Gbps links, ports can transmit or receive data at 100 MB per second. On 2 Gbps links, ports can transmit or receive data at 200 MB per second. Link utilization is calculated over one-second intervals.

• Link utilization % TX — Current link utilization for the port expressed as a

percentage. On 1 Gpbs links, ports can transmit or receive data at 100 MB per second. On 2 Gbps links, ports can transmit or receive data at 200 MB per second. Link utilization is calculated over one-second intervals.

For the Edge Switch 2/24, the following statistics are also shown:

• LIPs Detected — A loop initialization primitive (LIP) was detected, which means

the loop was completed.

• LIPs Generated — A loop initialization primitive was created to initialize a loop.

• Discarded Frames — Number of Class 3 frames discarded (including multicast frames with bad Domain IDs).

• 4-byte words Rx — Number of Class 3, 4-byte words received by the port.

• 4-byte words TX — Number of Class 3, 4-byte words transmitted by the port.

Error Statistics

The Error Statistics include these transmit and receive values:

• Link failures — Number of link failures recorded because a not operational sequence (NOS), protocol timeout, or port failure was detected.

• Sync losses — Number of loss-of-synchronizations detected because an attached device was reset or disconnected from the port.

• Signal losses — Number of loss-of-signal errors detected because the attached device was reset or disconnected from the port.

5–6 embedded web server user guide

Monitoring Products

• Primitive sequence errors — Number of primitive sequence protocol errors

received from an attached device, which indicates a Fibre Channel link-level protocol violation.

• Discarded frames — A received frame could not be routed and was discarded

because the frame timed out due to an insufficient buffer-to-buffer credit, or the destination device was not logged into the product.

• Invalid transmission words — Number of invalid transmission words from an

attached device. This indicates that a frame or primitive sequence arrived at the port corrupted.

• CRC errors — A received frame failed a cyclic redundancy check (CRC)

validation, indicating the frame arrived at the port corrupted. Frame corruption may be caused by device disconnection, an optical transceiver failure at the device, a bad fiber-optic cable, or a poor cable connection.

• Delimiter errors — Number of times that the switch detected an unrecognized

start-of-frame (SOF), an unrecognized end-of-frame (EOF) delimiter, or an invalid class of service. This indicates that the frame arrived at the switch’s port corrupted. This corruption can be due to plugging/unplugging the link, bad optics at either end of the cable, bad cable, or dirty or poor connections. Moving the connection around or replacing cables can isolate the problem.

• Address ID errors — A received frame had an unavailable or invalid Fibre

Channel destination address, or an invalid Fibre Channel source address. This typically indicates the destination device is unavailable.

• Frames too short — A received frame exceeded the Fibre Channel frame

maximum size or was less than the Fibre Channel minimum size, indicating the frame arrived at the switch’s port corrupted. Frame corruption may be caused by device disconnection, an optical transceiver failure at the device, a bad fiber-optic cable, or a poor cable connection.
