1 An introduction to Fabric Watch

This chapter contains the following information:

• Fabric Watch overview, page 11

• Introduction to fabric health, page 12

Fabric Watch overview

Fabric Watch is an optional Storage Area Network (SAN) monitoring software for B-Series HP StorageWorks switches running Fabric OS 2.2 or higher. It enables each switch to constantly watch its SAN fabric for potential faults and to automatically alert you to problems long before they become costly failures.

Fabric Watch tracks a variety of SAN fabric elements, events, and counters. Monitoring fabric-wide events, ports, GBICs, and environmental parameters enables early fault detection and isolation as well as performance measurement. You can select custom fabric elements and alert thresholds or choose from a selection of preconfigured settings. You can also easily integrate Fabric Watch with enterprise systems management solutions.

By implementing Fabric Watch, you can rapidly improve SAN availability and performance without installing new software or system administration tools.

For a growing number of organizations, SAN fabrics are a mission-critical part of their systems architecture. These fabrics can include hundreds of elements, such as hosts, storage devices, switches, and inter-switch links (ISLs). An instrumentation solution for SANs delivers optimal value by tracking a wide spectrum of fabric events. For instance, Fabric Watch monitors:

• Fabric resources, including fabric reconfigurations, zoning changes, and new logins.

• Switch environmental functions such as temperature, power supply, and fan status, along with security

violations.

• Port state transitions, errors, and traffic information for multiple port classes as well as operational

values for supported models of “Smart” GBICs/SFPs.

• Performance information for AL_PA, end-to-end, and SCSI command metrics.

Fabric Watch lets you define notification thresholds. Whenever fabric elements exceed these thresholds, Fabric Watch automatically provides notification using several methods, including email messages, SNMP traps, and log entries.

Fabric Watch provides the following two types of automatic notifications:

• A continuous alarm provides a warning message whenever a threshold is breached; it continues to

send alerts until the condition is corrected. For example, if a switch exceeds its temperature threshold, Fabric Watch activates an alarm at every measurement interval until the temperature returns to an acceptable level.

• A triggered alarm generates the first warning when a threshold condition is reached and a second

alarm when the threshold condition is cleared.

Fabric Watch provides event notifications in several different formats to ensure that event details are accessible from all platforms and operating systems. In response to an event, Fabric Watch can record event data as any (or all) of the following:

• Simple Network Management Protocol (SNMP) trap

Following an event, Fabric Watch transmits critical event data as an SNMP trap. Support for SNMP makes Fabric Watch readily compatible with both network and enterprise management solutions.

• Event log entry

Following an event, Fabric Watch adds an entry to the internal Event Log for an individual switch, which stores up to 1024 error messages.

• Lock port log

Fabric OS 5.x Fabric Watch administrator guide 11

Following an event, Fabric Watch adds an entry to the internal port log for an individual switch and freezes the log to ensure that detail-level information is available.

• RapiTrap

Following an event, Fabric Watch forwards event information to a proxy switch, which then forwards the information to a server to notify you.

• Email notification

Following an event, Fabric Watch creates and sends an Informational email to a designated recipient.

Fabric Watch is designed for rapid deployment. Simply enabling Fabric Watch permits immediate fabric monitoring. Fabric Watch is also designed for rapid custom configuration. You can easily create and modify configuration files using a text editor and then distribute configurations to all the switches in the SAN through the Fabric OS configuration management utility. Fabric Watch also comes with preconfigured profiles for rapid implementation.

Introduction to fabric health

Fabric health refers to the capability of the fabric to support data to be routed through it. A healthy fabric enables effective data transmission between networked devices.

Although the concept of fabric health initially seems fairly simple, it can be a deep and complex topic due to the number of factors that are involved. One of the more obvious criteria for fabric health is the condition of the network hardware. A switch or port failure could easily prevent data packets from reaching their destination. Network traffic can also influence fabric health.

If the number of packets routed through a port exceeds the port bandwidth, it causes network delays and packet losses. Even environmental factors can become issues, as network hardware can fail to function properly when stored in locations that do not meet the environmental conditions for the device. For example, switches can fail when stored in rooms that are too hot.

Because of the varied and complex factors in determining fabric health, you need fabric monitoring software such as Fabric Watch to help you to quickly detect, identify, and resolve fabric health issues by continuously monitoring possible issues and reporting any potential concerns. Fabric Watch automatically provides detailed reports on detected issues and helps you correct failures.

Fabric Watch provides customizable monitoring thresholds. You can configure Fabric Watch to provide notification before problems arise, such as reporting when network traffic through a port is approaching the bandwidth limit. This information enables you to perform preemptive network maintenance such as trunking or zoning and avoid potential network failures.

Fabric watch components

Fabric Watch uses a hierarchical organization to track the network device information it monitors. There is a class, area, and element associated with every monitored behavior. Classes are the highest level in the system, subdivided into one or more areas. Areas contain one or more elements.

The following sections explain this hierarchy and its application within Fabric Watch.

Classes

Classes are high-level categories of elements. Classes are intentionally wide groupings of similar fabric devices or fabric data.

Examples of classes include Port (which includes all physical ports on a switch), Security (which includes information related to unauthorized login attempts), and Environment (which contains information related to the room temperature, supplied power and fan assemblies).

In some cases, classes are divided into subclasses. This additional level in the hierarchy increases the flexibility of setting monitoring thresholds. You can use subclasses to add additional event monitoring to fabric objects that meet the requirements of a subclass.

For example, ports connected to another switch can be monitored using both the Port class and E_Port subclass. You can configure general port monitoring using the Port class and monitoring specific to a type of port using the E_Port class. Ports connected to another switch can trigger events based on either of these configurations. Ports that are not connected to another switch are not affected by the additional monitoring configured into the E_Port class.

Table 2 describes the classes into which Fabric Watch groups all switch and fabric elements.

Table 2 Fabric Watch classes

Class Description

Environment Includes information about the physical environment in which the

switch resides and the internal environment of the switch. For example, an Environment-class alarm alerts you to problems or potential problems with temperature and power.

Fabric Groups areas of potential problems arising between devices,

including interswitch link (ISL) details, zoning, and traffic. A Fabric-class alarm alerts you to problems or potential problems with interconnectivity.

Field Replaceable Unit (FRU)

Monitors the status of FRUs and provides an alert when a part replacement is needed. This class monitors states, not thresholds.

Class Description

Performance Monitor Serves as a tuning tool. Performance Monitor classes group areas

that track the source and destination of traffic. Use the Performance Monitor class thresholds and alarms to determine traffic load and flow and to reallocate resources appropriately.

The Performance Monitor class is divided into the areas AL_PA Performance Monitor, EE (end-to-end) Performance Monitor, and Filter Performance Monitor.

Port Enables you to set additional thresholds, specific to different types of

ports. The Port class is divided into separate classes: E_Port class—Represents ports connected to another switch. F/FL_Port class —Represents fabric or fabric loop ports that are

made of copper or optical fiber.

Resource Monitors flash memory. It calculates the amount of flash space

consumed and compares it to a defined threshold.

Security Monitors all attempts to breach your SAN security, helping you

fine-tune your security measures.

Elements

Area Description

Transmit Power The transmit power area measures the amount of outgoing laser, in

µwatts. Use this to determine the condition of the SFP. If the counter often exceeds the threshold, the SFP is deteriorating.

Current The current area measures the amount of supplied current to the SFP

transceiver. Current area events indicate hardware failures.

Supply Voltage The supply voltage area measures the amount of voltage supplied to the

SFP. If this value exceeds the threshold, the SFP is deteriorating.

Fabric Watch defines an each area, there are a number of elements equivalent to the number of components being monitored. For instance, in the Core Switch 2/64, each area of the Port class will include 64 elements.

Each element contains information pertaining to the description suggested by the area. To continue the Ports example, each element in the Invalid word area of Ports would contain exactly 64 ports, each of which would contain the number of times invalid words had been received by the port over the last time interval. Each of these elements maps to an index number, so that all elements can be identified in terms of class, area, and index number. As an example, the monitoring of the temperature sensor with an index of one may be viewed by accessing the first temperature sensor within the temperature area of the environment class.

Subclasses are a minor exception to the above rule. Subclasses, such as E_Ports, contain areas with elements equivalent to the number of valid entries. Within the same example used thus far in this section, in a 64-port switch in which eight ports are connected to another switch, each area within the E_Port class would contain eight elements.

Each area of a subclass with defined thresholds will act in addition to the settings applied to the element through the parent class. Assignment of elements to subclasses does not need to be performed by a network administrator. These assignments are seamlessly made through automated detection algorithms.

Configuring events

The following area attributes are used to define and detect events in Fabric Watch:

• ”Event behavior types” on page 19

• ”Data values” on page 20

• ”Threshold values” on page 20

• ”Time bases” on page 21

• ”Event settings” on page 23

element

as any fabric or switch component that the software monitors. Within

You can customize the information reported by Fabric Watch by configuring event behavior types, threshold values, time bases, and event settings. You cannot change data values; these represent switch behavior that is updated by the software.

Event behavior types

Based on the number of notifications delivered for events there are two categories of event behavior types:

• ”Continuous event behavior” on page 19

• ”Triggered event behavior” on page 20

Continuous event behavior

Areas with event behavior types set to longer meets the criteria defined for the event.

For example, you can configure Fabric Watch to notify you during every sample period that a port is at full utilization. This information can help you plan network upgrades.

continuous

trigger events in every sample period until the fabric no

Fabric OS 5.x Fabric Watch administrator guide 19

Triggered event behavior

If you do not want notification during each sample period from the port hardware failure to the time of its repair, you can define the event behavior as

When an event behavior is defined as triggered, Fabric Watch sends only one event notification when the fabric meets the criteria for the event. It does not send out any more notifications.

For example, when a port fails, Fabric Watch sends you a notification of the failure. After you repair the port, Fabric Watch detects the repair. At this time, Fabric Watch determines that the fabric no longer meets the event criteria, and watches for the error again. The next time the port fails, it sends you another notification.

Data values

A data value represents an aspect of a fabric in three ways: counter value, measured value or state value. Data values are updated by Fabric Watch approximately every six seconds. You cannot change them.

Counter value is the total number of times that a given event has occurred. For each monitored event during the time period, the value is incremented.

Measured value is the current, measurable value of a fabric or fabric element, such as environmental temperature or fan speed.

State value, which is the only qualitative data value, provides information on the overall state of a fabric component, such as the physical health of a fan. Instead of numerical data, state values contain information on whether components are faulty, active, or in another state.

Fabric Watch compares counter values and measured values to a set of configurable limits to determine whether fabric monitoring has occurred and whether to notify you. You must set appropriate threshold boundaries to trigger an event.

triggered

.

State values are handled differently, as Fabric Watch monitors state values for certain states, which you can select. When a state value transitions to one of the monitored states, an event is triggered.

Threshold values

Threshold values are of the following types:

• ”High and low thresholds” on page 20

• ”Buffer values” on page 20

High and low thresholds

High and low threshold values are the values at which potential problems might occur. For example, in configuring a temperature threshold, you can select the temperatures at which a potential problem can occur due to both overheating and freezing.

You can compare high and low thresholds with a data value. The units of measurement are the same as that of the associated data.

Buffer values

You can use buffer values to reduce the occurrence of events due to data fluctuation. When you assign a buffer value, it is used to create a zone in which events cannot occur both above the high threshold and below the low threshold.

20 Fabric Watch concepts

Figure shows an example in which each time a signal crosses the high limit, an event occurs. The blue

arrows indicate the area where the event criteria is met. In this case, there is a great deal of fluctuation. Even when the monitor is set to triggered, a number of messages are sent.

Figure 1 Threshold monitoring

Figure shows how to limit the number of event notifications using a buffer. When you specify a buffer,

events cannot occur both above the high threshold and below the low threshold. Event notification occurs only where the arrow indicates. The event criteria is continued to be met until the data sensed falls below the high threshold value.

Figure 2 A buffered data region

Time bases

Time bases are time periods within Fabric Watch. This configurable field impacts the comparison of sensor-based data with user-defined threshold values.

Setting time base to none

If you set a time base to When the absolute value of the measuring counter exceeds the threshold boundary, an event is triggered.

Figure shows a high limit of 65 degrees Celsius placed on a counter measuring temperature. During each

sample period, Fabric Watch measures the temperature is measured and compares it against the high threshold. If the measured temperature exceeds the high threshold, it triggers an event.

none

, Fabric Watch compares a data value against a threshold boundary level.

Figure 3 Time base set to none

Fabric OS 5.x Fabric Watch administrator guide 21

Specifying a time base

If you specify a time base value other than the current data value. Instead, it calculates the difference between the current data value and the data value as it existed one time base ago. It compares this difference to the threshold boundary limit.

For example, if you specify the time base between two samples a minute apart. It then compares the difference (current data value – data value one minute ago) against the preset threshold boundary.

When you set a time base to a value other than configuring events:

• Fabric Watch triggers an event only if the difference in the data value exceeds the preset threshold boundary limit.

• Even if the current data value exceeds the threshold, Fabric Watch does not trigger an event if the rate of change is below the threshold limit.

The following examples illustrate each point.

Example1: Triggering an Event

Figure shows a sample graph of data obtained by Fabric Watch (the type of data is irrelevant to the

example). A high threshold of 2 is specified to trigger an event. A time base of occurs only if the rate of change in the specific interval (one minute in this example) is across the threshold boundary. It should be either higher than the high threshold limit or lower than the low threshold limit. As illustrated on the tenth sample, the counter value changes from 0 to 1; hence calculated rate of change is 1 per minute. At the thirteenth sample, the rate of change is 2 per minute. The rate of change must be at least 3 per minute to exceed the event-triggering requirement of 2, which is met on the eighteenth sample.

Example 2: Not Triggering an Event

Figure uses the same data to illustrate a case in which a threshold is exceeded without triggering an event.

In this case, the calculated rate of change in the data value is always less than or equal to the high threshold of 2. At the tenth sample, the rate of change is one per minute. At the fourteenth, twenty-first, and twenty-fifth sample, the rate of change remains equal to the high threshold of 2. In this case, Fabric Watch

does not trigger an event even though the absolute value of the counter reaches 4, which is well above the high threshold.

Figure 5 Example without an event

Event settings

This section describes how Fabric Watch compares a fabric element’s data value against a threshold value to determine whether or not to trigger an event. It describes how a specified buffer zone impacts event triggering.

Fabric Watch monitors data values for one of the following conditions:

• ”Above event triggers” on page 23

• ”Below event trigger” on page 24

• ”Changed event trigger” on page 24

• ”In-Between triggers” on page 24

For Fabric Watch to monitor these conditions, the alarm setting must be set to a non-zero value.

Above event triggers

Use the Above event trigger for an element that requires only high threshold monitoring. In the Above event trigger, Fabric Watch triggers an event immediately after the data value becomes greater than the high threshold.

Define a buffer zone within the operational limit of an area to suppress multiple events when the counter value fluctuates above the high threshold and buffer zone. Figure shows an Above event trigger with a buffer zone.When a buffer is used, the data value must be greater than the sum of the high threshold and the buffer value (event 1 in Figure ). When the data value becomes less than the high threshold again, Fabric Watch triggers a second event (event 2) to indicate that it has returned to normal operation.

Figure 6 Above event trigger with buffer zone

Fabric OS 5.x Fabric Watch administrator guide 23

Below event trigger

The Below event trigger generates an event when a data value becomes less than the low threshold boundary.

When a buffer is defined, the data value must be below the buffer value and the low threshold.

Changed event trigger

Use the Changed event trigger for an element that requires “rate of change” monitoring. When Fabric Watch detects a change in the counter value between two sample periods (defined by the time base), it triggers an event regardless of high or low threshold settings. Figure shows events generated when the data value changes. Each arrow in the figure indicates a generated event.

Figure 7 Changed threshold

Use Changed event triggers with discretion. They are most useful when a change in value is expected to be rare. Monitoring a fabric element that is subject to frequent change generates so many events that it can render it virtually useless. For example, this trigger type is appropriate for FRU failures. It is not appropriate for temperature monitoring.

In-Between triggers

Fabric Watch event triggers are usually set to notify the user of a warning or failure condition, but there is an exception. You can define the In-Between trigger to receive a notification of fault recovery. For example, when measuring port performance, crossing the high threshold triggers an Above threshold event, which displays a warning message. The threshold might be crossed for a period so brief that is not a true cause for an alarm. An In-Between trigger indicates that the port performance has returned to the acceptable range.

Use the In-Between trigger to:

• Verify a successful recovery from a faulty condition.

• Reset the counter value for the next event.

• Identify an element that is consistently operating under marginal condition.

Figure illustrates event notification using an In-Between trigger. The arrow marked with one indicates the

point at which event notification occurs.

Figure 8 In-Between trigger

24 Fabric Watch concepts

Port persistence

In the case of port monitoring, there is an additional factor to consider. The data collected in port monitoring can vary a lot over short time periods. Therefore, the port can become a source of frequent event messages (the data can exceed the threshold range and return to a value within the threshold range).

Fabric Watch uses port persistence for a port event that requires the transition of the port into a marginal status. Fabric Watch does not record any event until the event persists for a length of time equal to the port persistence time. If the port returns to normal boundaries before the port persistence time elapses, Fabric Watch does not record any event.

The port persistence time is measured in seconds, and can be configured. Configuring the port persistence time to zero disables this feature.

Notification methods

There are five notification methods available through Fabric Watch, but not all notification methods can be applied to all of the classes. Valid notification methods are represented through the valid alarm matrix.

Fabric Watch provides the following notification methods:

• ”Switch event (error) log entry” on page 25

• ”SNMP trap” on page 25

• ”RAPITrap” on page 26

• ”Port log lock” on page 26

• ”Email alert” on page 26

To enable event settings, you must set the associated attribute to a nonzero value between one and thirty one. The exact value you specify determines which event notification method Fabric Watch uses if the event setting criteria is met.

For details about valid notification methods in the alarm matrix, see ”Assigning notification methods” on page 26.

Switch event (error) log entry

The switch event (error) log holds up to 1024 entries. This error log stores event information but does not actively send alerts. Use the ErrShow command to view the log.

Log entries can also trigger SNMP traps if the SNMP agent is configured. When the SNMP agent is configured to a specific error message level, then error messages at that level triggers SNMP traps. For information on configuring the SNMP agent using the agtCfgSet command, see the

Fabric OS 5.x command reference guide

SNMP trap

The Simple Network Management Protocol (SNMP) performs an operation called a management station (a workstation that runs network management applications using SNMP protocol) when events occur.

You must configure the software to receive trap information from the network device. You must also configure the SNMP agent on the switch to send the trap to the management station using the agtCfgSet command. For more information on this command, refer to the

reference guide.

An SNMP trap forwards the following information to an SNMP management station:

.

HP StorageWorks Fabric OS 5.x command

• Name of the element whose counter registered an event

• Class, area, and index number of the threshold that the counter crossed

• Event type

• Value of the counter that exceeded the threshold

• State of the element that triggered the alarm

• Source of the trap

Fabric OS 5.x Fabric Watch administrator guide 25

The trap stores event information but does not actively send alerts. Port changes do not generate SNMP traps.

RAPITrap

RAPITrap is a Fabric Watch alarm that actively alerts you to events. After you enable RAPITrap, Fabric Watch forwards all event information to a designated proxy switch. The host API automatically configures the proxy switch, based on firmware version. The switch forwards the information to a server and alerts the SAN manager to event activity.

Third-party applications that use the Brocade API determine the manner that RAPITrap presents alarms to the user.

Port log lock

The port log locks to retain detailed information about an event preventing the information from being overwritten as the log becomes full. This alarm stores event information but does not actively send alerts, which is done automatically when some thresholds are exceeded and an alert is triggered.

NOTE: tFor more information about locking, unlocking, and clearing the port log, refer to the

StorageWorks Fabric OS 5.x command reference guide

Email alert

Email alert sends information about a switch event to a specified email address. Email alert can send information about any error from any element, area, and class.

The email specifies the threshold and describes the event, much like an error message. Use the fwMailCfg command to configure email alerts.

NOTE: To send email alerts, the switch must be connected to a DNS server.

Assigning notification methods

Specify the particular notification method that you want Fabric Watch to use by assigning it a value.

Table 11 shows the numerical values for each notification method.

Table 11 Numerical values of notification methods

Notification method Assigned value

Error Log Entry 1 SNMP Trap 2

HP

.

RapiTrap 4 Port Log Lock 8 E-mail Notification 16

To determine the value for the event setting attribute that enables all desired notification methods, add the values assigned to each method. For example, to enable SNMP trap, RapiTrap and email notification, use the value 22, which is equal to the sum of 2, 4, and 16.

Not all notification methods are valid for all areas. Every area has an associated valid alarm matrix, which is the sum of all valid notification methods for that area. For example, an area with a valid alarm matrix of 25 allows the error log entry (1), port log lock (8) and e-mail notification (16) methods, but does not allow the SNMP trap (2) or RapiTrap (4) methods.

An area with a valid alarm matrix of 31 allows all of the notification types.

26 Fabric Watch concepts

Switch policies

Switch policies are a series of rules that define specific states for the overall switch. Fabric OS interacts with Fabric Watch using these policies. Each rule defines the number of types of errors that transitions the overall switch state into a state that is not healthy. For example, you can specify a switch policy so that if a switch has two port failures, it is considered to be in a marginal state; if it has four failures, it is in a down state.

You can define these rules for a number of classes and field replaceable units, including ports, power supplies, flash memory and fans.

NOTE: See Chapter 5, to view the current switch policies using the switch policy report.

4Configuring Fabric Watch

This chapter describes the procedures used to configure Fabric Watch and contains the following sections:

• Configuring Fabric Watch thresholds, page 33

• Configuring notifications, page 46

• Configuring switch status policy, page 49

• Configuring FRUs, page 51

• Configuring Fabric Watch using Web Tools, page 51

• Configuring Fabric Watch using SNMP, page 52

Configuring Fabric Watch thresholds

After it is activated, Fabric Watch starts using a set of default factory settings that might vary from system to system, depending on the software version and the switch hardware. You can create custom threshold configurations to suit to your unique environment.

Both the factory default and user-customized Fabric Watch settings are individually maintained. You cannot change the default values. During Fabric Watch configuration, you can select whether Fabric Watch should use the default or custom settings for monitoring.

Configuring Fabric Watch thresholds enables you to define your own unique event conditions (such as threshold traits, alarms, and email configuration). For example, it is unlikely that you would need to change the default values for Environment class because the hardware has been tested so extensively. However, if you anticipate a need for additional notifications, or you need to better gauge performance because of noticeable congestion on certain ports, you might want to configure the values for some thresholds.

The steps to configure Fabric Watch Thresholds include:

Step 1: Select the class and area to configure, page 33 Step 2: Configure thresholds, page 35 Step 3: Configure alarms, page 41 Step 4: Disable and enable thresholds by port (optional), page 45

Step 1: Select the class and area to configure

During your planning activities, you should determine exactly what elements or monitors you want to configure, and in which class they reside. After you have made this decision, you need to identify the classes.

To navigate to a specific class and area, use the fwConfigure command from a telnet prompt:

1. Log in to the switch as the administrator.

2. Enter fwConfigure at the command prompt.

3. The fwConfigure menu appears.

swd77:admin> fwconfigure

1 : Environment class 2 : SFP class 3 : Port class 4 : Fabric class 5 : E-Port class 6 : F/FL Port (Optical) class 7 : Alpa Performance Monitor class 8 : EE Performance Monitor class 9 : Filter Performance Monitor class 10 : Security class 11 : Resource class 12 : Quit Select a class => : (1..12) [12] 5

Fabric OS 5.x Fabric Watch administrator guide 33

The fwConfigure menu contains 12 menu items. The first 11 items correspond to the classes available for configuration. Item 12, which is the default, exits the fwConfigure application.

4. From the list displayed, enter the number corresponding to the class that you want to configure. For

example, if you enter 5, the menu corresponding to the E-Port class appears.

1 : Link loss 2 : Sync loss 3 : Signal loss 4 : Protocol error 5 : Invalid words 6 : Invalid CRCS 7 : RXPerformance 8 : TXPerformance 9 : State Changes 10 : return to previous page Select an area => : (1..10) [10] 7

For each class that you select, Fabric Watch provides a list of the areas of the class available for configuration. The final item in the list, which is always the default, returns you to the previous selection screen.

5. Enter the number corresponding to the area that you want to configure, such as 7 for RXPerformance.

Fabric Watch displays a list of monitored elements in this area:

Step 2: Configure thresholds

After you’ve identified and selected the appropriate class and areas, you can configure thresholds for those classes and areas. If you want a basic configuration, accept the default configuration settings. Unless you want to accept the basic (default) configuration, or first disable, enable, or refresh all existing thresholds, proceed to option 4, advanced configuration.

NOTE: For example, you might have ten E-Ports to monitor, but you want to monitor only 8 of them

because the remaining 2 are experiencing performance problems. If you disable monitoring for an element, Fabric Watch does not display this information for it.

The RXPerformance area menu displays the following five options, described in the following sections:

1 : refresh 2 : disable a threshold 3 : enable a threshold 4 : advanced configuration 5 : return to previous page

1. refresh

The refresh option redraws the screen with the most recently updated monitoring information. After the screen refreshes, the same five options appear.

2. disable a threshold

To stop monitoring a selected option, use the disable a threshold option, as follows:

1. Enter 2 at the command prompt.

The system generates similar output to the following:

1 : refresh 2 : disable a threshold 3 : enable a threshold 4 : advanced configuration 5 : return to previous page Select choice => : (1..5) [5] 2

2. Enter the index number of the element for which Fabric Watch should disable monitoring.

40 Configuring Fabric Watch

Step 3: Configure alarms

Alarms act as a signal or alert that notifies you when a threshold has been crossed. You can configure the following types of notification settings for Fabric Watch:

• Triggered

A triggered behavior type signals you once, after a threshold has been crossed. Triggered is the default behavior type signal for all class areas.

• Continuous

A continuous behavior type signals you continuously after a threshold has been crossed.

To set an alarm, choose the type of event about which you want to receive notifications:

• Changed

Triggers an alarm every time the value of what you are monitoring is changed.

• Below

Triggers an alarm every time the value of what you are monitoring goes below the low boundary.

• Above

Triggers an alarm every time the value of what you are monitoring goes above the high boundary.

• In-Between

Triggers an alarm every time the value of what you are monitoring goes in between your low and high threshold boundary.

How to calculate values for alarms

The following sections show how to change the above alarm for the RXPerformance class. Here, a value of 19 is specified. The value is the sum of the alarm matrix values: in this case EmailAlert-16, SnmpTrap-2, and Errlog-1 (16+2+1=19).

To calculate the values to specify in your alarms:

1. Add the numbers beside each state (for the states you want to include). The values for the states are:

•Errlog - 1

•SnmpTrap - 2

• PortLogLock - 4

•RapiTrap - 8

• EmailAlert -16

Watch displays an error message. Ensure that all changes to the threshold and event setting areas of the screen are confirmed before leaving advanced configuration, or the changes are lost.

Step 4: Disable and enable thresholds by port (optional)

On certain occasions, you might want to disable all port thresholds at once. For example, during an event such as an upgrade of a device or server, you might elect not to receive error messages for particular ports. When the upgrade is complete, you can show and enable disabled port thresholds.

To disable all the thresholds for a port, at the command prompt enter:

swd77:admin> fwConfigure --disable --port 9

When you are ready to enable the disabled port thresholds, you can first view all previously disabled ports using the following command:

swd77:admin> fwshow --disable --port

Port Threshold Status ========================= 9 disabled

Fabric OS 5.x Fabric Watch administrator guide 45

A port is not considered disabled if one of the port thresholds is still enabled. To enable all the thresholds for a port, at the command prompt enter:

swd77:admin> fwconfigure --enable --port 9

Configuring notifications

You can be notified of an alarm condition through a notification. The tasks for configuring notifications using Fabric Watch are:

• ”Configuring alarm notifications” on page 46

• ”Configuring SNMP notifications” on page 46

• ”Configuring port log lock actions” on page 47

• ”Configuring email notifications” on page 47

Configuring alarm notifications

When you use alarm notifications, error messages are sent to designated locations such as an error log, SNMP trap view, or email. With an error log, you can log in to a particular switch to view the error messages that have been captured for that particular switch. You can parse the log file to make error message searches quicker and easier.

To ensure that notifications appear in the error log, use the following command:

swd77:admin> fwAlarmsFilterSet 1

The option 1 turns on the alarm notification. If you decide not to have notifications sent, use the following command:

swd77:admin> fwAlarmsFilterSet 0

The option 0 turns the alarm notification off. All alarms are suppressed when alarm notifications are turned off, except for the Environment class and

Resource class. To verify or view your current alarm notifications, use the fwAlarmsFilterShow command.

swd77:admin> fwalarmsfiltershow FW: Alarms are enabled

Configuring SNMP notifications

In environments in which you have a high number of messages (for example, hundreds per day) coming from a variety of switches, you might want to receive them in a single location and view them using a graphical user interface (GUI). In this type of scenario, SNMP notifications might be the most efficient notification method. You can avoid having to log on to each switch individually as you would have to do for error log notifications.

SNMP notifications are configured using snmpMibCapSet, and within Fabric Watch, using alarms. See ”Step 3: Configure alarms” on page 41for details about setting alarms. For details about SNMP configuration, including traps, see the agtCfgSet cand snmpConFig

commands in the

HP StorageWorks Fabric OS 5.x command reference guide

Configuring port log lock actions

Port Log Lock freezes in time the port log dump output if an event is triggered. See ”Step 3: Configure

alarms” on page 41 for details about configuring port log lock actions.

See ”Fabric watch components” on page 19 for more details about port log lock.

.

Configuring email notifications

In environments where it is critical that you are notified about errors quickly, you might want to use email notifications. With email notifications, you can be notified of serious errors via email or a pager, so you can react quickly.

To configure email notifications in a telnet session, enter the fwMailcfg command at the prompt. The fwMailcfg menu, shown in Figure , appears.

Configuring switch status policy

The tasks for configuring a switch status policy are:

• ”Step 1: Plan and define your switch status policy” on page 49

• ”Step 2: Implement your switch status policy” on page 50

• ”Step 3: View your switch status policy” on page 50

Your switch status policy monitors the overall status of a switch based on several contributing parameters. The policy parameter values determine how many failed or faulty units of each contributor are allowed before triggering a status change in the switch from Healthy to Marginal or Down. While some users find that the default settings suit their needs, others need to configure a switch status policy due to unpredictable power outages, temperature changes, or redundancy requirements, among other conditions.

You can configure your switch status policy to define the health of your switch. Generally speaking, Fabric Watch defines the health of your switch using the following terms:

• Healthy

Every contributor is working and therefore healthy.

• Marginal

One or more components are triggering a Warning alarm.

• Down

One or more contributors have failed.

Status events are integrated into Advanced Web Tools and the Fabric Manager option so that if the overall status of your switch is Healthy, the switch color is green. If the overall switch status is Marginal, then the switch color is yellow. Finally, if the overall switch status is Down, the switch color is red. The overall status is calculated based on the most severe status of all contributors.

See the configuring status events using Web Tools.

HP StorageWorks Fabric OS 5.x advanced web tools administrator guide

Step 1: Plan and define your switch status policy

Before entering the switchStatusPolicySet command, plan your switch status policy. How many fans must fail before you consider a switch Marginal? Look at the needs of your system along with the factors that affect its monitors. Table 16 lists the monitors in a switch and identifies the factors that affect their health. Note that not all switches use the monitors listed in Table 16.

Table 16 Switch status policy monitor health factors

for more details about

Monitor Health factors

Power Supplies Power supply thresholds, absent or failed power supply.

Temperatures Temperature thresholds, faulty temperature sensors.

For the SAN Director 2/128, can also occur when Power Supplies are not in the correct slot for redundancy.

Fabric OS 5.x Fabric Watch administrator guide 49

Monitor Health factors

Fans Fan thresholds, faulty fans. WWN Faulty WWN card (applies to modular switches). CP Switch does not have a redundant CP (applies to modular

switches). Blade Faulty blades (applies to modular switches). Flash Flash thresholds. Marginal Ports Port, E-Port, optical port, and copper port thresholds.

Whenever these thresholds are persistently high, the port is

Marginal. Faulty Ports Hardware-related port faults. Missing SFPs Ports that are missing SFP media.

Step 2: Implement your switch status policy

After planning and defining your switch status policy, enter the switchStatusPolicySet command to configure each policy. Each policy has two parameters that can be configured: Marginal and Down. Set the number of units Marginal or Down based on your system requirements for each policy/parameter. The following example shows a switch status policy for Temperature:

Bad Temperatures contributing to DOWN status: (0..10) [0] 3 Bad Temperatures contributing to MARGINAL status: (0..10) [0] 1

The following example shows a switch status policy for Fans:

Bad Fans contributing to DOWN status: (0..3) [0] 2 Bad Fans contributing to MARGINAL status: (0..3) [0] 1

Switch status policies are saved in a non volatile memory, and therefore are persistent until changed.

Step 3: View your switch status policy

After defining and configuring your switch status policy, you can view them using the switchStatusPolicyShow command. Note that the policy you defined here determines the output in the Switch Status Policy Report.

Configuring FRUs

The configuration of FRUs is an exception to the procedures described thus far in this chapter. FRUs are monitored using state values, as opposed to the quantitative values used to monitor the rest of the fabric. As a result of the qualitative nature of this monitoring, the concept of thresholds does not apply.

To configure FRUs:

1. Establish a telnet connection with a switch.

2. Log in using administrative privileges.

3. Enter the fwFruCfg command at the command prompt.

The fwFruCfg command displays your current FRU configuration, as shown in Figure . The types of FRUs are different for the various platforms. In the prompt that follows your current FRU configuration, you are

50 Configuring Fabric Watch

asked to provide values for each FRU alarm state and alarm action. To accept the default value for each FRU (as shown in Figure ), press Return.

After you have configured a FRU alarm state and alarm action, the values apply to all FRUs of that type. For example, the values specified for a slot FRU will apply to all slots in the enclosure.

swd123:admin> fwfrucfg

The current FRU configuration: Alarm State Alarm Action

Figure 14 fwFruCfg configuration

You can specify triggers for any number of alarm states or alarm actions. The first prompt enables you to select which FRU states trigger events.

To select a group of FRU states:

1. Add the numbers beside each state (for the states you want to include).

2. Enter the total at the prompt

For example, to trigger events using the Absent, Off, and Faulty states, add the assigned values and enter that value at the prompt. In this case, the values are 1, 8, and 16, respectively, and the total is 25.

B Basic Fabric Watch configuration guidelines

A default Fabric Watch configuration is available for the purpose of saving setup time. As you gain familiarity with Advanced Fabric Watch features, they can be tailored to suit the fabric environment. The custom settings available in Fabric Watch provide an advanced user much needed flexibility of redefining boundary thresholds and alarm notification methods. The basic concept of Fabric Watch is to monitor the health of an element by sampling the status, comparing the sample data, and if found outside the threshold limits notify the user of the event using one or more selected methods. Since Fabric Watch monitors a variety of custom thresholds to meet a specific objective. This section discusses some of the changes that one should consider implementing to improve the overall efficiency of Fabric Watch.

Customization is recommended to achieve the following objectives.

When Fabric Watch is improperly configured, a large number of error messages can be sent over a short period of time, making it difficult to find those messages that are actually meaningful. If this happens, there are a few simple ways to improve the configuration.

When a large number of messages are sent that are not of importance, the source of the messages can be identified from the error message. Examining error messages for the source can identify those classes which need to be reconfigured.

classes

and

class elements

• Selecting appropriate message delivery method for critical and non–critical events.

• Selecting appropriate thresholds and alarm levels relevant to each class element.

• Defining the appropriate Time Base event triggering based on the class element traits.

• Eliminating message delivery that has little or no practical value to the SAN administrator.

• Consolidating multiple messages, generated from a single event.

, each element with a unique trait must be evaluated prior to defining

When the messages are not desired or not of importance, consider the following options for reconfiguration.

Recheck the threshold settings. If the current thresholds are not realistic for the class and area, messages may be sent frequently without need. For example, a high threshold for temperature monitoring set to less than room temperature is probably incorrectly configured.

If the event setting is continuous, consider switching to triggered. A continuos event setting will cause error messages to be sent repeatedly as long as the event conditions are met. While each message may be meaningful, a high volume of these messages could cause other important messages to be missed.

Examine the notification settings. If you are not interested in receiving messages under certain conditions, ensure that the notification setting for that event is set to zero. For example, you may not be interested in knowing when the sensed temperature is between your high and low temperature settings, so setting the InBetween notification setting to zero for this area will eliminate messages generated in this situation.

C Using Fabric Watch with configuration files

When you activate Fabric Watch, the software starts, using the default settings described in Chapter 5. You cannot alter these default settings; if the default values do not suit your specific needs, configure Fabric Watch to use more appropriate settings.

When you configure the new settings for Fabric Watch, your switch stores the settings in the configuration file. If you change or add settings directly into the configuration file, those settings become your custom configuration.

This chapter discusses the two methods for configuration file usage:

• ”Configuration files”

• ”Profiles”

Configuration files

You can manually edit the configurations files to ensure that the settings meet your needs. To custom configure Fabric Watch with the configuration file:

1. Type configUpload to upload your configuration file to your host.

2. Use a text editor to edit the Fabric Watch values for the elements you want to change.

3. Type configDownload to download the updated configuration to your switch.

4. Type fwConfigReload to reload the Fabric Watch configuration.

Profiles

!

NOTE: This process is disruptive, as a switch reboot will be required.

HP provides partial configuration files, or most appropriate to your particular SAN needs.

IMPORTANT: Fabric Watch configuration settings or

Software 5.x CD that shipped with your switch.

To configure Fabric Watch with a profile:

1. Upload the configuration file to the host by typing configUpload.

2. Retrieve the Fabric Watch

with your switch. Open your configuration file in a text editor.

3. Copy the contents of the profile and append that information to the [Configuration] section of the

configuration file. The contents of the profile overwrite any duplicate information earlier in the configuration.

4. To download your updated configuration to your switch, enter the configDownload command.
