Selecting an Operating Location

The Switch should be located in a secure or limited-access place to control use of the Switch front panel controls, and to ensure that cable connections are not compromised. The operating location you select for the Switch must meet cooling air requirements and power requirements.

Cooling Air Requirements

Cooling air is drawn into the Switch chassis by the power supply fan and by two other fans mounted on the rear of the chassis; the air is expelled through vents in the front of the chassis. The combined air flow through the Switch is 75 cubic feet per minute (cfpm), and nominal bulk flow of 15 cfpm.

CAUTION:

access to ambient air for cooling.

Do not bloc k the front or rear air vents. The Switch must have free

Installing the Switch 2-3

Power Requirements

You connect the ac power cord to a switched connector on the bottom right side of the Switch front panel. The ac power source must meet thes e requirements:

■

A properly–wired, earth–grounded ac outlet

■

Voltage capability of 90–134 Vac or 180–257 Vac, and IEC 801-5 surge voltage

■

Input voltage frequency of 50–60 Hz

■

Power capability of 219 watts, maximum.

The Switch has an autoranging power supply that automatically accepts voltages within its range. There is no provision for surge protection built into the Switch power supply so the ac source should include provisions to assure cl ean ac pow er.

Selecting a Switch Mounting Method

The Switch can be placed on a table top or other surface, or it can be mounted in an equipment rack.

Placing the Switch on a Surface (Table-top Mounting)

You can set the Switch on a surface, such as a table top, and operate it from that location. Although adhesive rubber feet are included in the Installation Kit, they are not necessary for proper or safe operation of the Switch. If you want to install the rubber feet, perform these steps:

■

Use the alcohol wipes to clean the depression in each corner of the bottom of the chassis; allow the alcohol to dry.

■

Remove the rubber feet from the sheet and insert one in each depression.

■

Press the rubber feet in place firmly.

For table-top mounting continue the installation procedure with Installing the GBIC Modules.

NOTE: If you attach rubber feet, you have to remove them before you can install the Switch in a 19-inch equi pme nt rac k .

Mounting the Switch in an Equipment Rack

You can install the Switch in a RETMA 41U or 42U rack, in a Compaq rack, or in a metric SW600 rack. Observe the following guidelines:

■

When you install the Switch in a closed or multi–rack assembly, be sure the air temperature measured at the Switch front panel does not exceed 40° C (104° F).

■

Make sure the air flow to the Switch is at least 300 cfpm.

■

Verify that when the Switch is installed it does not unbalance the rack or exceed the rack mechanical limits, both with the slide brackets secured and with the slide brackets fully extended.

■

Verify that the supply circuit, the line fuse, and the wire size are appropriate for the service.

Installing the Switch 2-5

■

Verify that all the other equipment installed in the rack has a reliable ground connection; do not rely on connection to a branch circuit, such as a power strip.

■

Route and support the power cord to ensure that the Switch moves freely on the slide brackets without crimping or chafing the power cord, or interfering with other equipment and cables installed in the rack.

Before you install the Switch in the rack you must attach mounting brackets to the rack rails. Where you attach the mounting brackets vertically in the rack depends on your installation, i.e., what other equipment is mounted in the rack along with the Switch. The only tool you need is a Number 2 Phillips screwdriver. Perform the applicable procedure from the following subsections.

Attaching Mounting Brackets in a RETMA 41U Rac k

You mount the Switch in this rack from the front of the rack only. Perform the following steps:

1. Position the mounting template against the front and rear vertical rails

(Figure 2–2), first on one side of the cabinet and then on the other side; make sure the template is parallel from front–to–rear.

Fabric Management through a Single Ethernet Port

Multiple Compaq Storage Switches can be managed through a single IP connectio n to one of the Switc hes usin g Tel net se rvi ces , Web Tool s or SNMP commands, shown in Figure 3-2. Each Switch supports a 10bT ethernet connection that has generally been the link for IP services. There is a second IP connection, the Fibre Channel IP or in-band support which is also available for use when managing a Switch.

Ethernet

Switch 1

Management Station

Switch 2

FC IP

Switch 3

Figure 3-2. Single-port Management of Switches

At this point there are no Host Bus Adapters (HBAs) that can initiate in-band fibre channel IP connections. For that reason, it is necessary to have at least one ethernet connection into the Fabric. From that one entry point, it is possible to manage the remaining Switches in the Fabric using in-band IP services.

The management workstation, which runs a browser, a Telnet session or SNMP, will need to be able to addre ss t he Switc h th at has an ethern et connection. This means that the management workstation and the ethernet IP address of the a Switch need to be in the same subnet. In a ddition, the management station must either have a static ro ute to the FC IP sub net, or the Switch must be the default ga teway for the management workstation. This will allow the management station to direct IP to or through the Switch.

Managing the Switch 3-5

The Switches not connected to the ethernet must have their default gateways set to the Fibre Channel IP address of the Switch connected to the ethernet. Also, these Switches must have their FC IP addresses in a different subnet from the ethernet IP addresses of the management station. Lastly, the FC IP addresses of all Switches must be in the same subnet. Example settings follow:

Management Station

Ethernet IP Address

FC IP Address 192.168.65.09 192.168.65.10 192.168.65.11 192.168.65.12 Default

Gateway

192.168.1.09 192.168.1.10 204.1.1.11 204.1.1.12

192.168.65.10 (any) 192.168.65.10 192.168.65.10

Switch 1Switch 2Switch 3

The effect of this special connectivity is that the route to all switches will be through the single Switch with the ethernet connection. The route back to the workstation from the other Switches will also be though that initial Switch. The initial Switch , which has bo th ethern et and FC IP capability, will act as a “bridge” in that it will route between ethernet and FC IP to send the traffic to the right place with the right protocol.

The domain number uniquely identifies the Switch in a Fabric. This Switch ID is normally automatically assigned by the Switch and may be any value between 0 and 31. You may also assign the initial domain number manually.

The Switch with the lowest initial domain will become the master Switch and control the configuration.

Pressing <Enter>, while BB_credit is selected, displays:

BB_credit 16

The number represents the number of buffers, from 1 to 16, available to the host. The default for G_Port cards is 16. The BB_credit for FL_Port cards is 0. For a complete description of buffer-to-buffer credit, refer to the industry specification Fibre Channel Physical and Signalling Interface (FC-PH).

Resource Allocation Time Out Value (R_A_TOV) is adjustable in 1-second increments using front panel controls, but its value is displayed in milliseconds. This variable works with the variable E_D_TOV to determine the Switch’s actions when presented with an error condition. Allocated circuit resources with detected errors are not released until the time value has expired. If the condition is resolved prior to the timing out, the internal time out clock resets and waits for the next error condition. The range is 1 to 120 seconds.

The operating modes are determined by the host adapter. The five operating modes for the Switch are described in Table 3-4.

Table 3-4

Operating Mode Definitions

Mode Description

0 Normal operating mode, none of the following modes are in effect

Managing the Switch 3-15

2 Isolated operating mode. Set this mode only if the switch’s E_Port discovery process

4 No_Probe operating mode. Set this mode only if the switch’s N_Port discovery process

Tachyon operating mode. Set this mode when there is one or more Tachyon host adapters connected to the Fabric, and a protocol other than SCSI-FCP is being used over this host adapter. When this mode is set, multiple Sequences from different sources will be interleaved to Tachyon at Seque nce boundar ies rather than at fram e boundari es, resulting in better performance from Tachyon.

(transmission of a Class F frame) causes some attached device to fail. When this mode is set, switches will not join to become a Fabric.

(PLOGI, PRLI, INQUIRY) causes some attached device to fail. When this mode is set, devices that do not register themselves with the Name Server will not be present in the Name Server data ba se.

No_MCast operating mode. Set this mode on ly if buffer-to-buffer credit values greater than 16 are needed, and broadcast and multic ast are not needed. When this mode is set, the normal range of buffer-to-buffer credit is change d from 1-16 t o 1-62 and broadcast and multicast are disabled.

NOTE: These modes are additive, for example to set a Switch in Tachyon mode and in No_MCast mode, the operating mode should be set to 9. Any combination of bit maps can be set up to 16, all values above 16 are ignored.

Virtual Channels

The Switch provides the ability to tune the Switch in a specific application. The first two virtual channels are reserved for the Switch’s internal functions

and are not available.

NOTE: The default virtual ch annel se t tings are already optimized for Switch performance. Changing the default values, if properly selecte d, may improve Switch pe rform ance somewhat, but may also severely degrade performance. You should not change these settings without fu lly understanding the chan ge’s effects.

The Virtual Channel Link Con tr ol changes the link con trol channel. The re are two options: 0 and 1.

Option 0 forces data receipt acknowledgments on Class 2 channels to be sent back on the data channel. This traffic consumes a portion of the available data channel bandwidth.

Option 1 allows data receipt acknowledgment packets to use the VC-1 (internal Switch traffic channel) which frees additional bandwidth in the data channel, and transfers the data receipt traffic load to the Switch’s internal traffic channel.

The number is used in an ACC to an NL_Port's FLOGI. If this number is 0, an NL_Port must wait for an R_RDY before it can send a frame to the FL_Port in a loop. If this number is 1, an NL_Port can immediately send a frame to the FL_Port without waiting for an R_RDY. Thus reducing the loop turn around time and increases performance. For a complete description of buffer-to-buffer credit, refer to the industry specification Fib r e Channe l Physical and Signalling Interface (FC-PH).

Managi ng wi th SN MP

The resident SNMP agent allows rem ote Swi tch management via IP over Ethernet and Fibre Channel interfaces and provi des ac cess to most of the functions described in the front panel Menu section.

This section provides an overview of key concepts about Switch management based on Simple Network Manageme n t Protocol (SNMP). Additionally, refe r to other reference s and text books on SNMP for more deta iled discussions of the protocol and usage.

Within the SNMP model, a manageable network consists of one or more manager systems (or network management stations), and a collection of agent systems (or network elements):

■

A manager system runs a management application (such as StorageWorks Command Console GUI) that monitors and controls the network elements

passwd

. Each username (admin, user, other) is

■

An agent system is a network device such as a Fibre Channel Switch, a managed hub, or a bridge, that has an agent responsible for carrying out operations requested by the manager. Therefore, an agent is the interface to a managed device.

The manager communicates with an agent using the Simple Network Management Protocol (SNMP). The Switch agent supports both SNMP version 1 (SNMPv1) and Community-based SNMP version 2 (SNMPv2C).

A manager can retrieve management information, such as its identification, from an agent. There are three operations for this activity:

■

SNMP-GET

■

SNMP-NEXT

■

SNMP-BULKGET (SNMPv2C).

A manager can change management information on the agent. This operation is termed SNMP-SET.

An agent can send information to the manager without being explicitly polled for. This operation is termed a trap in SNMPv1 or a notification in SNMPv2C. Traps or notifications would alert the manager to events that occur on the agent system, such as reboot. For the rest of the document, the term trap is used.

The information on an agent is known as the Management Information Base (MIB). It is an abstraction of configuration and status information. A specific type or class of management information is known as a MIB object or variable. For example, the MIB variable, sysDescr, defines the description of an agent system. The existence of a particular value for a MIB object in the agent system is known as a MIB object instance, or simply instance. Some MIB objects have only a single instance for a given agent system. For exampl e, th e system description and th e in s tance is d en oted as sysDescr.0.

Other MIB objects have multiple instances. For example, the operational status of each Fibre Channel port on a Switch and a particular instance may be denoted as swFCPortOperStatus.5".

MIB obje cts are conceptually organized in a h ierarchical tree s tructure. Each branch in the tree has a unique name and numeric identifier (Figure 3-4). Intermediate branches of the tree serve as a way to group related MIB objects together. The leaves of the tree represent the actual MIB objects. Figure 3-4 illustrates the tree structure, with special attention to the Internet MIB tree and the Fibre Channel MIB tree.

A MIB object is therefore uniquely identified or named by its position in the tree. A full object identifier consists of the identifier of each branch along the path through the tree. For example, the object sysObjectID h as the full identifier of 1.3.6.1.2.1.1.2. For readability the notation { system 1 } may be used.

The Switch’s agent supports the following:

■

SNMPv1 manager

■

Command line utilities to provide access to and command the agent.

■

MIB-II system group, interface group, and SNMP group

■

Fabric Element MIB

■

Vendor-Specific MIBs

■

■

Enterprise Specific traps.

SNMPv1 Transports

The SNMP agent residing on the embedded processor supports UDP/IP over the Ethernet interface or any FC-IP interface. This transport provides an immediate “plug-and-play” support for the Switch, once the IP address has been assigned.

MIB-II Support

There are eleven groups of objec t s speci fie d in MIB-II. The Swi tch ’ s SNMP agent supports 3 of these groups. The three groups supported include:

■

System group (object ID is {iso, org, dod, internet, mgmt, mib-2, 1})

■

Interfaces group (object ID is {iso, org, dod, internet, mgmt, mib-2, 2})

■

SNMP group (object ID is {iso, org, dod, internet, mgmt, mib-2, 11})

The following varia ble s are modif iab le via the SNMP set command, giv e n an appropriate community with read-write access:

The Switch is shipped with the default identifiers.

SysDescr System description: the defa u lt value is se t as “Fibre Channel Switch”

sysObjectID System object identifier vendor’s authoritative identification (1.3.6.1.4.1.1588.2.1.1.1)

sysUpTime The time since the agent was last initialized sysContact The identification and contact information for this system.

By default, this is set as “Field Support”.

sysLocation The node’s physical location. The default setting is “End User Premise”.

The interface group supports three interface drivers: software loopback, Ethernet, and Fibre Channel IP.

Fabric Element MIB Support

There are five object groups defined:

■

Configuration group

■

Operation group

■

Error group

■

Accounting group

■

Capability group.

The agent supports all groups.

Five groups of MIBs are defined and supported:

■

Generic Traps

Setting up the Switch’s SNMP connection to an existing managed network allows the network system administrator to receive the following generic traps:

■

Managing the Switch 3-33

Switch System Group Fabric Group SNMP Agent Configuration Group Fibre Channel Port Group Name Server Group.

coldStart – indicates the agent has reinitialized itself such that the agent’s co n figuration can be altered.

warmStart – indicates the agent has reinitialized itself, but no configuration has changed.

■

linkDown – indicates an IP interface (Ethernet, loop back, or embedded N_Port) has gone down and is not available.

■

linkUp – indicates an IP interface (Ethernet, loop back, or embedded N_Port) h as b ecome av ailable.

NOTE: linkUp and lin kDown traps are not a ssociated with removing or adding a Ethernet cable. This is strictly a driver indication that the inter face is configured, op erational, and available and does not necessarily mean that the physical network c able is connected.

■

authenticationFailure – indicates the agent has received a protocol message that is not properly authenticated. This trap, by default, is disabled but can be enabled via the command agtcfgSet.

Enterprise Specific Traps

Three Enterprise Specific Traps are supported. They are:

■

swFault – indicates the diagnostics detect a fault with the Switch.

■

swSensorScn – indicates an environment sensor changes its operational state. For example; a fan stops working. The VarBind in the Trap Data Unit contains the corresponding instance of the sensor status.

swFCPortScn - a notifica ti o n that a Fib re Channel Port chan ges its operational state. For instance, the Fibre Channel Port goes from on-line to offlin e. The VarB ind in the Trap Data Unit conta in s th e corresponding instance of the port's operational status.

NOTE: S NMP swFCPortScn traps are genera ted on GBIC insertion and remov al even though the state remains offline.

Agent Configuration

NOTE: Changes to SNMP from either Telnet or SNMP are not displayed in SNMP until the Switch is r ebooted run ning. This is due to SNMP running from cache while the active settings are running from the flas h PROM.

The parameters that can be configured include:

■

SNMPv1 communities (up to 6)

■

trap recipients (1 per community)

■

sysName

■

sysContact

■

sysLocation

■

authenticationFailure – indicates the agent has received a protocol message that is not properly authenticated. This trap, by default, is disabled but can be enabled via the command agtcfgSet.

The sysX parameters can be configured via the SNMPv1 SET command w ith an appropriate community. These paramet ers can be conf igure d via a Telnet

connect io n, using the command agtcfgSet.

NOTE: A change in the first two configuration parameters takes effect only after rebooting the Switch.

syslog Daemon

A UNIX style syslog daemon (syslogd) process has been added. Syslogd reads system events and forwards system messages to users and/or writes the events to log files according to your system configuration.

Introduction

Syslogd reads system events and forwards system messages to users and/or stores them in log files according to your system configuration. Events are categorized by facility and severity. Please refer to the manual pages on your UNIX system for a list of facilities and severity levels. The log process is used to log errors and system events on the local machine and are sent to a user or system administrator. The daemon is constantly running and ready to receive messages from system processes . The events are logged ac cordi ng to the statements in the configuration file. In addition, syslogd is enabled to receive messages from a remote machine. Syslogd listens to UDP port 514 for system events. A remote machine does not have to be running UNIX to forward messages to syslogd. But it must follow the basic syslog message format standard.

An example entry in a s yslogd log file is:

Jul 18 12:48:00 sendmail[9558]: NOQUEUE: SYSERR(uucp): /etc/mail/sendmail.cf: line 0: cannot open: No such file or dire ctory

The first two items are the event’s date/time (as known by the machine where syslogd is running) and the machine name that issued the error. This would be the local machine, if the message is generated by a task running on the same machine as syslogd, or a re mo te machin e, if the mess age was received on UDP port 514. The first two items are always present, all other entries are mess age specific.

NOTE: The log file may be located on a differ ent machine and be remotely m ounted. So a local error is an error that occurr ed where syslogd is running, not on the mac hine where the error log physically resides.

syslogd applications for NT and Win95 are available at no charge on several FTP servers on the Internet

syslogd Support

Switch firmware maintains an internal log of all error messages. The log is implemented as a circular buffer, with a storage capability of 30 errors. After 30 errors have been logged, the next error message overwrites the messages at the beginning of the buffer.

Managing the Switch 3-39

If configured, the Switch sends internal error messages to syslogd by sending UDP packet to port 514 on the syslogd machine . Th is allows the storage of Switch errors on a syslogd capable machine and avoids the limitations of the circular buffer.

syslogd provides system error support via a single log file and can notify a system administrator in real time of error events. Additionally, the daemon provides dial home capability.

Error Message Format

Each error message logged sends the following information:

■

Error number (1 for the first error after boot, increments by one with each new error).

■

The error message, exactly as it is stored in the error log (and printed via the command errShow).

The error number makes it easy to identify the error and also determine when a Switch rebooted. If there is a log of error number N from the Switch, followed by another log of error number 0 from the Switch, then the Switch rebooted

between the two errors. The error message includes the Switch that reported the error with the

following event information:

■

ID of the task that generated the error.

■

Name of the task that generated the error.

■

Date and time when the error occurred, as seen by the Switch. This may be different from the first item in the log file, which is the time as seen by the syslogd machi n e . Th ese two time values are differen t if the cloc k s in the Swit ch and in the syslogd machine are not in sync.

■

The error identifier consisting of a module name, a dash and an error name.

■

The error severity.

■

Optional informational part.

■

Optional stack trace.

Message Classification

syslogd messages are classified according to facility and priority (severity code). Thus allowing a system administrator to take different actions depending on the error. The action taken, based on the message’s facility and priority, is defined in the syslog configuration file. Example configurations are provided in a following section.

Managing the Switch 3-41

The Switch uses the facility local7 for all error messages sent to the syslogd.

UNIX provides eight priorities, whereas the Switch provides four severity codes (code LOG_PANIC (0) causes a reboot and is not sent to the syslogd). The mapping between the Switch’s severity codes and UNIX syslogd priorities is provided in Table 3-9.

The Fabric View Pa ge shows the number of network Switches and confirms worldwide names, domain IDs, and Switch names.

Fabric Topology View Page

The Fabric Topology View Page shows the physical configuration including active domains, paths and routing information. For example, the hop count which is the number of Switches that handle a data frame from origination through to the destination.

General Switch View Page

The General Switch View Page displays Switch enclosure information, confirms general Switch informatio n, and includ es GUI but tons for qui ck access to the Administrative Interface, Telnet, and the Performance View.

The front panel identifies the type of interface module installed in each Switch slot, the industry media (GBIC, or Gigabit Interface Converter) used by the ports, and each port’s LED status. From this view, more information is available about the Switch by moving to either the Performance View or the Port Detail View.

Fabric Management and Licensing

All Compaq Switches are license. It is possible that other Switches in a Fabric may not have the Web browser license key installed. This does not prevent a Switch from appearing in the Fabric view page on the browser, but attempting to click on an unlicensed Switch in order to manage that Swi t ch results in a failure. Each Switch must contain a web management license in order for the web browser to display detailed performance data on ports, enter administrative data, and to perform Switch management functions on that Switch using the web. Telnet and SNMP can always be used to manage a Switch without a li cen se.

License Installation

Web management requires a license to operate. Without a License key installed in the Switch, Web browsers are not able to connect to the Switch. The License Key has been installed at the factory for Compaq Switches.

Managing the Switch over the Web 5-5

CAUTION:

thus eliminating any /all valid license keys. The license key is unique to each Switch; therefore, a license for one Switch will not operate on another.

If an invalid key number is e ntered the existing license (if any) is overwritten,

To install the License Key:

1. Log on the Switch via Telnet.

2. On the Telnet command line, type:

licenseShow

3. Verify the current license keys, if the Web key is not installed continue

with the next step.

4. On the Telnet command line, type:

licenseAdd “key”

where, “key” is the license key string of alphanumeric characters in double quotes (“key”) that must be entered exactly as given including case. For example, “RdxS9S9ezSd cdTs ”.

5. Once the license is entered, check for it with the licenseShow command

and if present reboot the Switch.

Port Detail View Page

The Port Detail View Page, Figure 5-6, provides statistics for each port. The page features 16 cascaded folders (tabs) one for each port. Each folder has a tab on the top to show the port number and a status light to tell the port state.

The port information is updated once per second. However, the time interval maybe as long as 2.5 seconds depending on the browser used. By glancing at those 16 or 8 tabs, a system administrator will gain the knowledge of each port state. The default top folder displayed on this page is for the port number checked from the General Switch View Page. Clicking on a tab brings the corresponding port folder to the front.

NOTE:

This page shows an FL_P ort as being offline if you are running cross port connected testing, the reason is that you ca n have only one Principle per Switch. The FL_Port to FL_Port testing still pr oceeds even though this is NOT the correct way to connect FL_Por ts.

Below the folders is a push button linked to the Administrative Interface Page where port enable/ disable can be performed. A push button linked to the Performance View Page where port and Switch throughput data is plotted. A Done push button is used to exit from the pa ge.

Each port folder contains general port status information such as the port number, port type (E-Port, G-Port), port's WWN name and some detailed information, such as t he number of interrupts, number of link failures, number of parity errors, number of time outs and the size of free buffer.

The LED located in the upper right corner in each tab resembles the port LED in the Switch front panel.

Port Detail View Pa ge field are described in Table 5-4.

Performance View Page

The Performance View Page, Figure 5-7, displays port and Switch throughput in bytes per second. Each port is numbered and throughput for the entire Switch is displayed under the individual port readings.

The first 16 graphs show the port throughput for port number 0 through 15. Throughput for the entire Switch is displayed in the long rectangular graph at the bottom.

Horizontal axis represents time elapsed. The port throughput graphs hold up to 60 seconds of performance data. The Switch throughput graph at the bottom holds up to 4 minutes of performance data. Vertical axis in each graph shows throughput (in byte per second). It is automatically scaled depending on the Switch activity. The display is updated roughly once per second.

The total throughput value is the throughput sum for all ports. The throughput number represents the number of bytes received plus the number of bytes transmitted each second. Note that, because the Switch also transmits all data it receives, the total throughput for the Switch could, alternately, be stated as one-half (1/2) of the throughput sum of all ports.
