1 Overview of SNMPThis chapter provides an overview of SNMP including an overview of the agent and managementfunctions:• “SNMP Manager Overview” (page 5)

• “SNMP Agent Overview” (page 6)

• “SNMP Manager Functions” (page 8)Unless otherwise specified, the term storage system in this guide refers to the following disk arrays:

• HP StorageWorks XP24000 Disk Array

• HP StorageWorks XP20000 Disk ArrayThe GUI illustrations in this guide were created using a Windows computer with the Internet Explorerbrowser. Actual windows may differ depending on the operating system and browser used. GUIcontents also vary with licensed program products, storage system models, and firmware versions.

SNMP Manager Overview

SNMP Manager and SNMP Agent InteractionThe following figure shows an SNMP environment.

Figure 1 SNMP Environment

SNMP is an industry-standard protocol for managing and monitoring network devices, includingdisk devices, routers, and hubs. SNMP uses SGMP to manage the TCP/IP gateways.The standardized configuration and database of network management information is called aMIB. A standard MIB is common to all SNMP interfaces. An extension MIB is defined by theparticular managed device or protocol.An SNMP manager monitors the devices, which are referred to as managed nodes. The primarytypes of interaction between the SNMP manager and an SNMP agent are polling and trap.Typically, the SNMP manager polls the SNMP agents on a periodic basis, to determine whetherthe device is operating normally. If an abnormal event occurs, the SNMP Agent can report thecondition without a request from the manager, by using a message called trap.When an SNMP Manager polls the agent, the following dialog takes place:

• An SNMP manager sends a request packet to an SNMP agent, which requests data regardingthe status of managed node.

• The SNMP agent sends a response packet back to the SNMP manager.

SNMP Manager Overview 5

• SNMP uses the TCP/IP UDP. If the SNMP agent does not respond within a specified timeperiod, the SNMP manager re-sends the request packet. That time period is set by the systemadministrator, taking into account the network traffic and operation policy.

• If an SNMP agent again does not respond to the re-sent packet, the SNMP manager assumesthat an error has occurred. Depending on the times set for polling and response, this can takeseveral seconds.

If an SNMP agent detects an abnormal event, it sends a trap to the SNMP manager. However, ifa trap is dropped in transmission, the SNMP manager does not know that it was sent. For thisreason, you should use both polling and traps to determine whether an abnormal event hasoccurred.

Management Information Base (MIB)Each managed device has certain types of information, including the configuration information,the status information for device, and statistical, which is known collectively as a ManagementInformation Base (MIB). Each parameter is called a managed object, and it consists of the parametername, one or more parameter(s), and a group of operations that can be executed with the object.The MIB defines the type of information that can be obtained from a managed device, and thedevice settings that can be controlled from a management system.

SNMP Agent Overview

System ConfigurationThe SNMP agent for the HP storage system is on the SVP, which is the computer within the storagearray that manages the storage system. The storage system has an exclusive LAN for communicationsbetween a disk controller and a service processor, and a separate LAN for SNMP. The configurationof each Network Management Station is determined by the type of SNMP Manager. The followingfigure illustrates the SNMP environment.

Figure 2 SNMP Environment Architecture

The following figure shows an example of SNMP operations by using an SNMP manager.

Figure 3 Example of SNMP Operations

SNMP Agent Functions

SNMP TrapsAn SNMP agent reports a storage system error to a SNMP manager using the trap report function.If an error occurs, an SNMP agent issues an SNMP trap to an SNMP manager to report a failure.Issuing an SNMP trap, an SNMP agent also reports a product number, nickname, reference code,and an identifier of the component.The following table lists the events that trigger an SNMP agent trap.

Table 1 SNMP Trap Triggering Events

DescriptionEvents

All operations in a storage system stopped.Acute failure detected.

Operation in a component where a failure occurredstopped.

Serious failure detected.

Partial failure.Moderate failure detected.

Minor failure.Service failure detected.

An SNMP agent logs the most recent 256 traps, so you can see the trap history of a particulardevice.

SNMP Agent OperationsThe following table lists the types SNMP Agent operations.

Table 2 SNMP Agent Operations

DescriptionOperation

Obtains a specific MIB object value.GET REQUEST is the request from an SNMP manager, andGET RESPONSE is the agent's response to that request.

GET

Continuously finds a MIB object.GETNEXT REQUEST is the request from an SNMP manager,and GETNEXT RESPONSE is the agent's response to thatrequest.

GETNEXT

Reports an event (failure) to an SNMP manager.TRAP occurs without a request from the SNMP manager.

6 TroubleshootingThis chapter provides troubleshooting information for the HP StorageWorks XP24000/XP20000SNMP Agent Reference Guide:• “Mitigating SNMP Errors” (page 41)

• “Calling HP Technical Support” (page 41)

Mitigating SNMP ErrorsUse setup.exe when you install a secondary SVP. If you do not, traps could be reported to an IPaddress that is not specified in SNMP settings. This could have serious consequences, includingthe following:

• SNMP Security FunctionIf the SNMP security function is working, and a command is executed from an IP address thatis not entered, you will get a no reply return and a certification error is received for a trap.

• SNMP Cold Trap FunctionDepending on your network environment, when the SVP is rebooted you might not receiveMicrosoft agent SNMP agent cold traps.

◦

◦ The Microsoft SNMP agent might report Link up/Link down Trap when the SVP reboots.

◦ A number of Link up/Link down Traps may be reported when the OS of the SVP isWindows Vista.

• Abnormal Response to SNMP CommandIf an error occurs in the SVP, traps might not be sent.

• Problems Inputting MIB Definition FilesIf you cannot input two or more MIB definition files because of the specifications of the SNMPmanager software, use the MIB definition files for storage system. Error reports include storagesystem nicknames, which can be used to identify each storage system series (for example, HPStorageWorks XP24000/XP20000 Disk Array and HP StorageWorks XP12000/XP10000Disk Array).

Calling HP Technical SupportIf you need to call HP technical support, make sure to provide as much information about theproblem as possible. Include the circumstances surrounding the error or failure, the storage systemRemote Web Console configuration information saved in the floppy diskette(s) by the FD DumpTool, the exact content of any messages displayed on the Remote Web Console, and the severitylevels and reference codes of service information messages (SIMs) displayed on the Status tab ofthe Remote Web Console main window.For worldwide technical support information, see the HP support website:

Conventions for Storage Capacity ValuesHP XP storage systems use the following values to calculate physical storage capacity values (harddisk drives):

• 1 KB (kilobyte) = 1,000 bytes

• 1 MB (megabyte) = 1,0002 bytes

• 1 GB (gigabyte) = 1,0003 bytes

• 1 TB (terabyte) = 1,0004 bytes

• 1 PB (petabyte) = 1,0005 bytesHP XP storage systems use the following values to calculate logical storage capacity values (logicaldevices):

• 1 KB (kilobyte) = 1,024 bytes

• 1 MB (megabyte) = 1,0242 bytes

• 1 GB (gigabyte) = 1,0243 bytes

• 1 TB (terabyte) = 1,0244 bytes

• 1 PB (petabyte) = 1,0245 bytes

• 1 block = 512 bytes
