Hitachi Management Modules Test

The management module provides power control of the modules, status monitoring, system console, and management network functions. One (standard) or two (maximum) management modules can be mounted in the server chassis of the Hitachi Compute Blade. With two management modules installed, the modules provide a redundant configuration. Each module is hot-swappable and supports live firmware updates without the need for shutting down the blades. Each module supports an independent management LAN interface from the data network for remote and secure management of the chassis and all blades. Each module supports a serial CLI and a Web interface. The management modules also support SNMP and email alert notification so that administrators are always notified of any issues. If the management modules fail to function, then the target Hitachi Compute Blade may malfunction resulting in the failure of several hardware and software components interconnected with the blade. To avoid such fatal failures, administrators should constantly maintain a vigil over the management modules. The Hitachi management Modules test helps administrators in this regard!

For each management module in the chassis of the target Hitachi Compute Blade, this test reports the current health and power supply status. In addition, this test also reports the operational status as well as the maintenance mode of each management module. Using this test, administrators can easily figure out abnormalities in the management module and take necessary measures to combat the abnormalities at the earliest!

Target of the test : Hitachi Compute Blade

Agent deploying the test : An external agent

Outputs of the test : One set of results for each management module in the Hitachi Compute Blade being monitored.

Configurable parameters for the tests
  1. TEST PERIOD - How often should the test be executed
  2. Host – The IP address of the Hitachi Compute Blade
  3. SnmpPort – The port at which the Hitachi Compute Blade exposes its SNMP MIB; the default is 161.
  4. SNMPVERSION – By default, the eG agent supports SNMP version 1. Accordingly, the default selection in the snmpversion list is v1. However, if a different SNMP framework is in use in your environment, say SNMP v2 or v3, then select the corresponding option from this list.
  5. SNMPCommunity – The SNMP community name that the test uses to communicate with the firewall. This parameter is specific to SNMP v1 and v2 only. Therefore, if the snmpversion chosen is v3, then this parameter will not appear.
  6. username – This parameter appears only when v3 is selected as the snmpversion. SNMP version 3 (SNMPv3) is an extensible SNMP Framework which supplements the SNMPv2 Framework, by additionally supporting message security, access control, and remote SNMP configuration capabilities. To extract performance statistics from the MIB using the highly secure SNMP v3 protocol, the eG agent has to be configured with the required access privileges – in other words, the eG agent should connect to the MIB using the credentials of a user with access permissions to be MIB. Therefore, specify the name of such a user against the username parameter. 
  7. CONTEXT – This parameter appears only when v3 is selected as the SNMPVERSION. An SNMP context is a collection of management information accessible by an SNMP entity. An item of management information may exist in more than one context and an SNMP entity potentially has access to many contexts. A context is identified by the SNMPEngineID value of the entity hosting the management information (also called a contextEngineID) and a context name that identifies the specific context (also called a contextName). If the USERNAME provided is associated with a context name, then the eG agent will be able to poll the MIB and collect metrics only if it is configured with the context name as well. In such cases therefore, specify the context name of the USERNAME in the CONTEXT text box.  By default, this parameter is set to none.
  8. authpassSpecify the password that corresponds to the above-mentioned username. This parameter once again appears only if the snmpversion selected is v3.
  9. confirm password– Confirm the authpass by retyping it here.
  10. authtype – This parameter too appears only if v3 is selected as the snmpversion. From the authtype list box, choose the authentication algorithm using which SNMP v3 converts the specified username and password into a 32-bit format to ensure security of SNMP transactions. You can choose between the following options:

    • md5 – Message Digest Algorithm
    • sha – Secure Hash Algorithm
  1. encryptflag– This flag appears only when v3 is selected as the snmpversion. By default, the eG agent does not encrypt SNMP requests. Accordingly, the encryptflagis set to no by default. To ensure that SNMP requests sent by the eG agent are encrypted, select the yes option. 
  2. encrypttype– If the encryptflag is set to yes, then you will have to mention the encryption type by selecting an option from the encrypttype list. SNMP v3 supports the following encryption types:

    • des – Data Encryption Standard
    • AES – Advanced Encryption Standard
  3. encryptpassword – Specify the encryption password here.
  4. confirm password – Confirm the encryption password by retyping it here.
  5. TIMEOUT - Specify the duration (in seconds) within which the SNMP query executed by this test should time out in the TIMEOUT text box. The default is 10 seconds.
  6. DATA OVER TCP – By default, in an IT environment, all data transmission occurs over UDP. Some environments however, may be specifically configured to offload a fraction of the data traffic – for instance, certain types of data traffic or traffic pertaining to specific components – to other protocols like TCP, so as to prevent UDP overloads. In such environments, you can instruct the eG agent to conduct the SNMP data traffic related to the monitored target over TCP (and not UDP). For this, set the data over tcp flag to Yes. By default, this flag is set to No.
