EVA Host to LUN Mapping Test

This test auto-discovers the external hosts connecting to the LUNs on the storage array, and reports the operational state of each such host.

Target of the test : An EVA Storage Array

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each external host connecting to a LUN on the EVA storage array that is monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

Port

Refers to the port used by the EVA SAN device.  By default, it is null.

EVASystemIP

Specify the IP address of the HP EVA SAN.

ArrayName

Specify the name of the EVA SAN array that has been configured for monitoring.

SSSULocation

Install the SSSU.exe software and specify the full path to the install directory of this software here.

Username and
Password

Specify the user credentials using which the HP EVA array is to be accessed.

Timeout

Indicate the duration (in seconds) for which this test should wait for a response from the storage device. By default, this is set to 120 seconds.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Indicates the operational mode of this host.

Status

The values that this measure can report and the states they indicate are tabulated below:

State Value
good or attention or normal 1
Failed or bad 0
Unknown or not available or notinstalled or not_present or unsupported, etc. 2

Note:

By default, this measure reports the States listed in the table above to indicate the current operational mode of each host. The graph of this measure however, represents the status of a host using the numeric equivalents only.

The detailed diagnosis of this measure indicates the LUN number and virtual disk name associated with this host.
