EVA Disk Group Status

This test reports the current operational state of each disk group on the storage array, monitors the space usage of every group, and enables administrators to accurately identify which disk group is experiencing a space crunch currently.

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 physical disk group on the EVA array.

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.

Confirm Password

Confirm the password by retyping it here. 

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.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Disk group operational state

Indicates the current operational mode of this disk group.

Status

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

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 disk group. The graph of this measure however, represents the status of a fan using the numeric equivalents only.

Total storage capacity

Indicates the total storage space on the this group.

GB

 

Used storage capacity

Indicates the amount of storage space on this group that is in use currently.

GB

 

Percent free space

Indicates the percentage of space available for use on the this group.

Percent

Ideally, the value of this measure should be high. A low value or a value that decreases consistently over time could indicate a potential space crunch on the group.

Disk count

Indicates the number of disks in this group.

Number

 

Drive state

Indicates the current state of drives in this group.

Status

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

State Value
Online 1
Offline 0
Unknown 2

Note:

By default, this measure reports the States listed in the table above to indicate the current state of drives. The graph of this measure however, represents the status of the drives using the numeric equivalents only.
