EMC Unity SAS Ports Test

This test auto-discovers the SAS ports on the target storage system and for each SAS port, reports the current health. Using this test, administrators may be alerted to SAS ports that failed/degraded and replace those ports well before users complain that the target storage system is inaccessible.

Target of the test : An EMC Unity Storage System

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each SAS port on the target storage system being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the storage system for which this test is to be configured.

UniSphere CLI Path

The eG agent uses the command-line utility, UEMCli.exe, which is part of the UniSphere Management Suite, to communicate with and monitor the storage device. To enable the eG agent to invoke the CLI, configure the full path to the CLI here.

Username and Password

Provide the credentials of a user possessing 'monitor' role to access the storage system in the Username and Password text boxes.

Confirm Password

Confirm the Password by retyping it in the Confirm Password text box.

Timeout

Specify the duration (in seconds) beyond which this test should time out in the Timeout text box. The default is 300 seconds.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite 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

Health state

Indicates the current health of this SAS port.

 

The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure value Numeric Value
Normal 0
Attention 1
Unknown 2
Degraded/Warning 3
Minor failure 4
Major failure 5
Critical failure 6
Non-recoverable error 7

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current health of this SAS port. The graph of this measure however is represented using the numeric equivalents only - 0 to 7.

The detailed diagnosis of this measure lists the SAS port ID, name of the storage processor, connector type and health of the port.
