EVA Device Port Status Test

Ports of type Device facilitate communication between the controller and the physical disk. Using this test, you can keep track of the overall health of and problems experienced by the individual device ports on an array controller.

This test monitors the data traffic to and from the EVA storage array, and reports how well the array is able to handle the traffic.

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 device port on the controller.

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.
EvaPerfLocation	Specify the full path of the directory in which the evaperf.exe has been installed.
ArrayName	Specify the name of the EVA SAN array that has been configured for monitoring.
SSSULocation	This test uses the EVAPerf software component to auto-discover the device ports on an EVA storage array. The EVA Controller to Device Port Status test on the other hand uses the SSSU console to discover device ports. During auto-discovery, the EVAPerf utility reports the WWN names of the device ports. In contrast, the SSSU console reports the friendly names of the same device ports. To ensure that device port references are uniform and consistent across tests, you can optionally configure this test to use the SSSU console (instead of EVAPerf) to perform device port discovery. This way, the names of device ports will be the same for this test and the EVA Controller to Device Port Status test. To enable device port discovery via the SSSU console, configure the full path to the location of the SSSU.exe in the SSSULocation text box. If you prefer not to use SSSU.exe for discovering device ports and would rather use the EVAPerf component instead, then, set this parameter to none.
Username, Password and Confirm Password	To use the SSSU.exe for discovering the friendly names of device ports, specify the user credentials using which the HP EVA array is to be accessed in the Username and Password text boxes. Confirm the password by retyping it in the Confirm Password text box. If you do not wish to use the SSSU.exe, then set these parameters to none.
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 60 seconds.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Port status	Indicates the status of this device port.	Status	The value 1 for this measure indicates that the port is up and the value 0 indicates the port is down.
Signal loss count	Indicates the number of times signal losses have occurred on this port during the last measurement period.	Number	Ideally, this value should be 0.
Frames with invalid words received	Indicates the number of frames possessing invalid words that were received by this port during the last measurement period.	Number	Ideally, this value should be 0.
Synchronization loss count	Indicates the number of times synchronization losses that occurred on this port during the last measurement period.	Number	Ideally, this value should be 0.
Link failures	Indicates the number of times link failures occurred on this port during the last measurement period.	Number	Ideally, this value should be 0.
Frames rcvd with EOF delimiter	Indicates the number of frames received with EOF delimiter during the last measurement period.	Number	Ideally, this value should be 0.
Frames discarded	Indicates the number of frames discarded during the last measurement period.	Number	Ideally, this value should be 0.
Frames rcvd with invalid CRC	Indicates the number of frames received with invalid CRC during the last measurement period.	Number	Ideally, this value should be 0.
Protocol errors	Indicates the number of protocol errors that occurred during the last measurement period.	Number	Ideally, this value should be 0.
