HP P2000 Expander Status Test
This test reports the current status of the expander present in the HP P2000 SAN storage system and the status of the SES elements available in the expander.
Target of the test : A HP P2000 SAN storage system
Agent deploying the test : A remote agent
Outputs of the test : One set of results for every expander being monitored.
| Parameter | Description |
|---|---|
|
Test period |
How often should the test be executed . |
|
Host |
The host for which the test is to be configured. Since the storage device is managed using the IP address of its storage controller, the same will be displayed as host. In case of a dual-controller configuration, the IP address of the primary controller will be displayed here. |
|
Port |
The port number at which the specified host listens. By default, this is NULL. |
|
Additional Controller IP |
By default, this test always connects to the Host to collect metrics. If the Host is unavailable, then the test will not be able to execute. This is because, the Additional Controller IP is set to none by default. If the monitored storage device has two controllers, then you can configure the test to connect to an alternate controller, if the host is unreachable. For this purpose, specify the IP address of the alternate controller in the Additional Controller IP text box. |
|
User and Password |
In order to monitor a HP P2000 SAN storage system, the eG agent has to be configured with the credentials of a user who has been assigned the Monitor role. Specify the login credentials of such a user in the User and Password text boxes. To know how to create such a user, refer to Pre-requisites for monitoring the HP P2000 SAN storage system. |
|
Confirm Password |
Confirm the password by retyping it here. |
|
ServicePort |
The Management Controller of the HP P2000 storage system provides access for monitoring and management via the HTTP and HTTPS protocols for XML API request/response semantics. To enable the eG agent to access the management controller, invoke the XML API commands, and collect the required metrics, you need to specify the service port on the controller that listens for HTTP/HTTPS requests for XML API semantics. By default, this is port 80. |
|
Timeout |
Specify the time duration for which this test should wait for a response from the storage system in the Timeout text box. By default, this is 60 seconds. |
|
SSL |
By default, HP P2000 SAN system is not SSL-enabled. This is why, this flag is set to False by default. If it is SSL-enabled, then change this flag to True. |
|
Authentication Type |
By default, MD5 is chosen from this list indicating that the eG agent uses MD5 authentication algorithm to monitor the target HP P2000 SAN Storage system. However, if you wish to monitor HP MSA 2060 FC Storage system using the HP P2000 SAN monitoring model offered by eG Enterprise, then, choose SHA256 from this list. This indicates that the eG agent uses SHA256 authentication algorithm to collect metrics from the HP MSA 2060 FC Storage system. |
|
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:

Status |
Indicates the current status of this expander. |

The values that this measure can report and the their corresponding numeric values are tabulated below:
Note: By default, this measure reports the above-mentioned Measure Values while indicating the current status of this expander. However, in the graph of this measure, status will be represented using the corresponding numeric equivalents only. |

Elem status |
Indicates the current status of the SES elements available in this expander. |
MB/Sec |
Most SCSI enclosure products support a protocol called SCSI Enclosure Services (SES). The initiator can communicate with the enclosure using a specialised set of SCSI commands to access power, cooling, and other non-data characteristics. The SCSI initiator communicates with an SES device using two SCSI commands: Send Diagnostic and Receive Diagnostic Results. Some universal SCSI commands such as Inquiry are also used with standalone enclosure services to perform basic functions such as initial discovery of the devices. These commands can be addressed to a specific SES element in the enclosure. There are many different element codes defined to cover a wide range of devices. The most common SES elements are power supply, cooling fan, temperature sensor, and UPS. The values that this measure can report and the their corresponding numeric values are tabulated below:
Note: By default, this measure reports the above-mentioned Measure Values while indicating the current status of the SES elements. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only. The detailed diagnosis of this measure if enabled, lists the PHY type of the SES element and the primary reason for the health of the SES element. |
