XIO DAE Controllers Test
The DAE Controller or Link Control Card module is a horizontal card in the middle of the DAE. There are two LCC modules that support the backend SAS connections to the controllers. This test auto-discovers the DAE Controllers of the target EMC XtremIO and reports whether/not each DAE Controller is enabled. Besides, this test reports the current health, life cycle state of each DAE Controller and the current state of the Serial Attached SCSI ports on each DEA Controller. By closely monitoring the health of the DAE Controllers, abnormalities of the DAE Controllers can be identified and rectified at ease!
Target of the test : An EMC XtremIO Storage array
Agent deploying the test : A remote agent
Outputs of the test : One set of results for each DAE Controller of the target EMC XtremIO being monitored
Parameter | Description |
---|---|
Test Period |
How often should the test be executed. |
Host |
The IP address of the storage device for which this test is to be configured. |
Port |
The port number at which the storage array listens. The default is NULL. |
XtremIO User and XtremIO Password |
Provide the credentials of a user who has read only privileges to access the XtremIO storage array in the XtremIO User and XtremIO Password text boxes. |
Confirm Password |
Confirm the password by retyping it here. |
SSL |
The eG agent collects performance metrics by invoking Restful APIs on the target Storage array. Typically, the Restful APIs can be invoked through the HTTP or the HTTPS mode. By default, the eG agent invokes the Restful APIs using the HTTPS mode. This is why, the SSL flag is set to Yes by default. If the target storage array is not SSL-enabled, then the Restful APIs can be accessed through the HTTP mode only. In this case, set the SSL flag to No. |
XMSIP |
This parameter is applicable only for EMC XtremIO 4.x. By default, None will be chosen from this list. If the target EMC XtremIO storage array is within a XMS Management Server that is auto-discovered, then the IP or host name of that XMS Management Server will be displayed in this list. Select that particular XMS IP to configure this test. If you wish to monitor an EMC XtremIO Storage Array that is either not an integral part of the auto-discovered XMS Management Server or a brand new EMC XtremIO Storage Array, choose the Other option. This will enable you to add a new XMS Managament Server. To know how to add a new XMS Management Server, refer to Adding a new XMS. |
DD Frequency |
Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 2:1. This indicates that, by default, detailed measures will be generated every second time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency. |
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:
