XIO Slots Test

This test reports the current state of each slot on the target EMC XtremIO. Using this test, erroneous slots can be identified and rectified so that additional disks are inserted into the slots well before administrators are informed about storage space crunch!

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 slot on the target EMC XtremIO Storage array

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


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


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.


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.


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 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

Slot state

Indicates the current state of this slot.


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

Measure value Numeric Value
Resident_ssd 0
Ok 1
Empty 2
Unanticipated_disk 3
Error 4
Unsupported_disk 5
Uninitialized_disk 6


By default, this measure reports the Measure Values listed in the table above to indicate whether/not the Storage Controller is enabled. The graph of this measure however is represented using the numeric equivalents only - 0 to 6.
