Measures reported by EMCPvMeCtlEPtStTest

An Expander Port refers to the connection slot(s) used to connect the storage system or unit to multiple storage systems or units. Since the expander ports play a crucial role in expanding the storage capacity of a storage solution, error-prone ports, disconnected ports, or faulty/degraded ports, can deny remote hosts access to the additional storage capacity that has been made available via these ports. To prevent this, administrators will have to rapidly detect port-related abnormalities and swiftly initiate measures to correct them, so that the expanded ports, and through them the attached storage systems, are always accessible. To capture these abnormalities and instantly bring them to the attention of administrators, use the EMCPvMeCtlEPtStTest. For every expanded port in the storage system, this test reports the current status and overall health of the port, and thus leads administrators to defective ports.

Outputs of the test : One set of results for every expander port of the EMC PowerVault ME Storage System being monitored

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
status Indicates the current status of this expander port.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Error 0
Disconnected 1
Warning 2
Unknown 3
Up 4
Not Present 5


Note:

By default, this measure reports the above-mentioned Measure Values while indicating the operational status of an expander port. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
health Indicates the overall health of this expander port.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Fault 0
Degraded 1
Unknown 2
OK 3
Not applicable 4


Note:

By default, this measure reports the above-mentioned Measure Values while indicating the overall health of this expander port. However, in the graph of this measure, the same will be represented using the corresponding numeric equivalents only.
