RAID Power Supplies Test

The sudden failure of the power supply units of a storage device can cause the device to crash, leading to critical loss of data. To avoid this, you need to keep an eye on the state of each power supply unit of the storage system. This can be achieved using the RAID Power Supplies test. This test auto-discovers the power supply units of the storage system and reports the overall health and operational state of each unit.

Target of the test : An SMI-S compliant storage device

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each power supply unit on the storage system.

Configurable parameters for the test
Parameter	Description
Test period	How often should the test be executed
Host	The IP address of the storage device.
Port	The port number at which the storage device listens to. By default, this is NULL.
User and Password	Specify the credentials of a user who has the right to execute API commands on the storage device and pull out metrics. The exact role that is to be assigned to such a user will differ from one device to another – for instance, when monitoring 3PAR, you will have to provide the credentials of a user who has been assigned the Monitor role, here.
Confirm Password	Confirm the password by retyping it here.
SSL	Set this flag to Yes, if the storage device being monitored is SSL-enabled.
IsEmbedded	If this flag is set to True, it indicates that the SMI-S provider is embedded on the storage platform. On the other hand, if this flag is set to False, it indicates that the SMI-S provider has been implemented as a proxy.
SerialNumber	If the SMI-S provider has been implemented as a proxy, then such a provider can be configured to manage multiple storage devices. This is why, if the IsEmbedded flag is set to False, you will have to explicitly specify which storage system you want the eG agent to monitor. Since each storage system is uniquely identified by a SerialNumber, specify the same here. The format of this number and where you can find it will differ from one storage system to another. You are hence advised to contact the storage administrator to know what to enter against SerialNumber. For example, the serial number for an EMC CLARiiON device will be of the format, FCNMM094900059.
NameSpace	Specify the namespace that uniquely identifies the profiles specific to the provider in use.

Measurements made by the test

Measurement

Description

Measurement Unit

Interpretation

Health state

Indicates how healthy this power supply unit currently is.

The values that this measure can report and their corresponding numeric values are discussed in the table below:

Numeric Value	Measure Value
0	OK
1	Unknown
2	Degraded/Warning
3	Minor failure
4	Major failure
5	Critical failure
6	Non-recoverable error

Note:

By default, this measure reports the Measure Values discussed above to indicate the state of a power supply unit. The graph of this measure however, represents the state of the power supplies using the numeric equivalents only.

Operational status

Indicates the current operational state of this power supply unit.

The values that this measure can report and their corresponding numeric values are discussed in the table below:

Numeric Value	Measure Value
0	OK
1	In Service
2	Power Mode
3	Completed
4	Starting
5	Dormat
6	Other
7	Unknown
8	Stopping
9	Stressed
10	Stopped
11	Supporting Entity in Error
12	Degraded or Predicted Failure
13	Predictive Failure
14	Lost Communication
15	No Contact
16	Aborted
17	Error
18	Non-Recoverable Error

Note:

By default, this measure reports the Measure Values discussed above to indicate the operational state of a power supply unit. In the graph of this measure however, operational states are represented using the numeric equivalents only.

Detailed operational state

Describes the current operational state of this power supply unit.

This measure will be reported only if the API provides a detailed operational state.

Typically, the detailed state will describe why the power supply unit is in a particular operational state. For instance, if the Operational status measure reports the value Stopping for a power supply unit, then this measure will explain why the power supply is being stopped.

The values that this measure can report and their corresponding numeric values are discussed in the table below:

Numeric Value	Measure Value
0	Online
1	Success
2	Power Saving Mode
3	Write Protected
4	Write Disabled
5	Not Ready
6	Removed
7	Rebooting
8	Offline
9	Failure

Note:

By default, this measure reports the Measure Values discussed above to indicate the detailed operational state of a PSU. In the graph of this measure however, detailed operational states are represented using the numeric equivalents only.
