VIO Storage Pools Test

You can create a logical volume storage pool on a Virtual I/O Server using the Hardware Management Console or the mksp and mkbdsp commands.

Logical volume storage pools are volume groups, which are collections of one or more physical volumes. The physical volumes that comprise a logical volume storage pool can be of varying sizes and types.

Since critical data is stored and key administrative operations are performed on the physical volumes, it is imperative that the storage pools have sufficient space to handle the current and anticipated data and operational load. This test monitors how each storage pool utilizes the space allocated to it, and proactively alerts you to potential space crunches.

Target of the test : An IBM pSeries server

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each storage pool configured on the VIO server on the IBM pSeries server being monitored.

Configurable parameters for the test
Parameter	Description
Test period	How often should the test be executed
Host	The IP address of the host for which this test is to be configured.
Port	Indicate the port at which the specified Host listens. By default, this is NULL.
HMC Server IP	This test connects to an HMC server to perform LPAR discovery and to collect host-level and "outside view" metrics from the pSeries server. To enable this communication, first, provide the IP address/host name of the HMC server in the HMC Server IP text box. If the eG manager had automatically discovered the target pSeries server by connecting to an HMC server in the environment, then, the IP address/host name will be automatically displayed in the HMC Server IP text box. and user credentials pertaining to that HMC server However, if the pSeries server being monitored was manually added to the eG Enterprise system (and not auto-discovered via the HMC server), then, you will have to explicitly provide the IP address of the HMC server that manages the target pSeries server in the HMC Server IP text box.
HMC Console Username, HMC Console Password and Confirm Password	This test makes REST API requests to the HMC console to pull the metrics. For this purpose, the test needs to be configured with the credentials of a user who can access the HMC console in the HMC Console Username and HMC Console Password text boxes. Confirm the HMC Console Password by retyping it in the Confirm Password text box.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
Total storage pool size	Indicates the total size of this storage pool.	MB
Allocated storage pool size	Indicates the minimum allocation size of this storage pool.	MB
Used storage pool size	Indicates the amount of space in this pool that is currently being utilized.	MB	Ideally, this value should be low.
Free storage pool size	Indicates the currently available space in this pool.	MB
Used storage pool	Indicates the percentage of space in this pool that is currently in use.	Percent	A very high value or a value close to 100% indicates that the pool is rapidly running out of space. You may want to allocate more space to the pool by say, adding more physical volumes to it.
Free storage pool	Indicates the percentage of space in this pool that is currently free.	Percent	A very low value of this measure or a value close to 100% indicates that the pool is rapidly running out of space. You may want to allocate more space to the pool by say, adding more physical volumes to it.
