HP P2000 VDisk Status Test

A Vdisk is a group of disk drives configured with a RAID level. The HP P2000 G3 system can have a maximum of 16 Vdisks per controller in a dual controller system for a total of 32 virtual disks. In a single controller system, the maximum is 32 virtual disks.

If a user to the storage system is unable to access data in the storage system, it could be because a faulty, degraded, critical, or simply, an offline Vdisk is holding the disk drive that contains the data being accessed. To be able to proactively detect such abnormalities and promptly initiate corrective action, administrators need to periodically check the health of each Vdisk in the HP P2000 storage system. This is where the HP P2000 VDisk Status test helps. This test reports the current operational status and the overall health of each Vdisk in the target storage system, so that administrators are instantly intimated of the abnormal state of a Vdisk and are enabled to rapidly initiate remedial action, so that critical data always remains accessible to users.

Target of the test : A HP P2000 SAN storage system

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each Vdisk being monitored

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed .

Host

The host for which the test is to be configured. Since the storage device is managed using the IP address of its storage controller, the same will be displayed as host. In case of a dual-controller configuration, the IP address of the primary controller will be displayed here.

Port

The port number at which the specified host listens. By default, this is NULL.

Additional Controller IP

By default, this test always connects to the Host to collect metrics. If the Host is unavailable, then the test will not be able to execute. This is because, the Additional Controller IP is set to none by default.

If the monitored storage device has two controllers, then you can configure the test to connect to an alternate controller, if the host is unreachable. For this purpose, specify the IP address of the alternate controller in the Additional Controller IP text box.

User and Password

In order to monitor a HP P2000 SAN storage system, the eG agent has to be configured with the credentials of a user who has been assigned the Monitor role. Specify the login credentials of such a user in the User and Password text boxes. To know how to create such a user, refer to Pre-requisites for monitoring the HP P2000 SAN storage system.

Confirm Password

Confirm the password by retyping it here.

ServidePort

The Management Controller of the HP P2000 storage system provides access for monitoring and management via the HTTP and HTTPS protocols for XML API request/response semantics. To enable the eG agent to access the management controller, invoke the XML API commands, and collect the required metrics, you need to specify the service port on the controller that listens for HTTP/HTTPS requests for XML API semantics. By default, this is port 80.

Timeout

Specify the time duration for which this test should wait for a response from the storage system in the Timeout text box. By default, this is 60 seconds.

SSL

By default, HP P2000 SAN system is not SSL-enabled. This is why, this flag is set to False by default. If it is SSL-enabled, then change this flag to True.

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:

  • 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

Status

Indicates the current status of this Vdisk.

 

The values that this measure can report and their corresponding numeric values are tabulated below:

Measure Value Numeric Value
Offline 0
Critical 1
Fault tolerant with down disks 2
Quarantined critical 3
Quarantined offline 4
Quarantined with down disks 5
The vdisk is stopped 6
Unknown 7
Fault tolerant and online 8
The vdisk is online 9

Note:

By default, this measure reports the above-mentioned Measure Values only. However, in the graph of this measure, the Vdisk status will be represented using the corresponding numeric equivalents only.

Health

Indicates the overall health of this vdisk.

 

The values that this measure can report and the states they indicate are tabulated below:

State Numeric Value
Fault 0
Degraded 1
OK 2
Unknown 3

 

Note:

By default, this measure reports the above-mentioned States while indicating the health of this vdisk. However, the graph of this measure will be represented using the corresponding numeric equivalents of the States as mentioned in the table above.

The detailed diagnosis of this measure if enabled, lists the name of the vdisk and the primary reason why the health state of that vdisk is what it is.
