EVA LUN Status Test

This test reports the current operational state of each LUN on the EVA storage array, and also the current state of the read, write, and mirror caches.

Target of the test : An EVA Storage Array

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each LUN on the EVA array.

Indicate the duration (in seconds) for which this test should wait for a response from the storage device. By default, this is set to 120 seconds.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

vDisk operational state

Indicates the current operational mode of this LUN.

Status

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

State Value
good or attention or normal 1
Failed or bad 0
Unknown or not available or notinstalled or not_present or unsupported, etc. 2

Note:

By default, this measure reports the States listed in the table above to indicate the current operational status of the LUN. The graph of this measure however, represents the status of a LUN using the numeric equivalents only.

The detailed diagnosis of this measure reports the allocated and requested capacity of each LUN.

vDisk read cache state

Indicates the current state of the read cache.

Status

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

State Value
Enable 1
Disable 0
Unknown 2

Note:

By default, this measure reports the States listed in the table above to indicate the current status of the read cache. The graph of this measure however, represents the status of a read cache using the numeric equivalents only.

vDisk write cache state

Indicates the current state of the write cache.

Status

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

State Value
Writeback, writethrough 1
Failed, disabled 0
Unknown 2

Note:

By default, this measure reports the States listed in the table above to indicate the current status of the write cache. The graph of this measure however, represents the status of the write cache using the numeric equivalents only.

vDisk mirror cache state

Indicates the current state of the mirror cache.

Status

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

State Value
mirrored 1
notmirrored 0
Unknown 2

Note:

By default, this measure reports the States listed in the table above to indicate the current status of the mirror cache. The graph of this measure however, represents the status of the mirror cache using the numeric equivalents only.

vDisk allocated capacity

Indicates the storage capacity allocated to this LUN/vDisk.

Millions of blocks

 

vDisk requested capacity

Indicates the storage capacity requested from this LUN/vDisk.

Millions of blocks
