2. Select the Background Job tab.
This tab displays information for all previous and current Background jobs. The Storage Pool,
Number of Concurrent Jobs, and Compressibility Ratio fields contain the default information
entered in the Configuration tab.
3. If you want the job to stop after a particular time period, enter it in the Test Duration field.
Otherwise, leave the Unlimited box checked to allow the test to run indefinitely.
4. If you want to restrict the maximum amount of data the job will write, enter the amount in GB
in the Max Data to Write field. Otherwise, leave the Unlimited box checked to allow it to write
any amount of data.
5. If you want to choose which nodes will be tested, follow the steps below. Otherwise, all
available nodes are selected by default.
a.
Click the Select Nodes link.
b. Select the nodes you want to test.
c. Click Done.
6. Click Start. The job appears in the status table and will run, reading and writing data
continuously, until the job duration is complete (if you added one) or until you cancel the job.
Click Cancel in the appropriate row to cancel a Background job.
NOTE: During a job, one cartridge per storage pool involved in the job is created to support the
background process. This cartridge can be found under the VLS cartridge list prefixed with
“StorageExerciser_.” You can only start one Background job at a time.
You must have at least 5 GB of free space on your VLS in order to run a Background job. If less
than 5 GB is available, the Background job will fail.
The status table displays:
•
Start Time — the date and time the job began.
•
End Time — the date and time the job ended.
•
Current Iteration — the number of the current iteration of the read/write process.
•
Failed Iterations — the number of iterations that failed due to decompression error or other
error.
•
Data Written — the amount of data in bytes that has been written for all iterations combined.
•
Data Read — the amount of data in bytes that has been read for all iterations combined.
•
Status — the state of the jobs can be In Progress, Cancelling, Cancelled, Complete, or Complete
with Errors.
The Complete with Errors status signifies that one or more read operations failed; this may
mean the job uncovered a disk error. If a disk error has occurred, view the
Log Monitor
Summary .
To delete jobs from the status table, check the jobs in the Select column, and then click Delete
Selected.
Log Monitor Summary
The Log Monitor Summary displays decompression error details. You may sort the table by selecting
a column header. You may delete errors by selecting the rows and then selecting Delete Selected.
When enclosure and/or IP address calculations are pending, select Refresh to refresh the information
in the table. Refresh Array Info updates cached array information on the server. Use this if you
make architectural changes such as adding arrays to the VLS.
