Taking a resource offline

Complete this task to take a resource offline for a service action.

Your resource must be online before you can take it offline.
You cannot take a resource offline if it is currently in one of the following states:
  • Quiescing (Going offline)
  • Quiesced (Offline)
  • Resuming (Coming online)
You must wait for the resource to enter a state that allows you to take it offline.
Note: These steps allow you to take a resource offline without a corresponding log entry. You can also take a resource offline from the Log entry details page in the DS Storage Manager.
  1. In the navigation, select Real-time manager > Monitor system > Properties.
  2. Choose the storage complex that contains the resource that you are taking offline.
  3. Choose the storage unit that contains the resource that you are taking offline.
  4. Choose the enclosure that contains the resource that you are taking offline.
  5. Choose the resource that you are taking offline.
  6. Click on the Status tab to view status information for the selected resource.
  7. Select the resource that you want to take offline by clicking on the selection field in the properties table.
  8. Select Take offline from the drop down list above the properties table.
  9. Confirm that you want to take the resource offline. This begins the process that quiesces the resource.
  10. Use the Refresh button to view the status change for your selected resource. The resource has finished the offline process when the resource changes to a Prepared for service state.
You must replace the resource after removal or, if you did not remove the resource, bring the resource online. Leaving a resource offline for any period of time makes your system susceptible to additional fault or error events that could cause loss of operation or data.
