How Can I Identify Host Services Running on the System Subrack?

The following describes how to identify host services running on a system subrack and provides a reference for stopping services before you replace a system subrack.

1. Log in to DeviceManager of the storage system.
2. Determine disk domains involved in the system subrack.
   1. In the navigation tree, click System.
   2. In the left function pane, click the cabinet where the system subrack resides.
   3. Click the system subrack.
   4. In the function pane below, view and record the disk domain where each disk in the subrack resides.

3. Determine file systems and LUNs contained in those disk domains.
   1. In the navigation tree, click Provisioning.
   2. In the Storage Configuration and Optimization area, click Storage Pool.
   3. Select all storage pools that belong to disk domains in Step 2.4. In the function pane below, view and record file systems and LUNs of which Mapping is Mapped.

4. Determine share paths to which these file systems map.
   1. In the navigation tree, click Provisioning.
   2. In the File Storage Service area, click Share.
   3. In the function pane, check whether all file systems in Step 3.3 exist. View and record the share path. Stop the services running on the share path on the host.

5. Determine the hosts to which these LUNs map.
   1. In the navigation tree, click Provisioning.
   2. In the Block Storage Service area, click Host.
   3. Select the hosts of which Added to Host Group is Yes. In the Mapped LUNs tab below, check whether the LUNs that have been recorded exist.
      • If yes, there are services related to the system subrack running on this host. Stop the services running on the LUN of the host.
      • If no, go to Step 3.3 until the services on all recorded LUNs are stopped on the host. Then replace the system subrack.
