Verifying that the host can write to and read from the LUN

Before using the LUN, you should verify that the host can write data to the LUN and read it back.

Before you begin

The LUN must be initialized and formatted with a file system.

About this task

If the storage cluster node on which the LUN is created can be failed over to its partner node, you should verify reading the data while the node is failed over. This test might not be possible if the storage cluster is in production use.

If any of the tests fail, you should verify that the FC service is running and check the FC paths to the LUN.

  1. On the host, copy one or more files to the LUN.
  2. Copy the files back to a different folder on the original disk.
  3. Compare the copied files to the original.

    You can use the comp command at the Windows command prompt to compare two files.

  4. Optional: Fail over the storage cluster node containing the LUN and verify that you can still access the files on the LUN.
