3.1.3.3 Identify ME4 Series volume SCSI IDs
The SCSI IDs of ME4 Series volumes can be retrieved using one of the two following ways:
Option 1: Export the volume information in ME Storage Manager.
In ME Storage Manager in the Volumes topic, select the desired volume or volumes and click the Export to
CSV button. Select the data and format in the Export Data to CSV dialog. Once the CSV file is created and
downloaded to your computer, open the file with a word processor or spreadsheet application. The volume
SCSI IDs are listed in the CSV file in the WWN column. See the following figures.
