If you are going to create a file system for an HDLM device, specify the name of a logical device file of the HDLM device for the mkfs command. However, if a file system is created for a SCSI device that is already in use, the applicable HDLM device will be created with a file system even without creating a new file system by using the mkfs command.
Furthermore, if the mkfs command is executed for a SCSI device, a message confirming whether to execute the command will appear; however, when an HDLM device is specified, the message will not appear.
