disk Commands disk initialize To initialize a SCSI disk for use with the currently opened controller, use the disk initialize command. This command writes data structures to the disk so that the controller can use the disk. Syntax disk initialize [/always{=boolean}] [/unconditional{=boolean}]{scsi_device} Parameters {scsi_device} Specifies the ID for the SCSI disk you want to prepare and initialize for controller use. A SCSI ID consists of a SCSI channel number (for example, 0, 1, 2, 3, etc.), SCSI device ID (0 through 15 inclusive), and SCSI device logical unit number (0 through 7 inclusive). For further details, see scsi_device on page 1-10. Switches /always{=boolean} Specifies whether to initialize the disk even if the disk has data on it. If you specify TRUE for this switch, the command initializes the disk even if it has data on it. If arrays on the disk have open files, this command cannot be used. In other words, you need to close all open files before you use this command to initialize a SCSI disk. The default behavior for the command is FALSE; that is, the disk initialize command does not initialize a disk that has data on it. Specifying /always overrides this behavior. 5-3
