Important: What Operating System and version are you running?
What hardware do you have?

Posting hardware enquiry comands out of context means nothing without knowledge of the command syntax and the hardware.

What is the output from:
Code:
ls -lad /dev/whatever_your_device_is_called

This should produce a unique identity mappable to the SCSI ID given your knowledge of your Operating System and hardware configuration.

NAME

       io_redirect_dsf - redirect the persistent device special file from one device to a different device

SYNOPSIS

       old_hw_path new_hw_path

       old_dsf new_dsf

DESCRIPTION

       The command reassigns a persistent device special file (DSF) to a new device when both devices belong to the same class.  If the new device
       does not already exist, before reassigning it you must create the DSF by running either or (see insf(1M) and mksf(1M)).

       In the first form, the command accepts as input the lun hardware paths of the device to be replaced and the  new  device.   In  the  second
       form, the command accepts as input the persistent DSFs of the device to be replaced and the new device.

       Note: The device is inaccessible while the redirection is taking place.

   Options
       recognizes the following options:

	      Specify the hardware path of the device that is being replaced.
			     returns an error if old_hw_path is not a lun hardware path.

	      Specify the hardware path of the new device.
			     returns an error if new_hw_path is not a lun hardware path.

	      Specify the device special file of the device that is being replaced.
			     returns an error if old_dsf is not a persistent DSF.

	      Specify the device special file of the new device.
			     returns an error if new_dsf is not a persistent DSF.

RETURN VALUE

       Exit values are:

       Successful completion.

       An error condition occurred.

EXAMPLES

       Redirect the DSF with the hardware path at to point to the hardware path at Both disks belong to the class.
