Finding the Status of Existing SCSI Bus Addresses

Before you attach a new SCSI driv e, to ensure that the SCSI bus address of your device is currently unused, you can use SAM, or y ou can use the ioscan tool to help determine whic h devices are currently connected. To determine the currently connected SCSI bus IDs, en ter the following command line:

/etc/ioscan -fb

The result will be a displa y of information, suc h as the following:

For example, the SCSI bus address for the \MICR OP" disk device is in the fourth column of its hardw are address as \ 6" (2.0.1. 6 .0). If you were installing another disk, for ￿le system use, it w ould best be accessed at the adjacent SCSI bus address in the \scanning" order, \ 5". SAM would help you determine where to put it when y ou did the installation.
