Appendix A. Creating the NVRAM alias for the Jaz disk drive

The Sun workstation uses a long and complicated device path to address devcies at the boot prompt. To discover the device path for the Jaz drive, first start the system on a normal boot. As soon as the boot device appears on the screen, 

/iommu/sbus/espdma@5,8400000/esp@5,8800000/sd@3,0

stop the system by pressing L1 (or Stop) and "a" simultaneously. The last segment of the boot device path, sd@3,0, is the SCSI device, where 3 is the target ID. Replace the 3 with the SCSI target ID of the Jaz drive (usually 4) to get the Jaz device path:

/iommu/sbus/espdma@5,8400000/esp@5,8800000/sd@4,0

This path can be stored in NVRAM as an alias named jaz:

boot nvalias jaz /iommu/sbus/espdma@5,8400000/esp@5,8800000/sd@4,0
