Table 1-2  USP V Device Specifications (continued) 
   
 
Note 1: The availability of a specific USP V device type depends on the level of
microcode installed on the USP V system. 
 
   
 
Note 2: The category of a device (SCSI disk or FX) determines its volume 
usage. 
Table 1-3 shows the volume usage for SCSI disk devices and FX 
devices. The SCSI disk devices (OPEN-x, VLL, LUSE, VLL LUSE) are usually 
formatted with file systems for SGI IRIX operations. The FX devices (3390-
3A/B/C, OPEN-x-FXoto) must be installed as raw devices and can only 
accessed using FX. Do not create a partition or file system on any device used 
for FX operations.
