Both HP-UX and Sun Solars uses almost same device file naming convention. Typically it look like as follows:
Let us try to understand what those letters
- c - Instance number of interface card
- t - SCSI target address
- d - Device number aka SCSI LUN
Use ioscan command to get information about your device under HP-UX. A block device file is always in /dev/dsk and a character device file in /dev/rdsk directory.
- /dev/dsk/c0t5d0 - Block device file
- /dev/rdsk/c0t5d0 - Raw device file
I just wish both of them were use device file naming convention like linux (/dev/sda1).
