Hello,

I am having trouble interpreting the output of the
sar command with the -d flag. The DEV column major/
minor node numbers do not seem to logically correlate
to the device node files major/minor numbers:

> sar -d

17:27:33          DEV       tps    blks/s
17:27:34       dev8-0      5.00     64.00
17:27:34       dev8-1    384.00  89872.00
17:27:34       dev8-2      0.00      0.00
17:27:34       dev8-3      0.00      0.00
17:27:34       dev8-4      0.00      0.00

output of various ls -l on device node files:

brw-rw----    1 root     disk       8,   0 Mar 20  2002 /dev/sda

brw-rw----    1 root     disk       8,  16 Mar 20  2002 /dev/sdb

brw-rw----    1 root     disk       8,   1 Mar 20  2002 /dev/sda1

Is /dev/sda1 the output in dev8-1, or is this /dev/sdb and the 
minor number 16 gets truncated to 1?
