Map sd?/sdd? names to Solaris disk names?
Some commands in Solaris (such as iostat) report disk related information using disk names such as sd0 or sdd2. Is there a consistent way to map these names back to the standard /dev/dsk/c?t?d?s? disk names in Solaris?
Edit: As Amit points out, iostat -n produces device names such as eg c0t0d0s0 instead of sd0. But how do I found out that sd0 actually is c0t0d0s0? I'm looking for something that produces a list like this:
sd0=/dev/dsk/c0t0d0s0 ... sdd2=/dev/dsk/c1t0d0s4 ...Maybe I could run iostat twice (with and without -n) and then join up the results and hope that the number of lines and device sorting produced by iostat is identical between the two runs?
Answer
Following Amit's idea to answer my own question, this is what I have come up with:
iostat -x|tail -n +3|awk '{print $1}'>/tmp/f0.txt.$$
iostat -nx|tail -n +3|awk '{print "/dev/dsk/"$11}'>/tmp/f1.txt.$$
paste -d= /tmp/f[01].txt.$$
rm /tmp/f[01].txt.$$
Running this on a Solaris 10 server gives the following output:
sd0=/dev/dsk/c0t0d0
sd1=/dev/dsk/c0t1d0
sd4=/dev/dsk/c0t4d0
sd6=/dev/dsk/c0t6d0
sd15=/dev/dsk/c1t0d0
sd16=/dev/dsk/c1t1d0
sd21=/dev/dsk/c1t6d0
ssd0=/dev/dsk/c2t1d0
ssd1=/dev/dsk/c3t5d0
ssd3=/dev/dsk/c3t6d0
ssd4=/dev/dsk/c3t22d0
ssd5=/dev/dsk/c3t20d0
ssd7=/dev/dsk/c3t21d0
ssd8=/dev/dsk/c3t2d0
ssd18=/dev/dsk/c3t3d0
ssd19=/dev/dsk/c3t4d0
ssd28=/dev/dsk/c3t0d0
ssd29=/dev/dsk/c3t18d0
ssd30=/dev/dsk/c3t17d0
ssd32=/dev/dsk/c3t16d0
ssd33=/dev/dsk/c3t19d0
ssd34=/dev/dsk/c3t1d0
The solution is not very elegant (it's not a one-liner), but it seems to work.
