Disk Devices in SAR output

Question

sar -d gives me the following output:
sd0 0 0.0 4 0 0.0 0.0
sd1 1 0.0 2 55 0.0 14.3
sd1,a 1 0.0 2 45 0.0 18.0
sd1,c 0 0.0 0 0 0.0 0.2
sd1,i 0 0.0 0 0 0.0 0.1
sd1,q 0 0.0 0 0 0.0 0.0
sd1,r 0 0.0 0 0 0.0 0.0
sd1,s 0 0.0 0 0 0.0 0.0
sd2 1 0.0 2 47 0.0 19.0
sd2,a 1 0.0 2 47 0.0 19.0
sd2,c 0 0.0 0 0 0.0 0.0
sd2,i 0 0.0 0 0 0.0 0.0
sd2,q 0 0.0 0 0 0.0 0.0
sd2,r 0 0.0 0 0 0.0 0.0
I know which "sd" device corresponds to which disk devices.
But, what are the sd1,a / sd1,c / sd1,i / sd1,q.... devices?
It doesn't make sense that they are paritions because sd1 and sd2 are my two disks that make up my mirrored root zpool. I don't have 6 paritions on these disks.

Answer 1

Indeed they are partitions. though you might not have allocated any size in that partition. But partition still there. You can map sd to ctd easily by using
ls -l /dev/dsk/* and grep for sd devices.
