If you are using Kernel Zones
-bash-5.2$ zoneadm list -v
ID NAME STATUS PATH BRAND IP
0 global running / solaris shared
1 v0182 running - solaris-kz excl
It is now easier on the global zone to analyze
the I/O of only the disks used by kernel zones
using the wildcard (v0182*) and the new -b (backend) flag
-bash-5.2$ iostat -xnzb -Td v0182* 5 3
