Ad. Q1: There are three ways (two if it is Solaris 8 or 9) in which Solaris can mirror root disk:
1. SVM - Solaris Volume Manager. To check if it is the case do the following:
Code:
df -h /

If "Filesystem" is something like /dev/md/dsk/d0 then you have root on SVM volume. Next check if it is mirror by doing:
Code:
metastat d0

d0 might be something else in your case.
2. ZFS - only for Solaris 10. Check it the same way:
Code:
df -h /

If it says something like rpool/ROOT/sol_10_u9_zfs (last part will be different), then you have ZFS root. To check if it is mirrored do:
Code:
zpool status rpool

3. Hardware RAID. It is the least common. I only encountered this kind of mirroring on some T2000 servers. Output of df -h / will look like root was placed on local disk slice (c0t0d0s0), but when you do
Code:
raidctl -l

it will list that disk (c0t0d0) as volume built from physical disks.
Ad. Q2: most often external disks are SAN LUNS, which look like this in format output: "c5t60080E8004D2A6000000A1A500000D21d0". Anything else (much shorter, like c0t1d0) is most likely internal disk.
Ad. Q3: You cannot tell from format's output if the disk is part of a mirror.
