# echo 2000?8c+8x|adb /dev/dsk/c3t2d0s2
adb: warning: /dev/dsk/c3t2d0s2: Unknown file type.

If you are on 11.23, you probably need to use "adb -o ...".
A bunch of similar threads, some with scripts:

Re: pvid, vgid etc
One nice thing about using 'xd' to read the physical disk is that you are reading the disk signiture (VGID and PVID) from the disk rather than "asking" the kernel (with 'adb') what it cached when the volume was last activated. An unactivated volume will not return its VGID with the 'adb' method.
In one of the thead's Dennis cited, I explained the system ID (From 'uname'), the timestamp and the VGID and PVID fields:

Re: pvid, vgid etc
Both methods should return the same value, if you can figure out the cryptic adb command. adb should operate directly on the file.
