prtvtoc /dev/rdsk/c0t0d0s2 | fmthard s - /dev/rdsk/c0t1d0s2

replacing the c0t0d0s2 with the appropriate drive reference.

This is a quick way to get the same exact partitioning onto two
like drives, as well; we use it all the time for LVM setup.

Likely as not, the A1000 is reserving some disk area for info
regarding the disk's location in the array, similar to how Veritas
Volume Manager "takes over" the entire disk, since it's a disk-
based LVM.  Solstice Disk Suite, aka Solaris SVM is a partition-
based LVM.
