Hmm.., normaly I'd say yes, but I'm not certain here. If you look at
the "sd" line, the figure right after the name of the disk is the offset
on the disk (although technically its the offset into the public region
of the disk). The -B0 is at a high offset, so it's not the boot sector.
If anything, it would be rootdg01-01 and rootmirror-01.
Now, under normal circumstances, you may have already allocated the boot
sector to an in-use slice. If the swap slice started at cylinder zero,
this would be true.
UFS filesystems and swap devices do not write to the first 16 block,
just in case the VTOC or boot sectors are at the beginning. But if
something else were using the device (say a database), then we wouldn't
want the sector to be there.

You'd need to verify that you have an OBP alias for 'rootmirror'
configured (sometimes VxVM sets it up as 'vx-rootmirror'). If so, yes.
