When trying to create a snapshot using a raw metadevice I get an error:

# fssnap -F ufs -o raw,bs=/snapshot1,unlink /dev/md/rdsk/d7
fssnap: ioctl: error 25: Inappropriate ioctl for device

But you can create a snapshot of a raw slice: /dev/rdsk/c0t0d0s7

Anyone know how to create a snapshot using a metadevice? The reason is because incremental backups of snapshots need to read the raw device, from what I read, whereas a full backup from a snapshot doesn't need to and you can just specify the filesystem (e.g., /export/home).

I could open a case with Sun but wondering if anyone knows.

Thanks
