We support just one region for the file, but I think you want to use the -D
option on xfsrestore.
Now you've reminded me of something else...
You're probably using dm_set_dmattr() to attach HSM-specific info to the file.
Our DMAPI implementation actually uses extended attributes to store that info.
Because this is HSM-specific info, only your HSM can decode it. Now look at
the -a option on xfsdump.
That -a option would be useful to you, I'll bet. To do that, xfsdump knows
how to decode the HSM-specific info that comes from our own HSM, "DMF".
However, It doesn't know how to decode the info from your HSM. It may be time
for you to submit some code to xfsdump.
In the xfsdump and xfsrestore manpages the -A option is described from a DMF
perspective, but I don't believe this is DMF-specific.
