Re: HSM problem

        Richard,
        Yes, I just install HSM two weeks ago. But I have restarted the
Solaris machine several times and the kernel extension has been added.
        Indeed, the rest of the file systems have been created with the same
process at the same time, and they work okey.
        When I do "df" the output is:
        # df
/                  (/dev/dsk/c0t0d0s0 ): 1038738 blocks   357605 files

        None of them are mounted twice. I understand that AIX and Solaris
does not work the same with this.
        Thank you very much,
        Eva
