Dear ADSM friends,

We are starting an ADSM implementation on at least 10 SUN (Solaris 2.4/2.5
Machines). I am using ADSM server for AIX 4.2 (2.1.5.6) and Sun ADSM ver.
2.1.0.5. I read a note concerning symboliclinks and I tried a simple test.
What I got from that
took me both curious and perplexed.

Here it is what I did.:

on the UNIX prompt:

# /usr/lpp/adsm/bin > ln -s /tmp linkdir        (create a symbolic link pointing
to /tmp )
# ls -la linkdir
lrwx--x-rw- linkdir -> /tmp                     ( symbolic link is there !)
# cd linkdir
# pwd
/usr/lpp/adsm/bin/linkdir
# mkdir links
# cd links
# echo > s                              ( create a simple file )
# cd ../..
# pwd
/usr/lpp/adsm/bin
# dsmc
...... ADSM "welcome"headers ... ver 2.1.5.6 .....
# dsmc> sel /usr/lpp/adsm/bin/linkdir/* -subdir=yes     ( selective all from
this)

...... and all files form linkdir went to ADSM server perfectly ... :)

# dsmc> quit

NOW: I removed the dir link and 'unlink' the directory as follows:

# pwd
/usr/lpp/adsm/bin
# cd linkdir
# rm -r links           ( delete all files from this directory )
# cd ..
# unlink linkdir                ( now we do not have a symbolic dir anymore )
# dsmc
.... ADSM banners again ...... ver. 2.1.5.6
# dsmc> restore /usr/lpp/adsm/bin/linkdir/*
# dsmc> quit

IF I list the directory, I can now see a REAL directory , i.e.:

# ls -la
drwx--x-rw- linkdir     , instead of (what I was thinking)

lrwx--x-rw- linkdir -> /tmp

I configured FOLLOWSYMBOLIC as 'NO' and then 'YES' ( I did all the process
for
both, not only the dsm.opt update).

I do not know if FOLLOWSYMBOLIC should do what I expected. If that is not
the
case, my question is :

        How could I restore a symboliclink-directory, that was deleted then?
(YES, I want the symbolic link instead of the recreation of a directory)



Thanks in advance.
