One thing you have to watch out for is that...
when you do that you alter the keys which TSM uses...
Key fields in various situations are NODE, FILE_SYSTEM (filespace_name),
directory path ie stuff between the mount point & where the file resides
(hl_name), FILE (ll_name)
Now you used to have /app/1st72gbarray/somedir/somefile
keys used to be
        app
        1st72gbarray/somedir
        somefile
now if you do what it seems you will do your keys will change as follows...
        app/1st72gbarray
        somedir
        somefile
So in the future you might have to do the following...
If looking for older copies of backups & archives use
        q backup {/app}/1st72gbarray/somedir/somefile
If looking for newer copies of backups & archives use
        q backup {/app/1st72gbarray}/somedir/somefile
Use the {} to designate what should constitute the ~file_system~ name

Oh, and I guess since it radically changes the keys, it goes without saying
that it will assume the new names are all new files...

There is the ability to rename your filesystems within TSM but I've never
specifically looked at the results of that action as it relates to the
issues mentioned above...

hope this helps,
later,

Hi TSMers

I have a question for you.

I'm running TSM 4.2.2.12 on a Solaris 2.7 machine. We are about to do some
reconfiguration of the file systems of one of our clients as follows.

At the moment we have one massive /app dir with loads of subdirs for
various applications (5 72GB disks software raided...yuk). What we are
looking at doing is making some of the dir's actual mount points. i.e. the
/app/users/fred would be copied to a new mount point making sure that all
file permissions, access dates etc remain unchanged, and then mount that
new file system as /app/users/fred (same as before).

Will TSM see this as completely new data, regardless of whether or not we
maintain the same dates, time stamp etc. If, so, is there a way round this?

Please feel free to ask for more info If I have been too vague.

Many thanks
