ITSM for hardware is nice if I'm using ESS.  
 
But the following link does not address what to do if I'm using Hitachi, EMC, 
HP, FaStT?
 
Best Regards,
James

        To add to what Wanda is saying:
        
        When a FlashCopy is initiated, the DB/Mail server that you are flashing
        should be quiesced prior to the FlashCopy being initiated.
        
        FlashCopy can also be expensive.

                I am not an expert in this area, but I think there are several
        issues
                involved.
               
                FlashCopy is taking a physical image of the VOLUME(s) involved.
                The Data Base manager doesn't know you're doing it.
               
                SO while it's easy and low cost to do the FlashCopy (it's pretty
        much an
                outboard hardware process), it doesn't copy or clear the logs
        that the DB
                management system uses.
               
                So the real question, as usual, WHAT are your recovery
        requirements?
                What are you going to do with that FlashCopy if somebody wants
        to restore
                the data base?
               
                If what they want is the ability to back out a bad transaction,
        you can do
                that with Oracle (for example), by restoring from the last full
        and then
                rolling forward from the journal, but you won't necessarily have
        a copy of
                the journal if all you have is a FlashCOpy.
               
                And Exchange and SQL server (I think) work like the TSM DB, when
        you take
                the DB backup, they clear their transaction logs.  So you would
        have to have
                some way to sync up your logs, if you used FlashCopy instead.
               
                SO you gotta work those issues out.  FlashCopy certainly is a
        great option
                for a DB manager that doesn't HAVE a TDP available, because you
        can  stop
                your DB for just a few SECONDS and take a FlashCopy, instead of
        having the
                DB down for an hour to dump the volume as a flat file.
               
                Talk to your DBA about the recovery requirements for your
        particular DB's.

                Subject: TDP vs. FlashCopy thoughts
               
               
                Given that TSM has TDP for many databases and that TDP can do
                incremental backups at the record level. What are the thoughts
                for using TDB vs. using FlashCopy on an ESS/Shark? The FlashCopy
                must backup the entire database each time, unless the backup
                database could be mounted to a secondary server that could then
                start TDP on the backup copy...?
