ITSM 5.2.2 does support EMC Centera.
No - you cannot do the SET ARCHIVERETENTIONPROTECTION ON command if you
have archive/backup data in the database. It MUST be cleared before the
command can be issued.

Bill,
JFS journalling doesn't journal data changes, only changes to metadata. So in a
filesystem with lots of file and directory creates and deletes its useful. In the TSM
situation, such changes are rare, and so JFS doesn't buy you a lot in terms of
recoverability.

Hi, Joni.
All of these questions are answerable via risk/benefit analysis and the
answers are all specific to your shop.
We have 2 separate SANs, and each drive plugs into both SANs. Each of our

interface on each SAN, so

The numbers TSM reports are ALL from the server's point of view.
A "filling" tape will have a fixed (and pretty meaningless) EST CAP
determined by the device class until the tape gets marked FULL. Then TSM
changes EST CAP to the number of bytes actually written to the tape.

Relatively simple. The "EST CAP" is set when you define the DEVCLASS,

I'll show my ignorance, but I didn't think TSM supported the Centera.
I thought access to the Centerra was via a specific API EMC has written
for it. To me, this implies that it would require a special program to

Hi Andy!

Has anyone got TSM working together with the EMC Centera?
Did you manage to get it working with SET ARCHIVERETENTIONPROTECTION ON

Jack, you can do a "backup stg maxpr=1 preview=yes

Hi,
we tested a migrate install from w2k --> w2k3 using TSM 5.2. The upgrade itself

You have to install the drivers through the w2k3 devices
