Definitely prior to halt and your system maintenance, because if the
changes made to the system destroy something from your TSM structure... You
will be able to restore from that last DataBase backup. Also you might want
to monitor this DB backup, make sure it finishes successfully, and write
down yr Volume Serial (Volser) number just in case...
What about System Backups (AIX: sysback, mksysb) ? depending how important
is the changes made to the system you might want to take a system backup as
well.

Cheers.

Subject:  maintenance window/database backup



New to the TSM environment,,,so thanks for the forum and thanks in advance
for any assistance.
We have a maintenance window carved out roughly between 14:00 and 18:00.
Maintenance to our storage environment next week, which facilitates a TSM
down
between those hours. Should I perform that DB-BACKUP prior to the 14:00
HALT

or run the DB-BACKUP after I bring the system back up?
