Summary
In this chapter we discussed an example of a database restore scenario. You should now
know how to prepare and complete a database restore. In addition, you now understand that
the V5 approach of adding and deleting databases volumes for Tivoli Storage Manager
database relocation no longer works. Relocating server volumes requires a database restore
and results in server downtime. This makes planning in the beginning more important.
Remaining tasks at this point include the configuration of a mirror for the active log or the
definition of an archive log failover directory. However, at this point you should be able to
complete those steps with the information from the administrator’s reference guide and the
manual.
If you are interested in a review of other restore scenarios, refer to 6.3, “Recovery of a V6.1
Tivoli Storage Manager server” on page 128, where we discuss a DRM restore to a new
hardware box.
5.4.3 Increase database space
In case your database grows, you can use the EXTEND DBSPACE command to add
additional space to an existing installation. This requires a restart of the server for the change
to become active. See Example 5-47.
Example 5-47 Extend dbspace command
TSM:TIRAMISU>extend dbspace m:\tsmdb\dbdir3
ANR2017I Administrator SERVER_CONSOLE issued command: EXTEND DBSPACE
m:\tsmdb\dbdir3
ANR2592I Directory(ies) 'm:\tsmdb\dbdir3' has been defined in the database space.
TSM:TIRAMISU>q dbspace
ANR2017I Administrator SERVER_CONSOLE issued command: QUERY DBSPACE

Example 5-47 on page 111 documents how we submitted the EXTEND DBSPACE command
and subsequent QUERY DBSPACE and QUERY DB commands to show the directory
assigned to the database. However, in Example 5-48, you can see that the directory is just
empty.
Example 5-48 Database directory stays empty
G:\Program Files\tivoli\tsm\server1>dir m:\tsmdb\dbdir3
Volume in drive M is tsmdb3
Volume Serial Number is 1C55-D0C5
