When multiple stripes are used with dump database or dump transaction, each stripe creates a separate backup object at the TSM.
You can use the same or different backup object names for multiple stripes when TSM handles the backup media. In this example, each stripe has the same name. TSM uses a low-level identifier to distinguish between each backup object, for example, obj.2. See the error log later in this section.
If TSM is supported at your site, you can use the same
or different names for each stripe. If TSM is not supported at your
site, you must use different names for each stripe.
For example, to dump “testdb” using multiple stripes with the same stripe object name “obj”, enter:
dump database testdb to "syb_tsm::obj" stripe on "syb_tsm::obj" stripe on "syb_tsm::obj" stripe on "syb_tsm::obj" stripe on "syb_tsm::obj"
In this example, Backup Server provides uniqueness for TSM backup objects by appending the stripe identifier to the supplied backup object name “obj”. Check the Backup Server error log to verify that the TSM low-level backup object name is unique for each stripe.

Check the Backup Server error log to see the TSM backup object names and IDs. Check the complete Backup Server error log attached as well. The Backup Server displays this information:
Oct 1 14:37:43 2009: A00: Database 'testdb' dumped. Tivoli Storage Manager backup object name: fs = /demo_srv1, high = /testdb.DB, low = /obj.0, Copyids: (0, 80898).

To load “obj” to the same database, enter:
load database testdb from "syb_tsm::obj" stripe on "syb_tsm::obj" stripe on "syb_tsm::obj" stripe on "syb_tsm::obj" stripe on "syb_tsm::obj"
To dump “testdb” using multiple stripes with different strip object names, enter:
dump database testdb to "syb_tsm::obj0" stripe on "syb_tsm_obj1" stripe on "syb_tsm_obj2" stripe on "syb_tsm_obj3" stripe on "syb_tsm_obj4"
In this example, each stripe has a unique backup object name; Backup Server appends a stripe identifier to each one.
