Hi All,
Can you please tell me what is the use of tape intialization option? is it advisable to initialize the tape every time before we take a backup. Please explain in detail. Advance thanks
regards,
Bala
brbackup needs to know if it will backup on the good tape. it obviously cannot read the physical label, so, it created one small file at the beginning of the tape. this file contains the tape's name.
so, when a backup starts, it read the first file, makes sure that this tape has a valid label. if so, it starts backups after the first file on tape.
so, if you do not label the tape, brbackup won<t be able to start because it will think that this tape is invalid... or it won<t start becasue it does not want to possibility overwrite a tape with some other kind of of backup on it.

Hi,
It's not advisable to initiaize tape every time before backup.
Use Brtools to initialize the TAPE.Login as <sid>adm
give command
Brtools
choose option
Backup & database copy
than
choose option
Additional Function
than choose option
Initialization of BRBACKUP tape volumes
than you get the following screen
Options for initialization of BRBACKUP tape volumes
1 - BRBACKUP profile (profile) ....... [initDEV.sap]
2 - Initialization type (initialize) . [rename]
3 ~ Number of volumes (number) ....... []
4 - Confirmation mode (confirm) ...... [yes]
5 - Message language (language) ...... [E]
6 ~ Tape volume names (volume) ....... [DEVB01]
7 - BRBACKUP command line (command) .. [-p initDEV.sap -i -l E -v DEVB01]
choose option 2 & give name force & enter
choose option 6 & give the TAPE(EX:-DEVB01) name.
(Check tape name in your init<sid>.SAP file )
& than press c & c & c........
