Hi All,

I have some doubts(questions) elated to netbackup .

If you know kindly share it .

1.If you have a SCSI attached robot and in device monitor you see the drives marked as AVR, what does that mean and how would you fix it?
 

2) If you wanted to know what IP address netbackup was using to perform backups what command would you run and where would you run it?

3 How do you find a disk based image via the command line and then delete it?

4) How do you import an NBU image that has been written to a disk storage unit?

5) What are the critical catalogs or databases on a Media Server?

6) How would you tune NetBackup to increase backup performance?

7) How to check tape is bad

8) How to check the tape is already expired or not?

9) Media has been already expired, How to find out?

10) How to check tape is in cap?

11) how can I recover an corrupted image?

12 )What is OTM? TIR?

13) What format does NetBackup write the tape in?

Thanks,

Sagar

1.If you have a SCSI attached robot and in device monitor you see the drives marked as AVR, what does that mean and how would you fix it?

It means either the robot control host has lost communication with the robot, or, the drives have  been configured as non- robotic.  Either fix the commns issue, or rconfigure the drives to be in the robot.
 

2) If you wanted to know what IP address netbackup was using to perform backups what command would you run and where would you run it?

bptestbpcd -host <client name> would work, run from the media server

3 How do you find a disk based image via the command line and then delete it?

bpimmedia -disk

bpexpdate -d 0 -backupid <backup id>
 

4) How do you import an NBU image that has been written to a disk storage unit?

Same as you do for tape

5) What are the critical catalogs or databases on a Media Server?

None - they are all on the EMM server

6) How would you tune NetBackup to increase backup performance?

Go through the Tuning and Performance manual

7) How to check tape is bad

bptm log/ system log/ /usr/openv/netbackup/db/media/errors file

8) How to check the tape is already expired or not?

bpmedialist -m <media id>

9) Media has been already expired, How to find out?

bpmedialist -m <media id>

10) How to check tape is in cap?

Run robtest, use command

s p

11) how can I recover an corrupted image

Yuu could try expiring the image and reimporting

12 )What is OTM? TIR?'

TIR is 'True image recovery@

OTM is Open Transaction Manager

13) What format does NetBackup write the tape in?

tar

4) How do you import an NBU image that has been written to a disk storage unit?

Same as you do for tape but you need to mentioned disk STU path.
