When the drives have been

When the drives have been swapped out you will find that even though the serial numbers stay the same the scsi enquiry will change due to different firmware so you will still need to run the wizard - you will also need to check your tape drivers are Ok on the media servers .. but still a lot easier that starting all over

What is your tape library?

What is your tape library? Some libraries never show the real drive serial number but mask it so that drive changes are less disruptive - it may be you need to do nothing more than re-run the device wizard to update your config

If however it does not mask then i would prefer to delete all existing drives (restarting services when prompted) and then run the device wizard once the new ones are installed - making sure that they are the same denisty as the originals (hcart2 or whatever) so that you can read you existing tapes for restore purposes.

If the drives are in the same library there should be no need to delete the robot or do anything with the inventory other than do an update once the tapes have been changed out

Hope this helps

Mark is absloutely right. If

Mark is absloutely right. If you have IBM tape Library make sure you see the serial number and the Drive Firmware is latest. I had faced issue on one of Tape Drive which I replace on IBM Tape Libraries. It won't show the new drive. So make sure the procedure is followed and you see all the Drives.

For Tapes just inventory will not suffice, you will have to label the Tapes as well if they are brand new.

You dont need to label new

You dont need to label new tapes .. NetBackup will label them the first time they get used

Good stuff - i500 libraries

Good stuff - i500 libraries usually do mask the serial numbers by default - just need to run the wizard to update the scsi enquiry strings

i have big trouble with the

i have big trouble with the new LT06 Drive, Netbackup can reade and write only on one of the Drive, but the second Drive when start backup, go to (under Device Monitor) Control State: Down-TLD. I dont no why thies happend?

I have remove old Drive from NBU side over Java Console, and than run tpautoconf -a, stopltid and (start) ltid now.

Any idee?

Master and Media Server is SLES 10,

On the OS

  scsi.bus = 0 (0x0)
  scsi.host = 11 (0xb)
  scsi.lun = 0 (0x0)
  scsi.model = 'ULTRIUM-TD4'
  scsi.target = 1 (0x1)
  scsi.type = 'tape'
  scsi.vendor = 'IBM'

All Drives looks so, and the Model is Ultrium-td4 and must be have ULTRIUM-TD6, so locks on the NBU side: scan

I am battling to understand

I am battling to understand your last question...

but can i put all new Tapes in the Drive bevor start wizzard on the NBU side? 

 

Are Tapes referring to backup media? As in cartridges? Like this picture?  

And is Drive referring to the new LTO6 tape drive? Like this picture ?

Maybe you want to put the tapes (backup media) in the robot/library?

And which wizard are you referring to?
Device Config Wizard? 
Robot Inventory?

Please help us to understand your question?
