If you try and use a higher density in a lower density drive, I think (!!)
it would treat it as the lower density.

You will need to contact the company that supplied the robot and confirm if
it is LTO3 drives - if so, get LTO3 Media

Also, my name is Simon. My last name is Weaver (and you managed to spell
that wrong too!).  :-)

Hi Waever,
I agree with you that netbackup will refuse any other media type except the
one the drive matches. My question is whether NetBackup will adjust the
density to the type of the drive (equal type of the media). 

I mean if I set drive density to hcart2 for hcart3 drive, what would the
capacity for that media be? Is it like hcart3 regardless of the setting in
netbackup ? I will use T10000A FC. I am thinking what shoud the media type
be? I am  thinking to set the media type to hcart3. However, on the other
location, there is a robot in LTO3 format. I am afraid that if that medias
came to  that site and they were put to that library, T10000A would try to
mount it and T10000A would be damaged due to that. I am thinking to set the
media type to one which is absent from any other location. So, Could you
please explain us what the drive type means in netbackup world? How is it
important? 

Regards,

If I understand the question correctly, if you set a drive which is usually
HCART3 and then change to HCART2, NetBackup treats the drive as HCART2 - but
I do not think it will load any HCART3 tapes in the robot.

The reason why I say this, is because I had to perform a restore using an
old HCART tape - drives are set for HCART3 - if the density is not changed,
Netbackup refuses the restore.

If I change the density to HCART, netbackup uses the drive for the restore
from HCART tape.

HTH

Hi All,
I have a question. Is the NetBackup adjusting density according to the drive
type? I mean if I set drive density to hcart2 for hcart3 drive, what would
the capacity for that media? Is it like hcart3 regardless of the setting in
netbackup?

Regards,
