Hello.
Is it available to share tape drive between adminserver and ndmphost usnig san switch?
we have 6 lto5 drives and will be attached to NDMP machine oracle ss7420.
Customer site doesn't have any client backup except nas data.

Reason why I ask that How to backup osb catalogdb to tape drive.
Is it okay to backup admin osb catalogdb as client or tape drive share is available?

Another question is that when we setup NDMP device, NDMP host can control robot or robot control have to assign to admin server or both availble?

Thanks.

    Yes this is available by design. You just configure the NAS with the mediaserver role and add a 2nd attach point to the device. You can then create schedules that restrict to those attach points. This allows you to share all drives between all media servers.

    For the robot I would let the admin server do that, just have the tape devices mapped to both. The robotic control is a pretty lightweight task.

    Here's an example of one of my configurations where the drive is shared between multiple media servers, Oracle Linux 4, Oracle Linux 5 and NetApp
