The tape drive can be connected to system online. But there are chances that things may wrong this way- like SCSI resets, lbolt errors.

Shutdown the system, connect tape drive. Check all connections, cables and power on the systems.

Once system comes up, you should be able to see tape drive as calimed in ioscan output.

Try this before a reboot

Try ioscan -fnCtape.

insf -ev -Ctape.

IF you do not see the tape, it could be problem with hardware.

As I said earlier, once you connect the tape drive and do ioscan, you should be able to see the tape drive as claimed.

I would advise you to recheck cable connections, tape drive.

If it is not working, it is problem with hardware.

Go into SAM, and look under tape devices. In there, you'll see an option to scan for new tape drives. If this doesn't see it, then it can't be seen from the OS for some other reason, and you'll need to go back to basics and check SCSI compatability and connectivity etc.

It could be a lot of things, be very careful if you are going to reconnect the cables, a bent pin could ruin the HBA. Once you have the tape connected, and fully powered on, do the following:

If you know the hardware address of the device, try removing any special device files that are currently associated with it as there could be some corruption

rmsf -H

This will remove the device files associated witht the supplied hardware address.

ioscan -f

This will scan the entire system, and look at all devices.

insf -e

This will install the special device files associated with any hardware that was newly attached.
