Drivers

[Shailesh_raj72]

Hi All,

Master srver - 7.6.0.1

OS - Linux

No media server.

I have tape library I did the zoning with SAN switches.

So I need driver to communicate the OS and hardware..

[Marianne]

Only buit-in OS drivers are needed. 

See the Linux chapter in NetBackup Device Configuration Guide

Commands that you can use on Linux without even featuring netbackup to see if output shows your tape drives.

# hwinfo --tape

# cat -s /proc/scsi/scsi

Netbackup featured commands to show output:

# scan

# tpconfig -l

What version of Linux and kernel you running?

And list hardware library and tape model please.

Kernal version:

Linux version

[Shailesh_raj72]

Hardware is Oracle SL150 Tape library

You need to check that the OS is seeing devices with:
# cat /proc/scsi/scsi

If devices are not seen, you need to check zoning and confirm OS drivers.

Nothing to be done in NBU if OS cannot see devices.

PS: 
I see in above output a reference to RHEL 4.4.7?
Is this the same in /etc/redhat-release?

According to NBU OS SCL, NetBackup 7.5 and later does not support this Operating System on this CPU Architecture.
You need RHEL 5 or 6.

Thanks Marianne

pls find the below output.

cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)

cat /proc/scsi/scsi

Expect to see some tape devices under there...

What does the output of the following give

# scan

# tpconfig -l

# ls -al /sys/class/scsi_changer/

# ls -al /sys/class/scsi_tape/

If you are expecting to see tape devices then the OS can't either.

Sort that part out first before continuing from the NetBackup management side. So...

Revisit Zoning of the backup host and the tape drives on your SAN switches and then check cable connections etc. 

[Marianne]

The reason why scan is not seeing anything is because your OS is not seeing the devices.

The reason why tpconfig output is empty is because no devices are configured in NBU yet.

You need to check zoning and OS.

Just to clarify the commands mentioned in this post.

cat /proc/scsi/scsi   - shows what the os can see

scan - shows what devices responded to scsi inquire command that can be seen by the os

tpconfig -d   - shows what is configured in NBU

The commands have to work in the order listed above - unless scan works, forget tpconfig -d.  Unless cat /proc/scsi/scsi works, forget scan, it won't show anything until the OS does.

For the record, scan is a Symantec command but not really a NetBackup command, it doesn't use NBU when it is run, and in fact will run even with NBU shutdown.

Thanks all...

issue has been resolved now...
