VTL not identified

guys i have just had an HP eml e series VTL presented to my backup server and it is unclaimed.
i have added the STAPE drivers and module into the kernel and rebooted and still it is unclaimed.
any ideas is there a specific driver i need or am i missing some thing.
regards

Re: VTL not identified

Hi Andrew,

I assume the tape drives are CLAIMED now, but the change is not.

You need to configure the "schgr" driver into the kernel.

Hope this helps!

Re: VTL not identified

Hi,
If you see on the ioscan that the vtl is unknow as we suspect go to
SAM
kernel configuration
driver select and actions add driver schgr
finally process new kernel
reboot

Re: VTL not identified

I cannot see it too, because there is ioscan attached.

;-)


Did you adjust your library configuration, e.g. library partitions presented to this server?

Hope this helps!

Re: VTL not identified

Re: VTL not identified

Similar to a disk array you can devide the library into several virtual libraries and present the robot and/or certain drives to a specific host.

Nothing presented = nothing visible.


Hope this helps!

Re: VTL not identified

If you see NO_HW in ioscan, the device was there, but it isn't any longer.

Did your SAN guys check the library and zoning config?

Hope this helps!

Torsten.

Re: VTL not identified

aparently zoning etc all OK and we have never seen anything apart from NO_HW so i still believe the san is not presenting to unix box in a way that it understands, this is the only possible thing it can be in my mind.
anybody got any further thoughts?

Re: VTL not identified

If you see NO_HW it **WAS** visible.

You should use commandview TL and check the library configuration now.

Hope this helps!
