Configuring VNX5300 VTLU with TSM
Hello. I have an EMC VNX5300. We have a few NAS CIFS and NFS shares. I backup them through NDMP to a TSM server on a physical library. I have a Quantum iscalar 80 robotics. everything works fine. I would like to use the VNX5300 embedded VTLU in the same manner. I defined the library as a vtl one. I used the example for TSM in page 20 of the Configuring NDMP Backup On Disk on VNX 7.1. I have an issue when I create a path to the libray with the command : define path VNX1 TESTLIB srctype=datamover desttype=library device=c0t0l0. The error message is : ANR8418E DEFINE PATH: An I/O error occurred while accessing library TESTLIB. When I use a false device name, I have this error message : ANR1737E DEFINE PATH: Device name c0t0l1 specified is invalid.I suppose the the TSM server communicates well with the NDMP server but cannot manage it. Has anyone an idea how to resolve this problem ? If this is a driver problem, can I emulate my physical robotics in the embedded VNX VTLU ? Any help is appreciated. Thank you.

Are you sure the VNX VTLU is what you want ?
It doesn’t have any relation to your physical library

Server_devconfig will only show physical tape drives – not virtual ones
See the NDMP2D manual
[nasadmin@vnx1 ~]$ server_vtlu server_2 -tlu -list
server_2 :
id vendor product revision serial_number device_name
4 ATL p1000 1.01 IhbVsML2k5 c0t0l0I used the device name c0t0l0 listed above in my definition of the TSM library.
Since this is an EMC forum, I modify a bit my question : is it possible to emulate a Quantum Scalar i80 with an HP Ultirum drives with the VNX5300 VTLU ? Is there a list of all the products that could be emulated in the VNX5300 VTLU (matrix document) ?

Remember – this is NOT a Fibre-Channel or SCSI library emulation – it is purely NDMP over IP
Yes, you can name your drive whatever you like – it doesn’t really matter.
You wont be doing any SCSI ioctls to it
Nor do things like block size matter like they do with physical tape drives
All that matters is the tape size.

i have not configured VTLU with TSM, has VTLU been presented to your datamovers so you can get the device names ?
server_devconfig server_2 -list -scsi -nondisks -all
