Hello
I'm writing to you cause I have a question about the NDMP option.
I already open a case but we are not convinced about what they told us. Could you help us please ?
The Issue:
We have a Backup server (Physical Dell server with W2012) with BE 2014, and we have a EMC VNX used for NAS.
We have a Tape Library HP MSL 2024 g3 SAN attached to the EMC and the Backup exec server through a SAN switch.
We Have Enterprise server Option for BE2014 which includes SSO.
FC switches are Cisco switches, Zoning is ok : the BE server can see the Tape Lib, and The VNX can see the Tape Lib as well.
We would like to have the capability to use this kind of NDMP backups : Direct NDMP In order to backup EMC NAS data to Tape library with direct stream between the storage area and the Tape Lib (as above)
The issue is when we launch a NDMP backup from the EMC to the Tape Lib, the DATA stream goes through the BE server instead of streaming data through FC between EMC and the HP Tape Lib.
Support, replied us :
The tape Library and the Backup Exec server are connected directly through the SAN switch. But the configuration We require is Tape Drive Directly connected to The NDMP and not the SAN switch, the NDMP Device Should be connected the SAN switch. I have Attached an image of Figure you shared , with the Modification required . could you please check it and Let me know if you have any queries .
The Tape Drive must be connected directly to the EMC Device, as you can see in the architecture diagram , the Backup Exec server and the NDMP filer are the only Devices attached directly to the switch. Here the"This requires the NDMP host to be SAN attached and zoned to see the tape library" Refers to the Proper Connectivity Between the NDMP and Tape drive I,e the Tape Drive should display under the NDMP Device when configured in the Backup exec console.
So, we tested that, deleted and reconfigure the NDMP device in BE, but now, as we expect, the Tape library have a Drive Offline, and nothing is display under the NDMP device.
Are you agree with the support answer? does the Tape Library really must be direct attached to the NDMP device and not SAN connected (through SAN Switch)?
In the Admin Guide we can read :You can use the following configurations to back up data from a NDMP server:[....¨] A configuration in which any storage device is attached to the same SAN as the Backup Exec server
I am at your disposal for further informations.
Thanks for your help,
Regards
