Netbackup 7.5 with DDBoost over FC - failed to create storage server
Hi,
I'm testing DDBoost over FC in a Netbackup 7.5.0.6 environment. Data Domain is configured and all zoning etc seems to be working fine.
The Data Domain FC name is "DFC-BASDD002". The media server I'm trying to persuade to use ddboost over fc is Win2003 R2 64bit and already works an an IP server using ddboost plugin 2.6.3.1-439355.
Data Domain is visible to the windows OS but is showing up in device manager in "Other Devices" with a question mark:
When I try the netbackup command to register the datadomain fc it fails:
nbdevconfig -creatests -stype DataDomain -storage_server DFC-BASDD002 -media_server dwb004.dcsit.net
RDSM has encountered an issue with STS where the server was not found: getStorageServerInfo
Failed to create storage server DFC-BASDD002, invalid command parameter
What am I doing wrong?
Thanks

For any lost souls who stumble upon this, the problem was Powerpath 5.5 was clashing with the fibre channel link with Data Domain. Standard fix for this is to:
1. Disable Migration Enabler and Encryption Module in PowerPath.
2. Disable the System device EMC PowerPath Generic Purpose Extension (GPX Extension). To Disable GPX Extension in PowerPath, go to Device Manager > System Devices > right-click EMC PowerPath Generic Purpose Extension > disable > reboot host.
3. Reboot media server.
4. Update disk pool in NBU.
When i did this on Win 2003 R2 x64 and Powerpath 5.5 it killed the server - got stuck in a reboot cycle and had to invoke last known good config to return to a working server. EMC advised to upgrade to Powerpath 5.7, then apply above. This worked and Data Domain shows correctly on the server and the above Netbackup commands ran fine.
Cheers
