master server shown offline

[liuyang]

Hi, we have cluster master servers which has two nodes: node A (active) and node B (passive). The OS of the master servers is Windows 2008 R2 SP1 and NBU version is 7.1. Recently we tried to failover from node A to node B. However, after the failover, the NetBackup Device Manager service in node B is stopped. In NBU console, under Devices-> Media Servers, the status of node B is shown as offline. I tried to manually start the device manager service but node B is still shown offline. Has anyone have any ideas regarding this? Thanks in advance.

Thanks for your reply.

It just shows offline. I think it means offline for both disk and tape. Which parameter should I use to bring it online?

Have you verified that same license keys have been added to both nodes?
NBU Patch levels same on both nodes?

Was Device config wizard run on node B during initial setup?
EMM database keeps device info for individual node names. 
During initial setup, Device wizard must be run on active node, then failover to 2nd node and run Device wizard again.

Please post output of:
nbemmcmd -listhosts -verbose
nbemmcmd -getemmserver

Thanks for the replies. FYI, the issue was resolved by re-ran the Device Wizard from active node.

Wow! Only two months later?

This means that Device Config Wizard was never run on node 2 during initial setup? 
Glad I could point you in the right direction with questions in my post above:
