Inventory Window does not show any robots in Java Console
Hi Experts,
Environment:
Master and Media servers running on Linux, NBU version 7.6.0.2.
Tape Libraries: StorageTek SL3000, Firmware 3.61
We recently replaced LTO4 Tape Drives with LTO6 Tape Drives on our 2 STK SL3000 Tape libraries. The upgrade of Drives was done 1 week apart for each library. First upgrade went ahead without any issues but after the upgrade of 2nd library we were not able to scan tape drives and Robots. We Engaged Symantec Support and they did some changes in the Device Mappings files. After the change in the device mappings file, cople of tries failed but then in the 3rd try Robots, Drives and Storage units were configured. We performed the inventory and every thing looked fine.
Couple days later we had to run an inventory and when we clicked Robot > Inventory Robot from Java Console, the window appeared only with the master server name in it and without any robots showing in the window. We tried Netbackup Administration Console and tried the inventory, it did show both the robots and was able to run the inventory.
During the troubleshooting we have updated the Device Mapping file to latest version 1.23. Checked all media servers for consistency.
This issue has been going on for almost 3 weeks and Symantec has not yet able to resolve it.
Any help will be appreciated.
Other symptoms:
1. Robot Diagnostics fails for 1 library (all 4 steps).
2. Robtest from the media servers controlling the library is successful.
3. Scan -changer shows the robot
4. Scan for a drive via Wizard configures the drive as standalone.
5. PC running Java Console is out of equation, issue is persistent from any PC.
Symantec has finally resolved the issue. The device mapping file was not renamed properly when it was replaced last time. Renaming the file fixed the issue.
