Summary: Intelligent fibers are enabled or disabled at an optical port on the OptiX
OSN 1800 V100R001C01SPC100 (5.67.01.19) and the NE is upgraded to V100R002C00
SPC100 (5.67.02.13) or a later version. If intelligent fibers are reconfigured at the same
optical port and the SCC board is reset or backup databases are restored to the NE, the
SCC board cannot start up.
[Problem Description]
Trigger conditions:
Intelligent fibers are enabled or disabled at an optical port on the OptiX OSN 1800
V100R001C01SPC100 (5.67.01.19) and the NE is upgraded to V100R002C00 SPC100
(5.67.02.13) or a later version. If intelligent fibers are reconfigured at the same optical
port and the SCC board is reset or backup databases are restored to the NE, the SCC
board cannot start up.
For example, a user enables or disables intelligent fibers at an optical port on the OptiX
OSN 1800 V100R001C01SPC100 (5.67.01.19) and upgrades the NE to V100R002C00
SPC100 (5.67.02.13). Then, the user reconfigure intelligent fibers at the same optical
port. If the user resets the SCC board, the board cannot be started up.
Symptom:
The NE becomes unreachable from the NMS.
Identification method:
Check whether intelligent fibers are configured at an optical port of the OptiX OSN 1800
V100R001C01SPC100 (5.67.01.19), the NE is upgraded to V100R002C00 SPC100
(5.67.02.13) or a later version, intelligent fibers are reconfigured at the same port, and its
SCC board is reset, or backup databases are restored, which cause that the NE becomes
unreachable from the NMS.
[Root Cause]
When an OptiX OSN 1800 is upgraded from V100R001C01SPC100 (5.67.01.19) to
V100R002C00 SPC100 (5.67.02.13) or a later version, the SCC board cannot start up
due to intelligent fibers- related command changes and database index recreation
failure after the upgrade adaptation is complete.
[Impact and Risk]
Affected scope: in and out of China
Impact: The NE becomes unreachable from the NMS.
[Measures and Solutions]
Recovery measures:
Measure 1: Clear databases on the SCC board and reconfigure the services in the NE.
Measure 2: Send the backup databases before the fault occurs back to Huawei R&D
Department for restoration. Then, use the NMS to deliver restored data to the NE.
Workarounds:
Workaround 1: For the OptiX OSN 1800 V100R001C01SPC100 (5.67.01.19) with
intelligent fiber configurations, perform a warm reset on its SCC board after it is
upgraded to V100R002C00 SPC100 (5.67.02.13).
Workaround 2: Check OptiX OSN 1800 equipment on the live network using Smartkit
tools and rectify equipment with latent risks.
Preventive measures:
For the OptiX OSN 1800 V100R001C01SPC100 (5.67.01.19) with intelligent fiber
configurations and upgraded to V100R002C00 SPC100 (5.67.02.13) or a later version,
workaround 1 is recommended.
Database recovery failures are to be rectified in the OptiX OSN 1800 patch version.
You can directly upgrade the OptiX OSN 1800 V100R001C01SPC100 (5.67.01.19)
to a patch version.
Material handling after replacement:
Not involved.
[Rectification Scope and Time Requirements]
Not involved.
