Information

 
TitleUnable to disable system-mode maintenance - "Operation failed as cluster is in transient state"
Symptoms
  • Operation failed as cluster is in transient state when issuing command no system-mode maintenance
Environment
  • NOS 7.0.0
Cause
In 7.0.0, this command system-mode maintenance was introduced.
The command enables maintenance mode for graceful traffic diversion from the switch by shutting down edge ports and increasing the cost of ISLs
If the procedure is not correctly followed attempt to disable maintenance mode (no system-mode maintenance) on the upgraded switch may fail with "Operation failed as cluster is in transient state" error.
Resolution
This is a known Defect. Upgrade to NOS 7.2.0

Below is a use case example of system-mode maintenance for firmware upgrade in a 2 switch cluster.
=====
1. Enable maintenance-mode on non-principal RB2
2. Perform shutdown on all ISLs between the two rbridges
3. Confirm all data traffic is forwarding only on RB1
4. Perform firmware coldboot upgrade on RB2
5. Confirm firmware upgrade is successful on RB2
6. Disable maintenance-mode on RB2
7. Enable maintenance-mode on RB1
8. Confirm all data traffic is forwarding only on RB2
9. Perform firmware coldboot upgrade on RB1
10. Confirm firmware upgrade is successful on RB1
11. Disable maintenance-mode on RB1
12. Perform no shutdown on all ISLs between the two rbridges
13. Confirm RB1 and RB2 rejoins VCS successfully with new firmware version and maintenance-mode disabled on both nodes.
