Question: Standalone Director crashes and backup is lost
Answer:
Note: You would need the backup files saved externally to restore crashed Director. If only active configuration is lost, move to step 3b
1) Build a new Director (on VM or Bare-metal) with exact same release that backup was created/saved from.
2) Follow Director initial setup steps. (VD-SETUP)
a) Execute "/opt/versa/vnms/scripts/vnms-startup.sh".
b) Add a static route for 10.0.0.0/8 (or the subnet using for SD-WAN overlay).
3) Restore the Director backup file.
a) Copy the backup file in following location on new Director --> /var/versa/backup/
b) Use "request system recovery list" to see the files.
c) Execute "request system recovery restore file <backup-file>" to restore the Director.
Question: Only one Director node fails in the HA (It can be Active or Standby)
Answer:
You can use active node to restore the new node. Follow below step as mentioned. Please take help from TAC team if required.
1) Disable HA on Active node "request vnmsha actions disable-ha"
2) Follow steps 1 to 2 mentioned in "Question: Standalone Director crashes and backup is lost" to setup new Director.
3) Now enable the HA on Active node only (HA SETUP LINK) and add new node as Standby. It will sync from Active.
IMPORTANT Note: Make sure to enter Active node IP address as Master and Designated Master, else sync may happen from new node to Active node and wipe all config.
