- Why I did it
Collecting MST dump before syncd restart on shutdown notification during a SAI failure
Dump can be found under:
root@sonic:/home/admin# ls -l /var/dump/mstdump/
total 10684
-rw-r--r-- 1 root root 5460332 Aug 15 18:41 mstdump_20220815_184143.tar.gz
-rw-r--r-- 1 root root 5473253 Aug 15 21:46 mstdump_20220815_214642.tar.gz
root@sonic:/home/admin# tar -xvzf /var/dump/mstdump/mstdump_20220815_214642.tar.gz

- How I did it
Checked for shutdown notification log in sairedis and used it to determine whether the shutdown is normal or due to SAI failure
- How to verify it
Simulated a SAI failure event and verified it. Verified it also on different reboots and config reload scenarios the dump is not generated
