…aidump_by_route_size (#2972) * * [saidump] • Saidump for DNX-SAI sonic-net/sonic-buildimage#13561 Solution and modification: To use the redis-db SAVE option to save the snapshot of DB each time and recover later, instead of looping through each entry in the table and saving it. (1) Updated sonic-buildimage/build_debian.sh, to install Python library rdbtools into the host. (2) Updated sonic-buildimage/src/sonic-sairedis/saidump/saidump.cpp, add a new option -r, which updates the rdbtools's output-JSON files' format. (3) Add a new script file: files/scripts/saidump.sh, to do the below steps For each ASIC0, such as ASIC0, edge-core#1. Save the Redis data. sudo sonic-db-cli -n asic$1 SAVE > /dev/null edge-core#2. Move dump files to /var/run/redisX/ docker exec database$1 sh -c "mv /var/lib/redis/dump.rdb /var/run/redis$1/" edge-core#3. Run rdb command to convert the dump files into JSON files sudo python /usr/local/bin/rdb --command json /var/run/redis$1/dump.rdb | sudo tee /var/run/redis$1/dump.json > /dev/null edge-core#4. Run saidump -r to update the JSON files' format as same as the saidump before. Then we can get the saidump result in standard output. docker exec syncd$1 sh -c "saidump -r /var/run/redis$1/dump.json" edge-core#5. clear sudo rm -f /var/run/redis$1/dump.rdb sudo rm -f /var/run/redis$1/dump.json (4) Update sonic-buildimage/src/sonic-utilities/scripts/generate_dump, replace saidump with saidump.sh * * [saidump] • Saidump for DNX-SAI sonic-net/sonic-buildimage#13561

What I did
Modify the reboot script not to use 'exec' when performing platform_reboot function call to avoid hang issue during reboot.
Like AS9726-32D/AS9736-64D, it will hang when capture kernel tried to stop sonic platform related service.
