This will scan the `172.16.0.0` subnet returning the host and port that return a response and store the results in a local cache with at the `data/assets.db` path. Additional flags can be set such as `--host` to add more hosts to scan not included on the subnet, `--timeout` to set how long to wait for a response from the BMC node, or `--concurrency` to set the number of requests to make concurrently. Setting the `--format=json` will format the output in JSON. Try using `./magellan help scan` for a complete set of options this subcommand. Alternatively, the same scan can be started using CIDR notation and with additional hosts: This will scan the `172.16.0.0` subnet returning the host and port that return a response and store the results in a local cache with at the `data/assets.db` path. Additional flags can be set such as `--host` to add more hosts to scan that are not included on the subnet, `--timeout` to set how long to wait for a response from the BMC node, or `--concurrency` to set the number of requests to make concurrently with goroutines. Try using `./magellan help scan` for a complete set of options this subcommand. Alternatively, the same scan can be started using CIDR notation and with additional hosts:
```bash ```bash
./magellan scan https://10.0.0.100:5000 --subnet 172.16.0.0/24 ./magellan scan https://10.0.0.100:5000 --subnet 172.16.0.0/24
``` ```
Check the help for each subcommand for more examples for specifying arguments. Once the scan is complete, inspect the cache to see a list of found hosts with the `list` command. Make sure to point to the same database used before if you set the `--cache` flag.
To inspect the cache, use the `list` command. Make sure to point to the same database used before:
```bash ```bash
./magellan list --cache data/assets.db --format json ./magellan list --cache data/assets.db
``` ```
This will print a list of node info found and stored from the scan. Like the `scan` subcommand, the output format can be set using the `--format` flag. This will print a list of host information needed for the `collect` step. Set the `ACCESS_TOKEN` if necessary and invoke `magellan` again with the `collect` subcommand to query the node BMCs stored in cache. If the `--host` flag is set, then an additional request will be made to send the output to the specified URL. The `--userame` and `--password` flags must be set if the BMC requires basic authentication.
Finally, set the `ACCESS_TOKEN`run the `collect` command to query the node from cache and send the info to be stored into SMD:

This uses the info stored in cache to request information about each BMC node if possible. Like with the scan, the time to wait for a response can be set with the `--timeout` flag as well. This command also requires the `--user` and `--pass` flags to be set if access the Redfish service requires basic authentication. Additionally, it may be necessary to set the `--host` and `--port` flags for `magellan` to find the SMD API (not the root API endpoint "/hsm/v2"). The output of the `collect` can be saved by using the `--output` This will initiate a crawler that will find as much inventory data as possible. The data can be viewed from standard output by setting the `--verbose` flag. This output can also be saved by using the `--output` flag and providing a path argument.
Note: If the `cache` flag is not set, `magellan` will use "/tmp/$USER/magellan.db" by default. Note: If the `cache` flag is not set, `magellan` will use `/tmp/$USER/magellan.db` by default.
