Startup commands for your storage system are stored in the /etc/rc file. The /etc/rc file contains commands that the storage system executes at boot time to configure the system.
Startup commands are placed into the /etc/rc file automatically after you run the setup command or the Setup Wizard.
Some commands cannot be stored in the /etc/rc file. This includes commands that are executed by subsystems that are not yet available when the /etc/rc file is executed. For example, you cannot include iscsi commands in the /etc/rc file. Doing so prevents your storage system from booting successfully.
