This file should only hold "requirements and constraints specified but not yet instantiated in the current configuration", i.e. information about domains that have not been bound yet. In reality, in current versions, it contains a bit more than that : vdsdev names and port range of vcc services, for instance (my understanding is that the "vdsdev" issue is getting fixed in LDoms 1.1). If you lose the file or it gets corrupted, those properties revert back to canonical values: your configuration still works but with canonical names. Also, you lose all information about unbound domains. > How do this complements or overrides the ldom config > stored in the SC? The ldom config stored in the SC is what's restored when your server is reset or powered off/on. The ldom-db.xml file complements it with the info it has (unbound domains's info) and does not overwrite it. A "strange" case is when you revert back to an old spconfig on the SC (ldm set-config), the ldom-db.xml file is not directly related to the config you will be in after your server reset. The algorithm still works because the file does not do any harm on the running configuration, it just restores the state of unbound domains. > > Thanks > Luis -- This message posted from opensolaris.org
