Thus, when the LDom resource goes online, the underlyingstorage will always be in read-write mode. When the LDom resource goes online,it sets the DR related parameters in the EEPROM parameternetwork-boot-arguments for the guest domain before starting the guest domain.When the guest domain boots, the vcs-network-reconfig service starts inside theguest domain. This service reads the EEPROM parameter and applies the disasterrecovery related parameters by modifying the appropriate files inside the guestdomain.
