Abstract
A computer program product and corresponding computer-implemented method cause the performance of various operations to upgrade a network storage device having first and second storage controllers operating in an active-passive mode and disk media shared by the storage controllers. The first storage controller operating as a passive storage controller is caused to enter a new IQN for each virtual disk into a first iSCSI target configuration file and maintain a corresponding old IQN. The first storage controller is then caused to begin operating as the active storage controller so that the second storage controller, while operating as the passive storage controller, is caused to enter the new IQN for each virtual disk into a second iSCSI target configuration file and maintain the corresponding old IQN. Accordingly, the first and second iSCSI target configuration files map both the old and new IQNs to the virtual disks.
