FusionManager is upgraded from V100R003C10SPC300 to V100R003C10SPC500 and then rolled back to V100R003C10SPC300. A user, then, expands the capacity of the FusionCube database (DB) node. However, the capacity expansion fails, and the information indicating failure in installing FusionStorage Agent is displayed in the log.
Then, we use PuTTY and the floating IP address to log in to the FusionManager node to check the /var/log/GalaxManager/irm/common/ irm_common.log
file generated when the failure occurs. The following information is displayed in the file.
