RFIssuState

• Base type Enumeration

ISSU state represents the current system state. unset - unset state; if the system is booted from tftp or from ROMMON such that the image is not the first in BOOT init - init state; the first ISSU state that the system will move to after the unset state, when the ISSU process has just been kicked off. The first CLI that is executed to make this happen is the loadversion CLI. loadVersion - Once the loadversion CLI has been executed, the state of the system is changed to reflect this, and this state is called the loadVersion state. The boot variable on the Standby is updated to point to the new image that the Standby needs to load and then it is reset. runVersion - runVersion state; When the system is in the loadversion state, the Active is running the old image and the Standby is running the new image. When the runversion CLI is executed, a switchover occurs, and the Standby running the new image takes over as the Active. The state of the system at this stage is updated to runversion. commitVersion - in the runversion state, the Active is running the new image, and the Standby is running the old image. When the user is satisfied with the functioning of the system, they execute the commitversion CLI, which will prepend the boot variable on the Standby with the new image, and then the Standby is reset. After this, the Standby comes up with the new image, and the state of the system is updated to reflect the commitVersion state.
