When can you perform a rollback in VIAS?

A rollback in the context of VIAS (VPLEX Infrastructure Application Services) is a mechanism that allows you to revert to a previous state or configuration. This process is important during certain operations, particularly when there is the potential for unintended consequences that could negatively affect system performance or data integrity.

Performing a rollback during volume creation allows administrators to efficiently manage new volumes and their configurations. If any issues arise while creating a volume—such as configuration errors or failures—initiating a rollback at this stage helps restore the system to its previous operational state without impacting the rest of the system. This capability is particularly crucial as it minimizes downtime and helps maintain service continuity during the initial setup of volume resources.

In contrast, rolling back after a volume has been exposed to VPLEX, during system upgrades, or when a health check is failing does not allow for the same level of precaution. Once volumes are exposed or a system is upgraded, there may be dependencies or alterations that complicate a simple rollback. Thus, the most appropriate and logical time to implement a rollback is indeed during the volume creation process, where the configurations can be adjusted without further ramifications.
