HA pairs and storage system model types

You can find more information about HA configurations supported by storage system models in the Lenovo Press.

  • Single-chassis HA pairs
  • HA configuration and the HA state PROM value
    Some controller modules and chassis automatically record in a PROM whether they are in an HA pair or stand-alone. This record is the HA state and must be the same on all components within the stand-alone system or HA pair. The HA state can be manually configured if necessary.
