I am very new to netapp world, sorry for the missing info. The takeover has been successful each time, but due to how frequently this is occuring. I like to validate the HA config first before I move on to other area to investigate the cause. Due to the environment I am not allow to use any tool to validate it, so is there any place i can check the config (any config file or System manager Network/HA config etc) to check and validate the setting ?
Again - if takeover was successful, HA configuration is OK (at least to extent you need it). Takeover does not happen because of HA problems - HA problems may cause failures in takeover, not takeover itself. You need to investigate why takeover happens.
