Reset Machine Down Recovery Fail

Overview

If two CMs in the storage system fail simultaneously, all port paths are closed in order to protect unwritten data. This condition is called "Machine Down" status.

Normally, the storage system runs a recovery process when the Machine Down status is detected to restore normal operation. However, if the recovery process fails, the storage system's power supply cannot be turned off to prevent the loss of unwritten data. This function is used to resolve this status and restore the storage system.

Caution

  • This function can only be used when the status of storage system is "Not Ready 15" (machine down recovery failed) or when the maintenance of the failed CM has been completed.
