system clearLostData

Clears the Lost Data flag for all logical volumes.

SYNOPSIS

system ‑clearLostData 

   [{‑sessionKey | ‑u admin‑user ‑oracleFS oracle‑fs‑system}]
   [{‑outputformat | ‑o} { text | xml }]
   [{‑timeout timeout‑in‑seconds | ‑verify | ‑usage | ‑example | ‑help}] 

DESCRIPTION

The Lost Data flag, when set, indicates that conditions have occurred for which the Oracle FS System can no longer guarantee the integrity of the data and cannot guarantee that data loss has not occurred. The primary reason for a lost data condition is the occurrence of multiple hardware failures, multiple software failures, or both. Multiple failures can lead to the loss of data integrity guarantees. Most often, a lost data condition arises from hardware failures or from data loss in the flash-backed memory of a Controller.

For the volumes that are affected by the lost data condition, the system places the volumes offline and creates a system alert for each volume. Each volume that is affected remains offline until the lost data condition is cleared. If the Lost Data flag is set, any possible data loss has already happened. Delaying the clearing of the Lost Data flag does not provide any protective action.

When this condition exists, the user must perform one of the following actions to clear the Lost Data flag:
  • Acknowledge the possibility of lost data by running the system ‑clearLostData command. By clearing the Lost Data flag, you acknowledge that data loss might have occurred and that you have taken appropriate steps to verify the integrity of the volume data.
    Important! Validate the data integrity of the volume before allowing production operations to resume on the affected volume.
  • Delete the affected volumes.

Restarting the system does not clear the lost data condition.

Note: Only administrators with primary administrator, administrator 1, and administrator 2 roles are authorized to run the system ‑clearLostData command.
