command has been sent.

• The check is passed => No further action is required.
• Pair Status remains to be Invalid => 4.

In the CLI, run showrmtarraylink -array array id -link link id to check whether Connection Status is Unconnected. array id and linkid can be obtained using the showrmtlink command.

• Yes => 2.
• No => 4.

• If the cable is removed => Insert the cable. After the cable is inserted, run the showrmtlink command in the CLI to check whether Connection Status is Connected. If no, replace the cable.
• If the cable is damaged => Replace the cable. After the cable is replaced, run the showrmtlink command in the CLI to check whether Connection Status is Connected. If no, go to step 3.
• If the cable connections are normal => 3.

• If the disk array is faulty => Rectify the fault. After the fault is rectified, run the showrmtlink command in the CLI to check whether Connection Status is Connected. If no, check whether the storage array is restarting.
• If the remote storage array is restarting, wait until the restart completes. After the restart is complete, run the showrmtlink command in the CLI to check whether Connection Status is Connected. If no, go to step 4.
• If the remote storage array status is normal => 4.

• Yes => 2.
• No => 3.
