We happen to debug the bug internally with our Firmware team and understood that this behavior is caused because of the Hard Drive state

When the IO's are started the Hard Drive was in Spun Down state , Hence IO's are failed with " Logical unit not ready, manual intervention required " for short while and then it recovered
