Wpływ

Wdrożenie RHOSP zostało wstrzymane i należy je ponowić, aby kontynuować.

Cause

Unknown

Resolution

Można użyć dowolnego z następujących obejść, aby rozwiązać stan wstrzymania:

  1. Ponów próbę.
  2. Wyłącz przenoszenie portów (w ramach zautomatyzowanego procesu) po zarejestrowaniu SDC/s w PowerFlex, uruchamiając poniższe polecenia.

Wyłącz wahanie portów dla określonego klienta SDC:

 scli --set_performance_parameters --sdc_id  --tech --sdc_port_flap_feature_enabled 0

Wyłącz przenoszenie portów dla wszystkich SDC:

 scli --set_performance_parameters --all_sdc --tech --sdc_port_flap_feature_enabled 0
