El siguiente problema es con el archivo config.yaml: el terminal debe apuntar a la gateway de mensajería instantánea a través de "https:", no de "http":

config.yaml:

username: "K8S_user"
password: "password"
systemID: "55b832655862adb7"
endpoint: "http://10.10.10.19:28443" <<<
skipCertificateValidation: true
isDefault: true
mdm: "10.10.10.20,10.10.10.21,10.10.10.22"

 

Se debe cambiar la contraseña del usuario.

Después de iniciar sesión a través de SCLI y cambiar la contraseña, la implementación continuará:

# scli --login --username K8S_user --password password
Logged in. User role is Administrator. System ID is 55b832655862adb7
Current password must be changed. Please use --set_password command

# scli --set_password --old_password password --new_password newpassword

# scli --login --username K8S_user --password newpassword

La configuración de SDC (/etc/emc/scaleio/drv_cfg.txt) contiene varias entradas incorrectas del sistema (MDM-ID) - "0000000000000000”. Eliminación de ID de sistema incorrectos con "drv_cfg" corrige el problema.
