Instructions

For a Unity Remote System added to PowerStore, when the SSL certificate expires and, or is renewed on the source, the existing SSL remote system certificate on PowerStore is not automatically refreshed. If the certificate is not refreshed on PowerStore, the management operations involving control connections to Unity fail for the block/file import sessions from that system. This prevents the user from proceeding with their data migration to PowerStore.

 

Customer Indication: File or Block import sessions fail with error showing inability to communicate with Unity Remote System due to expired certificate(s).

Unity certificate should be renewed on the PowerStore array using "svc_remote_system_certificate_operations" command. The command "svc_remote_system_certificate_operations" is introduced in PowerStoreOS 4.0 and documented in the PowerStore Service Scripts Guide. This command is not available in earlier versions of PowerStoreOS.

 

Note: This script must be run on the primary appliance in a multi-appliance cluster and on the node where the control path docker is running.

svc_remote_system_certificate_operations [-h] [-r]
