Alletra-9000 Remote Copy with Peer Persistence Synchronous Replication

[chad-jones]

I followed this guide Remote Copy with Peer Persistence Synchronous Replication Parameters to create a replication enabled StorageClass. Creating a PVC with this StorageClass results in error. It seems from the Alletra event log that invalid syntax for creatercopygroup is sent from the csi driver.

Thanks for reporting this. It would be best if you file a support case with HPE to get this resolved.

The response from HPE Support:

The issue is the CSI Driver is expecting remote array name showsys -d and the target name defined in showrcopy -d targets to be exactly same.
