Instructions

CAS behavior for cross bucket access under same namespace is not supported in ECS-CAS. Centera supports this type of behavior. This is known limitation in ECS-CAS implementation, and it comes from the architectural differences between Centera and ECS.
 
Description:
There are two CAS buckets under one namespace TEST.
dc_bucket
dr_bucket
 
There are two object users to have these buckets as default CAS bucket.
dc_profile has dc_bucket as default CAS bucket
dr_profile has dr_bucket as default CAS bucket
 
The below ACLs were configured.
dc_bucket: dc_profile -> Full, dr_profile -> Read and Read ACL
dr_bucket: dc_profile -> Read and Read ACL, dr_profile -> Full
 
After writing one object to ECS using dc_profile PEA, this clip can be accessed using dc_profile. However, clip cannot be accessed using dr_profile and see that this Error message was -10021 (CLIP_NOT_FOUND).
