This is part of the SMAPIv3 interface change from feature/REQ477/master, has to be merged together with these PRs: xapi-project/sm-cli#26 xapi-project/xapi-storage-script#56 xapi-project/xcp-idl#202 https://github.com/xapi-project/xen-api/pull/3433

The sharable flag is explained in the xcp-idl commit: https://github.com/xapi-project/xcp-idl/commit/c8bfaf9d61c547df42fac12f5d05b0165e24b83b

SMAPIv3: The activated on exception/redirection is explained here (SMAPIv3 can require snapshots to be taken on the host that has the VM running, instead of the master): https://github.com/xapi-project/xen-api/commit/620acd20e2753a7f10a970e6f1850b325fea082a SMAPIv2 uses a similar mechanism internally to redirect requests to the master (e.g. in case of storage migration).
