CSNAPC-11774: SCC 6.2.2 AIX: sccCommandExecutor shell wrapper always returns exit code 0, ignoring pre/post-script return code
Issue
On AIX hosts, the SCC (SnapCenter Connector) CommandExecutor shell wrapper always returns exit code 0 to SnapCenter, regardless of the actual return code from the user-supplied pre or post script. This causes SnapCenter to continue and create snapshots even when a pre-script deliberately
fails, breaking the expected backup abort behavior.
