Dynamic Storage Technology supports only OES Storage Services (NSS) volumes in shadow volume pairs. You must install OES Storage Services and any other OES Services that it requires. For information, see Installing and Configuring OES Storage Services
in the OES 2023: NSS File System Administration Guide for Linux.
IMPORTANT:Some NSS file system features require special handling when using NSS volumes in a DST shadow volume pair. For information, see Section 9.4, Using NSS Volumes in DST Shadow Volume Pairs.
