Downloading and installing Dynamic Root Disk
For up-to-date detailed instructions about downloading and installing the DRD product, see https://
h20392.www2.hp.com/portal/swdepot/displayInstallInfo.do?productNumber=DynRootDisk.
NOTE: Due to system calls DRD depends on, DRD expects legacy Device Special Files (DSFs) to
be present and the legacy naming model to be enabled on HP-UX 11i v3 (11.31) servers. HP
recommends only partial migration to persistent DSFs be performed. For details of migration to
persistent DSFs, see theHP-UX 11i v3 Persistent DSF Migration Guide.
NOTE: On VxVM configurations, DRD expects OS Native Naming (osn) to be enabled. Enclosure
Based Naming (ebn) must be turned off.
