When attempting to install the Managed Device agent using a packaged installer on HP-UX the following error is received:
vxfs mount: mount option(s) incompatible with file system /dev/...
This is caused by a bug in InstallAnywhere which is used to package the installer where it tries to mount a file system that's already mounted.
Install the package manually from the command line using:
/usr/sbin/swinstall -x mount_all_filesystems=false -s /path_to_your_depot_file/managesoft-8.5.0.depot managesoft
