IVM.DLL
This component is used by the Logical Volume Manager.
IVM.DLL is a renamed version of IBM's LVM.DLL that was included on eComStation.
eComStation included a new LVM.DLL that forwards some of it's functions to IVM.DLL. It was reported that the newer "LVM.DLL forwarder" bypasses a couple of checks so that Bootable JFS and Air-BOOT can work seamlessly.
The newer "LVM.DLL forwarder" intercepts some functions like:
- The Start_Logging and Stop_Logging functions to enable merging its own log data with the LVM log (when LVM logging is turned on).
- It also wraps Open_LVM_Engine to save copies of any Windows NT disk signatures from the MBR, and wraps Commit_Changes to restore them back (except when an explicit newmbr operation was performed).
- It wraps Get_Volume_Information to always report compatibility volumes as Bootable if Air-Boot is installed.
- And similarly wraps Get_Valid_Options to report than a compatibility volume can be set as Installable if Air-Boot is installed.
Tip: Set the environment variable LVM_LOGWRAPPER=1, then run LVM with the /startlog parameter, the wrapper's own log will get added to the log generated by LVM.
