[[Logical Volume Manager]] LVM DLL for OS/2
 
This library contains the [[Logical Volume Manager]] functions.
 
===Newer LVM.DLL Forwarder===
eComStation 2.x 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.
