Windows System-Managed Encryption 3. Located in the highest level directory of the driver package, are non-debug versions of the tape and medium changer device drivers, ibmtpxxyyy.sys and ibmcgxxyyy.sys, where: v xx = ft for the filter driver, bs for the bus driver, or blank for the base driver, and v yyy = 2k for Windows 2000, or 2k3 for Windows Server 2003, or 2k8 for Windows Server 2008. Refer to Figure 32 on page 187. Note: The last driver level to include support for Windows 2000 is V6.1.4.8. Subsequent levels include support for Windows Server 2003 and Windows Server 2008 only, and only contain 2k3 files. 4. Copy the non-debug version of ibmtpxxyyy.sys or ibmcgxxyyy.sys to \winnt\system32\drivers, overwriting the version of the file already there. 5. Reboot the system. When the driver has started and commands are issued to it, the driver no longer produces debug output. Note: For Windows Server 2008 is necessary to Uninstall the devices and then Install the non-debug version of the driver. Reservation Conflict Logging When the device driver receives a reservation conflict during open or after the device has been opened it will log a reservation conflict in the Windows eventlog. Prior to logging the error the device driver will issue a Persistent Reserve In command to determine if a SCSI Persistent Reservation is active on the reserving host to get the reserving host initiator WWPN (World Wide Port Name). If successful, the device driver will log this information as follows: Reserving host key: kkkkkkkk WWPN: xxxxxxxx Where kkkkkkkk is the actual reserve key and xxxxxxxx is the reserving host initiator WWPN. After initially logging the reserving host WWPN, subsequent reservation conflicts from the same reserving host WWPN will not be logged to prevent multiple entries in the error log until either the reserving host WWPN is different than the one initially logged or the device driver has reserved the device and then another reservation conflict occurs. 188 IBM Tape Device Drivers Installation and User's Guide
