Relocation of Intent Log

To relocate the Intent Log (bitmap file), please perform the following on all servers involved:

Note: LEAVE THE MIRROR IN THE MIRRORING STATE! Do not pause it and then move the bitmap file.

  1. If you have more than one DataKeeper mirror, move all mirrors to a single system so that it is source for all mirrors.

  2. On all systems, create the directory for the new location of the bitmap files ( i.e. R:\Bitmaps). Important: If you choose to relocate the bitmap file from the default location (%EXTMIRRBASE%\Bitmaps), you must first create the new directory before changing the location in the registry and rebooting the system.
  3. Modify the BitmapBaseDir registry value on all systems other than the mirror source system to reflect the new location. This includes mirror targets and any systems that share the volume with the mirror source or share with any of the targets.

    4. Edit Registry via regedit:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ExtMirr\Parameters

    Modify the "BitmapBaseDir" parameter, change to the new location ( i.e. R:\Bitmaps)

  1. Reboot each of the non-source systems. If this volume is part of a Windows cluster, be sure that you do not shut down too many nodes simultaneously or you may lose the cluster quorum and cause the cluster to shut down on the remaining nodes.

  2. Switch any volumes on the source system over to another system (target or shared source). Repeat Steps 2 and 3 on the system that was previously source.
  3. After rebooting the original source system, all volume resources can be switched back to that system.
