Making DRCT Volume Changes

CA VM:Director rewrites the volume allocation map on the object directory volume each time a directory is updated, caching information from that area.

To change anything affecting cylinder 0 of the volume, such as reallocating the volume using the CPFMTXA utility or relabeling the volume, perform the following steps:

1. Bring CA VM:Director down.
2. Perform the activity to change the allocation map or label of the volume.
3. To have CA VM:Director pick up the new allocation information, reinitialize CA VM:Director using the SOURCE operand.

Note: If you do not perform the tasks in this order, the new volume allocation or label information will be overlaid during the next CA VM:Director directory update.

If changing a volume label, change the DIRECT configuration file record in the PRODUCT CONFIG file and make appropriate DASD CONFIG changes. This may also require changes in other product configurations to indicate the new volume where the online directory resides.

Note: For more information about making changes to an online directory volume, see the following sections in this chapter:
