C.2.6 Drive character mapping file

If the replication destination volume is a Logical Unit (disk), the replication destination post-processing can assign a specific drive character or mount point to the partitions included in the Logical Unit (disk). To assign a drive character or mount point, perform the setting of the drive character or mount point in the replication destination post-processing.

The mount point assignment processing is performed as follows:

Check that the partitions included in the replication destination Logical Unit (disk) are in a state that allows drive character or mount point assignment.
The operating system recognizes the partitions included in the Logical Unit (disk) immediately after replication, and it takes a while before the state that allows assignment of drive characters or mount points is reached.
The systems checks whether the state that allows assignment is reached, then waits for a fixed time interval and checks again.
This check process is repeated until the state that allows assignment is reached.
Drive characters and mount points are assigned in accordance with the drive character mapping file.

Note

AdvancedCopy Manager does not assign drive characters or mount points in the following cases:
- There is no drive character mapping file.
- The section name of the volume at the targeted replication destination disk is not in the drive character mapping file.
Processing is stopped if there is something unsuitable (for example, if the drive character is currently in use, or if the directory specified as the mount point is incorrect) in the contents coded in the drive character mapping file.

File name and directory

Create a drive character mapping file on the server that contains the copy destination volume. Use the following filenames:

In the case of non-cluster operation

<Environment directory>\etc\repl\data\DRVMAP.INI

In the case of cluster operation

<Shared disk>:\etc\opt\swstorage\etc\repl\data\DRVMAP.INI

Example and description rules

The following is an example of a drive character mapping file:

[g1d1]
p1=D:
p2=C:\mnt
[g1d2]
p1=E:

An explanation of how to create a drive character mapping file is given below.

Create a section in the drive character mapping file for the targeted replication destination volume.
In this section, use the partition number of the targeted partition as the key, and specify the directory name that indicates the drive character or mount point to be assigned.

Note

Only one drive character or mount point can be specified for one partition.
The drive character or mount point assignment is cancelled if a partition does not have a specification.

Table C.7 DRVMAP.INI parameter settings
Key name	Explanation
p? (At "?", specify the partition number)	Specifies the assigned drive character or mount point directory name.
MountableCheckCount	Specify the retry count to be used when the system checks whether the partitions in the replication destination Logical Unit (disk) are in the state that allows assignment of drive characters and mount points. A value from 1 to 10000 can be set. The default value is 120. Processing stops if the status still does not allow an assignment when the retry count is exceeded.
MountableCheckInterval	Specify the retry interval (in milliseconds) to be used when the system checks whether the partitions in the replication destination Logical Unit (disk) are in the state that allows assignment of drive characters and mount points. A value from 1 to 600000 (10 minutes) can be set. The default value is 500 (0.5 seconds).
