19.5.1 Data on the NNMi shared disk
This subsection lists the NNMi data files that are maintained on the shared disk when NNMi is running under HA.
The locations are mapped to the shared disk location as follows:
-
In Windows
- %NnmDataDir% maps to %HA_MOUNT_POINT%\NNM\dataDir
-
In Linux
- $NnmDataDir maps to $HA_MOUNT_POINT/NNM/dataDir
The following are the main directories that are moved to the shared disk:
-
In Windows
- %NnmDataDir%shared\nnm\databases\Postgres
Embedded database
- NnmDataDir%log\nnm
NNMi logging directory
- %NnmDataDir%shared\nnm\databases\custompoller
Custom poller collections export directory
- %NnmDataDir%nmsas\NNM\log
NNMi audit log directory
- %NnmDataDir%nmsas\NNM\conf
NNMi directory for configuring audit log files
- %NnmDataDir%nmsas\NNM\data
Transaction store used by ovjboss
-
In Linux
- $NnmDataDir/shared/nnm/databases/Postgres
Embedded database
- $NnmDataDir/log/nnm
NNMi logging directory
- $NnmDataDir/shared/nnm/databases/custompoller
Custom poller collections export directory
- $NnmDataDir/nmsas/NNM/log
NNMi audit log directory
- $NnmDataDir/nmsas/NNM/conf
NNMi directory for configuring audit log files
- $NnmDataDir/nmsas/NNM/data

The nnmhadisk.ovpl command copies these files between local disk and shared disk. Run this command as the instructions in this chapter indicate. For a summary of the command syntax, see the nnm-ha manpage.
However, for the following configuration files, NNMi in an HA configuration directly references the files copied to the shared disk.
Therefore, when changing these settings in NNMi with an HA configuration, first set it to maintenance mode, and then directly edit the files on the shared disk, instead of the files on the local disk.

In Windows
−%NnmDataDir%nmsas\NNM\server.properties
Use %HA_MOUNT_POINT%\NNM\dataDir\nmsas\NNM\server.properties in the HA cluster.
−%NnmDataDir%nmsas\nms\server.properties
Use %HA_MOUNT_POINT%\NNM\dataDir\nmsas\nms\server.properties in the HA cluster.
−%NnmDataDir%nmsas\NNM\conf\nms-auth-config.xml
Use %HA_MOUNT_POINT%\NNM\dataDir\nmsas\NNM\conf\nms-auth-config.xml in the HA cluster.
-
In Linux
−/var/opt/OV/nmsas/NNM/server.properties
Use $HA_MOUNT_POINT/NNM/dataDir/nmsas/NNM/server.properties in the HA cluster.
−/var/opt/OV/nmsas/nms/server.properties
Use $HA_MOUNT_POINT/NNM/dataDir/nmsas/nms/server.properties in the HA cluster.
−/var/opt/OV/nmsas/NNM/conf/nms-auth-config.xml
Use $HA_MOUNT_POINT/NNM/dataDir/nmsas/NNM/conf/nms-auth-config.xml in the HA cluster.
