Once you have uninstalled the HADB server, delete the directories that store communication-information files.

Organization of this subsection

(1) Executing the command for deleting the directories that store communication-information files
(2) Checking that the directories for storing communication-information files have been deleted

(1) Executing the command for deleting the directories that store communication-information files

The communication-information file directories to be deleted differ depending on the OS version of the server machine.

If the server machine's OS is Red Hat Enterprise Linux Server 6 (64-bit x86_64)

See (a) Red Hat Enterprise Linux Server 6.
If the server machine's OS is Red Hat Enterprise Linux Server 7 (64-bit x86_64)

See (b) Red Hat Enterprise Linux Server 7.

(a) Red Hat Enterprise Linux Server 6

Delete the following directories:

/dev/HADB/pth
/lib/udev/devices/HADB/pth

Delete the /dev/HADB/pth directory.

As a superuser, enter the following operating system command, and then press the Enter key. The /dev/HADB/pth directory is deleted.
```
rm -rf /dev/HADB/pth
```
Delete the /lib/udev/devices/HADB/pth directory.

As a superuser, enter the following operating system command, and then press the Enter key. The /lib/udev/devices/HADB/pth directory is deleted.
```
rm -rf /lib/udev/devices/HADB/pth
```

(b) Red Hat Enterprise Linux Server 7

Delete the following directory and file:

/dev/HADB/pth
/etc/tmpfiles.d/dev-HADB-pth.conf

Delete the /dev/HADB/pth directory.

As a superuser, enter the following operating system command, and then press the Enter key. The /dev/HADB/pth directory is deleted.
```
rm -rf /dev/HADB/pth
```
Delete the /etc/tmpfiles.d/dev-HADB-pth.conf file.

As a superuser, enter the following operating system command, and then press the Enter key. The /etc/tmpfiles.d/dev-HADB-pth.conf file is deleted.
```
rm -f /etc/tmpfiles.d/dev-HADB-pth.conf
```

(2) Checking that the directories for storing communication-information files have been deleted

Check that the directories for storing communication-information files have been deleted correctly.

The items to be checked differ depending on the OS version of the server machine.

If the server machine's OS is Red Hat Enterprise Linux Server 6 (64-bit x86_64)

See (a) Red Hat Enterprise Linux Server 6.
If the server machine's OS is Red Hat Enterprise Linux Server 7 (64-bit x86_64)

See (b) Red Hat Enterprise Linux Server 7.

(a) Red Hat Enterprise Linux Server 6

Check whether the /dev/HADB/pth directory has been deleted.

As a superuser, enter the following operating system command, and then press Enter:
```
ls -d -l /dev/HADB/pth
```
From the execution result of the ls command, you can check whether the /dev/HADB/pth directory has been deleted. The following shows an example of the execution result.

▪ Execution result example
```
ls: cannot access /dev/HADB/pth: No such file or directory
```
If the execution result such as the preceding one is displayed, the /dev/HADB/pth directory has been deleted.
Check whether the /lib/udev/devices/HADB/pth directory has been deleted.

As a superuser, enter the following operating system command, and then press Enter:
```
ls -d -l /lib/udev/devices/HADB/pth
```
From the execution result of the ls command, you can check whether the /lib/udev/devices/HADB/pth directory has been deleted. The following shows an example of the execution result.

▪ Execution result example
```
ls: cannot access /lib/udev/devices/HADB/pth: No such file or directory
```
If the execution result such as the preceding one is displayed, the /lib/udev/devices/HADB/pth directory has been deleted.

(b) Red Hat Enterprise Linux Server 7

Check whether the /dev/HADB/pth directory has been deleted.

As a superuser, enter the following operating system command, and then press Enter:
```
ls -d -l /dev/HADB/pth
```
From the execution result of the ls command, you can check whether the /dev/HADB/pth directory has been deleted. The following shows an example of the execution result.

If the execution result such as the preceding one is displayed, the /dev/HADB/pth directory has been deleted.
Check whether the /etc/tmpfiles.d/dev-HADB-pth.conf file has been deleted.

As a superuser, enter the following operating system command, and then press Enter:
```
ls -l /etc/tmpfiles.d/dev-HADB-pth.conf
```
From the execution result of the ls command, you can check whether the /etc/tmpfiles.d/dev-HADB-pth.conf file has been deleted. The following shows an example of the execution result.

▪ Execution result example
```
ls: cannot access /etc/tmpfiles.d/dev-HADB-pth.conf: No such file or directory
