Scenarios

After the SFS file system is created, attach it to the SAP HANA and SAP Business One node to provide the backup volume for SAP HANA. This section describes how to attach the SFS file system to a cloud server.

Prerequisites

You have created a file system and have obtained the shared path of the file system.
The IP addresses of the DNS server used to resolve the file system domain name have been configured on the cloud servers.

Procedure

Use PuTTY to log in to the NAT server with an EIP bound. Ensure that user root and the key file (.ppk file) are used for authentication. Then, use SSH to switch to the SAP HANA and SAP Business One nodes.
Run the following command to check whether the NFS software package has been installed:

rpm -qa|grep nfs

Information similar to the following is displayed:
```
nfsidmap
nfs-client
```
- If yes, go to 3.
- If no, run the zypper install nfs-client command to install the package.
Run the following command to check whether the domain name in the file system shared path can be resolved:

nslookup File system domain name
Run the following command to create a local path for attaching the file system:

mkdir Local path

For example: mkdir /hana/backup
Run the following command to attach the file system to the SAP Business One node:

mount -t nfs Shared path Local path
Run the following command to view the attached file system:

mount -l
Write the disk attaching information to the /etc/fstab file so that disks can be automatically attached when the cloud server is restarted.

vi /etc/fstab
Enter the path information.

Enter the path based on the actual condition.
NOTE:
- The /etc/fstab format is Disk ID or partition Attached directory Disk format defaults 0 0.
- In the preceding format, the recommended value of the last field is 0. In this case, the disk can be attached to the other instance if required.
For example,
```
Shared path   /hana/backup              nfs    defaults 0 0
```
Save the changes and exit.
