Access to Net-Storage (storage access via NFS) is possible for BS2000 systems (for Native BS2000 and the BS2000 VMs) of the SU /390 provided the prerequisites are fulfilled in the HNC.
For administrative access to the Net-Storage server that provides the Net-Storage, the administrator of the Net-Storage server must create an account that is the owner of the directory released via NFS. In the case of Eternus-CS HE NAS, the account must be the owner of the file group of the NAS share. The user ID and group ID must be obtained from the administrator of the Net-Storage server.
The NFSv4 domain must correspond to the domain name set on the Net-Storage server.
The HNC always tries to connect to the Net-Storage via NFSv4. If the mounting via NFSv4 fails, NFSv3 is used as protocol.Each Net-Storage connection must be configured in the network.
You configure Net-Storage in the HNC using the Management menu, Net-Storage tab.
> | Select Hardware -> Units ->
|
The Net-Storage tab displays the Net-Storage permissions, Net-Storage client, Net-Storage connection properties, and Net-Storage connection addresses groups.
The following functions are available to you:
Changing access right for the HNC
In the Net-Storage permissions group, the current user and group ID that can be used to administrate the Net-Storage access are specified in the form of userid/groupid. The IDs must be obtained from the system administrator of the Net-Storage server. The default value for both is 0.
> | In the Net-Storage permissions group click the Change icon by Access authorization - User ID or Group ID. In the subsequent dialog box change the user and/or group ID and confirm the action. |
If the default value is not changed, the access is attempted with root rights, which is not recommended for reasons of data protection.
Please note that as a result of this action, all mounted Net-Storage devices in the BS2000 will be unmounted. You will therefore have to re-mount them afterwards.
Entering or changing configuration data for the NFSv4 domain
> | In the Net-Storage permissions group, click on the Change icon by NFSv4 domain and enter the domain name in the subsequent dialog. Confirm the action. |
Please note that as a result of this action, all mounted Net-Storage devices in the BS2000 will be unmounted. You will therefore have to re-mount them afterwards.
Restarting the Net-Storage client
The Net-Storage client group displays the current status of the Net-Storage client and the mounted directories.
> | In the Net-Storage client group, click on Restart Net-Storage client and confirm the action. |
Please note that as a result of this action, all mounted Net-Storage devices in the BS2000 will be unmounted. You will therefore have to re-mount them afterwards.
Adding and changing a Net-Storage connection to the HNC
> | In the Net-Storage connection properties group click Add connection. Make the required entries in the subsequent dialog box and confirm the action. |
> | In the Net-Storage connection properties group click the Change icon by the required Net Storage connection and enter your changes in the subsequent dialog. Confirm the action. |
For further information, see the "Description Paper Net-Storage Guide" [15].
Deleting a Net-Storage connection
> | In the Net-Storage connection properties group click the Delete icon by the required Net-Storage connection and confirm the action. |
Adding a Net-Storage connection address (HNC)
> | In the Net-Storage connection addresses group click Add IP address. Make the required entries in the subsequent dialog box and confirm the action. |
Deleting a Net-Storage connection address
> | In the Net-Storage connection addresses group click the Delete icon by the required Net-Storage connection and confirm the action. |
