This section explains the operation method for performing ETERNUS Disk storage system NAS operations with this product.
The functions that can be executed during operation are as follows:
The access method to the shared folder is the following:
Access Using CIFS Protocol
The shared folder is accessible by the Windows file sharing or network drive mapping.
Enter the following format to the address bar or to the network drive mapping window:
\\nasInterfaceIpAddress\sharedFolderName
When the shared folder is home directory, enter the following format.
\\nasInterfaceIpAddress\userName
When authenticating by Active Directory, the operation method varies depending on the presence of setup of an authentication server.
If Active Directory is configured as an authentication server:
Enter the user name and password registered to Active Directory.
When connecting from the client participating in Active Directory, authentication is not needed.
If an authentication server is not set up:
Enter the user name and password described in the ETERNUS Disk storage system manuals or local user name and password registered in the ETERNUS Disk storage system for connecting to NAS.
Information
Entering the IP address for NAS interface in the address bar can view sharable folders.
Access Using NFS Protocol
The shared folder is accessible by performing the NFS mount from a UNIX server using the following procedure:
When authenticating through LDAP, there is no difference in operation method with the presence of setup of an authentication server. Make the UNIX server participate in the LDAP domain to perform the NFS mount.
Check the NFS export path for the shared folder.
The NFS Export Path displayed in the Basic tab of the Detail Shared Folder screen is the shared folder path.
Refer to "Display Shared Folder" in the Web Console Guide for the procedure to display the Basic tab of the Detail Shared Folder screen.
Log in to the UNIX server with administrator privileges.
Execute the mount command to mount the shared folder.
When executing the mount command, specify the following:
For Solaris environments
mount -F nfs nasInterfaceIpAddress:nfsExportPath mountDestinationDir
For Linux environments
mount -t nfs nasInterfaceIpAddress:nfsExportPath mountDestinationDir
Information
Executing the showmount command on the UNIX server can view NFS mountable shared folders.
showmount -e nasInterfaceIpAddress
The format for the nfsExportPath is as follows.
/mnt/nas/nvnasVolumeNumber/data/sharedfolderName
After NFS mounted, logging in to the UNIX server as the user registered to LDAP can access the shared folder with the owner/group permissions set to the shared folder.
When not authenticating through LDAP, logging in to the UNIX server can access the shared folder.
The items of the shared folder can be changed. The items that can be changed are as follows:
Oplocks Configuration (when the protocol is CIFS or both CIFS and NFS)
Data Access SMB Encryption (when the protocol is CIFS or both CIFS and NFS)
Enumeration Based on Access Permission Settings (when the protocol is CIFS or both CIFS and NFS)
Writing Authority
Note
When the configuration of a shared folder is changed, sharing is temporarily suspended and it is not possible to access the shared folder. When the changes to the shared folder are complete, sharing is automatically resumed.
When data access encryption is enabled, clients that do not support SMB 3.0 cannot access the shared folder.
When accessing the shared folder for which CIFS access permission is configured with CIFS protocol, priority is given to CIFS access permission settings, and the write permission settings are disabled.
For "homes" that is the shared folder for home directory, the settings in the following items cannot be changed:
Enumeration Based on Access Permission Settings
Writing Authority
See
Refer to "Change Shared Folder" in the Web Console Guide for information on how to make changes to the shared folder using Web Console.
The items of the shared folder can be changed. The items that can be changed are as follows:
Owner/Group of Shared Folder
Hosts Permitted Access
Hosts Denied Access (When the protocol is CIFS or both CIFS and NFS)
Hosts Allowed Access with root privilege (When the protocol is NFS or both CIFS and NFS)
User/Group Privileges that Permits CIFS Access
Note
When the shared folder settings have been changed, since the share is temporarily stopped, the shared folder gets inaccessible. When the change of the shared folder has been completed, the share is automatically resumed.
If CIFS access permission is configured, users/groups that are not permitted to access cannot access the shared folder with CIFS protocol. Also, if other access permission level is specified for a user and a group to which the user belongs, priority is given to "Read/Write".
When a user/group for which Read/Write permission is configured with CIFS access permission accesses the shared folder, even if "No" is set for write permission to shared folder, the shared folder is writable.
For "homes" that is the shared folder for home directory, the setting in the following item cannot be changed:
User/Group Privileges that Permits CIFS Access
When changing a host to which access is allowed with root privileges, change it according to the instruction listed in [Note] of "Host Access Configurations of Shared Folder" in "6.6.3.1 Creating Shared Folder".
See
Refer to "Change Shared Folder" in the Web Console Guide for information on how to make changes to the shared folder using Web Console.
The items of the NAS interface can be changed. The items that can be changed are as follows:
IP Address
RIP Setting
Port
Redundant port
Member ports of bonding port
Operating mode of bonding port
Information
Only when a new port is set to the NAS interface to which the port is not set, the setting of the port can be changed.
The following ports cannot be selected as the port:
Member ports of bonding port
The following ports cannot be selected for Redundant ports:
Port of same CM as assignment Allocation port
Redundant port of other port
Member ports of bonding port
The following ports cannot be selected as member ports of bonding port:
Port of CM different from the master port
Port to which a NAS interface has already been assigned
Duplicated port
Master ports of bonding port
It is not possible to delete all member ports and disable port bonding.
The NAS interface IP addresses allocated for the ports on which redundancy has been set cannot be changed.
With ETERNUS SF, the same operating mode and hash policy are set for the ports and Redundant ports. When a different operating mode is set for the Redundant ports using the ETERNUS Disk storage system CLI etc, the Redundant port side operating mode shall be set to the same setting as the port side operating mode when an ETERNUS SF NAS interface operation takes place.
See
Refer to "Change NAS Interface" in the Web Console Guide for information on how to change NAS interface using Web Console.
Note
When changing the settings of the Redundant port, access to the shared folder using the CIFS protocol shall become temporarily impossible.
Changes the name of the NAS Server. It is also possible to return it to the same setting as when the ETERNUS Disk storage system was shipped.
See
Refer to "Change NAS Server Name" in the Web Console Guide for the procedure for configuring from Web Console.
Note
When the Active Directory authentication Server is configured, delete the Active Directory authentication server before changing the name of the NAS Server. Refer to "Deleting Authentication Server" for how to delete the authentication server. Re-register the Active Directory Server, as well, after changing the NAS Server name.
Change the DNS Server settings. The change procedure and items that can be changed are the same as when configuring the DNS Server. Refer to "DNS Server".
The values of the authentication server can be changed.
The steps for making changes and the items that can be changed are the same as those when configuring the authentication server. Refer to "6.6.3.3 NAS File System Environment Settings".
Point
When changing the domain administrator name of the authentication server, it is necessary to re-enter the password of the domain administrator. When changing items other than the domain administrator name, the password of the domain administrator is not required.
The sharing status of the shared folder can be activated.
When sharing is activated, it is possible to access the shared folder via the NAS interface.
See
Refer to "Change NAS Interface" in the Web Console Guide for information on how to change NAS interface using Web Console.
The sharing status of the shared folder can be stopped.
When sharing is stopped, it is not possible to access the shared folder.
See
Refer to "Start/Stop Sharing" in the Web Console Guide for information on the procedure using Web Console.
Configures the backup of NAS volume data.
For the NAS backup configuration, apart from creating a NAS backup volume, a copy group and copy pair can be configured.
If NAS backup is not set up, this function is enabled to create a NAS volume backup system.
Configure the following for the NAS volume:
This is the volume for backup of the data of the NAS volume.
When there is no NAS backup volume, create a new NAS backup volume. Where there is a NAS backup volume, you can choose to either create a new NAS backup volume or use an existing NAS backup volume.
The NAS backup volume is created with the following details.
Volume Name | nasVolumeName$bak_N (*1) |
Capacity | Same as the source NAS volume |
Volume Type | Same as the source NAS volume |
Thin Provisioning Pool of the Creation Destination | User Selection |
*1: "N" is a sequential number from 0. The number of digits varies.
Point
For increased reliability, it is recommended to create Thin Provisioning Pools of the creation destination for the NAS backup volume and the NAS volume in separate Thin Provisioning Pools.
This is a group for defining copy pairs of a NAS volume and a NAS backup volume.
If no copy group definition for backup exists, a copy group is automatically created with the following settings:
Copy Group Name | NAS_QuickOPC_nasVolumeName_N (*1,*2) |
Copy Group Type | QuickOPC |
*1: "N" is a sequential number from 0. The number of digits varies.
*2: Characters other than those listed below in nasVolumeName are replaced with hash (#):
One-byte alphanumeric character, minus (-), underscore (_), hash (#), period (.), plus (+)
This is a copy pair of a source NAS volume and backup NAS volume.
It is created when creating a copy group.
See
Refer to "Set NAS Backup" in the Web Console Guide for information on how to configure steps using Web Console.
Point
When it is possible to execute this function from Web Console, the NAS backup configuration is not setup or is incomplete. When constructing a backup system of the NAS volume, implement this task.
When configuring NAS backup or backing up the NAS volume, an ETERNUS SF AdvancedCopy Manager Local Copy License is required.
Configures the NAS snapshot settings. Disabling NAS snapshot also uses this operation. The items that can be set are as follows:
Whether automatic snapshot is used
Number of snapshot generations
Schedule configuration (cycle, day, time)
RAID group on which NAS snapshot volume created (can only be set when newly set)
Note
When disabling the NAS snapshot settings, the snapshots already captured are discarded. The NAS snapshot volumes are also deleted.
When using the snapshot function, enable SNMP Trap Setup. If SNMP Trap Setup is not enabled, snapshot collection result is not notified. Refer to "Change ETERNUS Disk Storage System Information" in the Web Console Guide for the procedure to change SNMP Trap Setup via Web Console.
If snapshot settings for NAS volume is Manual mode, this operation cannot be executed. To set up/change/cancel Manual mode, refer to the ETERNUS Disk storage system manuals.
Point
When a new NAS snapshot is set, a NAS snapshot volume is automatically created on the specified RAID group.
The snapshot is collected based on the time set for the ETERNUS Disk storage system.
The RAID group on which the NAS snapshot volume is created cannot be modified while the NAS snapshot is in use. Reconfigure after disabling the NAS snapshot settings.
When a new NAS snapshot is configured, it automatically goes into start state.
See
Refer to "Set/Change/Release NAS Snapshot" in the Web Console Guide for the procedure for setting via Web Console.
The captured snapshot is referenced from the client in the following way.
Where the client server is a Windows environment
The captured snapshot can be referenced as the "previous version" using the Windows OS VSS feature.
Where the client server is a Linux or Solaris environment
The data in the shared folder when a snapshot was captured from ".snap" under the shared folder mounted on the client can be referenced. Each snapshot is in a directory named below:
Directory Name |
|
Point
Users can access the ".snap" directory. However, since ".snap" is a virtual directory, it is not displayed. The following is the example of a directory content displayed by the Is command:
|
It is possible to restore files and folders that have been modified/deleted due to operator error using the captured snapshot. The restore procedure is as follows:
Where the client server is a Windows environment
The snapshot to be restored can be specified and executed from "Restoring a previous version" using the Windows OS VSS feature.
Where the client server is a Linux or Solaris environment
There are directories for each snapshot in the ".snap" directory under the shared folder. Copy the files or directories you want to restore to the shared folder from the snapshots using the OS function.
Note
When data inconsistency is found in a snapshot, trace back the data through generations.
