従来のデータ保護を目的とした、クラスタ内/クラスタ間のミラーリング機能になります。
- クラスタ内 SnapMirror
- Cluster Network を使用して、ローカルクラスタ上で、SnapMirror を行う。
- ターゲットボリュームは、Source と同じ SVM でも、異なる SVM でも良い。
- クラスタ間 SnapMirror
- 異なるクラスタに存在するボリューム間で、SnapMirror を行う。
- クラスタ間の Intercluster LIF を使用する。

cluster2::> vserver setup
Welcome to the Vserver Setup Wizard, which will lead you through
the steps to create a virtual storage server that serves data to clients.
You can enter the following commands at any time:
"help" or "?" if you want to have a question clarified,
"back" if you want to change your answers to previous questions, and
"exit" if you want to quit the Vserver Setup Wizard. Any changes
you made before typing "exit" will be applied.
You can restart the Vserver Setup Wizard by typing "vserver setup". To accept a default
or omit a question, do not enter a value.
Vserver Setup wizard creates and configures only data Vservers.
If you want to create a Vserver with Infinite Volume use the vserver create command.
Step 1. Create a Vserver.
You can type "back", "exit", or "help" at any question.
Enter the Vserver name: bsvm-01
Choose the Vserver data protocols to be configured {nfs, cifs, fcp, iscsi, ndmp}: nfs, cifs, fcp, iscsi, ndmp
Choose the Vserver client services to be configured {ldap, nis, dns}: dns
Enter the Vserver's root volume aggregate [aggr1]: aggr1
Enter the Vserver language setting, or "help" to see all languages [C.UTF-8]: C
Enter the Vserver root volume's security style {mixed, ntfs, unix} [unix]: unix
Vserver creation might take some time to finish....
Vserver bsvm-01 with language set to C created. The permitted protocols are nfs,cifs,fcp,iscsi,ndmp.
Step 2: Create a data volume
You can type "back", "exit", or "help" at any question.
Do you want to create a data volume? {yes, no} [yes]: no
Step 3: Create a logical interface.
You can type "back", "exit", or "help" at any question.
Do you want to create a logical interface? {yes, no} [yes]: no
Step 4: Configure DNS (Domain Name Service).
You can type "back", "exit", or "help" at any question.
Do you want to configure DNS? {yes, no} [yes]: no
Error: Failed to create NFS. Reason: You do not have a valid license for "NFS". Reason: Package "NFS" is not licensed in the cluster.
Step 5: Configure NFS.
You can type "back", "exit", or "help" at any question.
Step 6: Configure CIFS.
You can type "back", "exit", or "help" at any question.
Do you want to configure CIFS? {yes, no} [yes]: no
Step 7: Configure iSCSI.
You can type "back", "exit", or "help" at any question.
Do you want to configure iSCSI? {yes, no} [yes]: no
Step 8: Configure FCP.
You can type "back", "exit", or "help" at any question.
Do you want to configure FCP? {yes, no} [yes]: no
