NetApp vFiler DR mit Data ONTAP Simulator Teil 6: vFiler erstellen und vFiler DR konfigurieren
Dies ist Teil einer Artikelserie.
Hinweis: In diesem Artikel wird vFiler DR mit asynchroner Replikation eingerichtet. Wenn synchrone Replikation gewünscht ist, bitte in diesem Teil nur den vFiler erstellen und dann mit Teil 7 fortsetzen. Den Abschnitt “vFiler DR konfigurieren” aus diesem Artikel überspringen.
Jetzt wird endlich der eigentliche vFiler auf dem ersten Simulator (netapp01) angelegt. Entweder per OnCommand System Manager
oder über SSH.

Netmask to use: [255.255.255.0]: 255.255.255.0
The administration host is given root access to the filer's
/etc files for system administration. To allow /etc root access
to all NFS clients enter RETURN below.
Please enter the name or IP address of the administration host:
Do you want to run DNS resolver? [n]: y
Please enter DNS domain name []: test.local
You may enter up to 3 nameservers
Please enter the IP address for first nameserver []: 192.168.2.50
Do you want another nameserver? [n]: n

Default password for root on vfiler vfiler01 is "".
New password:Tue Jan 17 00:21:51 CET [vfiler01@netapp01:useradmin.added.deleted:info]: The user 'root' has been added.
Retype new password:
Tue Jan 17 00:22:05 CET [vfiler01@netapp01:passwd.changed:info]: passwd for user 'root' changed.
Do you want to setup CIFS? [y]: y
This process will enable CIFS access to the filer from a Windows(R) system.
Use "?" for help at any prompt and Ctrl-C to exit without committing changes.
Your filer does not have WINS configured and is visible only to
clients on the same subnet.
Do you want to make the system visible via WINS? [n]: n
A filer can be configured for multiprotocol access, or as an NTFS-only
filer. Since multiple protocols are currently licensed on this filer,
we recommend that you configure this filer as a multiprotocol filer
(1) Multiprotocol filer
(2) NTFS-only filer
Selection (1-2)? [1]: 1
CIFS requires local /etc/passwd and /etc/group files and default files
will be created. The default passwd file contains entries for 'root',
'pcuser', and 'nobody'.
The default name for this CIFS server is 'VFILER01'.
Would you like to change this name? [n]: n
Data ONTAP CIFS services support four styles of user authentication.
Choose the one from the list below that best suits your situation.
(1) Active Directory domain authentication (Active Directory domains only)
(2) Windows NT 4 domain authentication (Windows NT or Active Directory domains)
(3) Windows Workgroup authentication using the filer's local user accounts
(4) /etc/passwd and/or NIS/LDAP authentication
Selection (1-4)? [1]: 3
What is the name of the Workgroup? [WORKGROUP]: WORKGROUP
CIFS - Starting SMB protocol...
It is recommended that you create the local administrator account
(VFILER01\administrator) for this filer.
Do you want to create the VFILER01\administrator account? [y]: y
Enter the new password for VFILER01\administrator:
Retype the password:

Starting snapmirror initialize commands. It
could take a very long time when the source or
destination filers are involved in many
simultaneous transfers. The console will not be
available until all initialize commands are
started successfully. Please use the
"snapmirror status" command on the source
filer to monitor the progress.
Volume 'vol_vfiler01' is now restricted.
Upon activation, do you want the DR vfiler to use a different
set of DNS servers from the production vfiler? [n]: n

Dabei handelt es sich um einen asynchronen SnapMirror. Das bedeutet die Daten werden auf den ersten Simulator geschrieben und landen mit einem leichten zeitlichen Versatz auf dem zweiten Simulator. Standardmäßig findet die Replizierung alle 3 Minuten statt. Mit einem snapmirror status kann man sich den aktuellen Zustand anzeigen lassen. Dabei sieht man das die Zeit in der Spalte “Lag” bis zu 3 Minuten beträgt und danach die Replizierung startet.
