pre-mounting the destination NAS volumes in 9.6P2

Can anyone tell me the current instructions for NetApp Release 9.6P2

for pre-mounting the destination NAS volumes

 

Here are the older version instructions but the whole section for namespace is missing in 9.6p2 

 

 

Breaking SnapMirror relationships

If a SnapMirror source volume becomes unavailable and you want to access the data from the SnapMirror destination volume, you must break the SnapMirror relationship. Access to the destination volume is changed from data protection (DP) to read/write (RW).

Before you begin

  • The SnapMirror destination volume must be in the quiesced or idle state.
  • The destination volume must be premounted into the destination Vserver namespace.
  • Protocol access, such as CIFS, NFS, and iSCSI, must be configured on the destination Vserver to enable client access.

About this task

You can use the destination volume to serve data while you repair or replace the source, until you can reestablish the original SnapMirror relationship configuration.

SnapMirror relationships are listed and managed from the Vserver that contains the destination volume.

Steps

  1. From the home page, double-click the appropriate storage system.
  2. Expand the Vservers hierarchy in the left navigation pane.
  3. Select the Vserver that contains the destination volume, and then click Protection.

     

     

  4. Select the SnapMirror relationship that you want to break and verify that the Transfer Status column displays either Idle or Quiesced.
    If the relationship needs to be quiesced, click Operations > Quiesce.
  5. Click Operations > Break .
  6. Select the confirmation check box, and then click Break.

     

     

  7. Verify that the Relationship State column displays Broken Off.

     

     

  8. Redirect client applications to the destination volume.
    The procedures for redirecting clients vary depending on the configuration of your environment. See the Data ONTAP documentation for more information.

Result

The SnapMirror relationship is broken. The destination volume type changes from data protection (DP) read-only to read/write (RW). The system stores the base Snapshot copy for the data protection mirror relationship for later use.

After you finish

The best practice is to pre-mount the destination NAS volumes into the destination Vserver namespace as part of your disaster recovery configuration. If this was not done, you need to mount the volumes after breaking the SnapMirror relationship, to ensure that the volumes are accessible on the destination. You mount them into the namespace using the same junction path that the source volume was mounted to in the source Vserver. For details, see the task for mounting FlexVol volumes in the System Manager online Help.

Re: pre-mounting the destination NAS volumes in 9.6P2

I don't have the GUI instructions as I spend very little time using it.

 

If you are willing to drop to the CLI you can 'pre' mount the snapmirror'ed volumes after they finish their initialization step.

::> volume mount  -vserver  [vserver_name] -volume  [volume_name]  -junction-path [juntion_path_name]

 

Additionally you should make sure the export policy for the snapmirror'ed volume(s) is defined on the destination cluster for the proper subnets.

GUI instructions preferred... 

Re: pre-mounting the destination NAS volumes in 9.6P2

the mirrors are already setup... i created a nic for nfs but not sure how to get the namespace when that's no longer an option. 

Re: pre-mounting the destination NAS volumes in 9.6P2

Storage -> Junction Paths
Select  vserver from the 'SVM drop box.'
Click: Mount link.

A new window will appear;
Select the destination snapmirror volume from drop down.
Edit the Junction Name (if needed)
Change the Junction Path (if needed)

Click: Mount

 

Every SVM has a unique namespace. The SVM root volume is the entry point to the namespace hierarchy.

Re: pre-mounting the destination NAS volumes in 9.6P2

1.)  network interfaces -- added ip associated with nfs 

2.)  turned on NFS for the SVM

3.) added export policy to SVM for the IP address 

4.) added junction path to a specific volume

 

on attempting to add that new ip as a datastore -- fails. 

 

what am i missing? 

Re: pre-mounting the destination NAS volumes in 9.6P2

in junction paths the security style  is set to unix... how do i set that to ntfs? 

Re: pre-mounting the destination NAS volumes in 9.6P2

Got it... the trick was under SVM / Export Policies the client ip address was a subnet mask and not the ip address.  
But without the junction path it wouldn't have worked..

 

thank you
