In-place conversion from 7-Mode to C-Mode is not supported. In 7-Mode both snapmirror and "vol copy" will preserve on-disk NTFS ACLs and all snapshots. You may need to adjust your CIFS shares confiuration to point to new volume though.   ... View more

Yes, it is normal. Disks normally have two paths and it does not matter which path is used to address it. Use "disk zero spares" to zero it. ... View more

According to https://kb.netapp.com/support/index?page=content&id=2018128&locale=en_US files must be created via CIFS to have sparse bit set. This is about 7-Mode though; it could be different in C-Mode. I suggest opening case with NetApp to clarify. If you get an answer, post here, it is interesting. ... View more

Yes, it is possible. The second step is not update of Data ONTAP - it is restoring of configuration on freshly reimaged boot media. You can skip it, but then some configuration will be reset to default (personally what I've encountered - autosupport configuration, ntp configuration, but there could potentially be more).   ...

First, I would strongly advise to install exactly the same version as is currently installed on old head. If you want to update - update current head first, install the same version on new head.   Look e.g. at document describing boot media replacement. In summary, you need to netboot the same version as you intend to install, stop at special boot menu, select 7 for "Install new software first", wait for two reboots, stop in special boot menu again and select 6 for "Update flash from backup config". Of course, second step is possible only after you connected and reassigned disks, because it restores configuration from root volume. ... View more

If you want cluster_mgmt LIF be on e0i interface, this interface should be connected to the 10.28.8.60/24 network (broadcast domain, VLAN, however it is called by your networking equipment). But my guess is that you simply need to create failover group for cluster_mgmt LIF that consists of e0M ports on all nodes.   Anyway right now you just need to move cluster_mgmt LIF to e0M port to get access again. ...

I doubt it directly relates to being MetroCluster; and failover can be relevant to the extent that your controller experiences increased load for a long time.

Default policy does not contain any rule, so access is denied by default. There no universal answer whether you should add rules to default policy or define your own - it all depends on your specific requirements. ... View more

@NEWNETAPP987 wrote:the network management manual it says that the cluster management IP cannot be on a vlan. No, it does not say it. It says that you cannot configure VLAN on port with cluster management role but this makes no sense - such role does not exist; this is most likely leftover from earlier versions. You can configure cluster management LIF on either data port or node management port. Usually it is configured on node management ports to cleanly separate management from data. ... View more

Do you ask about storage failover in HA pair or about "HA mode"? The former is of course enabled between partners in each HA pair. The latter can and need to be enabled on 2 node cluster (single HA pair) only. ... View more

SnapDriver also supports VMDK on datastore; and it definitely cannot resize datastore itself.   Note that VMFS cannot be reduced in size; so the only possibility to actually reduce space consumption is either use Storage vMotion to move data to new, smaller, datastore or enable thin provisioning and perform space reclamation. ...

Yes, you can setup SnapMirror to different volume on source system. ... View more

By the way, you can update both Data ONTAP and BIOS at once by running "software install <BIOS>" and "download -d" immediately after running "software install <DOT>". I had problems doing it (download failed) so I would recommend doing it in two steps - first install and download Data ONTAP, then check installed BIOS version with "version -b" and install and download BIOS separately if newer version is available. Bundled BIOS is installed into boot media by "software install <DOT>". Not really. "software install" only upacks archive. You you need to run "download" to actually install it on boot media. May be you mean "software update"? It does both in one step.   ... View more

When you are saying the latest common snapshot, are you referring to the last snaphost before SM relationship got broken off when I failover to DR site, which also means revert the volumes to the status as it was before failover?

Assuming you are speaking about SnapMirror - you can revert volume(s) to the latest common snapshot that was used as base for testing. But if you have production data, that's rather challenging exercise 🙂 ... View more
