Yes, you can do takover/giveback to activate pending changes. It should be non-disruptive for FC connections, assuming proper multipathing setup. CIFS is generally disruptive, although in practice impact may be low (if nobody is using mapped drive, nothing evil happens).

Serial number is associated with controller (motherboard) and systemid is associated with NVRAM. It is in principle possible to replace these parts or exchange them between controllers. So at least in case of hardware replacement due to component fault these numbers may change. You will need to updated them in your system.

Do you have FC ports or CNA ports? Please show output of "system node hardware unified-connect show".

Good. Congratulations!

How did you reinitialize controllers? You need to remove ownership from all disks (and current partitions) before starting it.

aborzenkov · ‎2016-11-28

As far as I know root-data-data is used only for SSD disks.

Autoboot is already set to true, but apparently default image was not set to new version. This is usually indication of not perorming clean shutdown during update. I would suggest doing update once more and carefully following procedure in this case, in particular, make sure to perform clean shutdown or takeover after installing new version.

Open case with NetApp support - boot device replacement is required.

The obvious impact is, if your SAS controller fails, you lose access to disks. Using two independ controllers to connect disks improves resiliency.

Are you sure you have not misunderstood the question? If you have not, please point to the place in documentation which describes negotiated switchover due to all LIF ports down. So far documentation states the following reasons for AUSO: Node power down, Node power loss, Node panic, Node reboot. Nothing about network whatsoever.

Not to my best knowledge, it is not possible. Did you consider using SSD as ZFS cache devices?

Data ONTAP has always been vendor agnostic - the same NetApp drive part number usually is provided by several different vendors.

aborzenkov · ‎2016-11-16

You forgot to say what Data ONTAP version you are using. In 7G local users are managed by useradmin command; I do not remember earlier versions.

@Overz wrote: And i cannot choose a new LIF type for these 2 connections either? No. It has to be node management for node management and intercluster LIF for intercluster traffic.

@Overz wrote: choose a failover policy wich will failover to a other head You can't. Those LIF types cannot failover to another node.

aborzenkov · ‎2016-11-15

@Overz wrote: So if one port goes down, the other [filer] should already automatically take over right? This depends on failover policy. Some LIF types never failover to another node. This includes node management and intercluster LIFs.

aborzenkov · ‎2016-11-15

@Overz wrote: So if as in the message stated the "home port or home node" would go offline, a failover is not possible right? No. The message simply tells you that those LIFs do not have redundant ports, so if connection to the single port fails, those LIFs are not accessible. For intercluster LIF you should actually consider adding redundant port, because if your only port fails, no snapmirror traffic from/to this node is possible. Having redundant ports for node management does not hurt as well.

Are you able to NetBoot other controller using the same HTTP server? Are you able to NetBoot other Data ONTAP version on this controller (e.g. 7.3.5)?

aborzenkov · ‎2016-11-14

What exactly "not accessible" means? Paste exact command and its output (error message) that demonstrates it.

aborzenkov · ‎2016-11-12

cDOT does not support OSSV and you cannot use cDOT as disaster recovery partner for 7-Mode (well, you probably can, but just once). Reinstall is simple, but you need cluster license for this.

So 1.0.23 is used as spare for both root and data partitions. 1.0.22 has one spare partition (root). Both partitions are independent, so one can be used as part of aggregate and another can be used as spare. Did you try to read documentation about ADP and disk pools and do you have specific question about documentation content?

aborzenkov · ‎2016-11-09

Paste output of "storage aggregate show-spare-disks"

aborzenkov · ‎2016-11-09

1. Shared is partitioned disk. Look in documentation for ADP (Advanced Disk Partition). In summary - disk is divided in two partitions and each partition can be used independently as part of aggregate (or pool, but that's another story). 2. Yes, each partition can be part of separate aggregate. 3. Not really. For SSD disks in FlashPool you can split disks in 4 partitions, but they are added to disk pools, not disk aggregates. 4. Yes. Disk should be automatically partitioned as needed when used for disk replacement.

aborzenkov · ‎2016-11-08

Yes, it is possible. There is no data loss, the same LUN can be accessed concurrently using FC, iSCSI and FCoE. You need iSCSI license. How to setup iSCSI is described pretty extensively in manuals, just check manuals for your version.
