Yes; I have partner account and cannot access this KB either.

if disk disk.auto_assign option is on then it means that no other steps nedded? No; all other steps are still required. to be more specific I have to add a new self with 24x 2TB disks, is it possible to add all the new disks on the existing aggregate? Yes, as long as total aggregate size will not exceed platform limits (check HWU).

aborzenkov · ‎2015-09-17

Before adding disks to aggregate you need to assign them to correct controller (disk assign). Depending on your configuration it may happen automatically and it may be wrong (see description of disk.auto_assign option).

The point is to free some space to allow you to increase root volume size.

You could try deleting some unneeded files (like logs) from system shell.

-Duration of the giveback : 53 seconds -Duration of the unavailability of network interfaces : 88 seconds. This is indication that switch ports, to which NetApp is connected, have spanning tree enabled.

There is single NVRAM battery inside FAS controller.

What filer model is it?

aborzenkov · ‎2015-09-11

NetApp redundancy is based on the assumption that takeover/giveback are transparent. If you have reasons to believe they are not, you have much larger problem and need to address it - it implies that one controller failure cannot be handled properly.

aborzenkov · ‎2015-09-10

Normally LACP across switches of different vendors is not possible, so takeover/giveback is the only way. It should be transparent if everything is configured correctly. But please note that there is always possibility of misconfiguration when you perform giveback to new switches, so you should really plan maintenance window for such activity.

There is really no point in jumping through extra update, if target is 8.2. What is important, old head should be updated to the same version as is installed on new head. I usually always use netboot to install specific release on new controller.

NetApp supports hot SAS port change, but I think it is supported starting with 8.2.1. See https://kb.netapp.com/support/index?page=content&id=2023388 For details. If you can arrange for downtime, it is always the safest bet.

If it gets different CID it means that client reconnects. There is nothing you can do from NetApp side short of banning the client entirely.

It has the same problem - IP address fails over to another port, but host has connection to old port that does not work anymore.

Did you install FCP license?

NetApp dump stream should be compatible with ufsdump/ufsrestore; at least in the past people reported success with reading them on Solaris. You probably lose ACLs etc but file content should be accessible.

aborzenkov · ‎2015-08-20

That's bad idea and I am not sure if NetApp even allows it. For drive replacement both drives must be removed, so NetApp needs to evacuate second drive as well. For that both drives need to belong to the same node.

Your link is for FlexArray Virtualization Installation Requirements and Reference Guide. And this document now in multiple places refers to FlexArray Virtualization Best Practice Guide. See e.g. page 40: Note: The supported number of visible array LUNs on an FC initiator port varies according to Data ONTAP release. See the FlexArray Virtualization Best Practices Guide for information about this limit for the release running on your system. etc etc etc

aborzenkov · ‎2015-08-18

Doumentation (e.g. FlexArray Installation Requirements and Reference Guide) mentions it several times. I cannot find document with this title anywhere. Could someone provide a link?

Minimal file size is 4K, that gives you theoretical maximum of number of files in a volume. File count is per flexible volume, it should not affect other volumes in the same aggregate.

aborzenkov · ‎2015-08-17

If you can use thin provisioning (you did not mention whether your volume/LUNs are thick or thin), you could simply disable space reservation on volume and LUNs, run space reclamation and wait until snapshots age off. Note that as long as snapshots exist space reclamation won't free any space for you. If you must use thick provisioning the only way is to create new volume and Storage vMotion data there. You lose your existing snapshots in this case. You cannot both keep snapshots and free space.

aborzenkov · ‎2015-08-17

Can I reduce the size of the flexvol and LUN dynamically using OnCommand Manager? Yes. Can I do this while the VMs are running? Yes for FlexVol, no for LUN. It has nothing to do with NetApp - you cannot reduce size of VMFS. Is there a process I can run on the filer to move the snapshots from old volume to new volume? SnapMirror, vol copy, but I do not see how it helps you. You will get exactly the same LUNs that you want to get rid of.

aborzenkov · ‎2015-08-17

Any chance it can be addedd to configuration maximums document? Oh, and what about number of broadcast domains? 🙂

Base cluster license is not associated with specific hardware serial number. Search for sales order; it should be part of the same sales order as protocol licenses.

It is not very obvious, at least mobile version. It never really says there is single power supply for both cases. Actually, it lists two FRU numbers for PSU without much info what the difference is.
