Not sure where I can post this at all ... HW Universe stopped working after (more or less forced) update to IOS 11. Version on appstore is 4 years old. Is it no more maintained? Pity, actually ...

aborzenkov · ‎2018-03-13

There is no way to remove data disks from aggregate. It is possible to convert RAID_DP into RAID4 by removing one parity disk (but RAID4 is frowned upon today). Alternatively you can build new aggregate (it can use minimal number of disks initially, even 2, so you can utilize existing spares) and relocate root volume to this aggregate, then destroy original root aggergate. Relocating root volume is possible non-disruptively in your case (but see http://community.netapp.com/t5/Data-ONTAP-Discussions/Epsilon-and-root-move-from-an-aggregate-to-anoter/m-p/138789#M30619 for caveats).

@AlexDawson wrote: then reapply permissions for the other protocol. That made me scratch my head. Until now I was sure that FAS only keeps one set of permissions for each file and emulates "other" permissions. This is the first time I hear that FAS may have two independent permission sets for NFS and CIFS. Could you clarify how is it possible (what security style)?

The only known way is aggregate snapshots.

You confused SAS HBA and NVRAM. Your filer does not have SAS (which is expected for metrocluster configuration). So your only option is shelf connection via FC bridge. If you are going to actually use those filers, you better interconnect NVRAM as well to have HA. If not using FC-VI, cables are the same as for SAS shelves. What is the reason to sanitize disks? It is not needed if you want to reuse them.

Any chance to use it for software/firmware updates with ONTAP 9?

aborzenkov · ‎2018-03-01

It sounds like you got metrocluster. I strongly recommend you to arrange for professional service from NetApp or partner. Setting up metrocluster needs some experience and far exceeds forum format.

aborzenkov · ‎2018-02-25

Apparently your filer still believes it is part of HA Pair. Boot into maintenance mode and use ha-config command to check and if necessary reset HA state. Also you may need to remove partner-sysid loader variable. https://library.netapp.com/ecmdocs/ECMP1367947/html/GUID-14AF35BF-BC87-4226-801D-ED0CF3FA0B0F.html https://library.netapp.com/ecmdocs/ECMP1210206/html/GUID-F8FF2BB3-38C4-4FBD-A152-0941CA645559.html

If you really has single node, you may need to verify that filer is not configured for HA. What "cf status" says now?

aborzenkov · ‎2018-02-25

And if you use -f (force) option? Alternatively try "disk assign 0b.11.21 -s unowned -f"

It is not clear from this link if it is possible to download more than one version in cluster update repository.

If there are disks that are already owned by a node, 4a only initializes these disks. So apparently other shelf was owned by some other node. Just remove disk ownership and reassign.

aborzenkov · ‎2018-02-22

I do not think you can partition external shelves on this platform. Internal disks are partitioned by default. Mixing partitioned and non-partitioned drives in the same aggregate is supported. Usual considerations for non-uniform configurations apply - it complicates administration and troubleshooting. May be you could assign all data partitions to one node and all whole disks to another node?

SSDs remain unpartitioned for use as Flash Pool cache". Either this document is wrong or system was ordered as SSD-only with second shelf as loose delivery. BTW if document is correct, it means that there was no need to unplug SSD during initialization - it would already set it up exactly as desired.

aborzenkov · ‎2018-02-17

There is no documented way to move shelf with data between nodes in cDOT. Option 2 is about replacing nodes themselves. Nodes fully retain their identity in cluster, their shelves still continue to belong them.

aborzenkov · ‎2018-02-17

I wonder how external shelf got partitioned after initial installation in the first place. As far as I know this should not happen.

aborzenkov · ‎2018-02-16

It should just work. SnapMirror works in pull mode, so destination should simply continue existing relationships as long as new IP is allowed for SnapMirror access to source.

aborzenkov · ‎2018-02-14

Did you check that new IP is allowed snapmirror access on source?

aborzenkov · ‎2018-02-12

This specific bug is stated to be fixed in both 9.1 and 9.2RC1. May be there are other conditions that trigger this problem?

aborzenkov · ‎2018-02-07

My gut feeling is that integrated systems (which AFF A200 is) default to even/odd bay . But yes, I'd love to see defaults explained somewhere, including description of what "bay" disk auto assignment policy actually does.

aborzenkov · ‎2018-02-03

Are you speaking about FAS adapter or server adapter? What is exact model number?

aborzenkov · ‎2018-02-02

Well, it still does not work. I PM you my e-mail.

Tried both with 7-Mode and C-Mode. In both cases serial port definitely works with PuTTY, speed in Device Manager is correct (9600 for the hardware in question). If NetApp console is connected, adding new job and pressing Validate results in ERROR: 'Stopping Data collection through SplSerial. Exception on COM2 - 'SplSerialConnection' object has no attribute 'hostname'' To verify I tried without anything connected to port at all and I get other error, so apparently CA does attempt to contact FAS: ERROR: 'Stopping Data collection through Serial. Login/Transport on COM3 - 'No response from the serial connection.'' Nothing in logs except the above message. Note that it is not ucommon to have customers who do not allow attaching to their network and serial post remains basically the only possibility. Oh, and when I chose Device Based data collection job, it does not even offer me serial port! Really frustrated. And this after so well working older versions ... P.S. WTF, why must I label this post with entirely meaningless label?
