cDOT cluster net flow control?
by Mike Thompson 31 Oct '14

31 Oct '14

Hey all, I have two ancient 8.0.5 cDOT clusters running several 6080s with pairs of Cisco 5010s for 10gig cluster net, 2 x 10gig cluster ports per filer (can't upgrade them, no support, long story..) Anyway, just recently one of these clusters started periodically spewing some partial and full packet loss errors on the cluster net - multiple filers, multiple ports, not local to a specific cluster switch. Tried powering off each cluster switch, I get the same thing whether it's one, the other, or both switches in play. I notice that flow control is enabled on the ports filer-side, but not on the cluster switches. I never really paid any attention to that, as they came from NetApp in this config, and have been working fine to date. However now that I've been doing some digging, I see a lot of mentions that it's recommended that flow-control be disabled completely on 10 gigabit gear with NetApp. Since it's enabled on the filers, but not on the cluster switches, it's effectively off anyway, right? Or am I missing something? The switches see plenty of pause frames coming in from the filers, so it would appear they are wanting things to slow down. I'm wondering if I'm hitting some threshold on the filers that's causing this periodic packet loss. It's not associated with a specific port, so doesn't appear to be a specific optic burning out, and it's present regardless of using either or both switches. stats periodic only shows a GB or so passing over the net between these 8 x 6080s, and ops cluster wide are not that high at all, so I'm kinda stumped. I've dealt with plenty of bad optics in the past, and we usually run out of steam and the disk or head level, so these cluster net issues are new to me. My thought is to go ahead and try enabling flow control on the switches, but that seems to be recommended against. Any ideas?

SP Firmware Failing

Hello- I have a 2240-2 and I am attempting to upgrade to SP firmware to version 2.2.2P2. I keep getting 'ERROR: Metadata absent in new package' when attempting to install the firmware.

However, attempting to upgrade to 2.2, 2.2.1 or 2.2.2P2 are failing SP toaster> version Booted primary firmware version 2.1.3 Booted primary ACP version 01.10 Primary firmware version 2.1.3 Primary ACP version 01.10 Backup firmware version 2.1.3 Backup ACP version 01.10 SP toaster> sp update http://www/~steven/306-02160_A0_SP_2.2_SP_FW.tar.gz Downloading package...

In place 32-64bit aggr upgrade
by Fred Grieco 22 Oct '14

22 Oct '14

Has anyone tried the priv set diag "aggr 64bit-upgrade start aggr1 -mode grow-all" command? I am entertaining doing this in 7 mode. Also, it says something about growing the volume. How much does it grow the volume by? TIA, Fred

Antwort: Re: Access to deprecated home share
by Markus.Schlegel＠roto-frank.com 21 Oct '14

Hi Basil, thank you for your reply. I found out that \\filer\%username% works, but \\filer\~ does not. Thats why it worked with some userprofiles. We've changed the profiles to point to \\filer\%username% and it works now for everyone, but i still receive a lot of these warning inside my messages log. Maybe it has something to do with these undocumented options i couldn't find any info to. cifs homedir showuser always points to the correct directory. Ownership is also correct.

For a user where this doesn't work, please try cifs homedir showuser hute, as well as check that the owner of the folder is the user. I know the user has access, but apparently ownership matters with some configurations.

Access to deprecated home share

CIFS joining a filer to a read only domain controller.
by Edward Rolison 14 Oct '14

14 Oct '14

I've found: https://kb.netapp.com/support/index?page=content&id=1012918 Which basically says - try pointing your filer at a writable DC. That's difficult, for a variety of reasons - not least because this is an isolated network segment, and the vfiler is in it's own IP space. Does anyone know a better way of joining the domain? On a standalone Linux/Windows box, I can manually create machine accounts and set necessary passwords. The firewall is run by a separate team, and so temporary rules for this purpose is a nuisance. (Probably not _completely_ impossible though). Has anyone done this and come up with a better solution? The 'domain join' process isn't _that_ complicated, in that all it's doing is generating a local kerberos keytab and setting a local shared secret. Thanks and regards, Ed Rolison

Question regarding NVRAM battery
by Camillo Gornati 08 Oct '14

08 Oct '14

Hello all! We have 4 net app systems a FAS2020, 2 x FAS2020a and one FAS2040. The FAS2040 had a NVRAM battery losing power until it shut down because of the battery not having power. Purchased a battery, replaced, and still no charge. Now we though the problem was the controller, so i purchased a new controller, replaced CF CARD and inserted back in the chassis, noticed battery wasn’t charging either, now controller has shut down again and battery is not charging. Could someone give me a light on this one? Firmware issue? Thanks again!
