SAS controller limitations.
by Jeff Cleverley 01 Jun '14

01 Jun '14

Greetings, A while back there was a known issue with the SAS controller. Each chip that controlled 2 ports would only address 128 devices. That included shelf controllers so technically 5 ds2246 shelves would exceed the limit and could cause some slowness. I was told that they changed this behavior in 8.1 and possibly upgrading the firmware, so that it only kept active devices in the list. I was told those devices would be removed when not active and so there was no need to keep the … [View More]

Oracle access and backups
by Jeff Cleverley 28 May '14

28 May '14

Greetings, My Oracle experience with and without NetApp has largely been non-existent. Please bear with me on this. All of our current DBs are on dedicated servers with locally attached storage. One of our groups has a 6280 cluster running 8.1.2P4 7-mode. They want to look into using iscsi to a new 11.2 Oracle server. The cluster can get pretty busy at times so I'm not sure Oracle NFS will work in this case. The questions are largely about backups and DR. I'm curious about how most … [View More]

OnCommand Balance Question
by Ray Van Dolson 23 May '14

23 May '14

Running OnCommand Balance 4.1.0.2.9 Not an expert with it tool and looking for a "quick" fix here, though obviously reading through the manual more thoroughly is on the TODO list (Google search didn't net me anything). Overnight, have had some growth on one of our VMware volumes (NFS attached volume). System Management Console shows that heavier than normal write activity began overnight and is ongoing. Balance shows the same, but I'd like to see which VM living on the volume is responsible … [View More]

Migrating from copper gigabit to fiber 10Gb
by Laurent CARON 19 May '14

19 May '14

Hi, I'm currently planning to migrate my FAS2240's ggiabit links to 10Gb links. Since the 10Gb cards are already in place in the filers, the physical part is already done. I'm currently using the 4 Gb links (e0a -> e0d) as a LACP connection to a stack of juniper devices. Providing the config is OK on the switch, what woule be the best way to migrate with the minimum downtime ? I'm planning the following (on each node of the box): - make sure config on the 10Gb ports of the switch is … [View More]

Migrating from 7-Mode to CDOT without downtime
by Alexander Griesser 18 May '14

18 May '14

Hey there, we're getting a new FAS8020 during the next weeks and my task now is to move all the data on our current 7 mode filers onto the new one. I've already made non disruptive plans for the VMware datastores and all the NFS shares, so that's not an issue anymore - but I'm wondering about how to non disruptively migrate my iSCSI LUNs presented to my microsoft failover clusters. Any ideas on that? I'm thinking about setting up some kind of software RAID 1 (if that's supported) on the host … [View More]

heartbleed -- Netapp SSL
by Douglas Siggins 12 May '14

12 May '14

Greetings, Looking for a quick way to determine what versions of SSL are in use in DOT (7-mode). I could not find anything specific. http://heartbleed.com/ I assume the version of SSL is probably not 1.0.1 - 1.0.1f on the Netapps. Anyone have any ideas where to look?

OSSV server database cleanup
by Jeff Cleverley 08 May '14

08 May '14

Greetings, I was hoping for a quick fix since it is Friday afternoon. If nothing works out I may open a call or just wipe everything out. We have OSSV3.0 running on a linux server. It is installed on / and filled up / today. I found a -checksums file dated today that is 30G. There is another one for the same date last month of the same size. No other checksums file is larger than 10G. The file system that backups up on the 11th of the month is smaller and has considerably fewer inodes … [View More]

How to force a particular access with NTFS permissions
by Jeremy Webber 05 May '14

05 May '14

Hi, We have a number of volumes on NetApp filers (OnTAP 8.1.2 7-mode) configured with NTFS permissions. The problem is that users, via their windows clients, sometimes set permissions so that administrators, including the backup software (which is in the "Backup Operators" group) cannot see data. Is there a way that I can add an ACE to all files and directories in a qtree without interfering with existing ACEs? I’ve tried using the storage-level security guard but this does not appear to … [View More]

FCP switch / port info
by Momonth 05 May '14

05 May '14

Hi All, With OnTAP 8.x (afaik), it became possible to see what FC switch name / port number a filer is connected to on SAN: filer> fcp show adapters -v .. Switch Port: fc-corp-203:22 // fc-corp-203 - switch name // 22 - port number I assume a certain FCP request makes it possible and wonder if a similar tool is available on a Linux server (Im running CentOS mainly). Is anybody aware of such a tool / utility? Cheers, Vladimir

OT: Converged Infrastructure
by Ray Van Dolson 02 May '14

02 May '14

Apologies if this is too off-topic. Still no SNIA sponsored list out there for general storage discussion that I'm aware of. :) This is more for the folks using their filers in tandem with VMware... Am curious how you toaster admins out there are reacting to all of the new-fangled converged options (Nutanix, Simplivity -- not so much the UCS/vBlock type stuff) out there? Dipping your toes in the water to experiment? Going all in with C-Mode and sticking with your NetApps plus traditional … [View More]
