OnCommand Performance Manager events
by Basil 25 Jun '15

25 Jun '15

I'm using 1.0.0 r2 with a CDOT cluster running 8.2.3. When I look at an event, it says things like "3 victim volumes slow due to 5 bully volumes causing contention on aggr_SAS". When I drill in, I can see a list of volumes with their latency at that period, but no indication whether they're being considered victims or bullies. Has anyone had any experience with this software? Another question- is there a way to look directly at an aggregate's utilization? If I drill into a volume, I can see the aggregate with "break down data by - components - disk operations", but that doesn't show me the aggregate itself. Just the contribution of this volume to the aggregate. When I look into an event, the aggregate utilization is listed, but I can't get to there on its own page with a controllable graph. Lastly, if I know an aggregate is being pushed to 100% but I can't see any volumes pushing harder, is there a way I can check whether system work is responsible? My first thought was that it was dedupe, but that's scheduled to kick off with the lowest possible priority about two hours after this event occurred. Cheers! Basil

NetApp and Unix UID
by Edward Rolison 25 Jun '15

25 Jun '15

Perhaps a slightly daft question, but I can't find the answer rummaging. Someone's just asked if there's a problem with going past 16 bit UIDs (>65535). Is anyone able to point me in the right direction?

Yes, and when I'm just looking to see what just happened, that's where I go. When I'm looking to have something light up at the command center to generate an off-hours page, though, we use specific SNMP software (HP Openview, to be specific) and we try to use it whenever possible.

snmp and cdot 8.3
by Sayla, Mustafa 22 Jun '15

22 Jun '15

Anyone has experience with monitoring CDOT 8.3 with snmp? I have configured the CDOT system and configured SNMP trap host and community string yet we are not receiving traps. We were told by our third party vendor Solar Winds that netapp does not use standard snmp OID. We are not using snmp v3.

Recommendations on preserving a filers data?
by Arnold de Leon 22 Jun '15

22 Jun '15

What are the recommendations for the "best" way to preserve a copy data on a filer for future use? Background: A company has ceased operations and wants to preserve copies of its data "just in case someone wants it in the future". All the interesting data has been copied to the a single "archive" filer. There are about eight volumes in using about 50TB (with dedupe but no compression). This will be backup copy #1. The other filers that previously held the data are being sold and scheduled to be wiped. The data is a mixed of virtual machines and file shares. Now I'm trying to see if if a way to make another copy of the data for safe keeping at a reasonable cost. Speed of restore would not be high the feature list of this secondary archive. One of the first thoughts simply dump the data onto an AWS volume for "cold storage". Sane? Tips/tricks? Data presumably gets scrubbed to prevent bit rot. Conveniently available just about anywhere. Has a recurring cost but avoids some upfront cost. Second thought is find a relatively inexpensive array of disks and dump the data to that. Most likely benefit is fastest to write to. Maybe cheapest but in the end all the data is on non-spinning disks without verification. Tapes? I don't like tapes. Don't know if a working tape system available but if there was is this a good case for it. Tape static storage better than disk? Thanks. arnold

Clustered ONTAP 8.2 routing
by Legato, John (NIH/NHLBI) [E] 17 Jun '15

17 Jun '15

Hello, We've recently acquired a 2 node FAS8020 cluster running Clustered DataONTAP 8.2. We inherited a rather unusual/silly network topology, in which we have two subnets (a publicly routable one and an RFC1918 one for internal use only) running on the same VLAN. In other words, there's no router between these two subnets. In Linux, we're able to get boxes on the publicly routable subnet to communicate with the internal subnet (10.1.0.0/16) as follows: route add -net 10.1.0.0 netmask 255.255.0.0 dev eth0 This command tells the Linux box that it can send packets to 10.1.0.0/16 hosts out eth0 without going through an intervening router. However, we've yet to find a way to do this with Cluster DataONTAP. We've played around with routing groups and routes, but we cannot figure out a way to tell Clustered DataONTAP to route through an interface. Does anyone know if this is possible? NetApp has advised us to set up a router between our two subnets. We share NetApp's concern over fail over We'll set up a router if we can't figure out any other way to make this work. Thanks John

issue with Ontap upgrade 7mode system
by Sayla, Mustafa 15 Jun '15

15 Jun '15

I recently upgraded one of my 7mode controller from 8.1P1 to 8.2.3P3 and ran into issue during the second controller upgrade. I installed the upgrade version on both the controller than performed the cf takeover from controller B to controller A and it went fine. I then waited about 10 minutes and did the cf giveback and that also went fine. after waiting another 10 minutes I tried the cf takeover from controller A to controller B and I got the version mismatch error. I then issued cf takeover -n and at the time controller A did not took over controller B but just rebooted controller B. This caused a downtime with our vmware farm as servers lost connection to the data store on controller B. This is with NFS protocol. I only see this error in the logs Fri May 29 15:53:59 CDT [rddata1b: cf_takeover: kern.rc.msg:notice]: vlan: interface creation failed due to internal errors Partner vlan create command failed This explains why the takeover did not work but does not explain why this happened in the first place. I have worked with Netapp and validated that the rc file is correct and we have done failover and failback in the past without any issue. I also did the failover and failback after this to rule out configuration issue but could not recreate it. I need to upgrade 3 more HA pairs and I want to know if anyone has seen this issue before and does this have anything to do with the upgrade.

cifs.smb2.client.enable
by Ray Van Dolson 15 Jun '15

15 Jun '15

cifs.smb2.client.enable This option enables SMB 2.0 client capability on the Filer. When this option is enabled, Filer-initiated connections to Windows servers use the SMB 2.0 protocol. If the Windows server does not support the SMB 2.0 protocol, the Filer uses SMB 1.0. If a session was established over SMB 2.0 and then this option is disabled, existing sessions are not terminated. The Filer continues to use SMB 2.0 for the existing sessions; new sessions do not use SMB 2.0. Probably missing something obvious -- but would someone describe to me a scenario in which the NetApp would act as a CIFS client? Thanks, Ray

unified manager for CDOT 8.3
by Sayla, Mustafa 13 Jun '15

13 Jun '15

We recently installed our first CDOT system with 8.3P1 and now I want to setup the monitoring and configuration environment for it. I have few questions * Do I need a separate OnCommand Server for CDOT or I can use my existing server that I use to manage my 7mode systems. My current system is using OnCommand 5.1. * We are on Vsphere 5.0 and per admin guide it seems like I cannot use Unified Manager 6.2 so can I use Unified Manager 6.1 with CDOT 8.3P1 * Is performance manager part of unified Manager or it is a separate appliance. What I want to know that if I download and install the unified manager appliance do I get performance manager as part of it or I have to download performance manager appliance separately and install it as a separate VM Thank you Mustafa Sayla Visit us on the Web at mesirowfinancial.com This communication may contain privileged and/or confidential information.
