RE: Snapmirror initialization aborts consistently
by Mike Partyka 14 Dec '07

14 Dec '07

Yes, although it from the source logs you can see it doesn't hang in the "exact" same place it's always around 83G transferred. I reconfigured the VSM to a QSM this morning since it's really just qtree tree1 in the flexvol and it hung even sooner, at the 65G mark. I'm trying to get downtime to run wafl_iron at this point. I just don't know what else to do. -----Original Message----- From: Mailing Lists [mailto:mlists@uyema.net] Sent: Wed 11/7/2007 12:06 PM To: Mike Partyka Cc: NetApp Toasters List Subject: Re: Snapmirror initialization aborts consistently It isn't clear whether you tried initializing again where it left off. Does it abort without continuing past 83gb?

Aggregate shows need check
by Bryano 14 Dec '07

14 Dec '07

Hi, We have recently upgraded to 7.2.3 and have created an aggregate containing 2 flex volumes however I have recently noticed that the status of the aggregate shows 'need check'. According to the manuals this means that i need to run a wafl consistency check ran on it (Wafl_check), can I do this while the filer is online and serving data or do i have to boot the filer in to maintenance mode?. If i was to delete the aggregate and start again would I take it that would negate the need to run the wafl_check? reason I ask is that the volumes only contain test data and this is more feasable than bringing the whole filer down for several hours (its an R200) Thanks -- View this message in context: http://www.nabble.com/Aggregate-shows-need-check-tf4942880.html#a14149910 Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

traditional SnapVault destination vol to flex vol convertion question
by Bob Doho 11 Dec '07

11 Dec '07

Hi guys, We need to convert traditional SnapVault destination volume (2TB) on a R200 to flex volume. We want to keep the snapvault snapshot to avoid doing another base transfer from source located in another data center. VSM is not possible. QSM will not copy the snapshots. We have heard that there is a procedure with snapmirror –s options that do the trick. Can someone help us with that procedure? Many thanks in advance. Thanks,

Data Ontap "downgrade"
by Milazzo Giacomo 10 Dec '07

10 Dec '07

Hi All Maybe is a simple question for most of you but I've never done before and I want to be sure J I'm going to revert a 6030HA from 7.2.3 to 7.2.2 for Snapmirror (bidirectional) compliance to another 6030HA system already running 7.2.2 I've seen times ago a similar operation performed from a 7.2 to a 7.1 and I remember some special command to apply after the unzip/download phase of the preceding Data Ontap release. Is it so? I mean, there are special commands on cli or should I simply unzip the 7.2.2, living them the "download" command and a reboot as an "upgrade"? Or is there something other. My 6030HA is a NEW system, no volumes or other aggregate other that the aggr0/vol0 for the os Regards

But you don't need that to just go from 7.2.3 to 7.2.2. Simply download and reboot will do it. Davin.

httpd.access -- number of entries
by Willeke, Jochen 10 Dec '07

10 Dec '07

Hi Toaster, we currently have a problem with API access to the filers. We use options httpd.access and httpd.admin.access for enabling hosts for filer's API-control. We now use the API for several issues e.g. the save of our databases. Sadly we found out that there is a limit for these options as it is for trusted.hosts. You can only add a fixed number of entries to these options. I know that we are able to activate a whole subnet for accessing, but this is some how a security problem in my opinion. Has anyone a good idea how to deal with that situation?? Or has anybody knowledge if this restriction will be gone in future ontap releases?? Best regards and a nice weekend to the list Jochen

Snapvault and lrep_reader/writer
by John Stoffel 07 Dec '07

07 Dec '07

Hi all, Does anyone else here do SnapVault across the WAN across a long wide link (dual T3, 90+ msec delay) and get decent performance, esp for the initial copy of the volume(s) and/or qtree(s)? We've gone the route where I did an lrep_reader dump of a 3.8tb qtree (don't ask...) to local disks. Then I used a nice tool called 'bbcp' to push it all across the WAN so that I could actually *use* all my bandwidth. Regular SnapVault sucks for performance, it just can't push more than 15mb/s which stinks when you have dual T-3 (90mb/s) bandwidth. Using bbcp I can fill that pipe for days on end. So then once it's all across the WAN, I then used lrep_writer to dump the data to it's destination qtree. All fine and good, but then I have to start a regular snapvault to now catchup with all the data written during the 8+ days the first stage took. Sigh... Anyone know if I can lrep_reader/lrep_writer the next snapvault snapshot across as well, so I can push the data faster? Because each time the link goes down between the sites, I have to start all over again with the catchup snapvault transfer and it's killing me. Also, I'd love to be able to *know* how much data is left to copy from the source to the destination, but "snapvault status -l ...." doesn't give that sort of information. Or do I need to start using the 'snap delta' command and my own math to figure out things?

V-series metrocluster (v3020c) on top of a 2-site EMC Clariion CX3-40 or HDS USP-VM?
by Anton Opgenoort 06 Dec '07

06 Dec '07

Hi, We are in the process of selecting a v-series NetApp cluster, which will act as an iSCSI/NFS/CIFS NAS gateway with an EMC Clariion CX3-40 or HDS USP-VM providing the backend storage. It's residing in 2 datacenters with transparent vlan's between the two locations. The v-series will be configured as metrocluster, and will use SyncMirror on top of some dumb lun's as offered on each location by the respective CX3-40 or USP-VM of that location. There is some FUD surrounding me that this is a less than ideal situation (both stability and performance). Does anyone in the field have any experience with such a clustered HA setup? Thanks in advance, Anton aopgenoort at schubergphilis.com

Re: Can you allocate space from one aggregate to a volume on another?
by Robert Lazzurs 06 Dec '07

06 Dec '07

We are currently using VirtualIron which supports LiveMigrate. This requires that the LUN not change, it does not copy the storage data. Thanks however, take care.
