Netapp and VMware... It's all so confusing!
by Timothy Hollingworth 01 Apr '10

01 Apr '10

So, say for example, I want to virtualize an Exchange server. Lets also say that I want to manage it via Snapdrive and SME. Lets also say, just for the heck of it, that I want both the new front-engined Acura NSX as well as the Porsche RC3. The cars aside, I would have to run iSCSI from within the VM, install and use Snapdrive from within the VM to provision LUNs, install Exchange and then use SME? It seems kind of silly to use iSCSI from within a VM if the ESX box were fiber attached to the Filer, just to be able to use Snapdrive and SME, no? I would love to be able to use the features of SD and SME within a completely virtual environment and am wondering what some real world implementations other VMware/Netapp customers are running. Do you run storage for the databases and logs in VMDK's and manage snapshots and backups from a VMware virtual machine perspective or do you manage them as iSCSI LUNs and use SD and SME? Or am I completely blind and missing something? Timothy L. Hollingworth Sr. Network Engineer, ePlus Technology Inc. 678.462.6698 (cell) AIM: HollingworthTim YIM: t_holling

how to "move" an existing snapmirror to new network interfaces?
by Todd C. Merrill 18 Aug '08

18 Aug '08

I have lots of existing q-tree snapmirrrors of the form: srcfiler:/vol/volM/qtreeX destfiler:/vol/volN/qtreeY "srcfiler" (DNS name) is the e11 interface on srcfiler "destfiler" (DNS name) is the e9a interface on destfiler We just built a "dedicated snapmirror/backup" network and added the following: "srcfiler-backup" (DNS name) is the e0 inteface on srcfiler "destfiler-backup" (DNS name) is the e11a interface on destfiler Subsequent 'snapmirror update -S ...' commands (we don't use snapmirror.conf) still use the non "-backup" network links. I'm not seeing the counters on the "-backup" links increment via the `ifstat` command. The $64,000 question: --------------------- How do I "move" these snapmirrors to the "-backup" network links...without, of course, re-initializing them? I'm expecting, in the end, to see `snapmirror status` give back to me: srcfiler-backup:/vol/volM/qtreeX destfiler-backup:/vol/volN/qtreeY and see the counters on e0 on srcfiler and e11a on destfiler increment.

Hello Toasters I'm going to implement Iscsi network on solaris 9 machine and FAS2020 cluster As you know iscsi software initiator is available only on solaris 10 and it's possible to achieve failover in with IPMP and software initiator since i will be using solaris 9 machine i need hardware initiator in my case i will be using 2 qla4010c is it possible to achieve redundancy at the host side ( HBA failover \ multipathing) in this configuration if so how ?

Migrating data without service interruption : 3020 -> 3140
by Simon Vallet 28 Jul '08

28 Jul '08

Hi, we just received a new 3140 cluster here to upgrade an existing 3020c production filer. And now we're looking for a way to migrate the existing data (~18TB) with the least possible downtime. Ideally, we would use SnapMirror to copy the data on the new filer and then transparently (for clients) switch the production system, similarly to what happens when a cluster member fails over to the other member. But we don't know if this is possible. So the questions are: - do you think such a procedure could be successful ? - do you have any other ideas to migrate the data without service interruption ?

Has anybody configured a IBM 3592 E5 Tape drive off of an R200 via Fiber Channel ? I'm hoping to configure it via the newly zoned port on my X1028A. TIA -Robert

No problem. We tried http, https & smtp, but no real difference. Sláinte, David Give a man a fire and he's warm for the day.

Weird autosupport problem
by David McWilliams 23 Jul '08

23 Jul '08

Autosupport worked fine up until about six weeks ago, no it doesn't. We can't think of anything that changed in the environment. We can ping the mailserver, I tried telnetting to the mailserver on port 25 to see if it is still relaying, seems to be OK. We weren't seeing any messages at all regarding autosupport in the messages file, an time we tested. We just changed the transport to smtp, from https, and we now get one message, but that's all, see below. netapp2050a> df -h Filesystem total used avail capacity Mounted on /vol/rootvol/ 20GB 197MB 19GB 1% /vol/rootvol/ /vol/rootvol/.snapshot 0TB 0TB 0TB ---% /vol/rootvol/.snapshot netapp2050a> options autosupport autosupport.cifs.verbose off autosupport.content complete autosupport.doit DONT autosupport.enable on autosupport.from netappalert(a)###.com <netappalert(a)plastipak.com> autosupport.local.nht_data.enable off autosupport.local.performance_data.enable off autosupport.mailhost 10.1.1.130 autosupport.minimal.subject.id hostname autosupport.nht_data.enable on autosupport.noteto helpdeskteam(a)###.com<jlalik@plastipak.com,helpdeskteam@plastipak.com> autosupport.performance_data.enable on autosupport.retry.count 15 (value might be overwritten in takeover) autosupport.retry.interval 4m (value might be overwritten in takeover) autosupport.support.enable on autosupport.support.proxy autosupport.support.to autosupport(a)netapp.com autosupport.support.transport http autosupport.support.url support.netapp.com/asupprod/post/1.0/postAsup autosupport.throttle on autosupport.to admin(a)###.com<lkostoff@platipak.com,bblair@plastipak.com> From the messages file Wed Jul 23 11:04:38 EDT [netapp2050a: asup.general.drop:error]: Out of messages for autosupport, skipping autosupport: USER_TRIGGERED (test) The machine is running 7.2.2L1.
