Raidgroupsize and I/O Performance
by Steffen Knauf 22 Oct '12

22 Oct '12

Hello, i'll try to improve our I/0 Perfomance. We have a raidgroup with 16 disks (SAS), 1 aggregate and 1 volume (dedup enabled). The volume is the storage for 100 VM's on the VMware Cluser (access via NFS). Does it make sense to increase the raidgroup? 90% Percent of the Disk I/O are Read Ops, so i'll buy a PAM Card for our FAS3240,too. And what's your Experience with the Raidgroupsize of a Raidgroup with SATA Disks (now: 11+1)? Thanks and greets ! Steffen

NSF client listing
by Weasner, Matthew K 19 Oct '12

19 Oct '12

This is probably a silly question, but what is the most reliable way to get a list of NFS clients that have an export mounted? OnTap 7.3.3, and the share is exported R/W to the world.

simulator 8.1.1 VMware appliance?
by Randy Rue 04 Oct '12

04 Oct '12

I'm a little torqued that NetApp has opted to change from a tarball that installs on a linux platform to a virtual appliance approach. In this case I've trying to test for an upgrade from 7.3.5 to 8.1.1 and even if the upgrade proces is different for a simulator I'd like to be able to upgrade the simulator in place to confirm that iSCSI clients can connect to existing LUNs. I did try to upgrade the simulator using the same packages the physical filer will use (v3170 HA pair) with no luck. Tried both packages from the NA download site and on "software update <file> -r" both complain about the wrong CPU architecture and bail out. So now I've moved on to bringing up an 8.1.1 simulator and maybe using ndmpcopy or snapmirror to migrate those LUNs. But still having trouble. The tarball I downloaded for the 8.1.1 VM doesn't have any VMX file in it, just a pair of VMDKs? VWware player won't let me create a new VM and then reassign a different disk? We do run vSphere here but the old simulator required the NICs to run in promiscuous mode, is that still the case? If so, I'm not inclined to put the sim on our production VM farm as it would mean tweaking production network interfaces. Anyone had any luck with the 8.x VMware appliance simulator and VMware Player?

is the filer "telnet' command
by Iluhes 04 Oct '12

04 Oct '12

I need to check if the firewall is open between filers on snapmirror ports. I cannot find a "telnet" command so I can telnet from fi ler to to filer on specific port. How do I check from filer CMD line if the ports on the snapmirror partner are open Thanks!

simple max spindles question
by Owen.Beckley＠sungard.com 27 Sep '12

27 Sep '12

I have a simple question about an old FAS3020 HA pair that we have. I looked it up in the Hardware Universe tool and it says that the maximum spindle count is 168. Is this the maximum for the pair, or per head? In a failover scenario, can the system only handle 168 spindles total, or 336 total?

E2K10 on VMWARE. Which best practice?
by Milazzo Giacomo 27 Sep '12

27 Sep '12

Hi all, a couple of time I've experienced some performances issues with Exchange 2010 installed on "luns" on a NetApp filer. Worst cases of course when I've some secondary passive DAG setup on SATA aggregates. I've almost read everything about best practice both on VMware FC SAN storage and Exchange natively setup on FC LUNs; there's also a very interesting TR about E2K10 on 2240 FAS with SATA only! But there's something not clear. In this environment: Storage NetApp vSphere 5.1 E2K10 Vdisk diretti (non rdm) Datastore FCP Which are the parameters you consider to best optimize everything? The VMware ones? The Exchange ones? A mean between the two? :) I.e are read_realloc or extent options really useful? Regards, Dott.

R: Upgrading SnapDrive without reconnecting LUNs?
by Milazzo Giacomo 26 Sep '12

26 Sep '12

But if that was passive why it had LUNs connected? Maybe do you mean with init logged in? On passive node you should be able to power off the LAN connections too without for this to loose volumes in the cluster container... Old SD works we know but we also know that works is not supports :-) 6.4 is in the matrix. -----Messaggio originale----- Da: Randy Rue [mailto:rrue@fhcrc.org] Inviato: sabato 22 settembre 2012 21:53 A: Milazzo Giacomo Cc: Steve Klise; toasters(a)teaparty.net Oggetto: Re: R: Upgrading SnapDrive without reconnecting LUNs? Our DBA upgraded the passive node first, that's when the LUNs all disconnected. BTW, I got confirmation from our NA SE that while older versions of SD might definitely work with DOT 8.1.1, the support matrix does require SD 6.4+ ----- Original Message ----- From: "Milazzo Giacomo" <G.Milazzo(a)sinergy.it> To: "Randy Rue" <rrue(a)fhcrc.org> Cc: "Steve Klise" <klises(a)sutterhealth.org>, toasters(a)teaparty.net Sent: Saturday, September 22, 2012 12:24:58 PM Subject: R: Upgrading SnapDrive without reconnecting LUNs? Mh. Sound strange. SD is a service running on top of volume manager...I've never had issue upgrading it: this does not cause communication interruption with LUNs I read about iSCSI, maybe something is wrong in the service dependency so that SD kill the iSCSI initiator too? Anyway the road to upgrade the passive node first is the good one.

What I have done in the past, was to get on the active node, update snapdrive, then update the passive node (assuming you are doing active/passive). All nodes should be at the same version. So, these are the steps I have done. You will also have to update the SMSQL to the same version as well. Update snapdrive (may need to install hot fixes) update SnapManager If you are using MPIO, update (may need to install hotfixes) last step, install Netapp Host Utilities I hate Microsoft clustering.. Sucks, and it can be complicated and a pain when it breaks. Hope this helps.

Hello All, We're preparing to upgrade a v3170 running 7.3.5 to 8.1.1 and will first need to upgrade a number of SnapDrive clients to 6.4 or higher. Our DBA's are testing the SnapDrive upgrade and so far have been unable to do so without needing to recreate all their connections (essentially the iSCSI disks mounted in the SQL cluster go away and they need to reconnect to the LUNs). Is there a better way to do this? Seems like in a perfect world, we'd just run some .exe to upgrade SnapDrive, reboot and find all as it was?
