Random/Sequential measurement on Filers
by Martin 24 Jan '14

24 Jan '14

Hi, I'm trying to characterize the workload on our Netapp Filer running VMware over NFS and iSCSI for benchmarking purposes using IOmeter. Is it possible to determine what the percentage random sequential distribution the workload is on a Filer e.g from a perfstat? I've looked at vscsiStats but that is only per VM and not for the aggregate workload on the Filer. -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/Random-Sequential-mea… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

flow control and 10g interfaces - ifgrps and vlans
by Jordan Slingerland 22 Jan '14

22 Jan '14

Can flow control be disabled on a vlan interface? I tried in a simulator and It spits back "SIOCSFLOWCONTROL - Operation not supported by device" In the same simulator I can enable or disable it directly on the interface. Example RC: hostname toasterA ifgrp create lacp nfs_ifgrp -b mac e2b e1b vlan create -g off nfs_ifgrp 100 ifconfig e0M 192.168.1.100 flowcontrol none netmask 255.255.255.0 partner e0M up ifconfig nfs_ifgrp-100 192.168.0.100 flowcontrol none netmask 255.255.255.0 mtusize 1500 partner nfs_ifgrp-100 trusted up nfo route add default 192.168.0.1 --Jordan For the seventh consecutive year, Independent Health was named one of the best companies to work for in New York State.

reallocate effect on snapmirror and snapvault
by rrhodes＠firstenergycorp.com 20 Jan '14

20 Jan '14

Hi, I'm thinking of running a "reallocate start -p" on a couple volumes that are showing high latency disk accesses for luns. The volume is a source for both snapmirror and snapvault operations. I was reading up on this command and I can't find any real info on the effect of running this on the snapmirror and snapvault operations. Question: If I run a "reallocate start -p" on a volume, will snapmirror/snapvault see this and send all reallocated blocks? Also, can snapmirror/snapvault operations be running during the reallocate?

Consistency Point Type M

Good morning, does anyone know what consistency point type M is and what's causing it?

igroup setup for a cluster
by rrhodes＠firstenergycorp.com 15 Jan '14

15 Jan '14

What's the best practice for setting up igroups and lun mapping for a cluster? Last night we moved a cluster that uses luns on Netapp (IBM Nseries) to new servers. The old servers used internal boot disk, while the new use san boot. I had it setup like this (names are different!): Igroup: serverA_boot wwnA1 wwnA2 boot_lun_mapped_in_lunid0 Igroup: serverB_boot wwnB1 wwnB2 boot_lun_mapped_in_lunid0 Igroup: cluster_luns all_the_cluster_luns_mapped_in_lunid0-149 During the cutover, I went to add all 4 wwn's (wwA1,wwnA2,wwnB1,wwnB2) into the cluster igroup. I was swinging the luns from the old server with internal boot to the new san boot servers and got an error. It complained that I couldn't put the new wwn's into the cluster igroup for luns because the boot igroups already had a lun id 0, and the cluster igroup also had a lun id 0. That is, the same wwn can't map to duplicate lun id addresses. To fix, I simply remapped the cluster lun at id 0 to the next highest value, then I could add the wwn's and all was well. Question: Is this the best way to create a san boot cluster? Is there a better way? The next time I create a cluster lun It will be interesting what lun id gets assigned - lun id 0 (and get an error), or the next hightest. I also thought of just mapping the cluster luns to both boot igroups, but like that a cluster lun igroup is kind of self documenting. Thanks for any ideas!

Netapp is great and always will be 1st tier storage, But for many of our new use cases (SMB customers, IOPS over capacity etc) we are looking for lower cost solutions to compliment (work well with support wise) our huge ONTAP base. What other solutions have others found compliments their Netapp ecosystem ? (NB: we are running multiple 8.1.2 (7 mode) clusters and value the robust snapmirror, vfiler migration featureset thanks
