FCP Partner Path Misconfigured - Host I/O access through a non-primary and non-optimal path was detected.

Hello Toasters. I am receiving the following message from auto support: FCP Partner Path Misconfigured - Host I/O access through a non-primary and non-optimal path was detected. I have a single cluster acting in single fabric mode and it is wired up in the following way. Each host has an i-group on each node of the cluster for. Each of the netapp node is connected to sw1 and sw2 and hosts also has a path to sw1 and sw2. Why would the host access luns on N2 via partner node N1 --------------- --------------- { n1 } { n2 } | \ / | | \ / | | \ / | | \ / | --------------- --------------- { s1 } { s2 } \ / \ / --------------- { host }

Monitor a loop's utilization
by Romeo Theriault 18 Mar '09

18 Mar '09

Hello, I'm interested in monitoring our filers fiber channel loops (to the shelves) performance. I'd like to be able to see what the utilization of a particular (2g) loop to some of our disk shelves is. But more generally I'd like to just be able to monitor all of the loops utilization over time. I've looked through the stats command and the snmp mib but am not finding what I'm looking for but I may just be looking for the wrong thing. Is it possible to monitor the loop utilization and if so how? Thank for any help on this. -- Romeo Theriault System Administrator Information Technology Services

ONTAP SDK access?
by Ray Van Dolson 13 Mar '09

13 Mar '09

Hello all, I'm trying to figure out how to gain access to the ONTAP Developer SDK software. The ONTAP 7.3 sysadmin guide mentions the Network Appliance Advantage Developer Program, but the URL[1] there no longer works. And, in our case, although we have several FAS units, in this particular case we'd be working with an IBM n3600. Can we access these same SDK's through the IBM channel? Yes, we're starting to look into that but I'm hoping someone out there has been through this adventure before and can advise. :) Basically, our end goal is to be able to automate the creation and management of flexclone volumes. I'm sure we could script up a screen scraper type interfae, but these API's sound perfect. Just need to figure out how to use them and how to get access to documentation. Thanks for any pointers!

maximum agitation to a filer
by Willeke, Jochen 10 Mar '09

10 Mar '09

Hi toasters, does anybody have a clue whats the maximum agitation is, a filer can handle? Maybe there is an official statement from netapp?!? The background is, that our facility-department is planing to start some aktivities near to our datacenter and we are afraid of any impact and want to give them some limits. Thankful for any thoughts!

ESX FCP host utilities

Anyone expierence this? I've even tried creating the ports manually using esxcfg-firewall -o and restarting the mgmt services. root@bc-esx02 /]# cd /vmfs/volumes/bc-esx02\:storage1/netapp_esx_host_utilities_5_0R2 [root@bc-esx02 netapp_esx_host_utilities_5_0R2]# ./install Would you like use SSL to securely connect to your NetApp storage system(s) (yes or no)?> no These tools require several ports to be open in the ESX firewall.

vmware ESX and volumes/aggrs
by steve klise 07 Mar '09

07 Mar '09

I was always under the impression you wanted to put as many disks into an aggr, then setup the volumes inside the aggr. Here is what we are doing, and I am just trying to see what others are doing, best practices, etc. We have an AGGR that we use for VMware sitting on a 6030 running 7.2.4 FCP. The aggr is ~ 9TB or so, usable and we have 1 volume that is ~ 5TB or so. We do not currenlty use SMVI (waiting for the budget to open) :) but we will use SMVI and hopefully snapmirror over to another filer. All VM's are windows (for the most part) The primary storage is still on 7.2.4, so no dedupe, or thin provisioning until we upgrade to 7.3.2 sometime this year. This is coming btw to a store near you... Pros/cons to creating smaller/bigger volumes: potentially easier to snapmirror less dedupe % if we create smaller volumes (less vm's, less dedupe) Is there anything wrong with creating 1 volume to 1 aggr and grow the volume to 80%? Am I missing something here? We are thinking of reducing our snap reserve as well. Yes, I have read the vmware best practices doc. VERY GOOD BTW.

Peter, Thanks as always for the information.

The issue has to do with how locks are handled during snapshot commits, and other functionality that uses delta files. The fix has nothing to do with VMware tools. For ESX 3.5 updates 1 and 2, you need to install ESX350-200808401-BG (or a bundle that includes it). For ESX 3.5 Update 3, the patch is already there and you just need to activate it. To activate it, add the following line to /etc/vmware/config prefvmx.consolidateDeleteNFSLocks = "TRUE" and reboot. Details are in TR3428 http://www.netapp.com/us/library/technical-reports/tr-3428.html Enjoy!

And do you have any details about which version of VM tools seems to solve the problem, I thought we were upto date with versions and patches, but still seem to seeing similar problems with smvi and NFS datastores.

The latest theory is that the fixes in the latest version of VMWare tools sorts it out. VMware don't have a firm idea of what's causing it in our environment, but we've seen numerous bugs based on the locking mechanism (which is different in NFS to iSCSI or FC).
