Looking at the FAS32XX Installation and Setup instructions ( http://now.netapp.com/NOW/knowledge/docs/hardware/filer/210-04848+A0.pdf ) It seems that c0a and c0b are for cluster interconnect. I only see e0a and e0b (1g ether) for NAS traffic. It also says that c0a and c0b could be copper or fiber. I'd guess that you do stretch MC with fibre connects, I'd guess that with fibre for interconnect you could do stretch MC, but it's just a guess... I hope this response has been helpful to you.

Hoping the /etc/exports file will still have all of your old export definitions. If you're using an NFS adminhost you'll have to delete the current /etc/exports file before you copy the old one out of the snapshot directory. Easier to copy it out of the .snapshot directory than to do a snaprestore. You can do a volume snaprestore on vol0, which will initiate a reboot of the filer. It would also revert you back to the expired NFS license. I wouldn't want to do that... I hope this response has been helpful to you. At your service, Eugene E.

I'm not sure I understand how you would have so many local groups ? There's a distinct difference between local groups/users and domain users/goups. Local groups for CIFS are defined in the /etc/lclgroups.cfg file. They can contain domain and local users. Domain groups are defined in AD. In most cases Robo or other tools will sync your ACLs for you. I hope this response has been helpful to you. At your service, Eugene E.

Yes, SANscreen is very cool. It can do a lot more than determine firmware versions ! It is, however, an expensive enterprise product. Most clients do not have SANscreen. The HUK has 'sanlun' which may give firmware versions. I'd rather look at the drivers in ESX with hardware provider tools. I hope this response has been helpful to you. At your service, Eugene E.

Looks like a disk ownership issue. Did you get the right disks/shelves separated ? Boot and hit ctrl-C when it says to get the boot menu.

Scott - Welcome to the community ! Rules ? What rules ? : ) Be polite when you post ? I've had writing a blog post on the 'rules' here on my agenda for a while, it will be coming Real Soon Now. Networker has implemented the NDMP protocol, but it is currently not clear to me how much command and control can be done. See also: http://www.ndmp.org/ A recent post asked whether it could initiate a SnapMirror to tape operation. I'm pretty sure it will not, but haven't gotten a hold of the documentation for an emphatic answer. At the very least it will do a ufs dump and restore of NetApp data.

Luis - See the output for 'snapmirror status'. Err, much to be aware of with Metrocluster, keep reading. ( It's not always the same nets, read about mcrc file network configs. ) I don't understand your qustions about syncmirror, but yes, you can break and re-establish mirrors by taking plexs offline, and re-mirroring.

Sanman - My motivation for keeping application data on seperate volumes is to segregate it for rates of change and snapshots.

All - All of this talk about implementing commodity hardware with ZFS or otherwise on this forum is crap. We've taken a look at provisioning our lab environments on ZFS and std hardware at Labshots/Kashpureff Inc and already found that a WAFL/NVRAM architecture beats it out any day. Wish I could post our performance test, but I can't. Performance is a broader subject than CPU ratings. What do you do with that CPU power ? How much bandwidth can you drive on the front end and the back end ? ONTAP has always been exceedingly good at doing what it does (serving up storage) using commodity hardware, and it continues to be highly optimized. ( Have you read 'How to Castrate a Bull ) ? Dave first tested this OS on commodity PCs. It's a software company, not a hardware company. The controllers rock, but WAFL, snapshots and nowadays OnCommand - that's the value proposition here. I'll invite any of the detractors here to take the time that we have to do implementation performance tests and then go tell their bosses that they should implement a cheap solution from one of the vendors trying to sell $9K jbod storage on ZFS or another solution. Bad news - It will be an RGE - Resume Generating Event. Just my two bits.

Welcome to the NetApp community ! From the SMVI Install and Admin Guide, under 'Adding a vCenter server': Note: You can only connect to one vCenter Server.

I learn new things every day - It's why I love my job. From the 'Data ONTAP System administrtion Guide': (Which most often bores me = it's sooo old hat.) System Performance and Resources -> How to Increase WAFL cache memory It describes that the sysstat cache age is the age of blocks swapped out of cache. I always described it as the average age of objects in cache. There is a distinct diference, due to the intelligent cache algorithm used in ONTAP. It changes, over time based on many factors, (nearstore, FlexShare, PAM) Best guess I gave studfent - 's' might mean 'system' buffers aged out of cache. But sometimes the documentatikn can be thin 'round here. Is there someone from engineering who might clarify for us ? I hope this response has been helpful to you, others, and to Terry.
