Err, You're very welcome. Don't think it's up to BURT level, but they could make the issue clearer in the docs. I have to have guys label SAS and ACP interfaces for client installs - LOL ? On the deeper dive - I think even without ACP the different shelf loops will fall back to using the data path for control messages if there is no ACP installed.

There's an internal target date, but no public release yet. I have no indication that 32 to 64 bit aggregate conversion will be a feature. My clients are waiting on SnapLock Compliance certification.

Proactively ? What's your definition of proactive ? It implies you do things to prevent a cluster failover. Make sure you maintain your NetApp. Keep it cool, provide clean power, the list could go on. Enabling autosupport to notify you of health events, watching out for BURTS regarding your equipment, using SNMP traps and monitoring are all good proactive practices. But an autosupport message to notify you of a cluster failover is the primary way to know that it happened. I hope this response has been helpful to you. At your service, Eugene E.

Ouch ! The only way to reset the root password is through the boot menu. (press CTRL-C when prompted during the kernel boot) This is a console operation. Do you have termserver access to the console ? Given that you can't log in to halt the filer, you'd have to power cycle to re-boot. You'd want to shut down all hosts using the filer to do this as cleanly as possible. (or trust in cluster failover when you power cycle the head) You may do it remotely through the RLM, if you still have the RLM password... I hope this response has been helpful to you.

I haven't been posting for a while, but have been lurking in the background... Back to basics here. Can you ping the host you are trying to use http from ? ( and vice versa ? ) What is the environ for your sim ... a VM ? Is it a 7.X or an 8.X sim ? There are many posts here on communities that you may search to find the answers, but we love a 'Beginner' 'round here, and there are many to try and answer your questions. We were all a 'NetApp Beginner' at one time. For DOT 7.X sims on Linux hosts be sure that 'promiscuous mode' is enabled on the VM switch... ( This is the most common problem, sim is listening in prom mode, like a packet sniffer ) I hope this response has been helpful to you ... At your service, Eugene E.

You may want to. How many data disks did you have before the addition ? What is the resulting RAID layout ? You cna run 'reallocate measure' on a volume or two on the aggregate - look for a 'hot spots' index number.

sstidham34 - Welcome to the Communities.NetApp.com ! Did you turn on 'options fpolicy.enable on' ? fpolicy.enable When turned off, this disables all file policies on the filer, overriding the settings for individual file policies. When turned on, the setting of a given file policy determines if that file policy is enabled or disabled. (It doesn't list the default, and I'm not logged on to any filers) I hope this response has been helpful to you. At your service, Eugene E.

Jean - Welcome to the NetApp Communties site ! It never stops to amaze me how dear old posts from the past return here. I would have thought that something like cifs latency would have at least been in the MIB. But I spent some time this evening going through v 2.0.3 - and there's nothing in there I can see to set a poll for or trap trigger for: http://now.netapp.com/NOW/download/tools/mib/ I didn't even see volume latency ? Though, we can see this from stats ... Are we missing something here or should somebody be beatin ass on the SNMP team at NetApp ? Of course, there's the API.. I didn't take the time to do the dive again into the Ops Mgr docs or try to do a model in the labs this time... Maybe I wil tmrw. : } I hope this response has been helpful to you.

Are you trying to audit the file access, monitor disk space usage, or bandwidth ? All three can be done with Data ONTAP. To file access see the 'cifs.audit' family of option settings, and the 'cifs audit' command. For disk space usage see the 'quota' command and the /etc/quotas configuration file. To monitor bandwidth usage see the 'cifs top' command with 'options cifs.per_client_stats.enable'. Be aware that this can be a performance hit - you don't want to leave cifs.per_client_stats.enable turned on. I hope this response has been helpful to you. At your service, Eugene E.

See the definition for the 'igroup remove' command: igroup remove [ -f ] initiator_group node ... Removes node (s) from an initiator group. You may use the alias for the node , set with the fcp wwpnalias command. The operation is prohibited if there are existing LUN maps defined for that group. The -f option can be used to force node removal. Looks like you may be able to do it with good ol' '-f' for force flag. I hope this response has been helpful to you. At your service, Eugene E.

SIOC would help if you're pounding on any given data store from a number of ESX hosts. SIOC won't kick in until you start getting greater than the trigger latency on a given LUN/data store.

Brendan - Makes perfect sense to me. Thank you for the reference to 'options disk.maint_center.spares_check'. Wish we had an option to enable scan of non-zeroed disk automagic ... With the smaller deployments disk utilization versus available disks has always been one of those edge subjects to me. What do you do when you've only got six disks for your side of the cluster ? I'd like to see more discussion regarding best practice and smaller installations. My preference is against a dedicated aggr0/vol0 - but I still see it deployed as best practice...

Brendan - I wasn't aware of this limitation to the maint center cycle. Can you point us at a quick reference ? Thank you in advance. SAS drives are in general more reliable than SATA, as are FC.

Downside is if you ever run out of space when thin provisioning. Bad things happen if you run out of space ! But yes, you can and ( I say ) you should thin provision. It'd be a very good thing to have a thorough understanding of thin provisioning in a NetApp SAN environ before doing so.

Mark - Welcome to the NetApp community ! I'm sure there's folks here to shed light on your problems... Do you have your NOW.netapp.com access ? http://now.netapp.com/NOW/public/knowledge/docs/hardware/filer/210-03951.pdf Have you found the documentation pages on filerview ? ( http://myfiler/na_admin ) You're correct that you're running with no spares on at least one filer, but if you see 'partner' disks you've got a cluster. There's another head for you to log onto and check out. How many disks total do you have ? How many aggregates ? If you've got a dparity disks you could go down to RAID4, but I wouldn't want to.
