While you can get this on Windows using VSS, I wonder how can you even possibly achieve this on Linux (unless using something like LVM snapshots or similar). On NetApp this depends on scope of atomicity. You get atomic snapshot of all data on a volume using NetApp snapshots. This presents you with data as existed at the time snapshot was created. I guess it is as close to you requirement as it can be. If you need completely atomic snapshot across all data - I do not believe you ever had this before. ... View more

Well, you just plug in your shelves into switch ports and the assign disks as usual. If ports are not yet configured, you have to do it as described in MetroCluster installation guide or switches configuration guide. I prefer to configure all ports initially, when setting up MetroCluster, this is also recommended in MetroCluster TR. I do not think you will find step by step guide specifically for this task. ...

You can do takeover/giveback instead of reboot. For FCP/iSCSI/NFS it should be fully transparent (of course there are other considerations like PAM rewarming). ... View more

please note that the cluster should be disabled while you reboot. Why? It is enough to do takeover/giveback for the head where root volume is being moved. This way it can be done non-disruptively. ... View more

You have to options. Reinstall one head. Shut it down, reassign disks from other head, start installation procedure on the remaining ones. As you have no user data, could be an option. Convert two RAID_DP into RAID4 which gives you 2 spare disks. Assign them to the head, create new aggregate and move root volume to it. Then destroy old root aggregate and redistribute disks as needed. Convert back to RAID_DP when finally done. May be easier as it does not require to redo all settings. ... View more

I have seen 0.5, 2 and 5 meters. As I understand, it depends on whether this is configured as the first or subsequent shelf (i.e. whether this is controller-to-shelf or shelf-to-shelf). I must admit I have not used NetApp quoting tool for ages, so I do not know whether this is possible to explicitly select cable length when quoting shelf. But you always should be able to add additional cables as single parts. ... View more

Performance advisor (part of Operations Manager) can do it. There are (now web-based) tools that would produce pretty graphs from performance archives or perfstat results, available to NetApp employees or partners; you could ask your NetApp representative to help with it. Finally, there are free solutions based on widely available monitoring tools like Cacti or Nagios; you will need to spend some time to set them up and collect data (although it is possible to preload RRD tables with historical data using some script magic). But if you have performance issues, it makes sense to open call with NetApp anyway, ... View more

SystemManager does not “convert volume to LUN”. It creates LUN on volume, which is entirely different thing. It could be intelligent enough to recognize existing share on volume and to not offer it for LUN creation according to best practices (do not mix files and LUNs on the same volume). ... View more

Data ONTAP 8.1 also allows you to do VSM from 32 to 64 aggregates which converts them to 64 bit on destination. SnapMirror will preserve FLexClone space savings (there are some manual steps necessary to setup it). ... View more

After system is installed, the only thing that is done is to initialize root volume. The volume itself is empty. Boot device is not touched either (for 7.x). Before doing reboot you have to do standard software update followed by download. This installs boot files onto root volume and transfers them onto boot media (CF). You can use any of the available methods, e.g. HTTP. ... View more

If management cards are proprely configured, the takeover is automatic during MetroCluster rack power failure As long as LAN switches do not suffer from the same power outage (e.g., do not located in the same rack ) Also, if network goes down at the same time, an UPS solution Well, it is unrealistic to expect to protect against all possible permutaitons of component failures between two sites. It has to start with NetApp offering management port redundancy in the first place Finally, if MetroCluster is used with "complicated" inter-links (like DWDM), a third referee could be used (like Tie Breaker) and NetApp provides some solutions like this. MteroCluster TieBreaker solution is no more supported to the extent, that some user who posted here old TR referring to it was requested to remove it. It was replaced by Microsoft only SCOM plugin and now by MSCS plugin which is Microsoft only again. What can we offer to Unix only customer? And yes, I have Unix only customers and they would like to have automated failover (I will leave aside discussion whether automated failover in any long distance solution makes sense at all) ...
