SnapMirror to SnapVault or SnapVault to SnapMirror

Hi, I am looking for advice and confirmation as to whether this is possible. Here is our current setup. Primary Site1x FAS8020 - Test_Volume DR Site1x FAS8020 - Test_Volume_sm & Test_Volume_sv The problem we have with the above setup, is that both the sm and sv at DR have Test_Volume at Primary as the source volume so although this works exactly how we want, it means that the source volume data is sent across the WAN twice. The source volume retains minimal data for example, 4 hourly, 4 daily, 4 weekly & 1 monthly. The vault on DR however stores 10 hourly, 31 daily, 5 weekly, 12 monthly. To try and solve the issue of duplicating traffic across the WAN I tried amending the vault relationship so that the source volume was the destination volume for the mirror (Test_Volume_sm). This would then create a snapshot however this would be labelled as snapmirror and would not allow us to have the flexibility in configuring keeping hourly, daily, weekly backups. We could only keep a set number of Snapmirror backups. The original snapshots are created/configured within NetApp VSC 6.0 as it is easier/quicker to restore and we would like to keep it that way. Our reseller confirmed that doing Source-Mirror-Vault allows a snapshot to be created but unfortunatly doesnt follow the naming convention of the VSC snapshots (Hourly, Weekly etc). They did however say that If i amended the setup to perform a SnapMirror of the SnapVault that should work. I am now a bit stuck as I have created my Vault based on the Primary volume being the source volume and this works, retaining snapshots for a longer period of time. Unfortunately (unless i am doing something wrong) I can't seem to be able to snapmirror the snapvault using the snapvault volume as the source because it is a DP volume. I wondered if someone has any ideas/solutions to get the results that we want? Our reseller also said that in ONTAP8.3 SnapVault has been changed so that we can configure our own labels (instead of just sm_created) so our original setup would work however I havent come across this in the release notes???   

OK, I can confirm that in 8.3 you can create SnapVault policy that will transfer only named snapshots from SnapMirror destination. Here is configuration:cluster2::> snapmirror show -fields source-path,destination-path,type,policy

  • Change from SnapMirror to SnapVault

    I have a few LUNs that I'm currently backing up to another filer using SnapMirror. I would like to start archiving these backups with SnapVault. Since SnapMirror works on the volume level and SnapVault works on the qtree level, is there a way to use my existing SnapMirror data or will I need to start from scratch? Can I reuse my existing SnapMirror volume or will I need to create a new one specifically for SnapVault? Does it matter that these LUNs were created and crrently managed by SnapDrive?  Here are my current SnapMirror relationships: NETAPP01:vol10 NETAPP03:na03_vol10 Snapmirrored 00:17:29 Idle
    NETAPP01:vol20 NETAPP03:na03_vol20 Snapmirrored 00:17:29 Idle
    NETAPP01:vol30 NETAPP03:na03_vol30 Snapmirrored 00:17:29 Idle
    NETAPP01:vol40 NETAPP03:na03_vol40 Snapmirrored 00:17:29 Idle  

    You can convert QSM to SnapVault with assistance of technical support, but no such option for VSM.
    BTW, why don't you consider to take and leave snapshot on source volume? If you have enough space for keeping snapshot on source, this is easiest way. VSM covers all the snapshots on source.
    When you need to restore from older snapshot, restoring by snaprestore from source snapshot is first option. If source volume is corrupted, resync from dest then use snaprestore.

  • WAAS and SnapVault/SnapMirror

    Hi,
    We are deploying multiple WAVE appliances with WAAS 4.1.5d.
    The backup solution used is SnapVault/SnapMirror.
    We see the traffic in the WAAS statistics but it is all in pass-through.
    The default setting is used:
    Classifier                -         WAAS Action      - Destination Ports
    Netapp-SnapMirror   -      LZ+TFO+DRE      - 10565-10569
    Has anyone seen this issue before?
    How do I troubleshoot such a thing

    In the output of the sh stat conn CLI command, there is a column titled "ConnType".  For the connections you are seeing in pass-through, what is the ConnType listed?

  • SNMP OIDs support in Netapp c-mode

    Hi,I have been new to netapp devices. I have been working on a system which monitors the netapp devices. Till 7-mode my software monitors the netapp devices well. However after we have started working with c-mode devices we are encountering some problems:1. When we do snmpwalk for ndmp OIDs, it returns error: This may be that the OIDs(1.3.6.1.4.1.789.1.1.4.x) are not implemented on c-mode devices however at below link "http://people.teamix.net/~bu/81ClusterModeCLReference/CLI-Commands-NetApp-81-Cluster-Mode.pdf" I have seen that CLI exists.2. Simillar issue I am observing with snapvault, nfs, cifs and snapmirror OIDs.Do somebody have any idea about this or can somebody share any reason fro the above?Is there any document or some link where I can find the information?Thanks in advance.

    I can add to this, working on this same issue now.  We had a customer move from a FAS3020 in 7-mode to a 8020 in c-mode.  Monitoring was working previously for the global status but since the cutover nagios was reporting OID not found. I was able to pull the MIB from the device by going to t http(s)://cluster-mgmt-ip/spi and downloading it.  I imported this into a MIB browser and located the misc global status OID which is 1.3.6.1.4.1.789.1.2.2.4.0 however a snmpget to the cluster (both nodes and the VIP) results in a response of: Error in packet
    Reason: (noSuchName) There is no such variable name in this MIB.
    Failed object: .1.3.6.1.4.1.789.1.2.2.4.0 It's almost as if the filer has no idea that the OID exists.  In fact I did a SNMPWALK on the device and output that to a file and don't find that OID at all.  In fact there appears to be nothing under the .2 identifier yet it's listed in the MIB. (1.3.6.1.4.1.789.1.2.2) What gives?  How do you measure anything in the misc category per the MIB as they are all 1.3.6.1.4.1.789.1.2.2.x.x?  This is Ontap 8.3 btw. Any help on this would be appreciated. Thanks!

    Hi Gerald,
    I would recommend downloading the Early Adopter release of the Oracle SQL Developer Migration Workbench - http://www.oracle.com/technology/tech/migration/workbench/index_sqldev_omwb.html -, to carry out the database migration of your MS Access database. This is a new, redeveloped tool that extends the functionality and usability offered by the original Oracle Migration Workbench. The early adopter is only available for SQL Developer 1.1 Patch 2. In SQL Developer, ensure that you follow the instructions to "Check for Updates". This will add the Migration Workbench and the MS Access extension, required to migrate your MS Access database.
    I hope this helps.

  • OSSV realationship

    I had ossv running on a windows 2003 box for a few months, then the site admin decided to uninstall the ossv software. Now after re-installing I cannot get the windows machine to snapvault. When I do a snapvault status on the Windows machine there are no destinations defined. I am new to this product and was wondering if this can be easily repaired. BTW we are using DFM.

    I am not an expert on OSSV, You can try these steps and see if it helps your situation.The Open Systems SnapVault database consists of a set of files that contain information about the Open Systems SnapVault relationship between a primary and a secondary storage system.OSSV agent database backup file :
    The database files for an Open Systems SnapVault relationship on the primary storage system are compressed and backed up as a file named .OSSV_DATABASE_BACKUP. If a file named .OSSV_DATABASE_BACKUP already exists in the directory being backed up, the second and subsequent files to be created follow the naming convention .OSSV_DATABASE_BACKUP_x, where x is an integer used to uniquely identify each file.Restore (OSSV agent database ):
    You can restore the database file by using the snapvault restore command; however, you must include the file name .OSSV_DATABASE_BACKUP in the command.
    Example:
    To restore the database from a secondary storage system called f840 to a directory \temp\database on the primary storage system, enter the following command:D:\Program Files\netapp\snapvault\bin>snapvault restore - S f840:/vol/vol0/rel5/.OSSV_DATABASE_BACKUP D:\temp\database
    Resynchronize:
    Starting with Open Systems SnapVault 2.2, you can use the snapvault start -r command to resynchronize a relationship without having to reinitialize it.1  Log in to the secondary storage system.
    2  On the console, enter the following command to resynchronize a SnapVault relationship:filer>snapvault start -r -S prim_host:dirpath /vol/sec_vol/sec_tree
    filer>snapvault start -r -S melzhost:C:\melzdir /vol/sv_vol/tree_melzhttps://library.netapp.com/ecmdocs/ECMM1278863/html/install/manage3.htm

  • Convert SnapMirror XDP to DP

    Hello Community.  I want to convert a XDP extended data protection relationship into DP, because I will shorten the update frequency and XDP doe not finish within timeframe.  Waht I tried was:1. Snapmirror break2. Snapmirror delete3. snapmirror create with type DP and DPdefault4. Snapmirror resync --> But at step four I got "Error: command failed: No common Snapshot copy found between..." When I looked into the volume I could found lot of snapshots that were available on both volumes.  Is it possible?Why I can't resync? greetings Frank

    Convention from XDP to DP is not supported.
    Each volume seems to have common snapshot, but it is just common for SnapVault. Not common for DP as data have transferred in file basis and block image do both side is completely different. DP tracks and updates data in block basis, so XDP snapshots does not work for resyncing.

  • SnapCreator 4.1.1 GUI error when adding SnapVault configuration

    Hi All, I am hitting a GUI error issue when executing new configuration wizard in SC 4.1.1 Basically the error shows up when SC is trying to get a list of existing SnapVault relationships in order to verify them. This results in volumes not being properly marked as source and destination. Beforehand, I am able to discover vservers and reach out to volumes - SCFM_test on source cluster and SCFM_test_DP as destination. There's an existing SV relationship initialized between them. Please find all corresponding logs attached. I will be grateful for any hints. Ontap is cDOT 8.2.1

    Hello there
    What others have gone to is quite interesting and explains the reason why you got such an output from your code.
    But to overcome the problem I suggest using the following code in your program.
    for (int i = 0 ; i < 10; i++) {
              System.out.println(i + "\t" + ((double)Math.round(10*a))/10 + "\t");
              a += 0.1;
    No, that's a useless approach.
    If the issue is just the display, then use a Formatter or DecimalFormat when displaying. If the issue is that you actually want fixed decimal precision, then use BigDecimal.Well, the issue indicated in the original post was displaying. So provided that we understand the reason why the original code worked in that way, I suggested the simplest approach to display the desired series!

  • Performance issue with snapmirror and snapshots on target aggregate

    Hi all, does anyone of you has experience with snapmirror an larger amount of data. At the moment we do a snapmirror of about 100tb data distributed over about 10 volumes to a sata aggreagate on a second filer with 85 4tb sata disks (5x17disk raidgroup). Source is FAS 8040, target is FAS 8020 both with cdot 8.3p1. We already moved all workload from the target aggregate, so it hosts only snapmirror targets.On the source side we do 1 snapshot per day and keep 14 snapshots. Snapmirror is done once per day. From counting snapshots  I would say daily change rate is 2-2,5tb for all volumes. Snapmirror is working fine and finished in less than 2-3h, but container block reclamation and deswizzling is totally killing the aggregate on the target side. We do see continous load of 30MB read and disk util for all disks except parity disks is 90-100%. At first we planned 4h snapshot but that is just not possible. At the moment we disabled deswizzle and get to a point where if we are lucky the target aggregate load drops in the night just before next snapmirror kicks in. We are quite new to Netapp but it sounds ridiciolous, that you need so much io for just a plain replication and some snaps.Do you have any experience with snapshots and snapmirror using sata disks? I think snapshots and snapmirror on Netapp are very resource demanding. It is true that the creation of snapshots on Netapp is super efficient and instant but as soon as snapshot has to be deleted container block reclamation kicks in and takes large amount of disk resource. Same for snapmirror, it is really cool and stable, but deswizzling for logical to physical block mapping with large data affects snapmirror target performance heavily.  Best wishes, Stefan  

    Hi RPHELANIN, schedule is 24h. Yes from time to time dezwizzle does not finish, but 24h is our max, we planned with 4h. But I think this is just impossible with nl-sas disks unless you do not change data on source :-). We crossed checked deswizzle and container block reclamation with disabling each of them. Most of the load is produced by container block reclamation.The positive impact of flashcache is on deswizzle lower than on container block reclamation. I think most of NetApps internal workload is sized for 10k and 15k drives. If we compare io per gb of 10k 900gb drive with 7k 4tb drive we have a ratio of nearly 10:1. Mechanics like reclaim blocks or map virtual to physical blocks seem to produce to much load for nl-sas drives. On the othe hand deduplication and compression works fine and produces acceptable disk load. Nevertheless we disabled it cause it produces to much changed blocks for snapmirror.  Best wishes, Stefan

  • OSSV snapVault : compatible with Windows 2012 native deduplication ?

  • Snapmirror over fc in cluster mode ?

    I just found the doc for 7-mode.does snapmirror over fc support in cluster mode ? Thanks

    No it did not carry forward into cDOT. 

  • Snapmirror: What kind of checksum does it use and is there a way to manually verify it?

    Two questions:
    1. I have been searching but unable to find what kind of checksum snapmirror uses to verify its copies. Can anyone tell me? If there is a technical document explaining it, that would be perfect.
    2. Is there a way to manually verify, or display the checksum verification, of a recent snapmirror? Or manually run the checksum verification between the source and destination volumes without having to mount them to, say, a linux server and run an MD5 on them?Reason im asking is that I have some executives that are using an application and its data is now the most important thing to this company...more important than the environment itself. They are asking for this data to be copied from one place to another and then a visual verification of some kind showing that the two match, every 30 days. I say Snapmirror because i know it uses a checksum verification and there we have the copy and the verification in one. I can tell them that if the checksum fails, we will get an email alert that the snapmirror failed. But they want the visual "yes" every time, instead of the silence of a "yes" and a loud "no."

  • SnapVault destination larger than source

    I am currently using snapvault to backup volumes offsite. I have dedupe enabled on both source and destination volumes and I can see that dedupe is running after the snapvault transfer. I have a 1TB volume as the source that has both hourly and daily snapvault snapshots inside of it using about 66% of the volume. I am transferring just the daily snapvaults to the destination which is also the same size and that volume is 94% used. I do not have the default snapshots turned on, nor do I have a fractional reserve or snap reserve on the destination. Anyone have any ideas why the destination is using so much more than the source? These are CIFS volumes.  Thank you in advance. 

    On the destination, there is one snapshot that stands out more than all the others. I currently have 12 dailes on the destination. The snapshot labeled sv_daily.7 is 310 GB while all other snapshots are under 800MB. On the source there is nothign glaring at all. The largest snapshot is 7GB.  There are 3 or 4 others that are a couple GB and the rest a few hundred MB.
