Hi Emanuel, Shiva is right, we only have volume-online event we dont have volume discovered event like the one for volume-clone:discovered. But adding little logic can help you verify if the volume was discovered or it went offline and came back online. For a volume run this report. dfm report view events-history <volumename-or-id> The oldest event in the chronology for the volume offline is the time when this volume was created. [root@lnx ~]# dfm report view events-history 901 | more Severity Event ID Event Triggered Ack'ed By Ack'ed Deleted By Deleted Source ID Source -------- -------- -------------------------------------------------------------- ------------ --------- ------------ ---------- ------------ --------- ----------------- Normal 9931 Volume Growth Rate OK 28 Jan 14:19 901 SE-Storage2:/vol0 Normal 3075 No Schedule Conflict between snapshot and snapvault schedules 20 Jan 12:59 901 SE-Storage2:/vol0 Normal 3074 No Schedule Conflict between snapshot and SnapMirror schedules 20 Jan 12:59 901 SE-Storage2:/vol0 Normal 3073 Snapshots Age: Normal 20 Jan 12:59 901 SE-Storage2:/vol0 Normal 3072 Snapshots Count: Normal 20 Jan 12:59 901 SE-Storage2:/vol0 Normal 2781 Volume Space Reserve OK 20 Jan 12:50 901 SE-Storage2:/vol0 Normal 2780 Volume Next Snapshot Possible 20 Jan 12:50 901 SE-Storage2:/vol0 Normal 2779 Volume First Snapshot OK 20 Jan 12:50 901 SE-Storage2:/vol0 Normal 2778 Inodes Utilization Normal 20 Jan 12:50 901 SE-Storage2:/vol0 Normal 2777 Volume Space Normal 20 Jan 12:50 901 SE-Storage2:/vol0 Normal 2361 Scheduled Snapshots Enabled 20 Jan 12:48 901 SE-Storage2:/vol0 Normal 2360 Volume Online 20 Jan 12:48 901 SE-Storage2:/vol0 [root@lnx ~]#

Starting, dfm 4.0 the dfm perf view retrieve is changed to dfm perf view2 retrieve so that even though if a custom view is not there for the counter but if you have that counter in any one of the canned views you can still get history data as long as it exist. Now if you create a custom view with that counter and do a dfm perf view2 reterive we show the data that was collected for the canned view dates too. Regards adai

I am not an expert in Crystal Reports, but it should have some way to join two db view. IIRC you can drag columns from two views and create what you need. regards adai

adaikkap · ‎2011-01-27

Hi Siva, The relationship between views and the list of all view and its schema are documented in the man pages, which can be accessed as follows. Control Center-> Help->General Help->Database Schema, Under which you will find the following which should help you in combining two views Database schema for DataFabric Manager nonhistoric data Database schema for DataFabric Manager historic data Relationship among fields of various database views Regards adai

Hi Emmanuel, Pls follow the below FAQ, only if more than 2 things change at a time DFM loses its history of a controller else it won’t. https://now.netapp.com/NOW/knowledge/docs/DFM_win/rel40/html/faq/index.shtml#_9.10 Regards adai

adaikkap · ‎2011-01-24

Yes Shiva is right, it’s a diag counter and you are seeing it because you have enabled the below option. dfm options set perfAdvisorShowDiagCounters=yes Back to Back CP is a label counter and Perf Advisor doesn’t support creating thresholds on label counter. Regards adai

Aggr with most free space. When there is two aggr with equal amount of free space, Then the number of volume per aggr and the number of relationship per aggr are taken into consideration. There is Request to specific the aggr for root volume provisioning of the vFiler. Pls add your case or customer to the Bug. Regards adai

adaikkap · ‎2011-01-18

DFM uses it internal resource selection algorithm in choosing the aggr to provision. User doesn't have control on specific the aggr for the root volume of the vFiler, in vFiler workflow. Though in dataset work flow, you have little control, ie its same as the aggr on which the first data volume is provisioned. Using Manual Resource Selection you can choose in which aggr you want your data volume to be.So in that process the root volume is created on the aggr of the first data volume to be provisioned. Hope it helps. Regards adai

Hi I have not personally tried this on 7.3 so it's possible the behavior has changed to make installing the SV Primary license implicitly enable SV secondary behavior. I think that's quite unlikely. pete you are right, though starting 7.3 both snapvault primary and secondary license call be installed on the same controller(which was not possible until then) you still need license key for SV primary and SV Secondary. Regards adai

Make sure you are not doing active management like a dataset in both DFM server where volume from the same filer is added. You may end up creating or deleting backup version by both DFM server and update too. Similarly you will receive alerts for the same filer from both the DFM server. Regards adai

Its works, but maybe there are cases where it could fail, or cause issue which I may not be aware of. But its better the customer is using a supported solution. Regards adai

NFS works perfectly fine,and can be backed up from any linux or unix host. I havent checked the CIFS shares for backing up from Windows host Regards adai

adaikkap · ‎2011-01-13

Have you checked the below FAQ https://now.netapp.com/NOW/knowledge/docs/DFM_win/rel40/html/faq/index.shtml#_9.10 See if this can help you . Regards adai

adaikkap · ‎2011-01-13

In case of linux you dont have to do anything. But in case of windows,I think it has to be added as a drive, though I might be wrong. May be other experts can correct me. Else I will test and get back to you in couple of days. Regards adai

As far as I know, there is no cli or api to schedule the Top 5 Bar Chart. But if you right click on the chart you can save or print as you wish ? regards adai

adaikkap · ‎2011-01-07

Did you have a look at the below canned report ? [root@lnx ~]# dfm report view volumes-autosize-details Object ID Volume Storage Server Autosize State Maximum Size Increment Size --------- ------------------- --------------------------------- -------------- ------------ -------------- Else this should be possible with the dfm database query run cli from which you can get what you are looking for. Regards adai

adaikkap · ‎2011-01-07

I will look into these burts you mentioned; also we are running 4.0D2 with plans to goto 4.0.1; this should cover the burts ( hopefully ) No.These burts are not fixed in 4.0.1 If i limit a counter group, is it global to all objects in DFM As I said earlier, no as you can see in the cli its setting it perhost. If i limit controllers, can i apply it to groups of controllers ( run the command against a DFM group? ) Yes, attached is the screen shot example from NMC. Regards adai

adaikkap · ‎2011-01-07

I admit that the event would really be useful, but for the mean time you can write a simple script and generate a custom event, that calculates the volume fullness with respect to the Autosize max and not the current total size of the volume. Regards adai

I have a couple of clients that are going to start getting aggressive with triming data; although the monitor.db / log files cannot be changed in size; they are looking at the performance directory and are looking to purge any files / directories over one to two years old. I have been advising against it but i understand their concerns as the perf directory seems to be growing at the rate of 10 GB a month and is pushing against a hard capacity limit on the server. The abnormal growth in perf data, may be due to deleted objects not being purged. You might be a victim of bug 439756.Open a NGS case and clean up. is there a way to control the size of the perf directory? No.But you can control how long you what to retain the perf data for each counter group, and each individual filer using the cli or also the NMC. dfm perf data modify [ -f ] -G <counter-group-name> [ -o <host-name-or-id> ] [ -s <sample-rate> ] [ -r <retention-period> ] Yes we have chatted about moving to a iscsi lun but even that has a limit and even with compression and dedup possibilities ( even all the magic in the world cannot grow 173 GB parition any larger ). The size of their current DFM install is around 120GB right now and in six months i expect the 173 GB disk to be filled. We have reduced the amount of DFM backups to once a day, we have evaluated each monitored controller to see if we really need perf stats collected ... yet the install base grows and grows ( slowly ). will new versions of DFM ( on command, etc ) will introduce hard caps on database growth? No.But did you would like to trim your db get a case open against the bug to see if you can cleanup some history tables. Bug 447658 Regards adai

Mount the CIFS share as a drive in one of the windows box and do a dir to find the list of files. Add those missing file types in dfm using dfm srm file type add command. Regards adai

Is there an Ops Mgr report that can show me how committed the aggregate would be if the SnapMirror volumes guarantees were set to 'volume'? Yes, pls look at this report. aggregates-committed-capacity-report. ....another thought, I'd like to alert via Ops Mgr when the aggregate is committed at 90% (excluding volume autosize calcs). How can I achieve this (without switching autosize off!)? Pls add your case to the bug397557
