Is there a must to insatll the Disaster Recovery Manager in DFM to get the snapmirror alerts?

[tatlee]

The user wants to monitor the snapmirror information, especially if the snapmirror lag time is breached. Is there a must to use DRM to monitor, or is there other ways to create the alert?

Cheers!

That is my understanding.

I have created a bat file which I run from my pc which passes the command

rsh %FILER01% -l %RSHPERM% "snapmirror status filer:volume" >>c:\Logfiles\%COMPUTERNAME%_SnapMirrorList.txt

and just repeat for every snapmirror.

We also use MOM and have used the NetApp SDK to use VBS to poll the snapmirrors witch have 15 minute updates.

Hope this helps

Hi Brendon,

Thanks...But how to get the alert when the lag time is over, that means the sanpmirror is not working properly. Also, is there able to get an email alert when this happen? Otherwise, the user will not know until the check on the messages.

Cheers!

Terrence.

Snapmirror status monitoring requires BCO or Protection Manager license.

You can use the dfm run command to run commands on filers.And get the snapmirror status and use script plugin to generate

custom events and generate alarms.

If you have any of the license mentioned, Then you can get the snapmirror lag warning and error evet for all filers monitored by dfm.

by default snapmirrorLagWarningThreshold is 1.5 days,

snapmirrorLagErrorThreshold is 2.0 days.

which can be changed.

Adaikkappan,

Thanks....Will let the customer to buy the license then.

Hi,

The Protection Manager and Protection Manager DR licenses are installed, but still cannot get the snapmirror lag alarms. There were several snapmirrors having a lag time for more than 4 weeks, but didn't get the alarms. Any idea?

I have attached the screenshots.

Hi  Lee,

     Ops-Mgr monitoring snapmirror generates an event for the relationships like this for lag.

[root@lnx]# dfm eventtype list -C sm.lag
Event Name                                         Severity     Class
-------------------------------------------------- ------------ ------------------
snapmirror:date-ok                            Normal       sm.lag
snapmirror:deleted                            Information  sm.lag
snapmirror:nearly-out-of-date                 Warning      sm.lag
snapmirror:out-of-date                        Error        sm.lag
[root@]#

What you are showing is the PA threshold, I dont thing so both are same.

AFAIK That threshold is for the counter value and has nothing to do with the snapmirror lag that you have attached.

Can you try creating an alert in Ops-Mgr for this event i mentioned above and see you get the event.

Regards

Hi Adai,

I have created the snapmirror:nearly-out of-date and snapmirror:out-of-date alarms in DFM long time ago, but still cannot get the alerts.
