DP Transfer Mirror Reports

Hi all,

I'm hoping somebody can clear something up for me.  We manage 96 filers, all of which are monitored by Oncommand Unified Manager/DFM.  We have a lot of snapmirrors from remote sites back to larger filers at our main data centers which appear as External relationships and don't appear in DP Transfer Mirror reports.

Recently though we have deployed 3 FAS2220 filers configured the same as the previous 85 FAS2040 filers and those snapmirrors DO appear in the DP Transfer Mirror Reports.  I have checked licensing and options and haven't found any significant differences between the filers.  All are running Ontap 8.1.2p4 and are licensed for Protection Manager and operations manager.

Any ideas?  I'm stumped.

Thanks!

Re: DP Transfer Mirror Reports

Hi,

  1. What version of OCUM that you are running ?
  2. What is the value of this option ?
  3. Are both source and destination controllers of the SnapMirror managed by OCUM ?
  4. When you say snapmirror are they, volume snapmirror relationships or qtree snapmirror ?

Can you give an example of the relationship being discovered and reported by OCUM, but transfer report for the same is not being shown ?

dfpm relationship list | grep <some relationship name>

dfm report view <transfer report> | grep <same relationship name>

Re: DP Transfer Mirror Reports

Hi Adai, thanks for the reply.  Below is the information you requested.

  1. OCUM version is 5.2
  2. Not sure which option you mean
  3. For the FAS2040 filers, none of the snapmirrors are managed by OCUM/Protection Manager.  In other words, the snapmirror relationships existed prior to us implementing OCUM show as external relationships in OCUM/NMC, have not been imported into a dataset and are managed by the snapmirror.conf file. All filers are monitored by OCUM.
  4. All the snapmirrors are VSMs.

Re: DP Transfer Mirror Reports

Hi

    BTW was this a fresh install of OCUM 5.2 ?

Pls check whats the value of this option

lnx142-x2:~ # dfm option list dataTransferReports

Option              Value

------------------- ------------------------------

dataTransferReports Disabled

lnx142-x2:~ #

If its disabled, pls enable the same to get the datatrasnfer reports.

Re: DP Transfer Mirror Reports

We have been running DCFM/OCUM for a couple year now and have upgraded the original installation along the way up to 5.2.

PS C:\> dfm option list dataTransferReports

Option              Value

------------------- ------------------------------

dataTransferReports Enabled

Re: DP Transfer Mirror Reports

Hi,

      You have all things that are required for datatransfer report. So at this time are out of ideas as to why you aren't getting the transfer reports for the VSM relationship that are discovered in OCUM.

In order to show up the transfer reports, the relationship just needs to be monitored in OCUM and not necessarily managed.

My first gut feel is may be due to the naming, as the hostname and the volume names both have the same, FAS2040, but that's my gut feel.

I suggest you open a case with Netapp Support for more deeper investigation...and there by for a resolution.
