snapmirror on vsim

[anujt]

Am trying to setup and verify snapmirror across 2 vsims, but seeing below issue.

Any help/guidance shall be of great help to identify what am I missing here?

Issue seen –

Snapmirror is not working across 2 different  vsims

Error says – Snapmirror expects that the destination filer to be same as that of source filer

--Error snip—

smoke6-vsim-pbc7b6g*> snapmirror initialize -S smoke6-vsim-pbc7b6g:vol3 -w smoke6-vsim-pbc7b6h:vol3

Illegal destination filer specification: smoke6-vsim-pbc7b6h.

Destination filer, if specified, must match the local host: smoke6-vsim-pbc7b6g.

usage:

snapmirror initialize [-k <n>][-s <src_snap>][-c <dst_snap>][-S [<srcfiler>:]<srcpath>][-w] [<dstfiler>:]<dstpath>

Big Thanks!

Hi Anuj ,

Try to edit the conf file as 

smoke6-vsim-pbc7b6g:vol3 smoke6-vsim-pbc7b6h:vol3 - * * * * *

Then run initialize  command

thanks

Hi Ashwani,

Thanks for your response.

But this has not helped. Same problem still exists.

Regards,

Anuj

Anuj,

     Did you change the serial number of one of the sims?  The simulators have identical serial numbers and this breaks things like VSM on the sims until you change one of them to have a different serial number.

Hi Scott,

Thanks for your inputs.

But I have not changed serial nos on the devices.

I verified that both the devices have different serial nos.

Hi Anuj ,

Check last two things  1)  if snapmirror is licensed on destination . 2) if you are able to ping destination filer ip from the source .

[anujt]

Hello Ashwani,

Yes I verified that snapmirror is licensed on both source and destination.

And I am able to ping the destination filer from the source.

Hi Anuj  ,

Can you please share vol status and vol option for the destination volume .

Hi Anuj ,

The fractional reserve is 100 ?     please remove this .  Restrict the volume once again  .Ensure the size of destination volume is => source volume  .Run the   > snapmirror initialize  -S   srcvolume destinationfiler:destinationvolume

[anujt]

Hi Ashwani,

Is fractional reserve the same as snap reserve?

If not - please guide how to modify it ?

[ASHWANI8HIGHS]

Hi  ,

One thing I missed that is your source volume has fractional reserve set to 100 .Please check if that is set to 100 then its fine to have on destination volume . Yes fractional reserve is different then snap reserve . Fractional reserve is used in SAN volumes to ensure space reservation for lun

[cscott · Accepted solution]

Anuj,

     I cannot believe I missed this before:

smoke6-vsim-pbc7b6g*> snapmirror initialize -S smoke6-vsim-pbc7b6g:vol3 -w smoke6-vsim-pbc7b6h:vol3

You should be initializing from the destination.

Log into smoke6-vsim-pbc7b6h and run snapmirror initialize -S smoke6-vsim-pbc7b6g:vol3 smoke6-vsim-pbc7b6h:vol3

Initialize should be run from the destination filer.

100% Scott   You refresh some snapmirror fundamentals
