Can not create Dynamic group in Volume Replicator.

This issue has been solved. See solution.

Hi,

We have the below details.

1. Server OS - MS Windows 2008 Ent. R2.

2. Application - Oracle

3. Drive Details - C: D: E: (All are in the same Drive where the C drive ).

4. Network Bandwidh - 10 Gbps granated.

5. License Details - a. VRTS STORAGE FOUNDATION 6.0 WIN FOR OS TIER STANDARD EDITION PER SERVER STD LIC EXPRESS BAND S

                              b. VRTS STORAGE FOUNDATION OPTION VOLUME REPLICATOR 6.0 WIN FOR OS TIER STANDARD EDITION PER SERVER    STD   LIC EXPRESS BAND S

 

We have installed the VVR software on both the end.

When trying  to provide the license its giving me the error that license is not support in Windows Ent. R2 server .

We have installed with "keyless" license option.

We have tried to create a dynamic group in the disk but its givien me the error that it can not create a dymanic group with the same disk where C: partition is there (rather system partition).

We have created the dynamic group with the option "Microsoft Managment ..." option. It did created but unable to create the "Replication Data Set".

when creating the RDS its showing me the error that ...

"Error V-108-273-24 Could not find the Dynamic Disk Group. Please make sure the current version of the Dynamic Disk Group is imported. Note that VVR does not support Windows Disk Managment compatible disk group."

 

Please, help me of this above issue.

I am very much new to VVR.

Thanks.

As the message says "VVR does not support Windows Disk Managment compatible disk group" - it has to use a dynamic diskgroup and as it says in the error you got you can not create a dymanic group with the same disk where C: partition is.

So for VVR you need a separate LUN (which windows sees as a Harddisk - you cannot use a parition of a harddisk) to create a dynamic diskgroup in which you will create you data volume(s) and the SRL volume (and DCM bitmaps which are created automatically when you create RDS, but this requires you leave a few MBs free in your diskgroup when you create the volumes).

The LUN for VVR can come from a SAN or can be internel to the server.  So for example, if the single disk presented to you server is provided by some RAID manager, you need to get the RAID manager to present at least 2 disks to the system (so you have Hardisk0 and Harddisk1) - one for your O/S and one for VVR, but this reorganisation will probably trash the current data on the disk, so you will then have to reinstall the O/S.

Hi,

There is no storage LUN for theses server ...the disk is the local one(native) with RAID array...

There is single array where c drive and other driver is residing...

As you said..

"The LUN for VVR can come from a SAN or can be internal to the server.  So for example, if the single disk presented to you server is provided by some RAID manager, you need to get the RAID manager to present at least 2 disks to the system (so you have Hardisk0 and Harddisk1) - one for your O/S and one for VVR, but this reorganization will probably trash the current data on the disk, so you will then have to reinstall the O/S....."

We need to recreated the RAID ...and this will make the whole server to rebuild...blush

Is there Any other way...

As we have another server where VVR 5 is installed with same RAID configuration..

And the C Drive and other Drive were in the same Disk (same Disk0)...There the replication is happening...

There only Drive D is replicated... and I have seen the Dynamic Disk Group there its having only the volume which need to replicate..

Is there any VVR version issue (i.e. it can be possible in VVR 5 now in VVR 6 it's not possible).

Thanks.

Edit ... I have found a discussion with a solution that does match with my scenario....

My understanding is that this is not possible and Wally is more of an expert on Windows than I am (I do UNIX and Windows and UNIX is more my expertise) and in the thread you mentioned Wally says it is not possible in VVR 5 for the same reasons as I outlined above.  So I don't understand how you got it to work on another system - is the Dynamic Disk Group on this server a Windows Compatible disk group or a SFW dynamic disk group - can you provide output from this working system of:

vxdisk list
vxdg -g dg_name dginfo  (you can get dg_name from above command or "vxdg list")
vxprint
