Image access options
Hello,
I have a customer replicating Linux LUNs. When accessing the LUNs on the target host, the volume group automatically gets imported and LUNs are automatically mounted in a similar fashion to the source. This would normally be desirable, but this customer wants to just have the LUNs presented when enabling image access and nothing else.
Just wondering how to achieve this. My first though is that RP probably does this based on the host OS selected during consistency group creation. So if I select "other" for OS, will it not know that these are Linux LUNs and then just present them without creating the volume group, etc.?
No Events found!

Hi Shah,
RecoverPoint replicates the data and the underlying filesystem/LVM structures on conjunction with the Host OS policy setting. Therefore, if you simply mount the filesystems from the OS after enabling image access, the data will be presented in the LVM structure as per the source volumes.
The LVM structure can be managed/manipulated from the OS once the CG is in image access mode as this allows R/W access to the volumes at the OS. If you change the Host OS setting to another policy setting the LVM structure may not be maintained and the data on the volumes may be unrecognizable.
Regards,
Richard
