We are working on NetApp (AFF300 7.6P5) with Redhat enterprise Linux 7.7 with DM-Multipahing. We plan to mirror local device to NetApp with Linux native LVM. Then use NetApp to replicate the volume to remote site for a DR application server. But we encountered some issues. Can somebody share your experience?
1). First of all, we couldn't make the DM-Multipath working properly with NetApp. We created a multipath.conf for NetApp, we did see NetApp multipath device but looks the device is unstable (path down and up), we doubt the multipath.conf is not set up correctly, can someone share yours as example?
On the multipath.conf, we have to change the product value to "LUN" for vendor "(LSI|NETAPP)" to see the LUN, not sure if it is correct.
the individual device is accessible and stable, i assume we are having issue on multipath device.
2. we plan to use local device (SSD) as primary copy, then use LVM mirroring to make second copy to NetApp LUN. Replicate the Netapp volume to different location. is that a good practice?
