I apologize for dropping this at the front porch. I don't see the storage group.

I am trying to migrate active LUNs between 2 FS9150s.

These FS storage are linked partners using IP connection(s). I am able to create consistency group and relationships between the 2 storages, they are now consistent copy for all volumes.

I am reading this link IBM Flash system Non-Disruptive Upgrade (NDU) using Nondisruptive volume migration between systems.

wich shows the migration methodology, however between a generic SV1 and a FS9500.

The host beign migrated is running SuSE 15 SP3. When I try to use the LVM to handle the active/passive paths the kenel turns the filesystem to R/O in an attempt to protect the data.

Bottomline, the method in the link works up to the point where the OS "supposes" to handle the multipath automagically. But it does not.

I'll appreciate all your comments
