braack, When you are having latency issues, what does your device queue look like? I am curious how large your DQLEN is and how high your %USD gets during high load for the iSCSI LUN. Then under high...

VMware only supports a single datastore on a disk/LUN, so this might be the reason that the SSD doen't show up as an available device. André

Hi,I was svmotion'ing a MSCS VM with RDMs today(the RDM were migrated separately from the SAN side) and after the migration I figured out that the VM moved with the vmdk files only. The .vmx files ,...

Have you made sure that there is no .vmx and log files in the new datastore? Confirm that before doing anything,

Can you do svMotion to the old and back to new one? Something's gone wrong the first time. Manually moving the files might be tricky. Not that it can't be done.

Be very careful about cold migration this will effectively convert your RDM to VMDK during the process, see here for more details VMware KB: Migrating virtual machines with Raw Device Mappings (RDMs)...

Ruhul, you can perform svmotion without removing the RDM luns and while the VM is online. This will only move the pRMD pointers. Just to be on the safe side make sure the node you are working is the...

That is my understanding of it, if you are running 5.X you can migrate online and use the advanced option. But here is another good article Migrating RDMs, and a question for RDM Users. | VMware...
