you are not talking about the VCM device are you ? It's a small device ..should be around couple of megabytes.

No, none of the devices are VCM devices

PowerPath has been loaded and licensed ?

Yes powerpath is loded, licenced and all the paths are good.

can you make sure that device is not write_disabled or not_ready ?

hmm ..looks like somebody deleted previous posts. What does this device look like in Disk Management ?

Disk is looking like normal disk but when tried to initialize it is failing.

The devices are in ready state, all the paths are alive.

can you post output from "symdev show -sid DEV#" , remove serial number of your array.

The fallowing is the output for this device

looks ok. Anything in common that you can see between these devices that can not be initialized ?

Everything is same and OK, devices which can't be intialized and whch are intialized all have the same properties.
BCV host group is making any problem in here? I doubt.....

nah ..BCVs are in split state. Just for giggles ..can you unmask/unmap these "troublesome" devices and map them to a different address on FA ?

Yup That that is what exactly we have in our mind, this should work, but we are more concerned about to find why this happened.

Hello JaiHo and welcome to the forums
I have moved your question from the Powerlink lite forum into the PowerPath forum now that you have access to all of the forums as a customer.
Please let me know dynamox if this is not the correct place for it.
