INQ performs some SCSI commands that look for storage that has been presented to the host. The INQ can only show what the host sees. This is not necessarily what has been provisioned. Have you rebooted the host? Have you checked the ready and read write state of the devices?

No Jasonc, its a production server we don't have downtime to reboot, yes deivices are read/write state. the question when we got request  from server team to remove few devices we have removed successfully after that they are not able to see all the devices , before they see, is there any command sothat we can view in diskmgmt ( devices are not visible in diskmgmt) I checked at array side devices are exist in storage group. I don't know what would be the reason why the devices are not visible only in diskmgmt.
