Have execute the command symdev -sid <> write_disable ?
I am unable to write disable the newly created srdf r2 device. when  i try to disable the write for the r2 device it produces the erorr stating the device already in the requested state, however actually status of the device is RW enabled. there will be any impact  if the r2 device in R/W sate?
