# ./ocrconfig -add +GRID_NNNN2
PROT-30: The Oracle Cluster Registry location to be added is not usable

While looking file directory ,we see there is allocation for file number 255.

 

$ grep F00000255 GRID_NNNN2.map
N0001 D0000 R00 A00000357 F00000255 I1 E00000000 U00 C00001 S0001 B0101871616 

But asm level file number 255 was not visible.

Due to async IO issue at ASMlib ,IOs were not completing .
