Can I use "kfed repair" when dg is mounted ?

Hello

I met following symptom.

+ Mounting Diskgroup Fails With ORA-15063 and V$ASM_DISK Shows PROVISIONED (Doc ID 1487443.1)

# kfed read /dev/mapper/data1

==

kfdhdb.acdb.aba.blk:                  0 ; 0x1d8: 0x00000000
kfdhdb.acdb.ents:                     0 ; 0x1dc: 0x0000
kfdhdb.acdb.ub2spare:             43605 ; 0x1de: 0xaa55  <============================

But, relating disk group is still mounted.
