11GR2: Create multipath disks

Hello,

We have a 2 node rac.    Version : 11.2.0.4     ,  OS  :  RHEL 6.7   Storage netapp.

Our sysadmin , has created a multipath disk and handed it over to dba's to add it to existing diskgroup.       This is the multipath information

/dev/mapper/crbprd_data_fcoe6

sdas 66:192  0  250G  0 disk

└─crbprd_data_fcoe6 (dm-14)   253:14   0  250G  0 mpath

sdat 66:208  0  250G  0 disk

└─crbprd_data_fcoe6 (dm-14)   253:14   0  250G  0 mpath

sdau 66:224  0  250G  0 disk

└─crbprd_data_fcoe6 (dm-14)   253:14   0  250G  0 mpath

sdav 66:240  0  250G  0 disk

└─crbprd_data_fcoe6 (dm-14)   253:14   0  250G  0 mpath

Should we do the following on multipath disks so that header information is updated

/usr/sbin/oracleasm createdisk DATA6 /dev/sdas

/usr/sbin/oracleasm createdisk DATA6 /dev/sdat
