I'm used to seeing raw disks/devices inside ASM diskgroups, but at my new
contracting gig, they have a Netapp storage appliance, and are using nfs
mounted luns.  What they've done in the ASM Diskgroups is have actual .asm
files that show up in a filesystem mounted on the OS. (see below for a
"picture" of what I'm talking about).

This is my question:  How would these .asm files be getting created?  (I'll
need to know this when I need to add space to an existing disk group)

ASM_DISKGROUP= DATA_GROUP

The "disks" inside this disk group are:
/prod_dbName_data/asmData/nfs_data_dbName_01.asm
/prod_dbName_data/asmData/nfs_data_dbName_02.asm
/prod_dbName_data/asmData/nfs_data_dbName_03.asm
/prod_dbName_data/asmData/nfs_data_dbName_04.asm
/prod_dbName_data/asmData/nfs_data_dbName_05.asm
/prod_dbName_data/asmData/nfs_data_dbName_06.asm
/prod_dbName_data/asmData/nfs_data_dbName_07.asm
/prod_dbName_data/asmData/nfs_data_dbName_08.asm

/prod_dbName_data/asmData is a filesystem on the OS.

Thanks for any insights (and apologies if this is a seemingly simple
question :)

Regards,
Chris
