How To Create ASM Diskgroups using NFS/NAS Files

ASM is completely supported on NAS (e.g. NFS filesystem on NetApps).
步骤如下:
1) As Oracle OS user, create the disk devices on your NFS directory:
oracle>dd if=/dev/zero of=/oracle/asm/disks/nfsdisk2 bs=8192 count=100000
100000+0 records in
100000+0 records out
oracle>dd if=/dev/zero of=/oracle/asm/disks/nfsdisk1 bs=8192 count=100000
100000+0 records in
100000+0 records out
oracle>ls -l
total 3201600
-rw-r--r-- 1 oracle dba 819200000 Aug 11 14:10 nfsdisk1
-rw-r--r-- 1 oracle dba 819200000 Aug 11 14:09 nfsdisk2
2) Connect to your ASM instance and set the NFS directory in the discovery path:
SQL> alter system set asm_diskstring = '/oracle/asm/disks/*' scope=both;
System altered.
SQL> show parameter asm
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
asm_diskgroups string
asm_diskstring string /oracle/asm/disks/*
asm_power_limit integer 11
Note: If spfile is not being used then you will need to update the pfile (init+ASM.ora) with the next values to preserve the changes during the shutdown/startup:
asm_diskstring = '/oracle/asm/disks/*'
Where: “/oracle/asm/disks/*” is the NFS directory associated with the NAS disk devices.
3) Verify the NFS disks are now discovered thru the v$asm_disk view:
SQL> select path from v$asm_disk;
PATH
----------------------------------------------------
/oracle/asm/disks/nfsdisk1
/oracle/asm/disks/nfsdisk2
4) Finally, create the diskgroup on the NFS disks:
SQL> create diskgroup test external redundancy disk
'/oracle/asm/disks/nfsdisk1',
'/oracle/asm/disks/nfsdisk2';
Diskgroup created.
