AIX mount NFS, I believe that many inexperienced people do not know what to do, so this article summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

AIX mounts NFS for RMAN backup

# mount nfsserver:/share / mnt/nfs

Mount: giving up on:

Nfsserver:/share

Vmount: Not owner

After looking up the information, it is found that the Linux operating system needs to use this NFS reserved port when responding to mount requests from the AIX operating system, which is not open by default.

# nfso-o nfs_use_reserved_ports=1

Setting nfs_use_reserved_ports to 1

Mount for RMAN backup

Mount-v nfs-o rw,bg,hard,nointr,rsize=32768,wsize=32768,vers=3,timeo=600,proto=tcp 10.32.200.129:/data/dmp / data/dump

Use umount / sapbackup/orabak directly and prompt "umount: device is busy". If you use the following command to uninstall (under Linux, you usually use fuser-km / mnt/cdrom to query the currently used process and kill)

Umount command under AIX:

Fuser-kxuc / sapbackup/orabak

Umount / sapbackup/orabak # if you uninstall but prompt that the device is in use, you can use the umount-f parameter

If RMAN backup is reported to ORA-27054, you need to do the following

ORA-19504: failed to create file "/ data/dump/CIQINDX_1.dbf"

ORA-27054: NFS file system where the file is created or resides is not mounted with correct options

Additional information: 6

Error reference:

Say BUG, check noac against NFS, but it is not necessary. Fix at 11.2.0.1, or turn off the validation.

ALTER SYSTEM SET EVENTS '10298 trace name context forever, level 32'

Then RMAN can back up.
