RMAN error

ORA-27054: NFS file system where the file is created or resides is not mounted with correct options
Additional information: 2

I am using an NFS share for RMAN backups. After mounting the file system and trying testing a backup using RMAN I received the ORA-27054 error. This is due to the fact that mount was not established correctly. The following is the correct syntax for mounting NFS for RMAN to utilize. Since I am mounting two server versions of Solaris; 5.8 and 5.10 to the same NFS share.

Oracle 10gR2 on UNIX,

For SUN Solaris 5.8 sparc 64 or Solaris 5.9
mount rw,bg,intr, hard,timeo=600, wsize=32768, rsize=32768

Actual entry (all one line) in the vfstab file (where bigshare is the server):
bigshare:/export/oracle - /oracle_backups nfs - yes rw,bg,intr,hard,timeo=600,wsize=32768,rsize=32768

For Solaris 5.10 use
mount -F nfs -o hard, bg,proto=tcp, vers=3, suid, rsize=32768, wsize=32768, intr,noac

Actual entry (all one line) in the vfstab file (where bigshare is the server):
bigshare:/export/oracle - /oracle_backups nfs - yes hard, bg,proto=tcp, vers=3, suid, rsize=32768, wsize=32768, intr,noac
