PRIMECLUSTER Wizard for NAS Configuration and Administration Guide 4.2 - Solairs(TM) Operating System -

2.4.1 /etc/vfstab setup

Define mounting of the NAS volume or qtree in /etc/vfstab as follows:

#RMS# NAS host name: NAS volume name or qtree name - mount point nfs - no option

• For standby operation, the following option is recommended:

  rw,bg,hard,intr,proto=tcp,forcedirectio,vers=3

  
  
• For scalable operation, the following option is recommended:

  rw,bg,hard,intr,proto=tcp,forcedirectio,noac,vers=3

#RMS#netapp:/vol/vol1 - /NAS nfs - no rw,bg,hard,intr,proto=tcp,forcedirectio,noac,vers=3
#RMS#netapp:/vol/vol2/data - /DATA nfs - no rw,bg,hard,intr,proto=tcp,forcedirectio,noac,vers=3

forcedirectio option avoids cache data erasing if the server goes down.

• For NAS host names, the same names that are registered in DNS or /etc/inet/hosts must be specified. If IP addresses are used, the NFS locking might not properly be controlled.
• Any directory must not be created under a mount point that is specified in /etc/vfstab. If a directory exists, mounting might not properly be controlled on PRIMECLUSTER.
