Set up a NAS volume or a qtree.
Make the directories of the mount points. However, do not make a directory or a file under the directory of the mount point. The mount control with PRIMECLUSTER cannot be done when there is a directory or a file under the directory of the mount point.
Set the mount point in /etc/vfstab.pcl.
<NetApp Filer(7-Mode) or ETERNUS DX is used> #RMS#<NAS host name:NAS volume or qtree name> - <mount point> nfs - no <option>
<NetApp Filer(cDOT) is used> #RMS#<NAS host name(for the data access):NAS volume or qtree name> - <mount point> nfs - no <option>
For standby operation using NAS device with IPv4 address, the following option is recommended:
rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,forcedirectio,vers=3
For scalable operation using NAS device with IPv4 address, the following option is recommended:
rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,noac,vers=3
For standby operation using NAS device with IPv6 address, the following option is recommended:
rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp6,forcedirectio,vers=3
For scalable operation using NAS device with IPv6 address, the following option is recommended:
rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp6,noac,vers=3
Example
<Standby operation using NAS device with IPv4 address case> #RMS#netapp1:/vol/vol1 - /mountpoint1 nfs - no rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,forcedirectio,vers=3
<Standby operation using NAS device with IPv6 address case> #RMS#netapp1:/vol/vol1 - /mountpoint1 nfs - no rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,forcedirectio,vers=3
Information
forcedirectio option avoids cache data erasing if the server goes down.
