SRM with NFS: Important consideration while creating NFS LUN

While implementing SRM with NFS , we have to follow certain guidelines for creating NFS volume on filer or else while configuring array we wont be able to see those volume.
a. Exports must be in the /etc/exports file. Manual exports made with the CLI without the –p option
will not be discovered by SRM.

b. Exports must use values in the RW (read/write) security field in the /etc/exports file. Exports using
the default setting of rw to all hosts will not be discovered by SRM.

Example of a /etc/export line that would be discovered by SRM:

/vol/srm5 -rw=192.168.2.0/24,root=192.168.2.0/24

Example of a /etc/export line that would not be discovered by SRM:
/vol/srm5 -rw,anon=0
So on filer if you run following
Filer101> exportfs -q /vol/nfstest
/vol/nfstest -sec=sys,(ruleid=564),rw=192.168.2.0,root=192.168.2.0
Where as 192.168.2.0 if the vmkernal IP created on Protected ESX host.
