NFS HA Service Group in VCS 5.x on Solaris 10

Remember to delete the service maps for NFS using svccfg command

With Solaris 10 and VCS 5.x, nfsd HAS TO run under VCS control. In order to achieve that, the following needs ton happen (on every node that will host the NFS share) —

Disable/Delete the NFS services from SMF

# svccfg delete -f svc:/network/nfs/server:default
# svccfg delete -f svc:/network/nfs/status:default
# svccfg delete -f svc:/network/nfs/nlockmgr:default

Manually restart lockd, statd and automountd

# /usr/lib/nfs/lockd
# /usr/lib/nfs/statd
# /usr/lib/fs/autofs/automount
# /usr/lib/autofs/automountd

NOTE: In this example (see below), the NFSgrp is configured only for one node. To add another node, add the node name and number to SystemList and AutoStartList

       group NFSgrp (
               SystemList = { hostA = 0 }
               AutoStartList = { hostA }
        )

        DiskGroup nfsDG (
               Critical = 0
               DiskGroup = testdg
        )

        Volume nfsVOL (
              Critical = 0
              Volume = testnfshome
              DiskGroup = testdg
        )


        IP IPres (
                Device = bge0
               Address = "10.10.10.22"
                NetMask = "255.255.255.0"
        )
        Mount Mountres (
                MountPoint = "/nfs/testnfs"
                BlockDevice = "/dev/vx/dsk/testdg/testnfshome"
                FSType = vxfs
                MountOpt = rw
                FsckOpt = "-y"
        )
        NFS NFSres (
                Nservers = 16
        )

        NFSLock NFSLockres (
                PathName = "/nfs/testnfs"
        )
        NIC NICres (
                Device = bge0
        )
        Share Shareres (
                PathName = "/nfs/testnfs"
                Options = "-o rw -d \"test home dirs\""
        )
