Creating a new NFS resource group in Sun Cluster 3.2

1. Make sure the new LUN’s are visible and available to be configured.

     # echo | format > format.b4

     # scdidadm -L > scdidadm.b4

     # cfgadm -c configure <controller(s)>

     # devfsadm

     # scdidadm -r

     # scgdevs ( on one node )

     # scdidadm -L > scdidadm.after

     # diff scdidadm.b4 scdidadm.after

Note down the new DID devices. This is to be used to create file systems

2. Create the new metaset

        # metaset -s sap-set -a -h phys-host1 phys-host2

3. Add disks to metaset

    # metaset -s sap-set -a /dev/did/rdsk/d34

    # metaset -s sap-set -a /dev/did/rdsk/d35

    # metaset -s sap-set -a /dev/did/rdsk/d36

    # metaset -s sap-set -a /dev/did/rdsk/d37

4.  Take ownership of metaset on phys-host1

          # cldg switch -n phys-host1 sap-set

5. Create new volumes for sap-set

    # metainit -s sap-set d134 -p /dev/did/dsk/d34s0 1g
    # metainit -s sap-set d135 -p /dev/did/dsk/d34s0 all
    # metainit -s sap-set d136 -p /dev/did/dsk/d35s0 all
    # metainit -s sap-set d137 -p /dev/did/dsk/d36s0 all
    # metainit -s sap-set d138 -p /dev/did/dsk/d37s0 all

6. Create new filesystems

    # umask 022
    # newfs /dev/md/sap-set/rdsk/d134
    # newfs /dev/md/sap-set/rdsk/d135
    # newfs /dev/md/sap-set/rdsk/d136
    # newfs /dev/md/sap-set/rdsk/d137
    # newfs /dev/md/sap-set/rdsk/d138

7. create new mount points, Create it on both the nodes.

    #mkdir -p /sap; chown sap:sap /sap

    #mkdir -p /sapdata/sap11 ; chown sap:sap /sapdata/sap11
    #mkdir -p /sapdata/sap12 ; chown sap:sap /sapdata/sap12
    #mkdir -p /sapdata/sap13 ; chown sap:sap /sapdata/sap13
    #mkdir -p /sapdata/sap14 ; chown sap:sap /sapdata/sap14

8. Edit the /etc/vfstab file and add the new file systems.  Make the mount at boot option as “no”

9. Create the Resource group SAP-RG.

      # clrg create -n phys-host1 phys-host2 SAP-RG

10. Create logical hostname resource.

      # clrslh create -g SAP-RG saplh-rs

11. Create the HAstoragePlus Resource

       # clrs create -t HAStoragePlus -g SAP-RG -p AffinityOn=true -p FilesystemMountPoints=”/sap,/sapdata/sap11,/sapdata/sap12,/sapdata/sap13/sapdata/sap14″  sap-data-res

12. Bring the Resource Group Online

    # clrg online -M phys-host1 SAP-RG

13. Test the failover of the Resource Group

     # clrg switch -n phys-host2 SAP-RG

14. Failover Back

     # clrg switch -n phys-host1 SAP-RG

15. Create the SUNW.nfs Config Directory on the /sap file system.

     # mkdir -p /sap/nfs/SUNW.nfs

16. Create the dfstab file to share the file systems

    # vi /sap/nfs/SUNW.nfs/dfstab-sap-nfs-res

    #share -F nfs -o rw /sapdata/sap11
    #share -F nfs -o rw /sapdata/sap12
    #share -F nfs -o rw /sapdata/sap13
    #share -F nfs -o rw /sapdata/sap14

17. Offline the SAP-RG resource group.

      # clrg offline SAP-RG

18. Modify the Pathprefix variable to ensure that NFS knows path to cluster dfstab

    # clrs set -p Pathprefix=/sap/nfs

19. Bring the Resource Group online

    # clrg online -n phys-host1 SAP-RG

20. Create the NFS resource in SAP-RG resource group.

    # clrs create -g SAP-RG -t nfs -p Resource_dependencies=sap-data-res sap-nfs-res

21. Resource should be created and enabled as part of SAP-RG

    # clrs status

22. check to see if the server is exporting filesystems

    # dfshares
