How to Install and Configure varital cluster ( SFHA) for NFS-Part-2

                       Configuration of VCS(SFHA) for NFS

 Installation starting 

after Installation complated restart the servers.

1. Initialize disks

# vxdisk -e list or vxdisk -eo alldgs list (check on both)

bringing the disk into veritas control 

[root@vcsnode1 ~]# /etc/vx/bin/vxdisksetup -i disk_0

[root@vcsnode1 ~]# /etc/vx/bin/vxdisksetup -i disk_1

[root@vcsnode1 ~]# /etc/vx/bin/vxdisksetup -i disk_2

# vxdisk -e list  (output should be same on both node)

2. Create disk group nfsdg01

# vxdg -o coordinator=on init nfsdg01 disk_0

# vxdg -g vcsgp set coordinator=off

# vxdg -g vcsgp adddisk disk_1

# vxdg -g vcsgp adddisk disk_2

# vxdg -g vcsdp set coordinator=on

Error

ERROR V-5-1-12061 adddisk not permitted on coordinator dg: vcsgp

Solution

vxdg -g vcsgp set coordinator=off

3. Checking the connectivity policy on a shared disk group

[root@vcsnode1 ~]#  vxdg list vcsgp

1. Create logical volume 

 [root@vcsnode1 ~]# vxassist -g vcsdg make vcsvol01 2G

[root@vcsnode1 ~]#   vxprint 

[root@vcsnode1 ~]#  vxprint –l  <volume_name>    #To print details of volume which you create

2. Create file system

    [root@vcsnode1 ~]# mkfs.vxfs /dev/vx/dsk/vcsgp/vcsvol01

3. Make local directory on both nodes vcsnide1 & vcsnode2

[root@vcsnode1 ~]#  mkdir  -p /vcsshare01  /vcsshare02

[root@vcsnode1 ~]#  mkdir /vcslock

[root@vcsnode1 ~]# chomd 777 /vcsshare01

[root@vcsnode1 ~]# chomd 777 /vcsshare01

root@vcsnode1 ~]# chomd 777 /vcslock

[root@vcsnode1 ~]# mount -t vxfs /dev/vx/dsk/vcsgp/vcsvol01 /vcsshare01

[root@vcsnode1 ~]# mount -t vxfs /dev/vx/dsk/vcsgp/vcsvol02 /vcsshare02

[root@vcsnode1 ~]# df –h #check status

4. Unmount 

[root@vcsnode1 ~]# umount /vcsshare01

[root@vcsnode1 ~]# umount /vcsshare02

5. Install the nfs server on both nodes 

Note: no need to start the NFS service veritas will handle it. Stop the NFS service on OS level
