    Yes you do....pretty much do what you did on the first node.  Create users, groups, install software etc.

    Thank u very much for response ,,

     

    During first installation on node1 i chose +DISK1 for ASM SPFILE .

    So when i will start installing ASM and starting instance it will ask me to provide a DISKGROUP(disk) to place ASM SPFILE but i have already used this disk for node1(member of +DISK1 dishgroup of NODE1)

    1.So how this configuration will look like ?

    2.where to place the new spfile of new ASM for node 2

    3.How this new ASM on node 2 will detect the ASM storage and how it will use it ?

    4.When 1st node will b down then who will come to knw that instance should be started on 2nd node and who will do this ?

    Kindly answer.........

    1) Use a small LUN presented to node 2 for the purposes of getting your ASM instance up and running.  You can use ASMCA.

    2) You can have your spfile on this LUN which will be used temporarily.

    3) Define the asm_diskstring and it should pick up the ASM disks.

    4) HACMP needs to be configured with startup scripts etc in the event of instance/node failure.
