  YEs that is fine as it will be done after clusterware is installed manually 
if not invoked by Clusterware installed as there is bug due to IP addresses. My 
concern is to get information about the Bonding  and multipathing. I am 
searching for some information on Google and I appreciate if you have any link 
and advice on this setup.

Subject: Oracle RAC private Interconnect
   
    It is recommended to use two Gigabit Switches for RAC Node Interconnect 
communication to provide Redundancy and performance. Is there any setup 
required on beside configuring two interface like eth1 and eth2 and then 
specifying them in RAC cluster installation PRIVATE Interconnect screen.

     

    I am just trying to understand that how the failover or redundancy is 
achieved if I unplug one of the Cable on one Node. Is it been configured by RAC 
clusterware or I had to tell something to sysadmin.

     

    Also how performance is achieved in using two Switches.

     

    I am currently having 10g RAC on sun SOlaris 10 with one Gigabit Switch for 
QA environment and planning for Production hardware requirements.

     

    Also If I use Oracle 10g ASM for Storage and RAW device for OCR and Voting 
Disk. I am using EMC with Two SAN switches and so  2HBA on each Node. Anybody 
has any doc for Multipathing with EMC. My concern is that both nodes see the 
RAW Device LUN as well as ASM luns as same and two HBA should provide the high 
availability when I will remove one of the HBA

     

     

    Thanks

    Sanjay
