From the linux server:

wget http://oracle.3dub.com/iscsi-ls
chmod 755 iscsi-ls
./iscsi-ls

  • tmpfs needs to be expanded: /etc/fstab put size=4G in place of ‘default’ for the tmpfs. This is necessary to get isci to start! I beat myself up for 2 days on this :(
  • openfiler host/netmask is somewhat misleading. Use the EXACT rac nodes IP addresses and the netmask 255.255.255.255 (specifying the host explicitly).
  • ocfs2 rpms need to match ‘uname -a’ exactly or it wil NOT work. It will install without warning, but will NOT work.
  • iscsi-ls is not available for RHEL5. You can run ocfs2console and it will show you the scsi ID on the local machine that the disks are attached to. You can then mount them manually.
  • java not installed to /usr/local/java/bin, but at /bin/java/jre/1.4.2_06/bin so I had to symlink like so
    cd /usr/local
    mkdir java
    cd java
    ln -s /bin/java/jre/1.4.2_06/bin
  • vipca and srvctl have a wierd bug where it uses LS_ASSUME_KERNEL. They need to be commented out as explained in http://cs.felk.cvut.cz/10gr2/relnotes.102/b15659/toc.htm#CJABAIIF

    you will need to change the following line if you use dual NIC’s (as in the case of our RAC systems) in /usr/etc/upsd.conf

    LISTEN localhost
