InfoScale™ 9.0 Storage Foundation Cluster File System High Availability Configuration and Upgrade Guide - AIX

To upgrade the operating system

1. Rename the /etc/llttab file to prevent LLT from starting automatically when the node starts:

   # mv /etc/llttab /etc/llttab.save

2. Create install-db file to prevent VxVM daemons or processes from starting automatically when the node starts.

   # touch /etc/vx/reconfig.d/state.d/install-db 

3. Upgrade the operating system on all nodes in the cluster.

   For instructions, see the operating system documentation.

4. If you upgraded the operating system, restart the nodes if required:

   # shutdown -r now

5. After the system restarts, rename the /etc/llttab file to its original name:

   # mv /etc/llttab.save /etc/llttab

6. Enable VxVM to start after system restarts.

   # rm /etc/vx/reconfig.d/state.d/install-db

To perform the upgrade

1. Log in as superuser.
2. Insert the appropriate media disc into your system's DVD-ROM drive.
3. If volume management software is running on your system, the software disc automatically mounts as /mnt/cdrom.

   If volume management software is not available to mount the CD-ROM, you must mount it manually, enter:

   # mkdir -p /mnt/cdrom
   # mount -V cdrfs -o ro /dev/cd0 /mnt/cdrom

4. Change to the top-level directory on the disc:

   # cd /mnt/cdrom

5. Verify there are no VxFS file systems mounted on the nodes being upgraded:

   # mount | grep vxfs

6. Unconfigure the lmx module on all nodes in the cluster.

   # /etc/init.d/lmx.rc stop

7. Start the upgrade from any node in the cluster. Enter the following command, and then press y to upgrade the cluster configuration.

   # ./installer -upgrade

8. You are prompted to enter the system names (in the following example, "sys1" and "sys2") on which the software is to be upgraded. Enter the system name or names and then press Return.

   Enter the system names separated by spaces: 
   [q, ?] sys1 sys2

9. During the initial system check, the installer verifies that communication between systems has been set up.

   If the installer hangs or asks for a login password, you have the option to let the installer configure SSH or RSH communications between the systems. If you choose to allow this configuration, select the communication type and provide the root passwords for each system.

10. At the prompt, specify whether you accept the terms of the End User License Agreement (EULA).

    Do you agree with the terms of the End User License Agreement
    as specified in the EULA/en/EULA_ENTERPRISE_Ux_9.0.pdf file 
    present on media? [y,n,q,?] y

11. The installer displays the following question before the installer stops the product processes if the current cluster is secured and version is prior to 6.2.:

    • Do you want to grant read access to everyone? [y,n,q,?]

      • To grant read access to all authenticated users, type y.

      • To grant usergroup specific permissions, type n.

    • Do you want to provide any usergroups that you would like to grant read access?[y,n,q,?]

      • To specify usergroups and grant them read access, type y

      • To grant read access only to root users, type n. The installer grants read access read access to the root users.

    Note:

    Separate the usergroup names with spaces. To grant read access to a usergroup on a specific node, specify usergroup as <usergroup>@<node_name>. You can also specify usergroups here and create them later.
