Upgrading from 4.1 to 5.0

SFCFS can be upgraded from 4.1 to 5.0 using phased or full upgrade procedure.

Phased upgrade

Following procedure assumes a 4 node cluster system01, system02, system03, system04 where system01 and system02 are initially upgraded and rest of the cluster is brought up later.

To upgrade from 4.1 to 5.0

1Log in as superuser.

2Select one or more nodes to upgrade, say system01 and system02.

3Insert the appropriate software disc into your system's DVD drive.

4Determine the block device file for the DVD drive:

#ioscan -fnC disk

Make a note of the device file as it applies to your system.

5Create a directory in which to mount the software disc and mount the disc using the appropriate drive name. For example:

#mkdir -p /dvdrom

#/usr/sbin/mount -F cdfs /dev/dsk/c3t2d0 /dvdrom

6Change to the top-level directory on the disc:

#cd /dvdrom

7Install all the prerequisite patches on system01 and system02. See “Required HP-UX patches” on page 15.

If this step is being performed in any phase other than the first phase of the upgrade, the llthosts need to be replace to prevent vxfen from starting after reboot by running the following commands.

a Move /etc/llthosts to /etc/llthosts.bak on all the nodes to be upgraded.
