cfsmount(1M).
19 Run step 7, step 9, and step 16 on rest of the nodes to be upgraded.
Full upgrade
Following procedure assumes a 4 node cluster system01, system02, system03,
system04 where all nodes are simultaneously upgraded from 4.1 to 5.0.
1 Log in as superuser.
2 Insert the appropriate software disc into your system's DVD drive.
3 Determine the block device file for the DVD drive:
# ioscan -fnC disk
Make a note of the device file as it applies to your system.
4 Create 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
5 Change to the top-level directory on the disc:
# cd /dvdrom
6 Install all the prerequisite patches on all the nodes. See “Required HP-UX
patches” on page 15.
7 Offline all SFCFS resources on all nodes by running the following
commands on one of the cluster nodes.
# hagrp -offline service_group -sys system01
# hagrp -offline service_group -sys system02
# hagrp -offline service_group -sys system03
# hagrp -offline service_group -sys system04
where service_group is the command that displays the service groups by
hagrp -dep cvm.
