Step-by-Step Cluster Conversion
HP-UX Configuration
Chapter 3 119
# remove everything that is different from DVEBMGS<INSTNR>,
ls
# Example: rm -r SYS
# rm -r D00
cd DVEBMGS<INSTNR>
find . -depth -print|cpio -pd /usr/sap/<SID>/DVEBMGS<INSTNR>
rm -r * # be careful with this
cd ..
rmdir DVEBMGS<INSTNR>
2. Mark all shared volume groups as members of the cluster. This only
works if the cluster services are already available. For example:
cd /
# umount all logical volumes of the volume group
vgchange -a n <vg_name>
vgchange -c y <vg_name>
vgchange -a e <vg_name>
# remount the logical volumes
3. The device minor numbers must be different from all device minor
numbers gathered on the other hosts. Verify this by comparing numbers
listed in Table 1-3 Hosts and Device Minor Numbers to the numbers
listed in the tables contained in chapter 2.
Create map files with the vgexport command and distribute them to all
nodes in the cluster for all shared volume groups.
