Migrate Packages - service guard

[Fernando Jose P de Souz]

Hi,

I'll migrate my packages to new servers and new cluster.

I create the procedure.

cmhaltpkg p1
vgexport -m /etc/cmcluster/mapavgp1 -s -p -v /dev/vgp1
cmhaltcl -v
rcp between the servers
vgimport -m /etc/cmcluster/mapavgp1 -s -v
vgchange, mount e IP
Test Oracle DB
umount, vgchange e IP
cmquerycl -v -C /etc/cmcluster/cmclconf.ascii -n hpxjf55 -n hpxjf65
cmcheckconf -v -C /etc/cmcluster/cmclconf.ascii Verificar o arquivo /etc/cmcluster/cmclconf.ascii
cmapplyconf -v -C /etc/cmcluster/cmclconf.ascii cmmakepkg -p /etc/cmcluster/p1/p1.conf
Copy the packages files the old packages to new cluster and start packages
cmcheckconf -C /etc/cmcluster/cmclconf.ascii -P /etc/cmcluster/p1/p1.conf
cmapplyconf -C /etc/cmcluster/cmclconf.ascii -P /etc/cmcluster/p1/p1.conf
cmrunpkg -n hpxjf55 p1

Shalom,

Nice procedure.

To actually do this with minimal downtime, the nodes intended for the new cluster are going to have to join the old one.

ON OLD CLUSTER:
# cmhaltpkg
For each VG in the package:
# vgexport -pvs -m /dev/
# vgchange -c n
# rcp *.map NEW_CLUSTER_NODE_A:/etc/lvmconf/
# rcp -pr /etc/cmcluster/ NEW_CLUSTER_NODE_A:/etc/cmcluster

ON NEW CLUSTER NODE_A:
Connect the disk array to the new cluster

# rm /etc/cmcluster//*log
# rcp -pr /etc/cmcluster/ NEW_CLUSTER_NODE_B:/etc/cmcluster

For each VG in the package, do the following on each node in the new cluster:
# mkdir /dev/
# mknod /dev//group c 64 0xUU0000 <<-- where UU is a unique minor number
# vgimport -vs -m /etc/lvmconf/.map /dev/

Insure at least 2 active networks or 1 network and 1 standby NIC are configured.
Build the cluster:
cmquerycl -v -C /etc/cmcluster/cmclconf.ascii -n hpxjf55 -n hpxjf65
vgchange -a y
cmapplyconf -v -C /etc/cmcluster/cmclconf.ascii
vgchange -a n

For each new package:
cmapplyconf -P / -f

It's Ok.

The procedure is ok.

Thanks.
