[ClusterLabs] Migrating cluster node from SLES11 for SAP sp2 to sp3

[Cristiano Coltro]

Hi All,
A customer of mine is searching the smmothest way to migrate an envinronment SLES for SAP 11 sp2 to SLES for SAP 11 sp3.
What they want to do is to add a new SLES for SAP 11 sp3 X remove the old SLES for SAP 11 sp2 from the cluster. This will be done one by the other: a new came in an old goes out.

This obviously imply the fact that for a certain period of time ( I would suggest not too long...) SLES11 for SAP sp2 and SLES11 for SAP sp3 will exist in the same cluster.

Is that a supported condition considering also the characteristics of the environments described below?

SLES 11 for SAP sp2
-kernel 3.0.101-0.35-default,
xita185u:~ # rpm -qa | egrep "sbd|crm|openais|corosync"
corosync-1.4.7-0.19.6
libcorosync4-1.4.7-0.19.6
openais-1.1.4-5.19.7
libopenais3-1.1.4-5.19.7
sbd-1.2.1-0.7.22
crmsh-1.2.6-0.35.11

SLES 11 for SAP sp3
-kernel 3.0.101-0.47.55-default.
newxita185u:~ # rpm -qa | egrep "sbd|crm|openais|corosync"
corosync-1.4.7-0.21.3
libcorosync4-1.4.7-0.21.3
openais-1.1.4-5.22.1.7
libopenais3-1.1.4-5.22.1.7
sbd-1.2.1-0.7.22
crmsh-1.2.6-0.38.1.17

The support is intnended for the modules and for this kind of plug/unplug.

Any help appreciated.

Thanks
Cristiano
