Hello,

I did offline HACMP(PowerHA) upgrade 5.4.1 to 5.5 - basically stopped HACMP services and upgraded cluster.* filesets.
Tried to start services again - topsvcs refused to start on second node complaining that node instance numbers are different - and indeed they are different.

This is standard situation or something went wrong ?
What should I do - make instance numbers identical manually ?

thanks,
Vilius

Might this fix IZ14738 apply to your problem? See the following link for details:

IBM IZ14738: INSTANCE NUMBER DISCREPANCY LEADS TO PARTITIONED CLUSTER

I hope this helps.

can't tell you what went wrong, every topology sync should increment all node instance numbers by one

this is how you change them:

Code:

odmget HACMPtopsvcs | tee file.txt

HACMPtopsvcs:
        hbInterval = 1
        fibrillateCount = 4
        runFixedPri = 1
        fixedPriLevel = 38
        tsLogLength = 5000
        gsLogLength = 5000
        instanceNum = 8

change the instancenumber on the standby node to the instancenumber of the primary node, and use odmchange to update this information


but I can't tell you about other consequences this might have, so backup your odm first



side note: in Power HA 7.1 instance numbers are always one, since topsvcs is not being used any longer
