AIX

Hi All,

Is multibos really needed on each sp update on a hacmp config?

Is someone using it?

I have an up coming update and I don't have time to understand this technology. Does SP update might screw you up and you can't restore properly from it?

Thanks for any idea in advance.

HACMP 4.5 is not supported with AIX 5.3. So I believe you mean HACMP 5.4.

You don't need to use multibos. However it is a good idea to have some means to return to the former software levels in case you end up with some AIX-RSCT-HACMP combination that does not work as expected. Using multibos or alt_disk_install makes your life much easier if you don't have a testserver.

Remember that you will have to do a full clustertest after the upgrade.
