ES80 replace ES45

ES80 replace ES45

Our original environment is as below,

---------------

1. ES45 X 2

2. HP Tru64 5.1A

3. Oracle 9.0.1.4RAC (2 instances on each node)

---------------

Because of enhancing H/W, we would like to replace one node from ES45 to ES80. In other word, it will become ES80 + ES45 (TruCluster).

Due to ES80, we should upgrade 5.1A to 5.1B.

But this is production database, how can we do for min downtime?



Thanks

ES80 replace ES45

Hi Eric,



First please install the V5.1B/PK4 in local disk on ES80 then create a new cluster

environment and RAC into these spare share disks with old cluster on same EVA or HSG80.



It should be joined both ES80 and one ES45 (that gets from clu_delete_member at the old

cluster env.) into new cluster env. Waiting a down time schedule to exchange all of RAC

DB files' access from old cluster with only one ES45 (V5.1A) to new cluster with two members on ES80 and ES45 (V5.1B).



PS: This is a critical system migration plan that needs to consult with HP for further discussion.



Best regards,

Richard.
