Oracle I/O Domain Administration Guide

Delete All Nodes in a Cluster

Use this procedure to delete all the nodes in a cluster before you delete the associated Database I/O Domains.

In this scenario, you will delete all active members of a grid infrastructure resulting in the destruction of the whole cluster.

1. Identify the diskgroups and associated griddisks.

   For example, identify the griddisk prefix in the output (DATAJNGZ and RECOJNGZ).

   oracle@etc5mzdbadm030201:~$ asmcmd lsdsk
   Path
   o/192.0.2.1;192.0.2.2/DATAJNGZ_FD_00_etc5mceladm01

   o/192.0.2.5;192.0.2.6/DATAJNGZ_FD_01_etc5mceladm03
   o/192.0.2.5;192.0.2.6/DATAJNGZ_FD_02_etc5mceladm03
   o/192.0.2.5;192.0.2.6/DATAJNGZ_FD_03_etc5mceladm03
   o/192.0.2.5;192.0.2.6/RECOJNGZ_FD_00_etc5mceladm03
   o/192.0.2.5;192.0.2.6/RECOJNGZ_FD_01_etc5mceladm03
   o/192.0.2.5;192.0.2.6/RECOJNGZ_FD_02_etc5mceladm03
   o/192.0.2.5;192.0.2.6/RECOJNGZ_FD_03_etc5mceladm03
   oracle@etc5mzdbadm030201:~$
   

2. Delete the associated Database Domains, then return to Step 3 in this procedure.

   See Delete a Domain.

3. Delete the griddisks from the storage cells.

   Log in to each cell and drop the griddisks. For example:

   CellCLI> drop griddisk all prefix=RECOJNGZ force
