17. Run
reclaimdisks.sh
on each database server.
The
/opt/oracle.SupportTools/reclaimdisks.sh -free -reclaim
command reclaims
disk space reserved for the deployment type not selected. The command takes
less than 5 minutes, approximately. Systems are imaged with disks configured
with RAID5; a RAID rebuild is no longer part of the
reclaimdisks.sh
process.
Do not skip this step. Skipping this step results in unused space that can no longer
be reclaimed by
reclaimdisks.sh
.
For example:
# /opt/oracle.SupportTools/reclaimdisks.sh -free -reclaim
