Reclaiming the hotspare after upgrading to 12.1.2.1.0 or later (Doc ID 1956550.1)

Last updated on FEBRUARY 15, 2016

Applies to:

Oracle Exadata Storage Server Software - Version 11.2.2.4.2 and later
Linux x86-64

Goal

This document describes how to manually add the hotspare to the RAID 5 when reclaimdisk.sh cannot do it (starting 12.1.2.1.0). For Exadata releases earlier than 12.1.2.1.0 <Document 1582139.1> needs to be followed.

Systems freshly imaged to Exadata release 12.1.2.1.0 will not have a hotspare. For those cases reclaimdisk will be used to reclaim diskspace from the volume group when choosing either Oracle VM or Oracle Linux 6 on the database server - reclaim will happen within the same RAID5 configuration of 4 (or 8) disks. For systems upgraded to 12.1.2.1.0 that previously had a hotspare, reclaimdisk.sh cannot be used to reclaim diskspace from the hotspare. As shown in the example below reclaimdisk will not work to reclaim the hotspare in release 12.1.2.1.0.

In this process the database server will be rebooted twice. It is assumed the Grid Infrastructre is disabled to start after node boot-up.
