Last updated on MARCH 03, 2023

Applies to:

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

Goal

The goal of this document is to define the steps required for the Exadata Disk Swap Service.
This document will describe the steps necessary when Exadata Database Machine customers opt for the Exadata Disk Swap Service to be performed. The service allows customers to change the disks in the Exadata storage servers in their X6 and later generation Exadata and Storage Expansion Racks. They can change High Capacity disks, either 8T, 10T or 14T to 18T High Capacity disks. Swapping from High Capacity disks to High Performance disks is not part of the service. This note will concentrate on Disk Swap for X6, X7, X8 and X8M generation Exadata Database Machines. Please see the table below for the various swapping options.

NOTE: Instructions for M2 based systems such as the X7, X8 and X8M will be provided shortly.

Disk swaps are not supported on V1, V2, X2, X3, X4 and X5 systems.
Disk swaps are not supported on 1/8th rack systems.
Disk swaps to any size other than 18T High Capacity disks are not offered
18T High Capacity disks are available for order.
18T disks can be swapped into X6, X7 and X8/X8M generation Exadata and Storage Expansion Racks, however the cells must be imaged with Exadata Storage Server software version 21.1.0.0.0 or later prior to swapping the disks. Please see document 888828.1 Version and Compatibility for additional Grid Infrastructure software version requirements.

The following table shows the various options by Exadata hardware type.

Swap Options by Exadata Hardware Release
Exadata Hardware	Original Disk Type	Original Disk Size	New Disk Type	New Disk Size	Disk Cage Required
X6	High Capacity	8T	High Capacity	18T	N
X6	High Capacity	14T	High Capacity	18T	N
X7	High Capacity	10T	High Capacity	18T	N
X7	High Capacity	14T	High Capacity	18T	N
X8	High Capacity	14T	High Capacity	18T	N
X8M	High Capacity	14T	High Capacity	18T	N

Depending on the choice of disks, free space and size of the rack, the service can either be performed in an online rolling fashion or must be done offline. This document will provide the steps for performing both methods providing scripts, automation and sanity checks where possible.
