2.3 Maintaining Flash Disks on Exadata Database Servers

Flash disks should be monitored and replaced when necessary.

Starting with Exadata Database Machine X7-8, the database servers contain flash devices instead of hard disks. These flash devices can be replaced without shutting down the server.

• Monitoring the Status of Flash Disks
  You can monitor the status of a flash disk on the Exadata Database Machine by checking its attributes with the DBMCLI LIST PHYSICALDISK command.
• Performing a Hot-Pluggable Replacement of a Flash Disk
  For Oracle Exadata X7-8 and X8-8 models, the database server uses hot-pluggable flash disks instead of hard disk drives.
