When you add a disk device to your system, you need to add this storage in your Linux environment When you improve the disk capacity of your Virtual Vmware Machine, you just need to configure the device to mount automatically by updating /etc/fstab The process of adding storage to a Red Hat Linux system is relatively straightforward.
Here are the steps that are specific to Red Hat Linux when you don't use LVM:
For Oracle Exadata Database Machine X4-2, Oracle Exadata Database Machine X3-2, and Oracle Exadata Database Machine X2-2, the expected output is one virtual drive, none degraded or offline, five physical devices (one controller four disks), four disks, and no critical or failed disks.There are seven drives in each Oracle Exadata Database Machine X4-8 Full Rack database server.They are configured as one 6-disk RAID-5 with one global hot spare drive by default.Oracle recommends verifying the status of the database server RAID devices to avoid possible performance impact, or an outage.
The impact of validating the RAID devices is minimal.Critical disks should be replaced immediately to avoid the risk of data loss if the number of failed disks in the node exceed the count needed to sustain the operations of the system. If a drive in a database server RAID set is replaced, then the progress of the RAID set rebuild should be monitored.
