Use the following procedure to remove a spinning disk:

1. Power down the appliance before replacing the hard disk drive.
2. Press the release button to unlatch the disk.
3. Use the catch-release lever to pull the disk about two cm (one inch) to disengage contact, as indicated in Figure 15.

4. Remove the disk, extract it from its carrier and handle it with care. Do not drop the disk or ship it loosely in a carton.

5. Securely mount the replacement disk in the drive carrier and replace the carrier in the system.

Notes on Disk Replacement

IP settings and basic network configurations, such as the gateway address, netmask, Grid secret and Grid name, are saved and restored when you replace a failed disk drive. The replaceable hard disk contains only user data. Should the hard disk drive in an appliance stop working for any reason, and the appliance is part of an HA pair, it will come offline and its HA partner system will come online. If the hard disk has an issue and is replaced, the NIOS within the downed system detects the new hard disk and initializes it for NIOS usage.
If the appliance is running in an Infoblox Grid, the system then communicates with the current Grid Master, downloads any remaining configuration, and then automatically rejoins the Grid. In most cases, recovery within an HA pair and in the Grid takes only a few minutes after the hard disk is replaced.
If the appliance runs in stand-alone mode without failover, a backup of the user data must be restored or the system configured from scratch. Infoblox recommends regular backups of standalone appliance data. Consult the topic Backing Up and Restoring Configuration Files in the NIOS Administrator's Guide for your system.
