Netgear RN12P1220 – ReadyNAS 3200 24TB Network Storage System Hardware Manual

Boot Menu

Use the boot menu to restart or troubleshoot your ReadyNAS unit. It has the following boot 
modes:

Normal. Initiates a normal boot process, just like booting using the Power button. 

Factory default. Initiates a short disk test that takes approximately 5 minutes, then 

begins a 10-minute time-out period waiting for RAIDar. During the 10-minute time-out 
period, the system can be powered off safely without causing any data loss. After 10 
minutes, or if you select the factory default option using RAIDar during the time-out 
period, the factory process begins. 

OS reinstall. Reinstalls the firmware from the internal flash to the disks. Use the OS 

reinstall boot mode when the system crashes and corrupts some configuration files. OS 
reinstall boot mode also resets some settings on your unit, such as Internet protocol 
settings and the administrator password, to defaults. 

Tech support. Boots into a low-level diagnostic mode. Use the tech support boot mode 

only when instructed to do so by a NETGEAR technical support representative.

Skip volume check. After a system crash, the system tries to scan and fix the volume 

via a file system check. If several problems are found on a disk, this process can stall, 
causing the system not to boot. Use this option to skip the scan and let the system boot. 

Memory test. Performs a memory test. The pass or fail result is reported using the unit’s 

LEDs. Contact a NETGEAR technical support representative to interpret memory test 
results.

Disk test. Performs an offline full disk test. This can take 4 hours or more, depending on 

the size of your disks. Any problems are reported in the RAIDar discovery tool.
