Use the boot menu to restart or troubleshoot your ReadyNAS storage system. Your storage system has the following boot modes:
- Normal. Initiates a normal boot process, just like booting using the Power button.
- Factory default. Initiates a 10-minute time-out period before resetting.
-
WARNING: The factory default reboot process resets the unit to factory settings, erases all data, resets all defaults, and reformats the disk to X-RAID2.
- 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 storage system, 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.
-
WARNING: Use the skip volume check boot mode only when instructed to do so by a NETGEAR technical support representative, otherwise data loss might occur.
- Memory test. Performs a memory test. The pass or fail result is reported using the storage system'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.
To access the boot menu:
- Power off your unit.
- Using a straightened paper clip, press and hold the SYS button.
- Press the Power button to power on the unit.
- Continue to press the SYS button until the LEDs are all lit.
