EonStor A16E-G2130-4 Installation and Hardware Reference Manual

Audible Alarm - If any errors occur during the initialization process, the onboard alarm will sound in a hastily repeated manner.

Drive tray LEDs should normally start flashing right after power-on, indicating the RAID control unit is attempting to access the hard drives.

NOTE:

The subsystem has been designed to run continuously. Even if a component failure occurs the fault can be corrected online.

4.4 Power Off Procedure

To power down the EonStor subsystem, please follow these steps:

NOTE:

When powering down the EonStor subsystem, please ensure that no time-consuming processes, like a “Logical Drive Parity Regeneration” or a “Media Scan,” are taking place.

Step 1. Stop I/O access to the system.

Stop all I/O accesses to the A16E subsystem. Please refer to the related documentation of your applications.

Step 2. Flush the cache.

Locate the Cache_Dirty LED on the back of controller module to check if there is data cached in the memory. Use the Shutdown Controller function to flush all cached data. This prepares the RAID subsystem to be safely powered down.

Step 3. Turn off the power.

Turn off the power. Once the RAID subsystem has been powered down, other devices connected to the subsystem can be powered down.
