iR2774-S3 Question & Answer

Q1The correct operations to replace the damaged disk under RAID 1 mode.

When power on RAIDbox, it will check the disk status at port 0 first. If the disk at port 0 is damaged when power on, the RAIDbox may retry again and again to get the disk status at port 0, then might cause the system boot failed or cannot recognize the RAIDbox. Please pay attention to the following operations if one disk damaged under RAID 1.
1. If one disk is damaged during operation, and the RAIDbox is still power on, please replace the damaged disk by hot-swap to start rebuild. Please DO NOT turn off the power during rebuild. After rebuild finished, you can turn on / off RAIDbox normally.
2. If the disk at port 0 is damaged and the RAIDbox has been powered off (the system has been shut down), please remove the damaged disk and move the disk at port 1 to Port 0 before turning it on again. Hot-swap in a new disk to port 1 to start rebuild after turn RAIDbox on.
3. The port 0 slot for each RAIDbox might be different. Please contact the customer service (supporting@raidontek.com) if need to check.
These operations applies to these RAIDbox models: iR2770, iR2771, iR2774, iR2775, iR2777, iR2970, iR2975, iR2022, iR2023, iR2024, iR2025, iR2300, iR2301, iR2302, iR2320, iR2321, iR2822, iR2823, iR2824
Q2What causes RAIDbox to be unable to recognize my non-brand-new hard drive?

The issue may arise from existing records or data on the hard drive, preventing RAIDbox from recognizing it. To address this, connect the hard drive to your computer individually, clear its sectors using the operating system, and proceed to reformat it. For step-by-step instructions, please consult the operating system's guidelines. Once completed, you can then reintegrate the formatted hard drive into the RAIDbox for utilization.
