This article summarizes the steps to perform a correct disk replacement on SynetoOS 6.

IMPORTANT

It is essential that every Syneto appliance owner understands the information contained herein, with the aim of operating autonomously and safely on their systems and speeding up replacement operations.

Prerequisites

Ensure the following prerequisites are met before starting:

Replacement via GUI

Step 1. Login to SynetoOS GUI

https://<your_ip_address_or_hostname>

Step 2. From System menu, click on Drives

Step 3. Select the faulted disk

On the right side, the disk information will be displayed

Step 4. In the top-right corner, click on the three dots and then on Blink LED

Locate the disk in the correct position on the server by identifying the bay with the blinking light.

Step 5. In the top-right corner, click on the three dots and then on Stop LED

Step 6. Replace the disk

Replace the disk with the new one, making sure to insert it into the slot that is blinking.

To remove the disk, it is necessary to detach the trays from the old disk and mount them onto the new one.

The old disk will appear like this in the web interface:

Step 7. Find new disk in the web interface

Click the Refresh button until the new disk appears

Step 8. Select the old disk (Step 5), then click on Replace

Step 9. Select the new disk and click on Replace

Wait for the operation to complete

Replacement via CLI

Step 1. Connect to SynetoOS appliance via SSH as admin

ssh admin@<your_ip_address_or_hostname>

Step 2. Get root privileges

sudo su -

Step 3. List all pools and statuses

zpool status

Step 4. Retrieve all disks available and information

config disk show

Step 5. Replace the disk with a new one (replace <pool_name>, <old_disk> and <new_disk> with the correct information)

zpool attach <pool_name> <old_disk> <new_disk>

EXAMPLE

zpool attach hybrid c0t5000C50099FF4507d0 c0t5000C500C2536A77d0

• hybrid (<pool_name>)
• c0t5000C50099FF4507d0 (<old_disk>)
• c0t5000C500C2536A77d0 (<new_disk>)

In case of output error, you can try running the same command adding the “-f” parameter:

• -f: forces the use of the <new_disk> even if in use

zpool attach -f hybrid c0t5000C50099FF4507d0 c0t5000C500C2536A77d0

Resilvering Status

Check resilvering status ("How to monitor resilvering status in SynetoOS 6").

Return of replaced disc (optional)

Return is necessary

In the event that it is necessary to return the replaced disk (i.e. in the case of a disk still under warranty or hardware intervention carried out without an on-site Syneto technician), it will be necessary to proceed with the shipment of the disk.

The process will be completely managed by the Syneto Delivery team, through the support ticket, which will agree directly with the customer to schedule the collection of the disk through a courier. After the collection of the replaced disk by the courier, the support ticket will be closed.

Return is not necessary

In case there is no disk to return, the support ticket may be closed right after Syneto Customer Support has verified that the new disk has been shipped and the replacement instructions (this article) have been correctly shared. In case of further issues, the customer will be able to reopen the same ticket to request new assistance.
