Replacing the SSDs of a Raid 1 array with larger SSDs

[CJDoor]

I have a DL380 Gen 10 with HPE Smart Array P408i-a SR Gen10 Controller. I should replace the current 2 SSDs of a Raid 1 array with larger 1.9T SSDs.
What is the most correct procedure for carrying out the replacement, without losing data and possibly without having a machine downtime. Is it possible to do this using the controller features?
Thank you and good day

Hi,

I have done this multiple times that way:

Remove Drive 1 (Online), and replace it with the bigger Drive

Wait for rebuild

Remove Drive 2, and replace it with the bigger Drive

Wait for rebuild

Extend the Array and than the Volume or create a new Volume

Backup is all times a good Idea.

Thank You Cali for your answer. To monitor the reconstruction status can I rely on the status LEDs on the disk? Can I extend the volume from smart storage?
A thousand thanks

Better to check it with the Admin Tool (HPE Smart Storage Administrator), which is available as GUI or CLI.

Depending on your OS, maybe already be installed, if you have HPE SPP installed.
Here you can also extend the Aarry after replacement.
