Thanks for posting in the Intel® SSD community.
What is the make and model of the PCIe extenders?
Have you tried to connect one of the SSDs directly to the board without the PCIe extender?
If you connect one SSD directly and the ISDCT shows the SSD, it would mean the issue is related to the PCIe extender. As the extenders are hardware not built by Intel some of them may have a conflict with the ISDCT.
I will be waiting for your feedback.
Hi Juan N,
Thank you for your response. For this server with no RAID cards, we need to have the PCIe extenders as a must. I am not sure if this is an Intel PCIe extender. I might need to use nvme-cli to format.
Another question I had was can I use this tool on Samsung disks as well?
ISDCT is designed to work with Intel SSDs, a Samsung disk won't be recognized.
The PCIe extender could be causing the issue. If you can get the make and model this will help us to find the root cause of the issue.
Using the NVME-CLI would be a good option for you to format the SSDs through the PCIe extender card.
