NVMe Flash adapter maximum write capability
- Type the following command at the Linux command line and press Enter: nvme smart-log /dev/nvmeX, where nvmeX is the resource name of the NVMe Flash adapter
- If the critical_warning field is 1 (bit 0 is set) and the percentage_used field is 90% or greater, replace the NVMe Flash adapter.
Service tools for Linux on Power servers
- Go to Service and productivity tools and follow the instructions to download service tools.
- Install the NVMe management command line interface (CLI).
- For Red Hat Enterprise Linux (RHEL), type yum install nvme-cli.
- For SUSE Linux Enterprise Server (SLES), type zypper install nvme-cli.
- For more information about using the NVMe CLI, see the README file.
Unsupported Feature: Subsystem-Reset
The PCIe3 3.2 TB NVMe Flash Adapter does not support the Subsystem-Reset feature even though it appears as an available capability. This error is due to a card firmware limitation. Selecting the Subsystem-Reset can lead to command timeouts and must be avoided.
Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new feature and that you determine whether any prerequisites must be met for this feature and attaching devices. To check for the prerequisites, see IBM Prerequisite website.
