If a Huawei-developed driver is installed, the setting takes effect immediately without needing
to stop I/O services. If an open-source or system-provided driver is installed, the setting takes
effect after the server is restarted.
Example
# Detach namespace 1 of the
nvme0
SSD to NVMe controller 1.
[root@localhost tool]#
hioadm namespace -d nvme0 -t 3 -i 1 -c 1
detaching the namespace successed.
Please remove and then install the NVMe driver or reboot the OS.
System Response
If
detach failed
is displayed, the operation failed. The failure causes are as follows:
l
The namespace is not attached to the NVMe controller.
l
The NVMe controller ID is invalid.
