En los servidores SPARC S7-2L con una configuración de placa posterior de 12 unidades y solo unidades NVMe, prtdiag muestra nombres NAC incorrectos para las unidades NVMe de las ranuras 3, 4 y 5, como se muestra a continuación.
======================================== IO Devices =======================================
Slot + Bus Name + Model Max Speed Cur Speed
Status Type Path /Width /Width
-------------------------------------------------------------------------------------------
...
...
/SYS/MB/PCIE_SWITCH1 PCIE nvme-pciexclass,010802 8.0GT/x4 8.0GT/x4
/pci@300/pci@2/pci@0/pci@6/nvme@0
/SYS/MB/PCIE_SWITCH1 PCIE nvme-pciexclass,010802 8.0GT/x4 8.0GT/x4
/pci@300/pci@2/pci@0/pci@7/nvme@0
...
/SYS/MB/CMP1/IOS0 PCIX nvme-pciexclass,010802 8.0GT/x4 8.0GT/x4
/pci@302/pci@2/pci@0/pci@4/nvme@0
...
...
Con los nombres NAC correctos para las unidades NMVe de las ranuras 3, 4 y 5, la salida de prtdiag debería ser la siguiente:
======================================== IO Devices =======================================
Slot + Bus Name + Model Max Speed Cur Speed
Status Type Path /Width /Width
-------------------------------------------------------------------------------------------
...
...
/SYS/DBP/NVME4 PCIE nvme-pciexclass,010802 8.0GT/x4 8.0GT/x4
/pci@300/pci@2/pci@0/pci@6/nvme@0
/SYS/DBP/NVME3 PCIE nvme-pciexclass,010802 8.0GT/x4 8.0GT/x4
/pci@300/pci@2/pci@0/pci@7/nvme@0
/SYS/MB/PCIE5 PCIE nvme-pciexclass,010802 8.0GT/x4 8.0GT/x4
/pci@300/pci@2/pci@0/pci@15/nvme@0
...
...
Solución alternativa: use el comando format o el comando diskinfo para encontrar los nombres NAC correctos y las rutas de dispositivo asociadas para las unidades NVMe con esta configuración. Por ejemplo, escriba:
# diskinfo
