Fixed in Oracle Solaris SRU 10 (Hardware Management Pack for Oracle Solaris version 220.127.116.11).
When viewed from Oracle ILOM, the flash storage on NVMe flash accelerator PCIe cards in SPARC systems is not listed as add-on disks under the System/Storage/Disks component hierarchy. This has to do with the way the hardware management agent, which is used to provide storage information to Oracle ILOM, currently classifies storage on NVMe flash accelerator PCIe cards.
To obtain basic information about installed NVMe flash accelerator PCIe cards in Oracle ILOM, look under System/PCI_Devices/Add-on. For example:
show /System/PCI_Devices/Add-on/Device_6 Targets: Properties: part_number = 7110865 description = Oracle Flash Accelerator F160 PCIe Card: 1.6TB, NVMe PCIe 3.0 location = PCIE6 (PCIe Slot 6) pci_vendor_id = 0x8086 pci_device_id = 0x0953 pci_subvendor_id = 0x8086 pci_subdevice_id = 0x370b Commands: cd show
For additional information about, and configuration of, installed NVMe flash accelerator PCIe cards, use the Oracle Hardware Management Pack nvmeadm command.
