270 Troubleshooting
Physical Disks Display Under Connector Not Enclosure Tree Object
Storage Management polls the status of physical disks at frequent intervals.
When the physical disk is located in an enclosure, Storage Management uses
the data reported by the SCSI Enclosure Processor (SEP) to ascertain the
status of the physical disk. In the event that the SEP is not functioning,
Storage Management is still able to poll the status of the physical disk, but
Storage Management is not able to identify the physical disk as being located
in the enclosure. In this case, Storage Management displays the physical disk
directly below the Connector object in the tree view and not under the
enclosure object.
You can resolve this problem by restarting the Server Administrator service or
by rebooting the system. For more information on restarting the Server
Administrator service, see the Server Administrator User’s Guide.
PCIe SSD Troubleshooting
Peripheral Component Interconnect Express (PCIe) Solid-State Drive
(SSD) is not seen in the operating system
Probable Cause:
Hardware is not installed correctly
Solution:
Check the following components to ensure they are plugged:
• Devices: Ensure that the PCIe SSDs are installed in a PCIe SSD
backplane.
• Backplane: Ensure that the cables for the PCIe SSD backplane are
connected.
• Cables: PCIe cables are unique for the configuration. Ensure that the
backplane cable connectors mate with the backplane and the extender
card cable connectors mate with the extender card.
• Extender card: Ensure that the PCIe extender card is plugged into the
correct supported slot.
