If a Device Is Unlisted/UNCLAIMED in ioscan or Not Displayed in SCSI Adapters Window

If ioscan (HP-UX server) does not list a device connected to the hub or shows the status of the device as UNCLAIMED or NO H/W, or if the SCSI Adapters window (HP NetServer) does not display a device connected to the hub, the problem may be with the device, the hub, the host, or the connections between them. Find the combination of symptoms below that best describes the situation, then attempt the solution. When more than one solution is possible, the most likely is listed first. The hub does not appear in ioscan output or the SCSI Adapters window because it does not have a hardware address.

Symptom

The Port LED for the host or the device is off, and ioscan does not list the device.

The Port LED is on, and ioscan does not list the device.

The Port LED is on, and ioscan Class is “UNKNOWN.”

The Port LED is on, and ioscan shows the S/W State as “UNCLAIMED”or “NO H/W.”

The hub Fault LED is on, and ioscan does not list the device.

Cause/Solution

The connection between the device or host and the hub is faulty. See If a Port LED Is Off on page 76.

The host’s FC adapter is faulty. Replace the adapter.

The FC device is faulty. Replace the device.

There is a duplicate hardware address on the FC-AL loop. Verify that all devices on the loop have unique IDs, then reset the hub.

The software driver is missing on the host. Replace the device driver file.

The device has a duplicate address with another device on the loop. Change the address of one of the devices to a unique address. (The device may need to be powered off and on to reset the address.)

The software driver for the device is incorrect on the host. Replace the device driver file on the system.

The device is faulty. Troubleshoot the device using the instructions that came with the device. Be sure to check the fiber optic transmit or receiving port on the device.

The hub is faulty. Replace the hub.
