HP Surestore SAN Manager LM Software instruction

No SAN Devices are Available on a Solaris Node

If no SAN devices are listed on a Solaris node, find the cause below that best describes the situation, then attempt the solution.

Symptom Cause/Solution

Assigned SAN devices are not available on a Solaris node.

The host bus adapter (HBA) or drivers are not installed. Install the HBA or

drivers.

SAN-attached storage or other network hardware is powered off. Power

on the drives or network hardware.

Network cables are not connected properly. Verify all cable connections.

There is a failure within the Fibre Channel loop. Power down the Fibre Channel hardware, then power up the hardware to reset the Fibre Channel loop.

Note	Power up the storage devices first, then the hubs/switches
	followed by the SAN Manager LM Windows NT administration
	node, and then all other nodes.

The Solaris node cannot access the SAN database because its Fibre Channel cable is not connected to the loop where the SAN database is located. This problem is most likely to occur in a dual loop configuration in which the SAN database is accessible on one loop but not the other. Make sure the Solaris node is attached to the correct loop.

The Fibre Channel card has become unseated in the computer. Shut

down the computer, remove and reseat the card.

The Fibre Channel card, hub, switch, or storage controller is bad. Run

device and vendor specific diagnostics and replace any bad components.
