HP HyperFabric manual Card OL* Support Guide

Installing HyperFabric

Installing HyperFabric Adapters

• If the necessary driver is not present and the driver is a dynamically loadable kernel module (DLKM), it can be loaded manually. See the “Dynamically Loadable Kernel Modules” section in “Interface Card OL* Support Guide” for more information.

• If the driver is static and not configured in the kernel, then the card cannot be added online. The card could be physically inserted online, but no driver would claim it.

	If there is any question about the driver’s presence, or if it is uncertain that the
	replacement card is identical to the existing card, ioscan can be used together with rad
	to investigate.
	If more than one operational HyperFabric adapter is present when SMH requests the
	suspend operation for all ports on the target adapter, HyperFabric will redirect the
	target adapter’s traffic to a local backup adapter using local failover. Client applications
	using the replaced adapter will not be interrupted in any way.
	If the adapter being replacing is active and it is the only operational HyperFabric
	adapter on the HP 9000 system, SMH displays the following warning message:
	WARNING: You have 1 operational HyperFabric card. If you go ahead with this
	operation you will lose network access via HyperFabric until the on-line
	replaced HyperFabric card becomes operational.
	You are asked if you want to continue. If you reply Yes, client applications are
	suspended. Replace the adapter according to the procedure described in the Interface
	Card OL* Support Guide.
	When an adapter has been replaced, client application activity resumes unless the TCP
	timers or the application timers have popped.
CAUTION	Do not use the clic_start command or the clic_shutdown command, while an
	installed adapter is suspended. Do not use SMH to start or stop HyperFabric while an
	installed adapter is suspended. The operation will fail and an error message will be
	displayed.
	After a HyperFabric adapter has been replaced, SMH checks the replacement adapter to
	make sure it is permitted according to the like-for-like rules. If the adapter is permitted,
	SMH automatically activates it. If it is not permitted, SMH displays an error message.
