Installing HyperFabric
Installing HyperFabric Adapters
• 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 SAM 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, SAM 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 |
| 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 “Managing |
| PCI Cards with OLAR” chapter of the Configuring |
| 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 SAM 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, SAM checks the replacement adapter to |
| |
| make sure it is permitted according to the |
| SAM automatically activates it. If it is not permitted, SAM displays an error message. |
