PRIMECLUSTER Global Link Services Configuration and Administration Guide: Multipath Function (for Solaris(TM) Operating Environment)

8.2.2.2 Connection Procedure

In order to replace a PCI card by failure etc., the procedure for incorporating the disconnected communication path to the Multipath Function is shown in "Figure 8.3 Connection Procedure."

[Figure 8.3 Connection Procedure]

1. Attach the PCI card
   

   Attach the PCI card, which is replaced, by using the cfgadm command.

   

   • Please attach a PCI card in the same PCI slot as the slot before replacing. Since the device name differs before when it inserts in a different PCI slot, it fails connection.
   • When using ATM cards, it is necessary to connect the stream link between drivers by using "atmlink" command after executing the "cfgadm" command. Please refer to "FUJITSU PCI ATM 1.2 User's Guide" for details.


2. Incorporate to the Multipath Function
   

   In order to incorporate the communication path, which is disconnected by using the PCI Hot Plug function, to the Multipath Function, the connect subcommand of the iompadm command is used. If it succeeds in incorporating, the communication path will be in "stop" state. Please refer to "6.3.2.12 connect subcommand" about the connect subcommand.

   

   

   • When using ATM card, all communication paths correspond to the target NIC are incorporated.


3. Change to online state
   

   The target communication path, which changed to "stop" state, is changed to "active" state or "standby" state by using the start subcommand of the iompadm command. Please refer to "6.3.2.6 start subcommand" about the start subcommand.

   

   

   • When using ATM card, all communication paths correspond to the target NIC are started.
