2.1.2 Replacement of redundant configuration

When the PCI cards are needed to be replaced in redundant configuration with using redundant software that controls the multipath, the PCI cards can be replaced without stopping the high-level products (services).

The flow of the replacement procedure of PCI cards for redundant configuration is as follows.
Please refer to "Chapter 3 File Devices" and "Chapter 4 Network Devices" for detailed replacement procedure.

File devices procedures

1. Stop the daemons

   If you use the Fibre Channel Card (PW028FC3*/PW028FC4*/PW028FC5*), stop the daemons.

2. Locating the PCI cards and the system boards

   Locate the system boards equipped with the faulty PCI cards and the connected devices and interfaces.

3. Disconnect from redundant system

   Disconnect the devices path and interfaces of PCI cards from the redundant system.

4. Detaching the system boards

   Detach the system boards equipped with the faulty PCI cards and enable the replacement of the PCI cards, then check the multipath status.

5. Replacing the PCI cards

   Pull out the system boards equipped with the faulty PCI cards and replace the PCI cards, then mount back the system boards.

6. Attaching the system boards

   Attach the system boards equipped with the replaced PCI cards and enable the use of the PCI cards, then check the multipath status.

7. Connect to redundant system

   Connect device paths and interfaces of the replaced PCI card to the redundant system.

   If necessary, switch back the active paths.

8. Start the daemons

   If you use the Fibre Channel Card (PW028FC3*/PW028FC4*/PW028FC5*), start the daemons.

Network devices procedures

1. Locating the PCI cards and the system boards

   Locate the system boards equipped with the faulty PCI cards and the connected devices and interfaces.

2. Detaching the system boards

   Detach the system boards equipped with the faulty PCI cards and enable the replacement of the PCI cards, then check the multipath status.

3. Replacing the PCI cards

   Pull out the system boards equipped with the faulty PCI cards and replace the PCI cards, then mount back the system boards.

4. Attaching the system boards

   Attach the system boards equipped with the replaced PCI cards and enable the use of the PCI cards, then check the multipath status.If necessary, switch back the active paths.
