4.1.2 Replacement of redundant configuration

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

This section shows the replacement procedures of system boards and PCI cards with using the following redundant software products.

• SynfinityLink
• PRIMECLUSTER GLS

In case of using the other redundant software products, refer to the manual for each product.

Notes

The redundant line control function of SynfinityLink 2.2 does not support the hot replacement by using DR function. Please use the redundant line control function of PRIMECLUSTER GLS 4.0 or later.

1. Locating the PCI cards and the system boards

   Using the following procedures, locate the system boards equipped with the faulty PCI cards and the connected interfaces.

   1. Check the interface (example:hme2) of replacement target by the WARNING messages output to console etc.

   2. Locate the system boards equipped with the faulty PCI cards and display a list of interfaces about all PCI cards of the system boards by using the drcstat(1M) command.

      # /opt/FJSVhwr/sbin/drcstat -device | grep hme <Return>
      00-ONBOARD "/pci@83,4000/network@1,1" 0 "hme"
      01-ONBOARD "/pci@87,4000/network@1,1" 1 "hme"
      01-PCI#3B "/pci@87,4000/SUNW,hme@2,1" 2 "hme"
      # /opt/FJSVhwr/sbin/drcstat -device sb01 <Return>
      01-PCI#0B "/pci@84,4000/scsi@2" 2 "glm"
      01-PCI#0B "/pci@84,4000/scsi@2,1" 3 "glm"
      01-PCI#0B "/pci@84,4000/scsi@2/sd@1,0" 1 "sd"
      01-PCI#0B "/pci@84,4000/scsi@2/sd@3,0" 20 "sd"
      01-ONBOARD "/pci@87,4000/ebus@1/FJSV,panel@14,280030" 1 "FJSVpanel"
      01-ONBOARD "/pci@87,4000/ebus@1/FJSV,scfc@14,200000" 1 "FJSVscf2"
      01-ONBOARD "/pci@87,4000/ebus@1/FJSV,se@14,400000" 1 "se"
      01-ONBOARD "/pci@87,4000/network@1,1" 1 "hme"
      01-PCI#3B "/pci@87,4000/SUNW,hme@2,1" 2 "hme"

      The above example shows the relevant interface is hme2("/pci@87,4000/SUNW,hme@2,1" 2 "hme"), and so the faulty PCI card is equipped with the PCI slot#3B of the system board#01.

      And it is understood that the hme1 and SCSI devices excluding hme2 exist on the relevant system board from the results of execution of the second command.
      It is possible to ignore about se driver and scf driver (FJSVscfx).
      Refer to "Enhanced Support Facility User's Guide" for details of se driver and scf driver.

2. Detaching the system boards
   1. Detach the system boards equipped with the faulty PCI cards by using the drc(1M) command.

      # /opt/FJSVhwr/sbin/drc -disconnect sb01 -keep <Return>

      Notes

      When the ATM cards (GP7B8AT1) are mounted on more than one system board, the operation below cannot be performed for the system boards on which the ATM cards are mounted.
      Performing this operation will also disable communication by the ATM card.

      1) Detaching the system board during configuration modification via system reboot

      # drc -connect sb01 -reset <Return><System reboot>

      2) Moving a system board to another partition

      # drc -disconnect sb01 -next 1 -reset <Return><System reboot>

   2. Check if the status of the system boards is changed to "Unconfigured".

      # /opt/FJSVhwr/sbin/drcstat -board sb01
      SB BN Status (Detail) PID Next_PID Board_Type CPU(MHz)
      -- -- --------------- --- -------- ---------- --------
      01 0 Unconfigured 00 00 10 300

3. Replacing the PCI cards

   Pull out the detached system boards and replace the faulty PCI cards located in step 1 to replacement parts, then mount back the system boards. A certified service engineer takes charge of this work.

4. Attaching the system boards
   1. Attach the system boards equipped with the replaced PCI cards by using the drc(1M) command.

      # /opt/FJSVhwr/sbin/drc -connect sb01 <Return>

   2. Check if the status of the system boards is changed to "Configured".

      # /opt/FJSVhwr/sbin/drcstat -board sb01
      SB BN Status (Detail) PID Next_PID Board_Type CPU(MHz)
      -- -- --------------- --- -------- ---------- --------
      01 0 Configured 00 00 10 300

   3. Check the interface status in redundant software.
      Refer to the manual for each redundant software product about how to check the interface status in it.

5. Switching back active paths

   If necessary, switch back the path failed over by hot replacement of DR function to the original path side before the replacement.
   Refer to the manual for each redundant software product about how to switch back active paths.
