Network Card Replacement Procedure - Fujitsu PRIMEQUEST 2000 Series Administration Manual

CHAPTER 4 PCI Card Hot Maintenance in Red Hat Enterprise Linux 6
4.6 Hot Replacement of PCI Express Cards
- Check the FC cable connection status.
- Confirm the Storage FC settings.
Confirm that the settings that conform to the actual connection format (Fabric connection or Arbitrated
Loop connection) were made.
If the messages in (*1) and (*2) are displayed but the messages in (*3) are not displayed, the storage is
not yet found. Check the following points again. These are not card problems, so you need not power off
the slot for work.
- Review FC-Switch zoning settings.
- Review storage zoning settings.
- Review storage LUN Mapping settings.
Also, confirm that the storage can be correctly viewed from LUN0.
Eliminate the problem. Then, confirm the settings and recognize the system by using the following
procedure.
1. Confirm the host number of the incorporated FC card from the message at (*1).
xx in scsixx (xx is a numerical value) in the message at (*1) is a host number. In the above example, the
host number is 10.
2. Scan the device by executing the following command.
# echo "-" "-" "-" > /sys/class/scsi_host/hostxx/scan
(# is command prompt)
(xx in hostxx is the host number entered in step 1.)
The command for the above example is as follows.
# echo "-" "-" "-" > /sys/class/scsi_host/host10/scan
3. Confirm that a message like (*3) was output to /var/log/messages.
If this message is not displayed, confirm the settings again.
Note
In specific releases of RHEL, a message like (*1) for confirming FC card incorporation may be output in
the following format with card name information omitted.
scsi10 : on PCI bus 0f device 08 irq 59
In this case, check for the relevant message on the FC card incorporation by using the following
procedure.
a. Confirm the host number.
xx in scsixx (xx is a numerical value) in the message is a host number. In the above example, the
host number is 10.
b. Check whether the following file exists by using the host number.
/sys/class/scsi_host/hostxx/modeldesc
(xx in hostxx is the host number entered in step 1.)
If the file does not exist, the judgment is that no such message was output from the FC card.
c. If the file exists, check the file contents by using the following operation.
# cat /sys/class/scsi_host/hostxx/modeldesc
Emulex LPe1250-F8 8Gb PCIe Fibre Channel Adapter
(xx in hostxx is the host number entered in step 1.)
If the output is like the above, the judgment is that the relevant message was output by the
incorporation of the FC card.

4.6.4 Network card replacement procedure

Network card (referred to below as NIC) replacement using hot plugging needs specific processing before
and after PCI Express slot power-on or power-off. Its procedure also includes to the common PCI Express
card replacement procedure.
