3. Tighten the thumb screw inside each handle using the Phillips screwdriver.
4.
Turn the CP blade on by sliding the ON/OFF switch in the top handle up, to
cover the thumb screw.
5. Verify that the power LED is green. If not, ensure that the CP blade has power
and is firmly seated and that the ejectors are in the locked position.
6. Connect the cables to the new CP blade.
7. Remain logged in to the active CP and continue to “Verifying operation of the
new CP blade.”
Verifying operation of the new CP blade
To verify that boot and POST are complete on the new CP blade and that the CP
blade has achieved failover redundancy, complete the following steps.
1. Enter
slotShow
. The command output shows the new CP blade as “enabled.” If
the standby CP is unresponsive, try unplugging the new CP blade, running
haDisable
on the active CP blade, and plugging the new CP blade back in. At
that point, you can repeat step 1 to begin the verification process again.
2. Determine the Fabric OS version by entering
firmwareShow
. If the serial console
on the replacement CP blade is connected, issue the
firmwareShow
command
there. More information is available through the console.
Attention: The SAN768B-2 requires Fabric OS 7.0.0 or later to be recognized.
The FC8-32E and FC8-48E blades require FOS 7.0.1 or later. If the firmware on
the replacement blade is earlier than 7.0.0, it must be brought up to the version
(7.0.0 or later) on the active CP blade, which must be at least 7.0.0. IBM
recommends upgrading to the latest version available.
3. If the firmware versions for both CP blades are the same, skip to “Completing
the CP8 blade replacement” on page 98. If the firmware version on the
replacement blade does not match that on the active CP blade, a warning
message appears with the results of the
firmwareShow
command. The results of
the
firmwareShow
command may look similar to the following example. Note
the warning message at the end of the output.

WARNING: The local CP and remote CP have different versions
of firmware, please retry firmwaredownload command.
4. You must bring the replacement blade to the same firmware level as the active
blade by using the
firmwareDownload -s
command directly on the replacement
blade to bring it up to the proper level. The
firmwareShow
command results
show which slots hold the active and standby (replacement) CP blades. If you
are using an FTP server to download the firmware, skip to “Downloading
firmware from an FTP server” on page 94. If you are using a USB device to
download the firmware, skip to “Downloading firmware from a USB device”
on page 96. If the firmware on the standby CP blade is more than one level
down from the level on the active CP blade, you must have formatted USB
devices for each of the versions you will need to upgrade. Table 14 on page 94
provides the supported upgrade paths for multiple FOS versions.
