Time And Items Required - IBM SAN768B-2 User Manual

Attention: If the new CP blade does not have the same firmware as the active CP
blade, the new blade must be upgraded to the same firmware version. You can
determine the firmware version on the replacement blade and do a firmware
upgrade if necessary after inserting the blade in the chassis, but you MUST disable
high availability (HA) before inserting the new blade. If the new CP blade is
severely down-level, a very specific and detailed procedure must be followed to
bring the blade up to the correct firmware version. Refer to the Fabric OS
Administrator's Guide for information. Also see "Downloading firmware from an
FTP server" on page 94, "Downloading firmware from a USB device" on page 96,
and "Fabric OS firmware updates" on page 50.

Time and items required

The installation procedure for the CP blade takes approximately 30 minutes. The
following items are required for the CP blade installation:
v ESD (electrostatic discharge) grounding strap
v Workstation computer
v Serial cable
v IP address of an FTP server for backing up the SAN768B-2 configuration
v #2 Phillips screwdriver
v Replacement control processor (CP8) blade.
Attention: If you are upgrading through multiple versions of the Fabric OS, refer
to Table 14 on page 94, to see which intermediate versions of the Fabric OS you
will need. Plan carefully and provide for extra time if this is your situation.
Verifying the need for replacement
Confirm that you need to install the CP blade. The following events might indicate
that a CP blade is faulty:
v The status LED on the CP blade displays steady amber, or the power LED is not
lit.
v The CP blade does not respond to Telnet commands, or the serial console is not
available.
v The slotShow command does not show that the CP blade is enabled.
v The haShow command indicates an error.
v The clock is inaccurate, or the CP blade does not boot up or shut down
normally.
v Any of the following messages display in the error log:
– "Slot unknown" message relating to a CP slot
– CP blade errors or I
– FRU: FRU_FAULTY messages for a CP blade
– Configuration loader messages or "Sys PCI config" messages
– Generic system driver messages ("FABSYS")
– Platform system driver messages ("Platform")
– EM messages that indicate a problem with a CP blade
– Function fail messages for the CP master
For more information about error messages, refer to the Fabric OS Message
Reference.
