Time And Items Required; Verifying The Need For Replacement - IBM System Storage SAN384B-2 Installation, Service And 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 78, "Downloading firmware from a USB device" on page 80,
and "Fabric OS firmware updates" on page 48.

Time and items required

The installation procedure for the CP blade takes approximately 30 minutes. The
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 SAN384B-2 configuration
v #2 Phillips screwdriver
v Replacement CP blade. The SAN384B-2 requires the CP8 blade.
Attention: If you are upgrading through multiple versions of the Fabric OS, refer
to Table 14 on page 78, to see if you will need any intermediate versions of the
Fabric OS. Plan carefully and provide for extra time if this is your situation.

Verifying the need for replacement

Confirm that you need to replace the CP blade. The 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
v The CP blade does not respond to Telnet commands, or the serial console is not
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
