Updating and managing the system flash using Linux service aids
This section describes how to update and verify the system flash using Linux
service aids.
Updating the system flash using Linux
The Linux service aid for managing the system flash is separate from the operating
system installation and is available for download from the following Web site:
http://techsupport.services.ibm.com/server/lopdiags/.
Note: The update_flash command can only be performed if the update_flash
service aid has been installed on the blade server for the appropriate version
of Linux.
Complete the following steps to update the system firmware code:
1. Obtain the flash image that you want to update and place it in the
/etc/microcode directory (create the directory, if it does not exist).
2. Issue the following command:
update_flash -f /etc/microcode/<update_image_name>
After the system reboots successfully and once you are satisfied with the
functionality of the new image, commit the update using the following Linux
command:
update_flash -c
This will copy your new image from the TEMP side to PERM side of flash.
Verifying the system firmware levels using Linux
To verify the system firmware levels on the PERM and TEMP sides, enter the
following command at the Linux prompt (the entire command must be entered on
one line):
for file in `ls /proc/device-tree/openprom/*bank*`; do echo $file;
cat $file; echo; echo; done
For Example: This command will return output similar to the following information:
/proc/device-tree/openprom/ibm,fw-bank
P
/proc/device-tree/openprom/ibm,fw-perm-bank
FW04310120, 17:16:09, 07/26/2004
/proc/device-tree/openprom/ibm,fw-temp-bank
FW04310120, 17:16:09, 07/26/2004
v
The value for ibm,fw-bank indicates what side you booted from
(T for TEMP, P for PERM).
v
The value for ibm,fw-perm-bank identifies the firmware version,
date, and time stamp of the firmware on the PERM side.
v The value for ibm,fw-temp-bank indicates the firmware version,
date, and time stamp of the firmware on the TEMP side.
Notes:
v
If you have to recover the system firmware code, see “Recovering the system
firmware code” on page 95.
v The IBM Remote Deployment Manager (RDM) program does not support the
BladeCenter JS20 Type 8842.
