Solution

There have recently been cases where the Brisque 5.x Upd (image) was either corrupted or incomplete when it was downloaded from the FTP. This procedure suggests two methods for checking the Upd validity prior to its installation.

Validate the Upd checksum:

Use the AIX sum command to validate the checksum, and compare it to the checksum value supplied by CIL.
Note: In the future, this value will be supplied with each Upd.

The sum command provides two numbers: the first number is the checksum and the second number is the number of 1024-byte blocks. For example, type:
sum Upd_Brisque5132_Output.image (where Upd_Brisque5132_Output.image is the original Upd). The system displays:
47865 280778 Upd_Brisque5132_Output.image

Then type: sum Upd_Brisque5132_Output.image.new (where Upd_Brisque5132_Output.image.new is the Upd after download). The system displays:
02024 280778 Upd_Brisque5132_Output.image.new

In this example the images differ in their checksum, although the byte count is identical. This can occur if the image was downloaded in text mode, and not in binary FTP mode.

Validate the Upd contents:

Browse your image to verify that there are no errors when you use the restore command. For example, type:
restore -Tvf Upd_Brisque5132_Output.image

The system displays:
Please mount volume 1 on Upd_Brisque5132_Output.image
... and press Enter to continue

After performing the previous instruction, the system displays:
New volume on Upd_Brisque5132_Output.image:
Cluster 51200 bytes (100 blocks).
Volume number 1

In this example no errors are displayed, which indicates that the Upd download was successful.
