ftp> open server
ftp> user admin
ftp> Password: adminpw
ftp> cd /tftpboot
ftp> bin
ftp> get zImage.134 zImage
ftp> quit
NOTE:
The destination file name in the /mnt/flash directory must be zImage. Example
(hostname = server; directory = /tftpboot; username= admin; password = adminpw;
firmware filename on that server = zImage.134).
NOTE: Due to space limitations, the new zImage file may not be downloaded with a different
name, then renamed. The ACS searches for a file named zImage when booting and there is
no room in flash for two zImage files.
Step 4 - Verify zImage.
To make sure the downloaded file is not corrupted and to verify the zImage saved
in flash run the following command:
md5sum /mnt/flash/zImage
The system responds with a message similar to the following:
5bcc7d9b3c61502b5c9269cbecd20317 /mnt/flash/zImage
Step 5 - Check the system’s response against the “.md5” zImage text file on the
tftp server.
For example, the zImage zvmppccs.1005_qa.acs-k26.md5 text file contains the
following information:
5bcc7d9b3c61502b5c9269cbecd20317 /tftpboot/zvmppccs.1005_qa.acs-k26
If the alphanuemeric string matches the downloaded file is not corrupted.
Step 6 - Issue the command reboot.
# reboot
Step 7 - Confirm that the new Linux kernel has taken over.
After rebooting, the new Linux kernel will take over. This can be confirmed by
typing the following to see the Linux kernel version:
# cat /proc/version
