Software Upgrade Instructions
6.2 Performing the Software Upgrade
To perform the software upgrade, you will use the operation upgrade com-
mand in AMI. The underlying file transfer mechanism used by this command
is TFTP. If TFTP is to run properly between two machines, the file(s) being
transferred must reside in a specific directory called “tftpboot.” TFTP oper-
ates this way for security reasons.
When the operation upgrade command is issued in AMI, the switch starts
up TFTP to the host, which searches for the file requested. The host, which is
running TFTP, looks for the file in /tftpboot. When creating the path and file-
name to transfer the file to the switch, the host appends “/tftpboot” in front
of the path name that appears after the colon (:) in the operation upgrade
command.
For example, issuing operation upgrade 169.144.3.54:asx-scp_4.0.0_1.3
will cause TFTP to transfer the file “/tftpboot/asx-scp_4.0.0_1.3.” For this rea-
son, it is imperative that you place the upgrade file in the /tftpboot directory
on the workstation to which you downloaded/extracted the file. If this direc-
tory does not already exist, create it by issuing the following command on the
workstation:
mkdir /tftpboot
Now move the upgrade file to the /tftpboot directory with the following
command:
mv <filename> /tftpboot
Once you have moved the software upgrade file to the /tftpboot directory on
your workstation, you need to invoke the upgrade process on the SCP. Log in
to AMI and enter the following parameters at the
localhost::> prompt:
operation upgrade ?
This will display the specific parameters that you need to enter as follows:
upgrade <remotehost>:<full path to remotefile>
Enter the remote machine name or IP address of the workstation to which
you downloaded/extracted the upgrade file in the remotehost field. In the
full path to remotefile field, enter ONLY the filename of the upgrade file
(which should be in the /tftpboot directory on the remote host).
