Firmware download troubleshooting
The following section states a possible issue and the recommended solution for firmware download
errors.
Problem Resolution
If you configured an internal FTP server and the
Management application server is running
IPv6, firmware download is not supported. Choose from one of the following options:
•
If the Management application is running IPv6 only, configure an external FTP server.
•
If the Management application is running IPv4 and IPv6, configure IPv4 to be the
preferred address.
Firmware download using SCP/SFTP does not
work because of one of the following issues:
•
For internal SCP/SFTP server, the
application was uninstalled and
reinstalled without migration
•
For external SCP/SFTP server, the SSH
handshake keypair is changed
-
manually
-
due to an external server reinstall
-
due to the SCP/SFTP server
preference (Options dialog box)
being changed from built-in to
external (installed on same machine)
or vice versa
Clear the SSH (SCP/SFTP) server IP address or hostname from the known_hosts table of
the device.
•
For Fabric OS devices, use the following command:
sw0:FID128:admin> sshutil delknownhost
IP Address/Hostname to be deleted: SSH_server_IP_address
where
SSH_server_IP_address
is the IP address of the SSH server you want to
delete.
•
For Network OS devices running firmware version 3.0 and later, use the following
command:
sw0# clear ssh-key SSH_server_IP_address
where
SSH_server_IP_address
is the IP address of the SSH server you want to
delete.
•
For Network OS devices running firmware version 2.1.1b, use the following
command:
sw0# execute-script sshdeleteknownhost
IP Address/Hostname to be deleted: SSH_server_IP_address
where
SSH_server_IP_address
is the IP address of the SSH server you want to
delete.
Firmware download using an external SCP
server does not work after reinstalling the
application or the external SCP server on the
Host machine. Clear the SCP server IP address or hostname from the known_hosts table of the device
using the following command:
sw0# FID10:root> ssh-keygen –R Host_Name
where
Host_Name
is the IP address or host name of the external SCP server.
