Troubleshooting Cisco SAN-OS Software System Reboots
The switch(boot)# prompt indicates that you have a usable Kickstart image.
Step 4 Issue the init system command at the switch(boot)# prompt.
switch(boot)# init system
Caution Be sure that you have made a backup of the configuration files before you issue this command.
Step 5 Follow the procedure specified in the “Recovery from the switch(boot)# Prompt” section on page 2-21.
Recovery from the switch(boot)# Prompt
To recover a system image using the kickstart image for a switch with a single supervisor module, follow
these steps:
Step 1 Change to configuration mode.
switch(boot)#config t
switch(boot)(config)#
Step 2 Follow this step if you issued an init system command. Otherwise, skip to Step 3.
a. Issue the ip default-gateway command to configure the IP address of the default gateway.
switch(boot)(config)#ip default-gateway 209.165.200.226
b. Configure the IP address of the mgmt0 interface.
switch(boot)(config)#interface mgmt 0
switch(boot)(config-if)#ip address 209.165.200.227 255.255.255.0
Step 3 Issue the no shutdown command to enable the mgmt0 interface on the switch.
switch(boot)(config-mgmt0)# no shutdown
Step 4 Enter end to exit to EXEC mode.
switch(boot)(config-mgmt0)# end
Step 5 If you believe there are file system problems, issue the init system check-filesystem command. As of
Cisco MDS SAN-OS Release 2.1(1a), this command checks all internal file systems and fixes any errors
that are encountered. This command takes considerable time to complete.
switch(boot)# init system check-filesytem
Step 6 Copy the system image from the required TFTP server.
switch(boot)# copy tftp://172.16.10.100/system-image1 bootflash:system-image1
Step 7 Copy the kickstart image from the required TFTP server.
switch(boot)# copy tftp://172.16.10.100/kickstart-image1 bootflash:kickstart-image1
Step 8 Verify that the system and kickstart image files are copied to your bootflash: file system.
switch(boot)# dir bootflash:
