Changing Boot Variables
You can replace the software images used to boot the VSM.
BEFORE YOU BEGIN
• Log in to the CLI in EXEC mode.
• Know the filenames of the pre-upgrade system and kickstart image files to apply.
DETAILED STEPS
Step 1 Display the current boot variables.
show boot
Example:
switch# show boot
sup-1
kickstart variable = bootflash:/nexus-1000v-kickstart-mz.4.0.4.SV1.3a.bin
system variable = bootflash:/nexus-1000v-mz.4.0.4.SV1.3a.bin
sup-2
kickstart variable = bootflash:/nexus-1000v-kickstart-mzg.4.2.1.SV1.4.bin
system variable = bootflash:/nexus-1000v-mzg.4.2.1.SV1.4.bin
No module boot variable set
switch(config)#
Step 2 Remove the current system and kickstart boot variables.
a. configure terminal
b. no boot system
c. no boot kickstart
Example:
switch# configure terminal
switch(config)# no boot system
switch(config)# no boot kickstart
switch#(config)#
Step 3 Restore the system and kickstart boot variables to the original pre-upgrade filenames.
a. boot system bootflash:system-boot-variable-name
b. boot system bootflash:kickstart-boot-variable-name
Example:
switch#(config)# boot system bootflash:nexus-1000v-mz.4.0.4.SV1.3a.bin
switch#(config)# boot kickstart bootflash:nexus-1000v-kickstart-mz.4.0.4.SV1.3a.bin
switch#(config)#
Step 4 Copy the running configuration to the startup configuration.
copy run start
Example:
switch#(config)# copy run start
[########################################] 100%e
switch#(config)#
Step 5 Verify the change in the system and kickstart boot variables.
show boot
