Nexus 9508 ISSU commands

[reilly.john]

I have a question on ISSU upgrade with the Cisco Nexus 9508 switches.  I read where after version 7.0(3)I3(1) ISSU is available.

Is there configuration commands in the CLI that need to be done to enable this feature?  I am reading through the upgrade guide but do not see any.

I am upgrading from 7.0(3)I1(3) up to 9.3(8)  following an upgrade path.  

Also the guide refers to patches must be installed if upgrading from 7.0(3)I1(3) to a later version.  I do not know where to find this patch to install.  

Any information would greatly be appreciated.

Thanks

Hi @reilly.john 

First, the commands for upgrading are like this:

Regular (disruptive) upgrade:      install all nxos bootflash:filename 

ISSU (non-disruptive) upgrade:   install all nxos bootflash:filename non-disruptive

Second, before you can upgrade to a supported ISSU image, you will need to install two patchs first. This is for 7.0(3)I1(3):

https://software.cisco.com/download/specialrelease/0f2015eebc7ea0d606441171b4a3baf2

Example how to install it:

• Add both patches with the install add bootflash:{patch-file.bin} command.

  switch(config)# install add bootflash:n9000-dk9.7.0.3.I1.3.CSCuy16604.bin
  switch(config)# install add bootflash:n9000-dk9.7.0.3.I1.3.CSCuy16606.bin
  

• Activate both patches with the install activate {patch-file.bin} command.

  switch(config)# install activate n9000-dk9.7.0.3.I1.3.CSCuy16604.bin
  switch (config)# install activate n9000-dk9.7.0.3.I1.3.CSCuy16606.bin
  

• Commit both patches with the install commit {patch-file.bin} command.

  switch(config)# install commit n9000-dk9.7.0.3.I1.3.CSCuy16604.bin
  switch (config)# install commit n9000-dk9.7.0.3.I1.3.CSCuy16606.bin
  

• Proceed with an NX-OS software upgrade to the desired target release with the install all command.

Last but not least, since anyway, any upgrade you are doing on the current version will be disruptive (with reload), why not upgrading directly to 9.3(8)?

Take care,
