Difference between disruptive and non-disruptive MDS9xxx upgrade

[b.e.leblanc]

Hi All,

I'm curious what the difference between a disruptive and non-disruptive upgrade (for both kickstart and system) on the MDS9xxx series fabric switches?

For example does a non-disruptive mean no reboot/reset is required?

Thanks in advance,

-Brian

The difference is that FC traffic wil be disrupted or not.

There may well be various module resets/reboots/failovers but FC traffic will not suffer.

As an example, I've just upgraded some 9148's they performed a reboot, causing me to loose my SSH session, but there was no disruption to FC traffic.

Thanks

Steven, thanks so much as that makes sense.  I just performed a non-disruptive on a lab switch.

Compatibility check is done:

Module  bootable          Impact  Install-type  Reason

------  --------  --------------  ------------  ------

     1       yes  non-disruptive         reset Compatibility check is done:
Module  bootable          Impact  Install-type  Reason
------  --------  --------------  ------------  ------
     1       yes  non-disruptive         reset 

The install-type said reset and I lost my SSH session so I was worried about doing such an upgrade in production because of the reboot.

Kudos!
