Alcatel Unleashed

All,

has anybody already done the upgrade from the 7.1 software release to the 7.2 on a Multi-chassis environment.

Does this upgrade generate a downtime, I've some doc were it states that with this upgrade we will have a downtime. What is the time frame of the downtime?

What are the experience with this new software release, is it stable or has it still some bugs in it.

I think I will need to plan a upgrade as we have some troubles to have HP QLOGIC network cards to connect to the system in MC-LAG setup (on one MC-LAG setup it is working, on the other we can't get it working), the servers stays in the reserved status when we check the linkag ports.

any comment would be much appreciated

I have no 10k but 6900s.
As the release notes state that you need a uboot update and this requires a reload
"Follow the steps below to upgrade the Image Files to 7.2.1.R02:
1. Reload the switch from the working directory.
OS10K-> reload from working no rollback-timeout
2. After the switch finishes rebooting, log into the switch.
...
..."

So i would plan a downtime, calculate for 30mins, so you have time to rollback to the former version if it fails.

It did not on my 6900 - downtime was 1 reboot ~4 Minutes, i think i was even able to upgrade one mc-lag peer after the other, so no real downtime in network, but i would not stress that, nobody is ever angry when you plan an outage and none happens..

I am running 7.2.1 on 6900 MC-Lag in my Lab, but this is no living environment. I have not encountered unusual behavoir so far.
because of the ability of having multiple mc-lag groups and standalone ports in vip vlan it may be worth to update.

Hi,

I have update both of our 10k Core boxes to 7.2.1.354RO2 and there will be brief downtime while the 10k are reloaded. The only other thing I noticed was the command changed in the VRRP from vrrp xx xx admin enable to vrrp admin-state enabled.

this changed prevented the vrrp instances from running, so I have to enable them all manually again, apart from that it worked fine.

Hope that helps ?

Sachy,

were your 10K switches configured in a MC-LAG setup

attached a doc on how to do a software upgrade of a Multichasis setup.

at this moment I didn't test this out yet as I don't get a approval for a downtime
