IM&P Upgrade Steps during CUCM upgrade
I'm reading the upgrade guide, specifically, the time sequencing:

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/upgrade/11_5_1/cucm_b_upgrade-guide-cucm-115/cucm_b_upgrade-guide-cucm-115_chapter_010010.html

and it mentions upgrading the IM&P publisher (to inactive partition) at the same time as upgrading the subscribers. Then doing a switch version on the IMP pub at the same time as the CUCM subs.

Anyone do this parallel type upgrade before?

Sure would save a lot of time.

Re: IM&P Upgrade Steps during CUCM upgrade [ In reply to ]
This is what I do for an in-place upgrade with no other changes (hostname, IP address.. etc).

I do the cucm pub first (obviously), then imp pub (which is more like a cucm sub for upgrade purposes), then all the cucm and imp subs; everything into the inactive pt.

I do the pubs individually, then I’ll do a couple subs at a time .. etc.

Next I Switch version on the pubs; cucm, imp then the subs.

On the switch version, I wait till one node is fully up (tomcat started) before switching another.

May not be as efficient as it could be, but has kept me out of trouble thus far; plan your dive, dive your plan.

Re: IM&P Upgrade Steps during CUCM upgrade [ In reply to ]
Sweet. Thanks. I need to map out the window I have and see how this all fits in.

I really hate how the version compatibility is _so_ tight with the IMP cluster now. One more thing to have to worry about.

Oh well.

TAC just gave me some advice to see how long the DB replication would take after the switch version. Ahead of time, I do a “utils dbreplication status” and then “utils dbreplication runtimestate” until all tables show synced and take that time.

Does that sound about right?

Re: IM&P Upgrade Steps during CUCM upgrade [ In reply to ]
Lelio,



Are you apposed to upgrading the inactive partition during working hours? For my planning, the upgrade window starts when the bumps in service occur, which is usually the switch version.



There are some cases where the upgrade is not “online” there is a R1/R2 upgrade designation for this, where it is also upgrading the OS, but those are fairly rare.



Thanks,

-Nate

Re: IM&P Upgrade Steps during CUCM upgrade [ In reply to ]
I hear ya. I thought about that. But since we don’t do this very often, and we do have a window of opportunity, I wanted to take the safe approach.

I would hate to hit an undocumented feature that caused a service outage as part of upgrading the inactive partition.

Re: IM&P Upgrade Steps during CUCM upgrade [ In reply to ]
That’s the process I typically follow without issues.

Also, I can’t recall if this was posted here, but wanted to make sure you’ve seen the recent changes to resource requirements for IM&P. This may not apply to you if you have more than 5000 users.

IM&P VM resource requirements needs to be updated
CSCvk65006
Description
Symptom:
IM&P version 11.5.1.x or 12.0.1.x installed using one of the following configuration:
150 users (Full UC) 1vCPU 2 GB RAM
1,000 users (Full UC) 1vCPU 4 GB RAM
5,000 users (Full UC) 2vCPU 4 GB RAM

Customers with any of the above configuration might notice an increase use of CPU and Memory resources.

This can be fixed by manually increasing the resources according to the table below:
150 users (Full UC) 2vCPU 8 GB RAM
1,000 users (Full UC) 2vCPU 8 GB RAM
5,000 users (Full UC) 2vCPU 8 GB RAM

Conditions:
Performance Issues

Workaround:
Manually increase resources according to the table below:
150 users (Full UC) 2vCPU 8 GB RAM
1,000 users (Full UC) 2vCPU 8 GB RAM
5,000 users (Full UC) 2vCPU 8 GB RAM

If possible, it is recommended to have 4vCPU and 8 GB RAM as we are seeing more cases with high CPU due to resources related.

Re: IM&P Upgrade Steps during CUCM upgrade [ In reply to ]
In the words of the immortal Chris Farley….

holy schnikes

If possible, it is recommended to have 4vCPU and 8 GB RAM as we are seeing more cases with high CPU due to resources related.

They want 4 vCPU if possible? They think these things grow on trees? ????

Right now, our two IMP servers are at 2 vCPU and 4GB of RAM. (5000 user OVA).

I’ll have to see about coordinating this change as well. We don’t have a lot of capacity/activity on these servers, so I think we should be OK for now.

Funny thing – Bug updated May 20, 2019, but virtualization docs still show old OVA information.

That’s the process I typically follow without issues.


Also, I can’t recall if this was posted here, but wanted to make sure you’ve seen the recent changes to resource requirements for IM&P. This may not apply to you if you have more than 5000 users.


IM&P VM resource requirements needs to be updated
CSCvk65006
Description
Symptom:
IM&P version 11.5.1.x or 12.0.1.x installed using one of the following configuration:
150 users (Full UC) 1vCPU 2 GB RAM
1,000 users (Full UC) 1vCPU 4 GB RAM
5,000 users (Full UC) 2vCPU 4 GB RAM

Customers with any of the above configuration might notice an increase use of CPU and Memory resources.

This can be fixed by manually increasing the resources according to the table below:
150 users (Full UC) 2vCPU 8 GB RAM
1,000 users (Full UC) 2vCPU 8 GB RAM
5,000 users (Full UC) 2vCPU 8 GB RAM

Conditions:
Performance Issues

Workaround:
Manually increase resources according to the table below:
150 users (Full UC) 2vCPU 8 GB RAM
1,000 users (Full UC) 2vCPU 8 GB RAM
5,000 users (Full UC) 2vCPU 8 GB RAM

Anyone do this parallel type upgrade before?

Personally, I hate the fact that IM&P can’t be restarted without first disabling HA. So basically, if you have an unattended restart, you have to go in and make configuration changes.

Re: IM&P Upgrade Steps during CUCM upgrade [ In reply to ]
Actually, I prefer to disable IMP HA before installing in the inactive PT. This way, if you have to flip back to the other partition for some reason, IMP is already in an “HA disabled” state, which tends to make IMP recover a little better in my experience. Then just enable HA once everything is stable.

Thanks,

Ryan

Actually – I think that’s in the steps somewhere. I read that I think.

Actually, I prefer to disable IMP HA before installing in the inactive PT. This way, if you have to flip back to the other partition for some reason, IMP is already in an “HA disabled” state, which tends to make IMP recover a little better in my experience. Then just enable HA once everything is stable.
Thanks,

Ryan

Personally, I hate the fact that IM&P can’t be restarted without first disabling HA. So basically, if you have an unattended restart, you have to go in and make configuration changes.

Yuck.

Yeah, I HATE this bug. Why in the world can’t the docwiki or what ever it’s called be updated quicker than a bug be filed/made universally known, and who came up with these recommendations TAC or the BU.

But I have seem IMP just not start services, and adding resources magic fix it.

In the words of the immortal Chris Farley….

holy schnikes

If possible, it is recommended to have 4vCPU and 8 GB RAM as we are seeing more cases with high CPU due to resources related.

They want 4 vCPU if possible? They think these things grow on trees? ????

Right now, our two IMP servers are at 2 vCPU and 4GB of RAM. (5000 user OVA).

I’ll have to see about coordinating this change as well. We don’t have a lot of capacity/activity on these servers, so I think we should be OK for now.

Funny thing – Bug updated May 20, 2019, but virtualization docs still show old OVA information.

That’s the process I typically follow without issues.

Also, I can’t recall if this was posted here, but wanted to make sure you’ve seen the recent changes to resource requirements for IM&P. This may not apply to you if you have more than 5000 users.

IM&P VM resource requirements needs to be updated
CSCvk65006
Description
Symptom:
IM&P version 11.5.1.x or 12.0.1.x installed using one of the following configuration:
150 users (Full UC) 1vCPU 2 GB RAM
1,000 users (Full UC) 1vCPU 4 GB RAM
5,000 users (Full UC) 2vCPU 4 GB RAM

Customers with any of the above configuration might notice an increase use of CPU and Memory resources.

This can be fixed by manually increasing the resources according to the table below:
150 users (Full UC) 2vCPU 8 GB RAM
1,000 users (Full UC) 2vCPU 8 GB RAM
5,000 users (Full UC) 2vCPU 8 GB RAM

Conditions:
Performance Issues

Workaround:
Manually increase resources according to the table below:
150 users (Full UC) 2vCPU 8 GB RAM
1,000 users (Full UC) 2vCPU 8 GB RAM
5,000 users (Full UC) 2vCPU 8 GB RAM

If possible, it is recommended to have 4vCPU and 8 GB RAM as we are seeing more cases with high CPU due to resources related.

and it mentions upgrading the IM&P publisher (to inactive partition) at the same time as upgrading the subscribers. Then doing a switch version on the IMP pub at the same time as the CUCM subs.

Anyone do this parallel type upgrade before?

Sure would save a lot of time.
