How do I determine which host is handling Optimizer?
I had a chat session with EMC support and they said my Optimizer keeps hanging because I don't have enough gatekeepers assigned to the host handling it, but the guy couldn't tell me which host he was talking about. I have a whole mess of hosts which have gatekeeper devices for various reasons (mostly due to SRDF being built into our clusters so the hosts need to be able to run symrdf commands), so I'm not sure which I need to add more to. Is there a way to determine which host is actually handling the requests?

Oh, no. I've never even heard of it. Let me take a look now.

Hmm... So, is Optimizer controlled entirely by the SP and no host is involved?

Do you have ECC installed in your shop?

Do you have a specific host that is used for storage management... a management host which would have Solutions Enabler installed on it?
That would be where I would suspect optimizer would also be running.

Trouphaz,
I may have another idea in how to identify Optimizer host.
Are you familiar with SymmAudit?
This may reflect Optimizer activity as well as the host from which it is running.
Let me know...

The Optimizer application runs on the SP, but you use your host to configure your run time parms, etc...

I have a host that I use, but we have a number of hosts that are available to use. The SRDF agent in Veritas Cluster Server requires Solutions Enabler be installed as well as the ability to run some symcli commands, though mostly symrdf. We also have our SMC server as well as the host that has our Symmetrix agent for ECC. Altogether, there are at least 10 different hosts that have access to manage disk (until we lock down symcli access anyhow).

Got another idea...
Use the symmaudit command again, but do not specify optimizer as the application.
We can see that optimizer was running on 5/09/2011, so use that date in the symmaudit command.
Let's see what host is accessing the array on that date.
# symaudit list -sid 123 -start_date 05/09/2011 -end_date 05/09/2011

Running out of ideas... do you have ECC installed on a host?

Yes. It is running on a different host than the one I've been running these commands on. The funny thing is if I could get EMC support to call me back this would likely be a non-issue.

I had to push the end date out to 5/10/2011 to get any data. I looked and saw a whole bunch of stuff, but almost all of it says "NONE" under host. The only lines that don't say none are the following:
dn005# symaudit list -sid 804 -start_date 05/09/2011 -end_date 05/10/2011 | grep -v NONE

So, one line says something on the Symmetrix and the rest show the host that we're running some symclone commands on in a scheduled script.

Sorry to hear the call back is slow...
So from what I've learned today, Optimizer can be managed from ECC/Ionix server, SMC server or Solutions Enabler server.
Don't know if that helps you narrow down your search...
If one of those servers did not have enough Gatekeeper devices I would expect issues with your other functions for those Applications.
Not sure if we are chasing the right grimlin... maybe support can help further.
Do you have a Service Request number?

I've got my support rep on it now, so I don't expect it will take much longer for a call back.
What it sounds like is that it isn't the systems that are trying to manage Optimizer, but instead the system that is handling the Optimizer requests. From what I've always understood, this is the SP itself within the DMX. Everything else is just used to change parameters and review configuration as you described earlier. We'll see.

Yep, thats why i dont think it's a gatekeeper issue...
By the way, if anything I helped with was useful, please take the time to mark replies appropriately, thank you very much.
keep me posted on your findings please.
Have a great evening

Hello Trouphaz,
Just curious if you got this issue resolved?
