Avamar Maintenance
Hello,
I have a question regarding Avamar maintenance window. Currently the maintenance window is configured between 9am and 7pm. Running the command STATUS.DPN I see the following:
Last checkpoint: took 33s (OK)
Last GC: took 2m 37s (OK)
Last hfscheck: finished after 12m 29s (OK)
I also see:
Maintenance windows scheduler capacity profile is active.
The maintenance window is currently running.
Currently running task(s): crunchwait
My question is how can I determine exactly how long maintenance is taking. I'm interested in decreasing the 10 hour maintenance window.
Thanks in advance.

Do you by chance have EMC's DPA?
you can get some good reports
I get this every day - the line will be RED if it fails. And I can see how long things are taking.

Unfortunately, I do not have EMC DPA. So I won't be able to leverage those reports.

I second using DPA for this. It's terribly easy to get these reports emailed to you daily, or to view/summary weekly/monthly trends.
With DPA, you could look at the length of your GC and HFScheck over a long period of time, and feel reasonably safe about reducing the window.
Let us know if that helps!

There is a support script called "sched.sh" that may do what you're looking for. The script prints a timeline of the last few days of maintenance, backups, replication, etc.. Here is some example output:
From the output, you can see that this test system is completing GC, checkpoints, and hfscheck within 30 minutes. You can also see that maintenance was missed on December 4 so if this were a production system, that would be something to look into.
You will likely need to pull the most recent version of the script down to your system because the one that ships with the software is somewhat out of date. The latest version of the script is available on the EMC FTP site.

I also vote for EMC DPA
I get the emails every day as well
And a Red line really stands out when a checkpoint fails
and it gave me a good idea of when and how long something runs
letting me schedules other activates better
there are also a number of other reports from Avamar I get.
like daily failures!
And it covers more then just Avamar. if you have other EMC equipment you might very easily talk management in to setting up DPA for use by your IT department.
