FSA - RecallLimitMaxRecalls on EMC Celerra
All
We recently migrated from Windows Server to a EMC Celerra box. We use the CIFS share.
By default on a windows server you have a limit of 20 recalls in 10 seconds (http://www.symantec.com/business/support/index?page=content&id=HOWTO56315#id-63347)
Our working requirement required us to change this limit from 20 to 1000 files recalls which was very easy to do as it required a change in the registry of the fileserver which havs the placeholder services running.
Now that we have migrated to EMC Celerra I cannot find any method of change this limit. I have contacted support and they have said this is not possible.
Could one of you experts guide me in the right direction or confirm this is not possible on a Celerra box and what could be possibily a work around.
Many Thanks

You sum it up pretty nicely
You sum it up pretty nicely and there really isn't much to explain.
Did you try pass-through recall? Reading through the technote and related docs it seems it will help and really at this time it is your only option unless you want to migrate off the Celerra back to NTFS.

If Support says this is not
If Support says this is not possible they probably will be right.
It will be very hard to add a registry entry in a Celerra :-)
If this response answers your concern, please mark it as a "solution"
Do you use Pass-Through
Do you use Pass-Through Recall? Pass-Through recall by default does not limit the number of recalls.

Thanks Tony - I sent the link
Thanks Tony - I sent the link to support and asked them if this will solve my issue. There response was this
"As per discussion the pass through recall is used when you have free disk space crunch on the Celerra and also reduce recall times for large files. This depends on the read/write operation triggered by the user. This setting will not serve the purpose you are looking for. However you can give a try and check if this improves the situation."
Let me explain what we have.
We use EMC Celerra as our file system, here we have millions of jpegs which are archived using EV FSA. The files get archived off to EMC Centera and placeholders are left behind. We run some code on our linux boxes which sometimes require read 1000s of jpegs/files within seconds. At this point we get errors as I think we reach a recall limit. When we had windows as our file system we fixed the issue by changing the recall limit.
Can you please shed some more light on this
Thanks
