Thanks for your response.
I have requested them to use the manual collection by changing the delivery method to invoke the archives but they are not agreeing as they need to get approvals from their management and this is the way they are collecting the Perf archives from so many days.
Using one collect to trigger the archives and collecting the dump from the location and uploading them to upload.netapp.com/sg and it is working another cluster and the problem is with this cluster which is not working in the same way. Today I monitored a P1 case(2009042635) for the same customer but a different cluster and the one collect collection worked here. So wanted to know whats wrong with this cluster and log collection.
Thanks a lot for your time for looking into this .
