Batch runs 6hours late after SAN switch

Hi,

We moved to a new SAN on Wednesday and after that we have seen some poor performance during our nighly batch runs. I have uploaded a statspack report from the start of the batch until the time is was almost finished.

I see a lot of 'read by other session' but they did not occur until around 11:00AM.

Any ideas why my batch runs 6hours late?

Regards
