We recently encountered data corruption due to a broken SFP. Not sure on which end (VMAX or SAN switch) since both were replaced. There was no alert in SMC and even ESRS Call-Home was not triggered. After I opened a ticket the engineer could see the internal log of the VMAX and saw BB2D alerts.

We had luck since the error happened during a VMware installation so no data was lost. But now I am concerned that it could happen again and we have no way of getting alerted or at least to check ourselves if there are any errors. "symevent list" does not show anything related.

The remote support engineer and the CE on site had easy access to these log files. How can we see these log entries?

Thanks!
