We need the ESXi host logs and SRM logs for the site the detach is failing.

The SRM report will in-detail tell you which host the detach has failed from.,

If you are using EMC Power Path/VE 5.7 then this could encounter the error you have mentioned,  check this VMware Knowledge Base You may see below error in logs.

SRM Test Failover cleanup operation times out and fails with the error: Cannot detach SCSI LUN. Operation timed out: 900 seconds.’

This is a known issue with Power path/VE 5.7 where it is not handling detached devices properly. You will need to update it to power path 5.7 P01
