Only one of many servers is suffering poor performance with a nearline (Tier 2) storage system.
The server administrator has not discovered any obvious root cause. The server has multiple
paths to the storage system but only one path is active. Routine monitoring by the storage
administrator has determined that a single storage port has received a high number of bad frames.
What should the SAN administrator do?
Determine the source of duplicate frames.
Verify that the host ports are correctly zoned.
Find the source of frames with CRC errors.
Collect new performance data and compare to the baseline.
