An existing 2-engine VMAX array has 192 x 450GB 15K Fibre Channel drives in a single
Virtual Provisioning pool. Two Linux database hosts are connected to the array and both are
running PowerPath. Host oradb01 is connected to the E0 FA ports on each director and is
meeting the customer performance SLA. Host oradb02 is connected to the G0 FA ports on
each director – and for the past 3 days this host has been experiencing poor performance
during peak activity in the afternoons. What steps do you take to identify likely bottlenecks?

A.
Run iostat -x in order to compare I/O size and read/write ratio of the two hosts

B.
Open a case with EMC Support and upload Oracle Statspack information

C.
Check the host for queued I/Os, use SPA to examine I/O size and utilization on the G0
FA ports

D.
Use SMC to check for Virtual Pool alerts, use SPA to measure drive response times
