The OS administrator in your company informed you about the upgrade of storage to new disk
controllers and hard disks. You want to test if the new I/O devices are capable of handling the I/O
load. The database is using Automatic Storage Management(ASM) for storage. To test the
throughput and other I/O metrics, you performed IO calibration from the Enterprise Manager but
you notice that the IO calibration job failed.
