Reference: Sun StorEdge 6130 Array Diagnostics
The following diagnostic options are available for the Sun StorEdge 6130 Array:
- Controller Read Test
- The Read Test initiates a read command as it would be sent over an I/O data path. It compares data with a known, specific data pattern, checking for data integrity and redundancy errors. If the read command is unsuccessful or the data compared is not correct, the controller is considered to be in error and is failed.
- Controller Write Test
- A Write Test initiates a write command as it would be sent over an I/O data path (to the Diagnostics region on a specified drive). This Diagnostics region is then read and compared to a specific data pattern. If the write fails or the data compared is not correct, the controller is considered to be in error and is failed and placed offline.
- Internal Loopback Test
- The Internal Loopback Test passes data through each controller's drive-side channel, out onto the loop and then back again. Enough data is transferred to determine error conditions on the channel. If the test fails on any channel, then this status is saved so that it can be returned if all other tests pass.
- All Controller Tests
- All controller tests are run.
