IBM T400F manual Fixing Intermittent Fibre Channel Errors

Fixing Intermittent Fibre Channel Errors

1.Determine the type of Fibre Channel topology that you are using (see page 6).

2.Ensure that the configuration and software levels are supported (see “Fibre Channel Attachment” on page 6).

3.Check that each Fibre Channel cable does not exceed 500 m (1640 ft).

4.Ensure that all Fibre Channel cables are installed correctly. Refer to the appropriate steps in Chapter 3, “Installing the Tape Drive” on page 13.

5.Using this guide or the service guides of associated switch, hub, or fiber products, determine that a problem exists between the drive, drive cable, and the device to which they attach. Try to isolate which part of the Storage Area Network (SAN) is experiencing problems.

6.Using this guide or the service guides of associated switch, hub, or fiber products, verify that the SAN configurations are correct (such as switch zoning for drive sharing).

7.Obtain all errors reported by the drive to the server (see “Using Sense Data” on page 71), then contact your OEM Product Application Engineer (PAE) for error analysis.
