Fixing a Consistent Error with Multiple Drives on a Fibre
Channel Loop
Use the following procedure to determine if all of the drives on the Fibre Channel
have the problem:
1. Use a device driver utility (such as ntutil or tapeutil) to verify that the drive is
2. Determine the type of Fibre Channel topology that you are using.
3. Using this guide or the service guides of associated switch, hub, or fiber
4. Perform one of the following:
5. When the problem is corrected, restore all of the Fibre Channel cables to their

Fixing a Consistent Error in a Point-to-Point Topology

1. Ensure that the tape drive is powered ON.
2. Verify that the tape drive's serial number is the same as the drive serial number
3. Ensure that the drive is connected to the host or switch. The drive must be able
4. Run the Fibre Channel wrap test at the drive's Fibre Channel connector (see

(SAN) is experiencing problems.
v If the problem exists on a small number of drives, go to "Fixing a Consistent
Error with a Single Drive on a Fibre Channel Loop" on page D-55.
v If the problem exists with a large number of drives, perform the following
steps:
a. Disconnect all except one failing drive on the Fibre Channel.
b. Run the Fibre Channel wrap test to determine if a failure occurs on that
drive (see Function Code 6 in "Function Code 6: Run Host Interface Wrap
Test" on page D-32). If it does, perform the procedure in "Fixing a
Consistent Error with a Single Drive on a Fibre Channel Loop" on page
D-55.
c. Continue to connect one drive at a time to the Fibre Channel loop.
