• WhenthedriveisFibreChannel-compatible,theEMUcomparesthedrivelinkratewiththeI/O
module link rate, the loop link rate.
If the EMU cannot d etermine the drive link rate, the E MU activates the drive bypass function for one
minute. During this time the EMU continually checks the drive to determine the link rate.
• If the EMU determines the drive cannot operate at the Fibre Channel link rate set by the I/O
module, the drive bypass function ends and the drive is placed on the loop. This does not
generate a condition report.
• The EMU issues the condition report 0.1.en.01 when the drive link rate is incompatible with
Fibre Channel link rate.
• When the EMU cannot determine the drive link rate during the one-minute d rive bypass time, the
EMU places the drive on the loop. This process allows the drive to negotiate for an address.
• If negotiation indicates the link rates are compatible, the EMU rechecks the drive link rate to
verify compatibility.
• If neg otiation indicates the link rates are incompatible, an error condition exists and drive
loop data transfers stop.
This condition report remains active until the problem is corrected. The problem affects disk drive en.
Therefore, correction to prevent the possible failure of other elem ents is not required.
Complete the following procedure to c orrect this problem:
1. Record all six characters of the condition report.
2. Replacethedefectivedrivewith:
• A Fibre Channel-compatible drive.
• A Fibre Channel drive capable of operating at a link rate supported by I/O modules and
transceivers.
3. Observe the EMU to ensure the error is corrected.
4. If unable to correct the problem, contact your authorized service representative.
0.1.en.02 INFORMATION condition—Drive missing
The drive is improperly installed or missing. Either option could affect the enclosure air flow and cause an
overtemperature condition for another elem ent.
• This er
ror remains active for one minute, or until the problem is c orrected, whichever occurs first.
• Immediate correction is not required. However, correction cannot be delayed indefinitely.
Complete the following procedure to c orrect this problem.
1. Record all six characters of the condition report.
2. Remov
e and install the drive to ensure that it is properly installed.
3. Observe the EMU to ensure the error is corrected.
4. If removing and installing the drive did not correct the problem, install a replacement drive or a
drive
blank.
5. Observe the EMU to ensure the error is corrected.
6. If unable to correct the problem, contact your authorized service representative.
0.1.en.03 INFORMATION condition—Drive software lock a ctive
Some enclosures have a software-activated lock that prevents physically removing a drive while this feature
is a ctive. This feature can be activated even when an enclosure does not have a physical lo ck. Removing
a drive when this feature is active generates a condition report. This error remains active for 15 seconds.
No action is required to correct this condition.
