En.02 Information Condition-Drive Missing; En.03 Information Condition-Drive Software Lock Active; En.04 Critical Condition-Loop A Drive Link Rate Incorrect - HP 6100 User Manual

If the EMU cannot determine the drive link rate, the EMU 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 drive 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 negotiation 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 elements is not required.
Complete the following procedure to correct this problem:
1. Record all six characters of the condition report.
2. Replace the defective drive with:
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 over temperature condition for another element.
This error remains active for one minute, or until the problem is corrected, whichever occurs
first.
Immediate correction is not required. However, correction cannot be delayed indefinitely.
Complete the following procedure to correct this problem.
1. Record all six characters of the condition report.
2. Remove 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 active
Some enclosures have a software-activated lock that prevents physically removing a drive while
this feature is active. This feature can be activated even when an enclosure does not have a physical
lock. 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.
0.1.en.04 CRITICAL condition—Loop a drive link rate incorrect
The drive is capable of operating at the loop link rate but is running at a different rate. For example,
the drive is operating at 1 Gbps, and the loop is operating at 2 Gbps. Only when the drive is
operating at the Fibre Channel link rate established by the I/O module can this drive transfer data.
