EMU Generated Condition Reports

■ ec is the error code
A direct correlation exists between the disk drive element number and the bay
number. However, no direct correlation exists between the disk drive bay number
and the device FC-AL physical address. The FC-AL physical address is assigned
by negotiation during system initialization.
The following sections define the disk drive error codes.
0.1.en.01 CRITICAL Condition
—
Drive Configuration, or Drive Link Rate
As each drive spins up and comes on-line, the EMU determines if the drive is
Fibre Channel compatible and can operate at the link rate (1 Gbps or 2 Gbps)
established by the I/O module. If either of these conditions are not met, the EMU
issues the condition report 0.1.en.01.
The corrective actions for these conditions are:
■ When the drive is not Fibre-Channel-compatible you must install a Fibre
Channel compatible drive or a drive blank.
■ When the drive is Fibre-Channel-compatible, the EMU compares the drive
link rate with the I/O module link rate, the loop link rate.
If the EMU cannot determine the drive link rate, the EMU activates the drive
bypass function for 1 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 drive link rate during the 1-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.
