A shaded element does not generate a condition report. However, for any error, you should record the error code. Then,
implement the recommended corrective action.
Drive conditions
The format of a disk drive condition report is 0.1.en.ec,where:
• 0.1. is the
disk drive element type number
• en. is the two-character disk drive element
• ec is the error co d e
Adirectc
orrelation exists between the disk drive element number and the bay num ber. However, no
direct correlation exi sts between the disk drive bay number and the device FC-AL physical add ress. The
FC-AL physical ad dress is assigned by ne gotiation during system initialization.
The following sections d efine the disk drive error codes.
0.1.en.01CRITICALcondition—Driveconfiguration 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 (1Gbps or 2G bps) established by the I/O mo dule. 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 d rive is not Fibre Channel-compatible you must install a Fibre Channel compatible
driveoradriveblank.
• When the drive is Fibre Channel-compatible, the EMU compares the drive link rate with the I/O
modulelinkrate,thelooplinkrate.
If the EMU cannot determine the drive link rate, the EMU activates the drive bypass function for one
minute. D uring this time the EMU continually checks the d rive to determine the link rate.
