Drive Parameters

Parameter

AbortStatus = 0xn

ALTOV = n

ARBTOV = n

Class = n

EDTOV = n

EnableDPC = n

FrameSizeMSB = n

HardALPA = 0xn

LinkTimeOut = n

LogErrors = n

Description

Values from 0x00 – 0xFF. Controls NT SRB error status for general Abort conditions. Default = SRB_STATUS_BUS_RESET (0x0E) which will not cause the current NT class driver to throttle down I/O performance after four of these errors have been received (on a per-LUN basis)

Values are in milliseconds from 1 to 15. Default = 15.

Values are milliseconds form 500 to 10000. Default = 1000. Represents FC_AL arbitration time-out prior to LIP.

Values from 0-2. Default = 2. Controls which Fibre Channel Class will be used: 0 = Class 1, 1 = Class 2, 2 = Class 3.

Values are in milliseconds form 500 to 10000. Default = 1000. Represents error detect time-out value prior to LIP.

Values 0 or 1. Default = 0. 0 = process I/O completion at interrupt level, 1 = process at DPC level.

Values from 1-8. Default = 8. Controls the upper byte of the receive FrameSize if issued in PLOGI. This lets the FrameSize to be constrained on 256 byte increments from 256 (1) – 2048 (8).

Values from 0x01 – 0xEF. Default = 0x01 lets the HBA use a hard assigned loop address. NOTE: Only valid ALPAs can be used (see Table 6-2).

Values are in seconds from 1 – 500. Default = 60. Controls the time-out at which link no longer BUSY’s requests but issues SELECTION_TIMEOUT error status.

Values 0 or 1. Default = 0. 0 = don’t log general HBA/drive errors. 1 = use Event Log to general errors.
