Current parameters that can be set are listed in Table 6-1. Table 6-2 lists the
AL_PA addresses.
Table 6-1
Drive Parameters
Parameter Description
AbortStatus = 0xn
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)
ALTOV = n Values are in milliseconds from 1 to 15. Default = 15.
ARBTOV = n Values are milliseconds form 500 to 10000. Default = 1000.
Represents FC_AL arbitration time-out prior to LIP.
Class = n Values from 0-2. Default = 2. Controls which Fibre Channel
Class will be used: 0 = Class 1, 1 = Class 2, 2 = Class 3.
EDTOV = n Values are in milliseconds form 500 to 10000. Default =
1000. Represents error detect time-out value prior to LIP.
EnableDPC = n Values 0 or 1. Default = 0. 0 = process I/O completion at
interrupt level, 1 = process at DPC level.
FrameSizeMSB = n 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).
HardALPA = 0xn
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).
LinkTimeOut = n
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.
LogErrors = n Values 0 or 1. Default = 0. 0 = don’t log general HBA/drive
errors. 1 = use Event Log to general errors.
