LINK_DOWN_TOUT

Minimum value = 0, maximum value = 65536 (decimal). Default = 60;

This parameter specifies the maximum time, in seconds, for a link to remain down prior

to beginning to return I/O requests in error. Use a value of zero to never timeout I/O

requests when the link is down. Events such as cable disconnects can cause the link to

be down indefinitely. Events such as drive removal/insertion only cause the link to be

down only briefly. The default value should be satisfactory for most cases.

/LUN

Boolean parameter: 0 = off, 1 = on. Default is /LUN=0;

If this parameter is turned off (default), access is restricted to LUN 0 of any multi−LUN

device. When this parameter is turned on, multi−LUN support for the Emulex

LightPulse PCI Fibre Channel Adapter driver is activated. See MAX_LUN below.

MAX_LUN

Minimum value = 1, maximum value = 256 (decimal). Default = 8;

MAX_LUN determines the number of LUNs supported per device. This is important for

RAID arrays. This value is required if /LUN is set to 1 (turned on). The value is

dependent on the array configuration.

MAX_QDEPTH

Minimum value = 1, maximum value = 64 (decimal). Default = 16;

MAX_QDEPTH controls the number of commands that can be issued at one time to

each LUN before automatic throttling occurs. The default value should be satisfactory

for most cases.
