SCSI argument list

max scsi luns

Some SCSI devices are poorly designed and will lock up

when probed for LUNs (Logical Unit Numbers) other

than zero. As the kernels now default to only probe

LUN 0, this argument allows for the probing of other

LUNs as well.

st=

This is used to configure SCSI tape devices and has the

form: st=buf size[,write threshold[,max bufs]].

buf size:

The value is given in units of kilobytes with the default

value of 32 and a max value of 16384.

write threshold:

Is the size of the buffer that will commit a write to tape

and defaults to 30 kilobytes.

max bufs:

Normally defaults to 2 but the proper number depends

on how many devices are present.

aha152x=iobase[,irq[,scsi id[,reconnect[,parity]]]]

These values are as described earlier and are order depen 

dent, so to specify parity, the rest of the parameters must

appear on the line. If the reconnect value is non zero

the device will be allowed to disconnect/reconnect.
