Further Driver Parameters
irq1,irq2, etc. Only for RAID EISA Controllers with disabled BIOS (irq1, irq2,
etc. correspond with the IRQs of the RAID controllers)
disable:Y deactivates the RAID driver
disable:N activates the RAID driver
reserve_mode:0 reserves no SCSI devices*
reserve_mode:1 reserves all not-initialized removable hard disk drives*
reserve_mode:2 reserves all not-initialized SCSI devices*
reserve_list:h,b,t,l,h,b,t,l,... reserves SCSI devices at the corresponding coordinates with
h=Hostadapter, b=SCSI Bus, t=Target ID, l=LUN
reverse_scan:Y reversed scanning order of the PCI controllers
reverse_scan:N normal scanning order of PCI controllers according to the
system BIOS
max_ids:x x = number of target IDs per SCSI channel (accelerates the boot
process)
rescan:Y rescan all SCSI channels / Ids
rescan:N scan only those SCSI devices found during system power up*
* The driver parameters “reserve_mode” and “rescan:N” require Intel RAID Controller SRCU31s with
firmware version FW x.23.00 or higher.
The current default settings of the driver are:
•
“gdth=disable:N,reserve_mode:1,reverse_scan:N,max_ids:127,rescan:N.”
•
If “gdth” is loaded as a module, these parameters can also be added with a special syntax.
•
IRQ parameters are entered as “IRQ=” (for example, IRQ=10). Several parameters are not
separated with a comma (,””) but a space (“ “). All “:” are substituted with “=,” all “Y” with
“1” and all “N” with “0.”
•
Default: “modprobe gdth disable=0 reserve_mode=1 reverse_scan=0 max_ids=127 rescan=0.”
