Problem next in linux no scsi devices attached
lspci returns this

0a:01.0 SCSI storage controller: LSI Logic / Symbios Logic 53c1030 PCI-X Fusion-MPT Dual Ultra320 SCSI (rev 07)

but I can not discover in linux my Ulrium. What can I do or where I an check this?

Thank you all verry much in advance, this problem is important to me

Hi,

I would first check in the output of "dmesg" whether the tape drive was seen during startup...

Cheers,

Rob

if the drive is brand there is a chance of having factory default jumper setting which may have to be changed. Also check with the vendor any utility is availabale to scan and test the drive. IBM have one which i used when i had similar problem.

Any body knows can problem be in absence of proper driver?

on HP site writen that this SCSI controller not need any drivers. But on LSI site I found LSI Logic Fusion-MPT (TM)
(Message Passing Technology) device drivers for Linux(TM). Do I need to instal this? some one knows for what this driver is? As I reed there is kernel recomplinig needed. It's verry hard I think I will brake server OS :(((

thanks in advance

you need to check if the controller is seen by the Linux

cat /proc/mpt/summary

cat /proc/mpt/version

also

cat /proc/scsi/scsi will show devices..

You might need to load the drivers for the card.

Also the driver for the st drivers might need to be loaded

use modprobe st for tape devices

1) I donthave mpt dir at all.

cat /proc/mpt/summary
cat /proc/mpt/version

cat /proc/scsi/scsi
show

Attached devices:

Acording to HP no drivers needed, I am confused ^(((

st is loaded

Ok i have some achivements but I dont kno why and is they safe.

insmod mptbase return that i dont have mptbase

then I did

locate mptbase return is
/lib/modules/2.6.9-5.ELsmp/kernel/drivers/message/fusion/mptbase.ko
/lib/modules/2.6.9-5.EL/kernel/drivers/message/fusion/mptbase.ko

the I did insmod /lib/modules/2.6.9-5.ELsmp/kernel/drivers/message/fusion/mptbase.ko
and this is worked module is loaded

then i did the same for mptscsih and it worked too

no I have access to my TYPE but are my doings right? or i did completely unsafe?
