Kernel Scsi Support

[BadFishBrewer]

How do i tell if my Kernel has scsi support already?

i am installing a scsi raid controller and i think the kernal needs that support
but i dont know how to tell if i need to re complie it.

thanks.

Current Kernel 2.4.20-31bigmem
RedHat 9.0

Thanks.

If you have the sources installed for your current kernel, you could cat the config file thus:


cat /usr/src/linux/.config | grep SCSI


and see what happens. Don't forget it's .config not config...

A vendor supplied kernel usually provides everything as either built in or modules. Put the card in - Kudzu should find it.

you were right, when i rebooted the system it did detect the array.

now when i run fdisk -l i get this.

so do i now need to apply a filesystem? if not then what should i do?

thanks.

Partiton it (fdisk /dev/sda) and hten make file systems on your partitions.

I'm not sure,
but your kernel will need the correct drivers loaded, eg I have
SCSI storage controller: LSI Logic / Symbios Logic 53c1010 Ultra3 SCSI Adapter (rev 2).
and
SCSI storage controller: Adaptec AIC-7861 (rev 1).

so in my kernel configuration I have:

CONFIG_SCSI=y
CONFIG_SCSI_AIC7XXX=m
CONFIG_SCSI_SYM53C8XX_2=y

Or from menuconfig

Device Drivers --->
SCSI device support --->
SCSI low-level drivers --->
<M> Adaptec AIC7xxx Fast -> U160 support (New Driver)
<*> SYM53C8XX Version 2 SCSI support

Then in my /etc/modules.autoload.d/kernel-2.6 I have:

aic7xxx

If you don't have the sources installed, you could try "less /proc/config.gz" - this only works if it has .config support enabled.
Wow, I never expected that this option might come in useful some day :)

Noticed that too. I hope I'm not a spelling Nazi, but I went ahead and corrected it.
