CentOS - Mar 2006 - module kernel for adaptec 2110s in CenOS 4.2

Hi.

 

I''ve used ghost for change the ide disk for an array of scsi in raid
using
an adaptec controller 2110s.

 

Now when I boot it didn''t boot correctly. Looking for in Internet
(http://kbase.redhat.com/faq/FAQ_46_4969.shtm) I guest that I have to
rebuild the initial ramdisk to contain the proper kernel modules for the
adaptec controller. But what is the kernel module for 2110s in kernel 2.6.x?
I also have to adding a line in /etc/modprobe.conf, but I don''t know
the
format for that.

 

Thanks in advance.

 

Iago.

I don''t know the details about that controller, but you
should be able to boot the Centos install CD with
linux rescue
at the boot prompt and see what it loads.  Follow the
instructions to ''chroot /mnt/sysinstall'' when it tells
you to.  Then if you missed the ''loading ...'' during
bootup you can probably find the module name with
''lsmod''.  Add  a line like:
alias scsi_hostadapter aic7xxx
to /etc/modprobe.conf but with the correct module for your
adapter. Then run /sbin/mkinitrd with path and kernel
version numbers to replace your existing on.

Newer Adaptec RAID controllers usually use either aacraid or i2o_block 
driver (the DPT I2O based controllers).  If your''s is using aacraid, 
you''ll see the volumes as /dev/sd*.  If it''s using i2o_block,
than
you''ll see the volumes under /dev/i2o/hd*.  Try booting off 
installation CD into rescue mode and see what modules get loaded into 
the kernel.

Word of warning, i2o_block device driver seems to numerate drives in 
different order than BIOS, and depending how it is loaded it might 
numerate them differently (for example, I always get different order in 
rescue mode than when system is booted normally).  In some cases, 
you''ll need to instruct your boot loader what the BIOS thinks is the 
first drive (for example, I had trouble with LILO and this controller 
in the past because of that).
