SATA Drives

[CompufixHosting]

Maybe someone here can help me with this problem,

I installed 2 SATA raptors drives on my server. I formatted/partitioned one of the drives through WHM. After rebooting both drives disappeared. They are still detected within the BIOS but not in CentOS. It is possible that I installed a wrong driver or made a bad configuration change.

Server Info:

CentOS 4.6 64bit
cPanel/WHM
Motherboard: http://www.supermicro.com/products/m.../X6DVL-EG2.cfm
OS is running on a 250GB IDE drive
2 SATA WD Raptors (That I am trying to get to work)


Any help would be greatly appreciated.

Thanks

CompufixHosting ,

if you would post the output of /sbin/fdisk -l , it will really help to determine what kind of issue you have. we need to know how many HD and partitions are there ..

in general , when you make a partition, you have to make a mount point and mount the partition to it .

BTW, I have never formatted/partitioned through WHM. I usually do them using command lines. if you need help doing so, just ask

There is only one hard drive which is /dev/hda = 250 GB
Your system don't recognize the additional hard drive.

it will be helpful if you post the output of dmesg | egrep 'sd[a-d]?'
it should print out the bootup messages that is related to sata hard drive ..

[CompufixHosting]

That command did not come back with anything when I typed it in.

I typed dmesg | egrep 'sd[a-d]?'

[CompufixHosting]

However here is the whole dmesg log:

Well, I know they are connected properly as they are seen in the BIOS and have previously worked.

[SecFilterEngine]

the way I see it now is that the kernel don't see/recognize sata hard drive at all. The reason I can think of is that they probably are not connected to/installed on the machine correctly . I would double check that before I go any further.

In general , when the hard drive is connected to the machine correctly , it will show up in the boot log , here is an example of my own machine :

[root@localhost ~]# dmesg | egrep 'sd[a-d]?' | head -30

etc.

I wish I could help you more, but I hope the above information is helpful.

Well, I know they are connected properly as they are seen in the BIOS and have previously worked like a week ago.

I received the following msgs when upgrading the kernal:

WARNING: No module aarich found for kernel 2.6.9-67.0.1.EL, continuing anyway
WARNING: No module aar81xx found for kernel 2.6.9-67.0.1.EL, continuing anyway
WARNING: No module adpahci found for kernel 2.6.9-67.0.1.EL, continuing anyway


Not sure if it has anything to do with this problem.

Suprisingly after upgrading the kernal and rebooting the drives are now detected. Now what would be the best way to create a software RAID? Or would you recommend just using the drives seperatly?

hey :

I just notice that you post the boot log : Here was your issue :

divert: not allocating divert_blk for non-ethernet device lo
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx

ide1: I/O resource 0x170-0x177 not free.
ide1: ports already in use, skipping probe

google it ! I found many people had the same issue when they have IDE and SATA hard drive in the same machine . it seems to me that it was an issue and it has already been fixed in the last kernel release .

HTH .

it really depends on what you need them for ..

I am going to use the raptors for customer data and use the 250GB IDE for backups.
