    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 :cool:

    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 ..

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

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

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

    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
    SCSI device sda: 312500000 512-byte hdwr sectors (160000 MB)
    sda: Write Protect is off
    sda: Mode Sense: 00 3a 00 00
    SCSI device sda: write cache: enabled, read cache: enabled, doesn't support DPO or FUA
    SCSI device sda: 312500000 512-byte hdwr sectors (160000 MB)
    sda: Write Protect is off
    sda: Mode Sense: 00 3a 00 00
    SCSI device sda: write cache: enabled, read cache: enabled, doesn't support DPO or FUA
    da: sda1 sda2 sda3 < sda5 > sda4
    sd 0:0:0:0: Attached scsi disk sda
    SCSI device sdb: 625142448 512-byte hdwr sectors (320073 MB)
    sdb: Write Protect is off
    sdb: Mode Sense: 00 3a 00 00
    ....
    ...
    etc.

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

    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
    Probing IDE interface ide0...
    hda: WDC WD2500JB-00REA0, ATA DISK drive
    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 .

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