  • 1.  0940-094 The capacity of this array exceeds the 1TB limit

    I was wondering if you could answer a question about 5703/11 Dual Raid controllers and 2104/DS4 disk subsystem?

    Our 2104/DS4 has twelve 300GB disk drives and we what to configure a RAID 5 as two 5+P arrays.

    However we get an error messages that says

    0940-094 The capacity of this array exceeds the 1TB limit

    This restricts us to three 3+P arrays. ;-(

    We have installed the lastest AIX 5.3 ML 4 patches and 5703/11 firmware (05 09007A 12/14/05) and 2104 DS4 firmware (F112).

    Any suggestions on how to work around the 1TB limitation or is this a restriction of AIX 5.3?

    Maximum PV size under AIX 32-bit kernel is 1TB, and under the 64-bit kernel it's 2TB, so switching kernels which is well documented elsewhere might be an option.

    Simon,

    We are running the 64 bit kernel.

    $ ls -l /unix
    lrwxrwxrwx 1 root system 21 Jan 20 00:55 /unix -> /usr/lib/boot/unix_64

    so what else could be limiting a RAID5 array on a 64 bit kernel to 1TB?

    Later,
    David

    Response from IBM:

    "Sorry, there is no work around, we do have a Line Item to increase the RAID
    limitation from 1TB to 2TB which is scheduled for 07/28/2006, but I think DASD
    support limit will be 8 300gb."

    Also, Simon said you could create a 2TB RAID with the 64-bit kerenl, but I think he was talking about doing a RAID in software with LVM.

    I had that same error this morning using smitty to build a RAID 5 array. I talked with IBM and they had me try building the array from the command line and that worked fine. They said I am downlevel on the firmware for our devices.pci and that is causing the smitty method to fail.
