    Hi all,

    Don't know if anyone can shed any light on our problem.

    We have made changes to the /etc/system file on an E10000 running Solaris
    64-bit.

    Issued a touch /reconfigure etc.

    For some reason the changes aren't being applied.

    sysdef and system listed below.

    Any ideas, am I missing something?.

    Thanks in advance,

    system:

    *ident "@(#)system 1.18 97/06/27 SMI" /* SVR4 1.5 */
    *
    * SYSTEM SPECIFICATION FILE
    *

    * moddir:
    *
    * Set the search path for modules. This has a format similar to the
    * csh path variable. If the module isn't found in the first directory
    * it tries the second and so on. The default is /kernel /usr/kernel
    *
    * Example:
    * moddir: /kernel /usr/kernel /other/modules

    * root device and root filesystem configuration:
    *
    * The following may be used to override the defaults provided by
    * the boot program:
    *
    * rootfs: Set the filesystem type of the root.
    *
    * rootdev: Set the root device. This should be a fully
    * expanded physical pathname. The default is the
    * physical pathname of the device where the boot
    * program resides. The physical pathname is
    * highly platform and configuration dependent.
    *
    * Example:
    * rootfs:ufs
    * rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a
    *
    * (Swap device configuration should be specified in /etc/vfstab.)

    * exclude:
    *
    * Modules appearing in the moddir path which are NOT to be loaded,
    * even if referenced. Note that `exclude' accepts either a module
    name,
    * or a filename which includes the directory.
    *
    * Examples:
    * exclude: win
    * exclude: sys/shmsys

    * forceload:
    *
    * Cause these modules to be loaded at boot time, (just before mounting
    * the root filesystem) rather than at first reference. Note that
    * forceload expects a filename which includes the directory. Also
    * note that loading a module does not necessarily imply that it will
    * be installed.
    *
    * Example:
    * forceload: drv/foo

    * set:
    *
    * Set an integer variable in the kernel or a module to a new value.
    * This facility should be used with caution. See system(4).
    *
    * Examples:
    *
    * To set variables in 'unix':
    *
    * set nautopush=32
    * set maxusers=40
    *
    * To set a variable named 'debug' in the module named 'test_module'
    *
    * set test_module:debug = 0x13

    * Begin MDD root info (do not edit)

    forceload: drv/sd
    forceload: drv/st
    forceload: drv/sg
    rootdev:/pseudo/md@0:0,10,blk
    * End MDD root info (do not edit)
    * Begin MDD database info (do not edit)
    set md:mddb_bootlist1="sd:23:16 sd:23:1050 sd:23:2084 sd:31:16 sd:31:1050"
    set md:mddb_bootlist2="sd:31:2084 sd:143:16 sd:143:1050 sd:143:2084"
    set md:mddb_bootlist3="sd:151:16 sd:151:1050 sd:151:2084"
    * End MDD database info (do not edit)

    * For sequential I/O performance set md_maxphys
    * The -tuneable- maximum IO size in bytes

    set md:md_maxphys=8388608

    * Insert any relevant Solaris settings here
    set fastscan=131072
    set handspreadpages=262144
    * this equates to 1/4 physical memory
    set maxpgio=1024

    set maxphys=1048576
