Using stmsboot -d to Disable MPxIO Can Cause the System to Not Reboot Successfully (6923599)

When a Sun Blade Storage Module M2 is connected through the chassis to a supported Sun Blade server module using a Sun Storage 6Gb SAS REM HBA (SGX-SAS6-REM-Z), if you use "stmsboot -d" to disable MPxIO, the system cannot be rebooted successfully. The standby path is used as the boot path and you will not be able to mount the root filesystem. The recovery instruction to a previous STMS configuration will be printed on the console. This includes the root device name. The instructions reside in file /etc/mpxio/recover_instructions.


If you run into this issue, do the following:

  1. Boot from another boot device:

    • boot net


    • CD/DVD


    • Another disk which has the right OS image on it

  2. Use fsck access your root device and then mount your root device to a directory (for example: /mnt).

  3. Now you can restore the mpt_sas.conf and vfstab files using the cp command, and then use /usr/sbin/svccfg to recover.

    A sequence of sample commands are shown below, but remember that the timestamps are used for the backup files. Yours will be different. These are in the recovery instruction file and will be printed on the console.

    # cp /mnt/etc/mpxio/mpt_sas.conf.disable.2010_05_07_10_12 /mnt/kernel/drv/mpt_sas.conf
    # cp /mnt/etc/mpxio/vfstab.disable.2010_05_07_10_12 /mnt/etc/vfstab
    # /usr/sbin/svccfg -f /mnt/etc/mpxio/svccfg_recover
    # bootadm update-archive -R /mnt
