Set timeout values for Linux guest operating systems

Contributors Netapp-shabaana

The guest operating system (OS) timeout scripts set the SCSI I/O timeout settings for versions 4, 5, 6, and 7 of Red Hat Enterprise Linux and versions 9, 10, and 11 of SUSE Linux Enterprise Server. You can specify either a 60-second timeout or a 190-second timeout. You must run the script each time you upgrade to a new version of Linux.

What you will need

You must have mounted the ISO image containing the Linux script.

Steps

  1. Access the console of the Linux virtual machine, and log in to an account with root privileges.

  2. Run the linux_gos_timeout-install.sh script.

    For Red Hat Enterprise Linux 4 or SUSE Linux Enterprise Server 9, a message similar to the following is displayed:

    Restarting udev... this may take a few seconds.
    Setting I/O Timeout (60s) for /dev/sda - SUCCESS!

    For Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6, and Red Hat Enterprise Linux 7 a message similar to the following is displayed:

    patching file /etc/udev/rules.d/50-udev.rules
    Hunk #1 succeeded at 333 (offset 13 lines).
    Restarting udev... this may take a few seconds.
    Starting udev: [ OK ]
    Setting I/O Timeout (60s) for /dev/sda - SUCCESS!

    For SUSE Linux Enterprise Server 10 or SUSE Linux Enterprise Server 11, a message similar to the following is displayed:

    patching file /etc/udev/rules.d/50-udev-default.rules
    Hunk #1 succeeded at 114 (offset 1 line).
    Restarting udev ...this may take a few seconds.
    Updating all available device nodes in /dev:   done

  3. Unmount the ISO image.
