Setting defaults for a virtual disk on a storage array

You can set the default options that apply to invidivual virtual disks.

To set defaults for a virtual disk on a storage array

  1. On the navigation bar, click Devices.

  2. Expand Storage Arrays, and then select the virtual disk that you want to view.

  3. In the task pane, under General Tasks, click Properties.

  4. On the Advanced tab, change the following information as appropriate:

    First threshold

    Type the first low disk space threshold at which you want Backup Exec to send an alert. You can change the value of the threshold, and you can change the amount of disk space to megabytes or gigabytes.

    When the amount of used disk space reaches this threshold, Backup Exec sends an alert. The default threshold is 75%, which is a percentage of the total available disk space on this virtual disk.

    Second threshold

    Type the second low disk space threshold at which you want Backup Exec to send an alert. You can change the value of the threshold, and you can change the amount of disk space to megabytes or gigabytes.

    When the amount of used disk space reaches this threshold, Backup Exec sends an alert. The default threshold is 85%, which is a percentage of the total available disk space on this virtual disk.

    Third threshold

    Type the third low disk space threshold at which you want Backup Exec to send an alert. You can change the value of the threshold, and you can change the amount of disk space to megabytes or gigabytes.

    When the amount of used disk space reaches this threshold, Backup Exec sends an alert. The default threshold is 95%, which is a percentage of the total available disk space on this virtual disk.

    Auto detect settings

    Check this option to let Backup Exec automatically detect the preferred settings for this device.

    Uncheck Auto detect settings if you want to set buffered reads or writes.

    The default setting is On.

    Buffered read

    Check this option in the following situations:

    • You do not want Backup Exec to automatically detect settings for this device.

    • You want this device to allow buffered reads, which is the reading of large blocks of data.

    If you enable buffered read, increased performance may result.

    The default setting is Off.

    Buffered write

    Check this option in the following situations:

    • You do not want Backup Exec to automatically detect settings for this device.

    • You want this device to allow buffered writes, which is the writing of large blocks of data.

    The default setting is On.
