 NAME
      irm - Internal RAID Manager

 SYNOPSIS
      /usr/sbin/irm

 DESCRIPTION
      The irm command starts a menu-driven Internal RAID Manager program
      (IRM) that makes it easy to perform configuration and management tasks
      for the A5856A RAID 4Si card.

      IRM discovers the RAID cards installed on an HP-UX system and allows
      the user to perform the tasks to configure or monitor the RAID logical
      drives.  Typically, IRM is used to configure the RAID logical drives,
      then sam(1M) is used to configure logical volumes and filesystems on
      the RAID drives.

      Context-sensitive help on the currently highlighted field is displayed
      in the lower portion of the screen.

    Running IRM
      IRM can only be run on text terminals.

      IRM requires superuser (user root) privileges to execute successfully.

    IRM Functional Areas
      IRM performs RAID administration tasks in the following areas:

      Configure Logical Drives

	   +  Create, modify, or clear the RAID card configuration.  One
	      option allows the user to allow IRM to automatically select an
	      appropriate RAID configuration for the set of disks attached
	      to the RAID adapter.  Note that the data stored on the logical
	      drives will be lost during these operations.  Use a safe
	      backup mechanism before modifying the configuration.

      Configure Objects

	   +  Perform various configuration tasks related to adapters,
	      logical and physical drives, SCSI channels, and the cache
	      policies associated with the battery backup.

      Rebuild Physical Drives

	   +  View or rebuild information about the physical hard drives.

      Check Consistency

	   +  Check the data consistency of the logical drives.	 This screen
	      provides information such as the logical drive number, the

	      RAID level, the size of the drive, the number of stripes and
	      the stripe size, and the drive state.

      Advanced Menu

	   +  Reconstruct a logical drive.

      Select Adapter

	   +  IRM operates on one RAID adapter at a time.  When multiple
	      RAID cards are installed in a system, be sure to choose the
	      card that you want to configure.	IRM displays the device file
	      of the card that is being configured in the upper portion of
	      the screen.

    Navigation
      In general, IRM requires the use of the cursor (arrow) keys to
      navigate between items, and the ENTER key to select an option.  Use
      the ESC key to cancel an operation and return to the previous menu.
      The top portion of the screen gives hints about how to navigate in a
      particular screen.
