NAME

       scsimgr_estape - SCSI class driver estape plug-in for scsimgr

DESCRIPTION

       The  SCSI  class  driver  plug-in for implements management and diagnostic operations specific to classes of devices bound to driver is the
       native HP-UX SCSI class driver that handles, by default, all tape devices.

       The plug-in handles the following operations for driver estape:

	  o Display and clear driver global statistics and the statistics it maintains on instances of LUNs bound to it, and on related LUN paths.

	  o Display status and other information maintained by driver on LUNs bound to it.

	  o  Get, set and save driver global and per-lun instance attributes.

   Commands
       The user can explicitly send the following scsimgr commands to driver plug-in by specifying the

	  Clears statistics.

	  Displays information on attributes.

	  Displays status and other information.

	  Displays statistics.

	  Saves value of attributes in a persistent store.

	  Set current values of attributes.

       Note: Refer to scsimgr(1M) for syntax of the above commands.

       However, the only instances where it is necessary to explicitly send a command to the plug-in is  when  performing  operations  on  objects
       global to driver global statistics, attributes or status information.  In all the other cases, automatically invokes the plug-in to perform
       the driver specific part of the operation, when the operation applies to LUNs bound to driver estape or to their LUN paths.

   Attributes
       The following table lists driver estape specific attributes.  For details on the concept of attribute refer to scsimgr(1M).

       Note: The following conventions are used:

	  o RO is Read Only.
	  o RW is Read Write.
	  o VBM is Variable Block Mode.
	  o uint32 is unsigned 32 bits integer.
	  o uint64 is unsigned 64 bits integer.
	  o Range of values for applicable attributes is listed.

   I/O Load Balancing and Multi-Pathing Policies
       The driver does not support load balancing and has minimal support for multi-pathing.

       When  the device is first opened after a system boot, a path is chosen and will remain fixed.  If the path fails, the next open will pick a
       new path.
