dsbitmap(1M)		System Administration Commands		  dsbitmap(1M)

NAME
       dsbitmap - size Availability Suite bitmap volumes

SYNOPSIS
       dsbitmap -h

       dsbitmap -p data_volume [bitmap_volume]

       dsbitmap -r data_volume [bitmap_volume]

DESCRIPTION
       The dsbitmap command calculates the size of the Availability Suite bit‐
       map volume required for use with the specified data volume.

OPTIONS
       The following options are supported:

       -h

	   Prints the usage message for the dsbitmap command

       -p data_volume [bitmap_volume]

	   For the given data_volume,  dsbitmap	 calculates  and  display  the
	   required  size  for the associated Availability Suite Point in Time
	   bitmap volume. The bitmap volume sizes for all possible  Availabil‐
	   ity	Suite  Point  in  Time set configurations are displayed. These
	   configurations include  Independent	shadow,	 Full  size  dependent
	   shadow, and Compact dependent shadow. If the optional bitmap_volume
	   argument is supplied, dsbitmap determines if this volume  is	 large
	   enough to be used as the bitmap volume for data_volume.

       -r data_volume [bitmap_volume]

	   For	the  given  data_volume,  dsbitmap calculates and displays the
	   required size for the associated Availability Suite	Remote	Mirror
	   bitmap  volume. The bitmap volume sizes for all possible Availabil‐
	   ity Suite Remote Mirror set	configurations	are  displayed.	 These
	   configurations  include  Sync  replication,	Async replication with
	   memory queue, disk queue and 32 bit	refcount.    If	 the  optional
	   bitmap_volume  argument  is	supplied,  dsbitmap determines if this
	   volume is large  enough  to	be  used  as  the  bitmap  volume  for
	   data_volume.

USAGE
       dsbitmap	 is typically used by the system administrator during the ini‐
       tial stages of configuring Sun StorageTek Availability  Suite  software
       in  order  to  determine	 the required bitmap volume sizes, and then to
       check if the bitmap volumes that have been created are suitable.

EXIT STATUS
       The following exit values are returned:

       0	    Successful completion. If the name of a bitmap volume  was
		    specified,	that  volume  is  sufficiently	large  for all
		    potential uses.

       1	    An error occurred.

       2	    An invalid option was supplied on the command line.

       3	    The specified bitmap volume is not large enough to be used
		    as an Availability Suite Remote Mirror bitmap for an asyn‐
		    chronous set with a disk queue, but is large enough to  be
		    used for all other Remote Mirror set configurations.

       4	    The specified bitmap volume is not large enough to be used
		    as an Availability Suite  Remote  Mirror  bitmap  for  any
		    Remote Mirror set configuration.

       5	    The specified bitmap volume is not large enough to be used
		    as an Availability Suite  Remote  Mirror  bitmap  for  any
		    Remote Mirror set configuration.

       6	    The specified bitmap volume is not large enough to be used
		    as an Availability Suite Point in Time bitmap for  a  com‐
		    pact  dependent shadow, but is large enough to be used for
		    all other Point in Time set configurations.
