System Administration Commands                       dsbitmap(1M)



NAME
     dsbitmap - size Availability Suite bitmap volumes

SYNOPSIS
     dsbitmap -h


     dsbitmap -p datavolume [bitmapvolume]


     dsbitmap -r datavolume [bitmapvolume]


DESCRIPTION
     The dsbitmap command calculates the size of the Availability
     Suite bitmap 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 datavolume [bitmapvolume]

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


     -r datavolume [bitmapvolume]

         For  the  given  datavolume,  dsbitmap  calculates  and
         displays the required size for the associated Availabil-
         ity Suite Remote Mirror bitmap volume. The bitmap volume
         sizes  for all possible Availability 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
         bitmapvolume  argument is supplied, dsbitmap determines
         if this volume is large enough to be used as the  bitmap
         volume for datavolume.

System Administration Commands                       dsbitmap(1M)



USAGE
     dsbitmap is typically used by the system administrator  dur-
     ing the initial stages of configuring Sun StorageTek Availa-
     bility 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 suffi-
                  ciently 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 Mir-
                  ror bitmap for an asynchronous 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 Mir-
                  ror bitmap for any Remote Mirror set configura-
                  tion.


     5            The specified bitmap volume is not large enough
                  to be used as an Availability Suite Remote Mir-
                  ror bitmap for any Remote Mirror set configura-
                  tion.


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