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 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 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 Availability Suite Point in Time set configurations are  displayed.  These	configura-
	   tions  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  bit-
	   map	volume. The bitmap volume sizes for all possible Availability Suite Remote Mirror set configurations are displayed. These configu-
	   rations 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 initial 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  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 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 compact depen-
		    dent shadow, but is large enough to be used for all other Point in Time set configurations.

iicpshd(1M)						  System Administration Commands					       iicpshd(1M)

NAME

       iicpshd - copy Availability Suite Point-in-Time shadow volume

SYNOPSIS

       iicpshd [-s] old_shadow new_shadow...

DESCRIPTION

       The iicpshd command copies an Availability Suite Instant Image shadow volume, updating the bit map header and Availability Suite configura-
       tion to reflect the new shadow volume.

       No checks on the current use of either the old or new shadow volumes are made. The iicpshd command should only  be  run	when  the  Instant
       Image shadow set using the old shadow volume is suspended.

OPTIONS

       The iicpshd command supports the following option:

       -s	    Update  the  StorageTek  configuration  information for the Point-in-Time shadow set, but do not copy data from the old shadow
		    volume to the new shadow volume.

OPERANDS

       A iicpshd command line has the following operands:

       old_shadow new_shadow

	   iicpshd copies the data of the old Availability Suite Instant Image shadow volume to the new shadow volume  and  updates  the  bit  map
	   header and configuration data.

WARNINGS

       iicpshd	should be run only when the system is in single-user mode. When you run iicpshd, the command makes no attempt to check if a Point-
       in-Time set is in use. Running iicpshd with the -s flag while Point-in-Time is using the old shadow volume can result in shadow volume data
       loss. If you use the -s option, you must manually copy the data on the old shadow volume to the new shadow volume.
