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.

NAME
rdc.cf - Availability Suite Remote Mirror software configuration file DESCRIPTION
The rdc.cf is an optional configuration file that supplies the sndradm(1M) command with details of the volume sets to be operated on. Inrdc.cf, the volume sets and their host locations are defined in the following format: post pdevice pbitmap shost sdevice sbitmap protocol mode options The rdc.cf fields are: phost (primary host) Server on which the primary volume resides. pdevice (primary device) Primary volume partition to be copied. Specify only full path names (for example, /dev/rdsk/c0t1d0s2). pbitmap (primary bitmap) Volume partition in which the bitmap (scoreboard logs) of the primary partition is stored. Specify only full path names (for exam- ple, /dev/rdsk/c0t1d0s3). shost (secondary host) Server on which the secondary volume resides. sdevice (secondary device) Secondary volume partition. Specify only full path names (for example,/dev/rdsk/c0t1d0s4). sbitmap (secondary bitmap) Volume partition in which the bitmap (scoreboard logs) of the secondary file is stored. Specify only full path names (for example, /dev/rdsk/c0t1d0s5). protocol Network transfer protocol. Specify IP. mode Remote Mirror operating mode. Sync is the Remote Mirror mode where the I/O operation is not confirmed as complete until the remote volume has been updated. Async is the other Remote Mirror mode, in which the primary host I/O operation is confirmed as complete before updating the remote volume. options A consistency group name can be specified using the g character. A disk queue volume partition can be specified using the q character, using full path name only (/dev/rdsk/c0t1d0s5). Without the q character set will default to memory base queue. When running on a clustered system, a cluster resource group tag can be specified using the C character. These options have the following syntax: [g io_groupname] [q queue_volume][C ctag] Note - When running on a cluster configuration, the cluster resource group tag is appended to the Remote Mirror set by default.
