LINK_DOWN_AUTO

SUSPEND=

When this switch is enabled, the DR replication is automatically suspended if the link bet ween the arrays

goes down. It will stay suspended even if the link returns. The possible values are: ENABLED or DISABLED.

MAX_LOG_SIZE=

This is the maximum size for the D R log disk. The value is the number of blocks in 512 bytes. If left

blank or set to "0", the controller ﬁrmware will calculate the best log size for the space available.

Otherwise, you can specify a size, which must be bet ween 136MB and 2TB entered in blocks: 278528

through 4294 96 7 296.

NOTE:

If you specify a size that is larger the available di s k space, the command will complete successfully, a nd

the DR Group will be created (even though the space is not available) . If additional disks are added to

the conﬁguration, the controller will allocate more data for the DR log.

NOFAILSAFE

This is the default when you ﬁrst create the DR G roup. When the connection between the source and

the destination array fails, writes are directed to the log u ntil the connection is restored. When the

connection is restored, the pending destination writes are pushed across to the d estination array. If the

log becomes full, the array makes a full c opy of the source virtual disk to the destination virtual disk when

the connection is restored. Otherwise, the log resynchs the source and destination virtual disks.

NAME=

This is the new name for the speciﬁed DR Group.

SUSPEND

This op tion stops replication of data from the source to the destination. This causes the same behavior as

if the connection failed.

NOSUSPEND

This option allows replication of da ta from the source to the destination to resume. This causes the

same behavior as if the connection was restored.

WRITEMODE=

This option deﬁnes the I/O interaction between the destination a nd source side. Possible values are

synchronous and asynchronous.

Example

SET DR_GROUP “\Data Replication\Transactions” SUSPEND

This exa mple suspends replication for the DR Group Transactions.

SET DISK

The SET DISK command changes the properties of a disk.

Syntax

SET DISK <name>
