Dell PowerVault MD3060e Series, Руководство CLI

Страница: 179 / 226

Parameter Description
writeMode This parameter defines how the primary virtual disk writes
to the secondary virtual disk. Valid values are
synchronous
or
asynchronous
.
Notes
When using this command, one or more of the optional parameters can be specified.
Synchronization priority defines the amount of system resources that are used to synchronize the data between the
primary virtual disks and the secondary virtual disks of a replication relationship. If the highest priority level is selected,
the data synchronization uses the most system resources to perform the full synchronization, which decreases the
performance for host data transfers.
The
writeOrder
parameter applies only to asynchronous replications and makes them become part of a consistency
group. Setting the
writeOrder
parameter to
preserved
causes the remote replication pair to transmit data from
the primary virtual disk to the secondary virtual disk in the same order as the host writes to the primary virtual disk. In
the event of a transmission link failure, the data is buffered until a full synchronization can occur. This action can require
additional system overhead to maintain the buffered data, which slows operations. Setting the
writeOrder
parameter
to
notPreserved
frees the system from having to maintain data in a buffer, but it requires forcing a full
synchronization to make sure that the secondary virtual disk has the same data as the primary virtual disk.
Set Session
This command defines how you want the current script engine session to run.
Syntax
set session errorAction=(stop | continue)
password=” storageArrayPassword ”
performanceMonitorInterval= intervalValue
performanceMonitorIterations= iterationValue
Parameters
Parameter Description
errorAction How the session responds if an error is encountered
during processing. You can choose to stop the session if
an error is encountered, or you can continue the session
after encountering an error. The default value is stop.
(This parameter defines the action for execution errors,
not syntax errors. Some error conditions might override
the continue value.)
password The password for the storage array. Enclose the password
in double quotation marks (“ ”).
performanceMonitorInterval The frequency of gathering performance data. Enter an
integer value for the polling interval, in seconds, for which
you want to capture data. The range of values is 3 to 3600
seconds. The default value is 5 seconds.
performanceMonitorIterations The number of samples to capture. Enter an integer value.
The range of values for samples captured is 1 to 3600. The
default value is 5.
