Create Snapshotvirtualdisk - Dell PowerVault MD3620f Command Line Interface Manual

Passwords are stored on each storage array in a management domain. If a
password was not previously set, a password is not needed. The password can
be any combination of alphanumeric characters with a maximum of 30
characters. (A storage array password can be defined by using the set
storageArray command.)
Synchronization priority defines the amount of system resources that are used
to synchronize the data between the primary virtual disk and the secondary
virtual disk 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 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.
Create Snapshot Virtual Disk
This command creates a snapshot virtual disk. When you use this command,
you can define the snapshot virtual disk in one of three ways:
• User-defined physical disks
• User-defined disk group
• User-defined number of physical disks for the snapshot virtual disk
If you choose to define a number of physical disks, the RAID controller
module firmware chooses which physical disks to use for the snapshot virtual
disk.
Syntax (User-Defined Physical Disks)
