Passwords are stored on each storage array in a management domain. If a password was not previously set, apassword is not needed. The password can be any combination of alphanumeric characters with a maximum of 30characters. (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 theprimary virtual disk and the secondary virtual disk of a replication relationship. If the highest priority level is selected, thedata synchronization uses the most system resources to perform the full synchronization, which decreases performancefor host data transfers.The writeOrder parameter applies only to asynchronous replications and makes them become part of a consistencygroup. Setting the writeOrder parameter to preserved causes the remote replication pair to transmit data fromthe primary virtual disk to the secondary virtual disk in the same order as the host writes to the primary virtual disk. Inthe event of a transmission link failure, the data is buffered until a full synchronization can occur. This action can requireadditional system overhead to maintain the buffered data, which slows operations. Setting the writeOrder parameterto notPreserved frees the system from having to maintain data in a buffer, but it requires forcing a fullsynchronization to make sure that the secondary virtual disk has the same data as the primary virtual disk.Create Snapshot Virtual DiskThis command creates a snapshot virtual disk. When you use this command, you can define the snapshot virtual disk inone of three ways:• User-defined physical disks• User-defined disk group• User-defined number of physical disks for the snapshot virtual diskIf you choose to define a number of physical disks, the RAID controller module firmware chooses which physical disksto use for the snapshot virtual disk.Syntax (User-Defined Physical Disks)create snapshotVirtualDisksourceVirtualDisk=”sourceVirtualDiskName”(repositoryRAIDLevel=(0 | 1 | 5 | 6)repositoryPhysicalDisks=(enclosureID1,slotID1enclosureID2,slotID2...enclosureIDn,slotIDn))[repositoryDiskGroupUserLabel=”repositoryDiskGroupName”enclosureLossProtect=(TRUE | FALSE)freeCapacityArea=freeCapacityIndexNumberuserLabel=”snapshotVirtualDiskName”warningThresholdPercent=percentValuerepositoryPercentOfSource=percentValuerepositoryUserLabel=”repositoryName”repositoryFullPolicy=(failSourceWrites |failSnapshot)]|enableSchedule=(TRUE | FALSE)|schedule=(immediate| snapshotSchedule)Syntax (User-Defined Number of Physical Disks)create snapshotVirtualDisksourceVirtualDisk=”sourceVirtualDiskName”repositoryRAIDLevel=(1 | 5 | 6)repositoryDriveCount=numberOfPhysicalDisks[repositoryDiskGroupUserLabel=”repositoryDiskGroupName”driveMediaType=(HDD | SSD | unknown | allMedia)]physicalDiskType=(SAS)enclosureLossProtect=(TRUE | FALSE)122
