Disk Signature Operation Command
For the disk signature operations, the iSMrc_signature command is used.
A disk signature is system information used for identifying the disk on the Windows system.
On the Windows system, two disks with the same signature cannot be used in the same
system. Data Replication automatically avoids the same disk signature when MV and RV
are synchronized. If a failure occurs during replication operations, a conflict may occur in the
disk signatures of MV and RV. In such a case, you can use the Disk Signature operation
command to restore them. To perform the disk signature operation, you can specify the disk
number to operate in units of disks, or you can operate all disks as targets.
