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. For example,
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.
[Main Options]
For the iSMrc_signature command, you can specify the following options regarding Disk Signature
operation.
y Saving signature (-read)
Saves the disk signature recognized by the Windows system. Signatures are recorded in the
signature map file managed by the iSMrc_signature command.
y Writing signature (-set)
Restores the signature saved in the map file to the disk.
y Deleting signature (-del)
Deletes the signature saved in the map file.
y Initializing signature (-init)
Initializes the signature of the physical disk.
y Displaying the list of signature information (-list)
Displays a list of signatures saved in the map file and those saved in the disk array or displays the
signatures of the specified physical disk.
y Exporting signature to a file (-export)
Writes the signature information to the specified file.
y Importing signature from a file (-import)
Reads and registers the signature information recorded in the specified file.
