Disk to Disk Copy
This selection allows you to recover data from an old drive when replacing it with a new
drive. The service aid recovers all logical volume manager (LVM) software reassigned
blocks. To prevent corrupted data from being copied to the new drive, the service aid
stops if an unrecoverable read error is detected. To help prevent possible problems with
the new drive, the service aid stops if the number of bad blocks being reassigned
reaches a threshold.
Notes:
1. This service aid cannot be used to update to a different size drive. The service aid
only supports copying from a SCSI drive to another SCSI drive of similar size.
2. Use the migratepv command when copying the contents to other disk drive types.
This command also works when copying SCSI disk drives or when copying to a
different size SCSI disk drive. Refer to
System Management Guide: Operating
System and Devices
for a procedure on migrating the contents of a physical
volume.
