Disk Maintenance
This service aid provides the following options for the fixed-disk maintenance:
v Disk to Disk Copy
v Display/Alter Sector
Disk to Disk Copy
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.
This publication is located on the
AIX V4.3 Documentation
CD. The documentation
information is made accessible by loading the documentation CD onto the hard disk
or by mounting the CD in the CD-ROM drive.
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.
To use this service aid, both the old and new disks must be installed in or attached to
the system with unique SCSI addresses. This requires that the new disk drive SCSI
address must be set to an address that is not currently in use and the drive be installed
in an empty location. If there are no empty locations, then one of the other drives must
be removed. When the copy is complete, only one drive can remain installed. Either
remove the target drive to return to the original configuration, or perform the following
procedure to complete the replacement of the old drive with the new drive:
1. Remove both drives.
2. Set the SCSI address of the new drive to the SCSI address of the old drive.
3. Install the new drive in the old drive’s location.
4. Install any other drives (that were removed) into their original location.
