IBM pSeries690 Delete Resource from Resource List, Disk Maintenance, Disk to Disk Copy

Delete Resource from Resource List

Use this task to delete resources from the resource list.

Note: Only resources that were previously detected by the diagnostics and have not

been deleted from the Diagnostic TestList are listed. If no resources are

available to be deleted, then none are listed.

Disk Maintenance

This service aid provides the following options for the fixed-disk maintenance:

vDisk to Disk Copy

vDisplay/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

for a procedure on migrating the contents of a physical

volume.

This publication is located on the

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. Toprevent corrupted data from being copied to the new drive, the service aid

stops if an unrecoverable read error is detected. Tohelp prevent possible problems with

the new drive, the service aid stops if the number of bad blocks being reassigned

reaches a threshold.

Touse 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.
