WANT TO MOVE BOOT LOGICAL VOLUME AND DUMP LOGICAL

ITEM: RTA000031491



QUESTION:                                                                       
                                                                                
I want to install a new disk drive in a 550 and use migratepv                   
to move all of the data from hdisk0 to the new drive.  I will                   
be removing the current hdisk0.                                                 
Today, hdisk0 contains the blv and dump logical volume, etc.                    
What steps do I need to take after the migratepv so that the machine            
knows the correct boot and dump devices?

A:     There is an excellent ASKQ item #5vpbn ("HOWTO AIX:  Avoiding            
Problems When Migrating Logical Volumes In The Root Volume Group                
Between Disks") that you should reference.  It will help you avoid              
any pitfalls while migrating data in the rootvg.  Basically, after you          
add the new disk to the volume group, you will need to issue the               
following commands:                                                             
                                                                                
1.   sysdumpdev -p /dev/sysdumpnull                                             
2.   migratepv hdisk0  hdiskx                                                   
3.   bosboot -a -u -d /dev/hdiskx                                               
4.   sysdumpdev -p /dev/hd7                                                     
5.   reducevg rootvg hdisk0                                                     
                                                                                
(NOTE:  hdiskx is the destination physical volume.)
