PROBLEM: (82270) (PATCH ID: OSF520-910)
********
When the user chooses the Advanced mode of restore in the btextract
for a system with LSM on, prior disk information will not be used.
Also, for LSM configuration, one must specify the LSM volume in the 
disk partition. User will not be prompted to choose the lsm disk partition
at the time of the advance restore mode. Where as in case of the DEFAULT
mode, the previous disk label informations are used and configured 
accordingly and hence LSM configuration would be proper. Now it is taken
care to prevent the "advanced" mode of restore for the sysetm with LSM 
configuraion.
