AIX 5.2 Migration

[garry1624]

I did a AIX 5.2 migration from 4.3 Ml_10. One problem I am dealing with is SAN disks.
The system has ESS storage i.e vpaths hdisks etc and after the miration
process the system did come back with Volume Groups and filesystems, however the VG's which should show vpaths, show only one hdisk.

I know of a procedure to fix this. i.e
Delete hdisks, vpaths etc, run cfgmgr, hd2vp etc, however the hd2vp fails with this message

hd2vp vg1
vg1
vg1 contains these hdisks and pvids

Can not map hdisk2 to a dpo vpath device.

Also the cfgmgr comes back with this error message

Method error (/usr/lib/methods/cfallvpath -2):
0514-038 Error loading kernel extension.
Method error (/usr/lib/methods/scsimap >> /var/adm/essmap.out):

customized device configuration database.
