Pb Installing Oracle 7.3 with AIX 4.2.1

I got a real problem in installing a new version of Oracle with my AIX BULL ESCALA T204. with AIX 4.2.1
I loose some files and it seems that they have 3 PTF and specialy one about problems with the logical volume manager. Is there anybody who had this problem?
I had Advnced Server for Unix 4.0 on my server and the 60GB are mirrored in RAID 1 with a DPT card manager... Received on Tue Mar 17 1998 - 00:00:00 CST
