New DUMP file for LVM systems with LBA enabled drives
On March 4, 2002 IBM OS/2 Fix Distribution released a fix for systems using LVM and have LBA enabled drivers (usually one with greater than 8.3 GB physical size).
This APAR, PJ28457, fixes the problem with os2dump overwriting partitions on LBA-enabled systems. It is suggested that all users apply this fix.
There is a README file with install details in the DMP0304.ZIP
(ftp://service.boulder.ibm.com/ps/products/os2/fixes/v4.5warp/dmp0304.zip) file.
