I am attempting to install RedHat 6.2 on the following system:
Sun E250 with
   1 GB RAM
   Ultra Wide SCSI
   2 18GB drives
   2 Sparc CPU's (400mhz)

Server installation.

Staic IP addresses (2 ethernet interfaces)

I am setting the following partitions using disk druid (not fdisk):
    /            750 MB  /dev/md0
    /usr        1200 MB  /dev/md1
    /home       1200 MB  /dev/md2
    /opt        1200 MB  /dev/md3
    /usr/local  1200 MB  /dev/md4
    <swap>      1048 GB  /dev/md5

Everything runs fine until the very end where it hangs on "performing post 
install configuration" every time. The only way I can get it to complete 
the install is to set it up without the RAID (md) devices.
