Installing PSP on DL 585 G2 - SAN Disks disappear

[Kennedy G. Doss]

We have a DL-585 G2 with EMC SAN Storage Attached to it. The OS running on this server is RHEL 5.3. I installed PSP 8.31 on this server (64 bit_). The installation went fine with no errors. But, on reboot, the server comes up to single user mode. It does not recognize any of the SAN Disks. I am sure PSP has messed up some kind of start sequence over here and that is not bringing up the EMC Disks. I can manually mount all the filesystems both belonging to the internal disks and external SAN Disks and the server is UP now. Did any one else face similar problems? Any input would be most appreciated.
