As feared, this is not a cake walk. The client picked up a Dell
Power Edge 2600 with 1G RAM 2.8GHz Xeon CPU, three 73G SCSI disks,
PERC4/Di RAID on the motherboard, Dell DLT tape drive, Dell slimline
CD & floppy drive on a single cable (not your standard PATA cable),
and Adaptec 39160 SCSI card.
The first plan was to install a IDE PCI controller in the available
32B PCI slot and connect a temporary PATA HD and DVD drive to
attempt a bare-metal restore of the Backup Edge bootable DVD media.
This of course failed as the PCI IDE card was a SATA RAID card with
PATA connector usable for two PATA drives. The card would boot a
PATA hard drive that I brought in and contained Windows 98. But if
I connected the IDE DVD/RW drive, the PCI SATA/PATA card would no
longer boot the PATA drive.
Plan 2: Fresh install of OS6 on the PERC RAID with an HP USB DVD
writer connected to the system during ISL. Then install Backup
Edge and dump the nightly backup media to a mounted /oldsys file
system and move data and programs as needed.
After downloading drivers from both SCO and Dell to create the
necessary (?) HBA driver disk for the PERC4/Di and booting
the SCO 6.0 installation CD and reading in the downloaded drivers,
all attempts to install on the PERC4/Di failed with the message
"no root disk found." (Driving home after 6 hours, I realized that I
had not tried the OS6 boot disk without additional HBA drivers.)
In desperation to get the new hardware up in advance of catastrophic
failure of the old system, I used the Dell BIOS and changed the
PERC4/Di ONMB setting from "RAID" to "SCSI" which allowed installation
of OS6 with the HBA drivers included on the OS6 installation CD
(as LSI MPT HBA).
On an Openserver 5.0.7 system I would now try btldinstall to add the PERC
drivers to the system and run mkdev hd to configure the kernel to
include the PERC drivers.
What is the equivalent steps on SCO 6.0?
Since the Dell PowerEdge 2600 has two SCSI channels that
can be configured as PERC4/Di RAID or LSI SCSI, I plan to move
the single disk on the first SCSI channel to the second channel,
reset BIOS from SCSI to RAID and reconfigure the kernel to add
the PERC4/Di drivers to the kernel.
Any suggestions, warnings, or other comments?
