Folks,

 

Well I seem to be running around in circles. As it takes most of a weekend
to back up the P390 because of various things, I decided there must be a
quicker way. And there is!

 

1.      Set up SD card in SCSI2SD as a single disk physical rather than
split to match the config on the RAID array. I still have the same number of
partitions but they are all on one LUN.
2.      SD card can now all be seen by windows but as most partitions a HPFS
I can't mount them but I can use MS's DISK2VHD to image the card.
3.      Install OS/2 in a VirtualBox and I can now mount the HPFS partitions
4.      ZIP up drives and FTP to NAS box. Both are on same gigabit LAN so
its fast.

 

So I can now back up the server in a morning. Just need to script it and
test restore.

 

Dave.

Folks,            

 

Well in case any one has the slightest bit of interest, I have now plugged
the RAID card back in and after replacing on of the drive carriers I can get
five of the six drives to spin up. Its now copying stuff to my Buffalo NAS
but as its 10Mbit LAN its not terribly fast. I think the NAS isn't very fast
either. It looks like zipping up the files and FTPing the ZIP files might be
the quickest way to go.

I thought I had captioned that picture. It's the original RAID controller
which I am not using. If I plug it in it starts the disks in the RAID array
which takes ages, and steals the hard disk BIOS vector which I need for the
SCSI card that's running the system.

I didn't want to remove it fully as I need to label the cables feeding it.
One feeds the top drive bays, and the other the bottom so if I ever need to
put it back it I need to know which is which. 

If I get some free time I will have a go at starting the disks in it and
repairing the RAID array, and perhaps copy the disks that are installed.

I gotta ask, what's the deal with the dangling card?  That cracked me up!

 

Thanks for posting some pics!

Well I found an XGA2 card in the pile of bits so now I have 1024x768 display
resolution. I have swapped the CDROM for a SCSI DVD drive. 

I managed to boot MTS and there are a few pics here:-
