You are probably already aware of this, and they probably are not be any easier to find now than an R80, but an RM80 will work fine off of the RB730 controller.
My first home machine was an 11/725, to which I added an RB730 controller , and I used it with an RM80 for a number of years, until power problems killed a bunch of boards in it. I hated losing it, since I had also added a VAXstation 100 workstation peripheral to it - at the time it was a pretty exotic setup for use at home. I'm still hanging on tothe VS100 gear, in case another Unibus VAX comes my way.

Unibus to SCSI is probably your best bet.

These are available on eBay for about a $1K last I looked. You'll need to poke around the VMS web sites for the drivers, but we had some of these on a couple Unibus machines, including a 780 a >>long<< time ago. I know no reason why it would work for a 730 - although you might need to sysgen on a working system to create the boot disk.

I have several vintage SMD drives, including a couple of nice CDC 9715 drives, that I was thinking about using to replace the RA8x drives. I have not one but two UNIBUS SMD controllers an Emulex SC21 and a Spectra Logic 121 that I thought would do the job, but after reading the fine print yesterday that turns out not to be true. Both controllers emulate RH11s with RM0x drives attached, which is fine if you re a PDP-11 but VMS has never supported that configuration.
[Before anybody says Wait RM05s are supported by VMS, that s only partly true. VMS supported MASSBUS disks on a RH750 or RH780 controller, but VMS has never supported the RH11. Emulex actually sold a special VMS driver for their card, but I don t have it and besides, VMB still wouldn t support it. The Spectra Logic manual only talks about PDP-11 OSes and carefully avoids ever mentioning VMS.]
I ve got some RA7x drives, but there s no easy way to mount them or supply power to them. I m not sure if there ever was a rack mount chassis for RA7x drives. There was for RA9x drives, but those I don t have. I also have two RC25 drives and several AZTEC controllers, but those drives were horribly unreliable even when they were new. Neither works, and fixing them or getting removable media for them is hopeless.
Does anybody have any other ideas? Who else has an old UNIBUS VAX? What are you doing to disk drives?
I ve actually had the 11/730 for about fifteen years now I restored it out of parts from two different 730s that were scrapped. It s been fairly easy to keep running except for the drives, and although it s admittedly a bit slow, it s a cool machine.

Well I suppose I could try to find one - could roll out a Netware VM + NEXTSTEP does Netware file sharing..

I have an IPX network partially up at the moment. Is there any OpenVMS IPX support? There's SNA integration so I don't see why DEC wouldn't let Novell be unsupported. ;)
Sampsa, you could join easily if you pick up a low-power older cisco router for absurdly cheap if you don't care about speed. (like a 2524...10BASE-T! It'd be perfect for IPX and low-bandwidth DECnet tunnels!)

There are some of you who may have noticed the tunnel system trying to update my tunnel with a source IP of nothing.
I've fixed the script which populates the db with my home IP address so that will not happen again.
I also added data sanity checking code to the tunnel config system to better deal with this sort of thing in the future. A blank IP would actually cause the pySNMP module to explode into flames and bring the entire thing down. :)

Should work. You might possibly want to mount the devices foreign, but otherwise you should be good.
I've never had to use the /DEVICE switch. It works correctly by default.
You might like using the /STATUS switch, to see the progress.
I think I'll go crank up the 730 to copy the RL02...
:-)
Sadly the 730 doesn't boot. I was afraid it wouldn't - the RA81 is being
cranky. "Servo fine positioning error" (which probably means "the HDA is
trash"!) Those things are not particularly reliable, but there aren't many
alternatives for disk drives.
Check that the transport lock isn't engaged.

I need some modifications made, please.
Change the source int for the tunnels to Dialer0 and set the hostname you
use to dev.gimme-sympathy.org. I intend to switch to a static plan soon.
( My edge is currently a 3745 and I haven't quite figured out NAT and port
access so it may not be allowing SNMP in. ;) )
Thanks!
