[Info-vax] SET DEF and Other Questions Regarding DIR on a Different Hard Disk?

[haziz]

I am comfortable with Unix but am a complete newbie when it comes to VMS. I am trying to install OpenBSD on DKA300 on a VaxStation 4000 Model 90. I am logged in as SYSTEM on an OpenVMS 6.2 install on DKA0 and would like to figure out what is installed or present on DKA300, before formatting it to accomodate OpenBSD. DKA100 and DKA200 seem to have separate installs of OpenVMS 7.2 and 7.3 respectively. I would like to maintain the OpenVMS installs on the other drives since I may wish to eventually explore VMS.

SET DEF DKA300: followed by DIR gives an error message or does nothing (sorry I am not in front of the machine).

How do I explore the root directory on DKA300 and any subdirectories it has?

How do I figure out the free space on a drive?

I am using a VT520 terminal. How do I examine output that has scrolled by? Is there a pager program for VMS like less or more on Unix?

Is DKA300 definitely sd3 on OpenBSD, I would hate to format the wrong drive.

After briefly looking at the websites for NetBSD and OpenBSD on the Vax, OpenBSD looks more promising (easier install of more packages in what will be initially a non-networked machine). I am using a CDROM drive to perform the install.  Any reasons why to prefer NetBSD over OpenBSD on this system. I suspect that I will ultimately install both if I can figure out how to accomodate both on this machine without wiping the three OpenVMS installs already present. Each hard drive is 2.1 gigs.

I posted an earlier question on this newsgroup:

You may refer to my earlier question if you need some background as to what I am trying to do.

Thanks.
