Recently I asked a question and got some good tips on how to fix my problem from this group. I have another one for you. Our systems are set up as follows : Dec3100 Server (8mb), 3 Dec3110 Stations (8mb) TK50, 2 RZ55, RZ23 (in one of the clients). We are running ultrix. We recently set the systems up and I have yet to figure out how I can use the RZ23 on the client station. I want to use it as swap space but have no clue as to what to do first. I am short on disk space and have a 650MB disk we are going to order but I need to get the RZ23 in use now. Any assistance or direction would be helpful. Thanks.

We have been able to use successfully only one RZ23 per DS3100 and have significant space left on it. This was done essentially by NFS mounting /usr/etc, /usr/bin, /usr/lib, /usr/man, /usr/ucb from one NFS server. This has to be done carefully, since some of the programs in /etc which are links to ../usr/etc are needed at boot time. Anyway, our local /usr is down to 31 Mb (incl. var).

I am short on disk You first configure the system as a diskless node on your server. You then create a new configuration file for your client system and edit it, replacing the line in your config file of the format: config vmunxi root on qe0 with something like config vmunix root on qe0 swap on rz4b or whatever the device name of the local drive is. You also need to ensure that the disk controller and disk are also specified in the configuration file. This will allow you to use partition b of the local drive for paging and swapping. This wouldn't gain you a whole lot of disk space, but would obviously reduce the load on your server. The formal procedure is detailed in Chapter 4 of the Ultrix 3.0 Guide to Diskless Management Services; I would assume that 3.1 also supports this function. You could also probably copy a root partition onto partition a on the local drive and use /usr/mdec/installboot to make it bootable; your /usr partition would mounted via NFS from the server, and you would need a new kernel generated which configures vmunix to be on the local drive, something like: config vmunix root on rz4a swap on rz4b This would approximate the dataless client configuration available under SunOS. I've never done it on a DEC system, but I have for Sun 3's and 3-x's. You could then take partitions d-h and mount/use them locally or possibly export them (ugh) for the other systems to store data on. -- Larry Beaulieu The usual disclaimers apply.

Any assistance or direction would be helpful. If your short on disk space this probably won't help much be here goes: First you have to configure one of your machines as a server for diskless clients. This is done using dms, and the Ultrix server software (Ultrix 3.X) or your regular distribution tapes (Ultrix 4.0). The diskless environement takes about 68Mb with DECnet/Man pages, and some of the Unsupported stuff. After the server is configured, you can use dms to register a diskless client. One of the questions dms will ask pertains to where the client will swap, and do crash dumps. The client disk is one option, the server is the other. If you chose the client you will be prompted for the device name [ie rz3c] for the whole disk. If you want you can probably use chpt, change the partition sizes, and use some of the 104Mb for data. I use a 33Mb partition, (the default b partition) and should probably have made it larger. If you are already booting diskless, you should be able to edit the kernel config file and change the kernel definition to: >config vmunix root on boot swap on rz3c Hope this helps. -- Bob (Pete) St.Pierre University of Lowell Systems Manager 1 University Ave stpierre@ulowell.edu Lowell, Mass 01854 postmaster@ulowell.edu (508) 934-3645 Bob (Pete) St.Pierre University of Lowell Systems Manager 1 University Ave stpierre@ulowell.edu Lowell, Mass 01854 postmaster@ulowell.edu (508) 934-3645

Does this mean all server software is included in the Ultrix 4.0 release and you do not have to buy an Ultrix Server kit to be a diskless server? I was just configuring my DS3100 running Ultrix 3.1 to be a server and found out I have to get a server license and a server software kit. If Ultrix 4.0 has all this included I will be better off just getting Ultrix 4.0. Thanks in advance. Chris Martel Clearpoint Research Corp.

The Ultrix server kit is included in some of the pre-configured 5800 and perhaps 5400 system configurations. I don't know if 4.0 changes this one way or the other. -- George Robbins - now working for, uucp: {uunet|pyramid|rutgers}!cbmvax!grr but no way officially representing: domain: grr@cbmvax.commodore.com Commodore, Engineering Department phone: 215-431-9349 (only by moonlite)
