>********************************
>I'm trying to upgrade Alpha Station 255 from DU 3.2D-1 to DU 4.0D. I arranged
>installation media also for DU 4.0 and DU 4.0A. I successfully upgraded
>firmware. When trying to upgrade to 4.0, installation procedure responsed
>with the message regarding not enough space on the root partition. I tryed to
>remove all unnecessary files, but the message remains.

>The size of root partition is 64 Mb and it is probably not enough for upgrade
>to 4.0D.
>
>I do not have much experiences with administrating DU, but with help of
>manuals I found out, that there is probably one unused partition of 800 Mb on
>the hard disk which can be used as root partition.
>
>Please, give me some advice, how to transfer root partition to this unused
>part of the disk.

>All replayers recommended me not to transfer the root partition, but to

>Creating a larger / partition by Karen Byrd.

>Don't bother trying to move it. Moving the root away from
>the first partition of the disk is probably little tested
>and may not work. What you need to is:
>
>a. Get a 2nd disk, partition it for the root to have more
> space and migrate the existing root to that.
>
>b. Backup the existing root, make the partition larger and
> restore.

>Since B will cut into the primary page/swap space, you'll
>want to move each file system, to grow the others. Fortunately
>you have that H space available for growth.
>
>FIrst figure out how you want to repartition. V4 is using
>128 MB for the root file system, so you at least want to
>grow the A partition by 64 MB. That means changing the
>offset of B. You may also want to grow it while you're
>there. This in turn affects there G starts, which means
>using H.
>
>So, shutdown to single user, and get a backup of all the
>file systems on the affected disk. Use vdump. Remove
>the file set and domain for /usr and repartition G and H
>so that you have room to move B. Use the disklabel command
>with the -e option. Once G and H are repartitioned, recreate
>the domain and usr fileset and restore. To do the root
>you'll need to boot from the CDROM.
>
>The procedure here is basically the same, only your using the
>standalone system.

>********************************
>Your best course of action is to backup all files from the old OS 3.2
>(perhaps DAT, CD-R or another disk). Ensure that you have upgraded the
>firmware (which you mentioned that you have) and then install DU V4.0D
>from scratch so you can resize your / (root) to 128Mb and /usr to 700Mb
>(approx). To boot from CD following steps:
>
>(DU 3.2)
>
># /sbin/shutdown -h now
>
>(it will then drop down to the SRM console)
>
>>>> show dev
>
>(will inform you of your devices)
>
>>>> boot dka400
>
>(if you CD is device dka400)
>
>This will then boot from CD and then you'll be presented with various
>option such as; system information, software selection and most
>importantly (for you) partition disk.
>
>Good luck and I hope this helps.

>When I upgraded to 4.0d, I had to increase my / partition to 128mb's.
>Seeing as you're going to have to do this anyway I'd have to recommend
>that you do it sooner rather than later.
>
>It's easy to do. First, dump your / and /usr file systems onto
>separate tapes(I'm assuming that these are the two file systems on the
>slices indicated below.) Once you have your root disk backed up, you
>will have to boot off CDROM in order to edit your disk label. Edit your
>disk label to reflect the new partition sizes and write it to disk.
>Remember that writing the disk label will blow away everything on your
>disk! Create new file systems on the new partitions and you are ready
>to go.
>
>With the new label written and the new file systems created you can
>restore the O/S to the newly sized / partition.
>
>I used this method when I upgraded from 4.0b to 4.0d and it worked
>great! I've never had a smoother UNIX upgrade; I felt truly blessed.

>You can not use partition h as a root partition. You must change all

>One way.
> Do a / and /usr backup (vdump)
> Boot with cd
> Change yours partition a, b and g overwriting partition h (disklabel
>-e using vi as editor)
> Restore / and /usr (vrestore)
> Boot as usually.
> Do an upgrade without problem.
>This procedure will take no more than 2 hours because you have a 2 GB disk
