- Before ULTRIX V4 supported disks were known by the installation procedure
- since some geometry information was desired by the mkfs(8) used to create
- the initial root file system. Starting in V4, a new I/O control was added,
- DEVGETGEOM, that would allow a program to query a disk for it's geometry.
- The installation procedure was modified to use this I/O control to get
- the information.
-
- Some disks put their geometry information in the places that the ULTRIX
- drivers expect and you can perform an installation using these disks.
- Other disks don't put their geometry inforation in the expected place
- and the installation fails. The message you're getting is the symtom
- of this problem. The solutions are:
-
- 1. Once the standalone system is loaded, use the System Management
- option and edit the appropriate installation script so that it
- doesn't try to ask the disks it's geometry and uses one you give
- it instead. The script to modify is install.1.
-
- It's worth noting that if the early part of the installation
- doesn't recognize the disk and can't get the geometry the later
- part of the installation that creates the /usr (and /var) file
- system(s) won't work either.
-
- 2. Do enough installation on a supported disk to get a working system
- up and then move what file system you want on the other disk to
- that disk.
