Does anyone know what kind of hard drive is in the 9133 hard drive systems and can they be upgraded from the little 14.5M to something in the 20-40M range w/o any changes to HPUX?

re: "...what kind of hard drive is in the 9133 hard drive systems..." Which 9133?, The 9133A, B, D, H, L, V or XV? Look on the back. All varieties of 9133 used Seagate mechs of one kind of another. > ...and can they be upgraded from the little 14.5M to something in the 20-40M > range ... It sounds like you have either a 9133XV or a 9133D. The 'XV cannot be upgraded. The 9133D would require at least firmware changes and perhaps a new SS/80 controller board. Even if you could get the needed information (and I don't have it), only specific models of Seagate mech could be used and they are all probably obsolete, which is part of the reason why the 9133-series is no longer made. > ... w/o any changes to HPUX? SS/80 drives are fully parametric, so if you could upgrade a 9133D to a 9133H (20M) or 9133L (40M), HP-UX would recognize it.

The HP9133 drives CAN be upgraded. I have 3 of them that I have upgraded to 40 Mbytes each. You need to replace the old hard drive mechanism with a Seagate ST-4051 and change a jumper on the controller board. Two of the drives I had used Seagate ST-419 and ST-225 drives. These are the ones I upgraded. Be careful to record the existing jumper settings BEFORE changing them in case you have trouble with the upgrade. For a rev B controller board, set the jumpers to EBxH. For a rev C controller board, set the jumpers to EBxD. 'x' indicates leaving that jumper unchanged as that jumper tells the controller if a floppy drive is present and should not be changed. Also note the jumper that says 256/1024. That affects the physical sector size of the hard disk. Changing it to 1024 bytes/sector will increase the amount of storage available. If you store a lot of small files (<1024 bytes) this may not be a good idea as it will actually waste space. I use these drives with an HP PACAL workstation and have had no problems. They should also work with any HP system as this upgrade converts the drive to a 9133L which should be supported. Feel free to email any questions. Don Novy Hewlett-Packard den@hpfijbj.hp.com
