What are the solutions for replacing our 4GB internal LDEV1 with something that supports RAID -- or at least disk mirroring? We currently have our production data in 'Jamaica' units, fully mirrored (Mirror/iX), but I've been worried about that ancient LDEV1. We do everything possible to not shut down power. It has reached the point where I have concern that if the drive ever lost its taste for power, it might never spin up again -- and the thought of a RELOAD is not fun.
There are two fairly low cost solutions which could handle RAID for your 3000. These would be the Mod 10/20 (at left) and Autoraid 12H units, both of which connect via FWD SCSI. A Mod 10/20 would require two FWD cards/connections to be available; the 12H, just one.
Gilles Schipper says
If the HP 3000 is not an A-Class or N-Class, then the best solution would be a Mod 10/20 or an Autoraid 12H. If it is an A-Class or N-Class, the best solutions include any number of fiber-capable devices -- such as a VA7xxx, an XP unit, and others. You could use the Mod 10/20 and Autoraid, but why would you, unless cost is the most important factor?
Craig Lalley says
One problem to consider is the model of HP 3000. The older "NIO" backplanes used in the 9x9s and earlier do not support native Fibre Channel. The N-class boxes do. To boot from a VA7xxx array, you would need the A5814A-003 Fibre to SCSI "brick" if you are not using an A-Class or N-Class.
We have recently begun our migration off the HP 3000. How can I determine what programs reference the data items in our TurboIMAGE databases, since the application vendor we currently use did not provide us with a data dictionary?
Since you're using COBOL and probably use copy libraries, you could use Robot/3000 from Productive Software Systems. (Screen shot of Robot shown at left)
Larry Simonsen adds
Another option is to use the 3000's grep command in MPE/iX.
