Does anyone have a copy of the configuration software and instructions for configuring this RAID disk controller on an Alphaserver (2100 4/233) for running OpenVMS? I have been looking around, but the specific steps and settings for setting it up on Alpha seem to be scattered across several guides. I would like something like a step by step on how to setup a simple RAID 0+1 setup.
Going strictly from memory, that sounds like a SWXCR variant of a MYLEX controller.
It takes booting a floppy or CD-ROM with the configuration utility on the Alpha. I think they used to be downloadable. I do not know anymore.
Someone on comp.os.vms may be able to provide you with a bootable image offline, or when Encompasserve get back up, you can ask there, since I think Encompasserve has that hardware installed.
However, you can put the card in a X86 based PC and during the boot sequence it should allow you to press a key sequence to go into a ROM based configuration utility. That utility should be able to allow you to configure the disks anyway that you want.
There is a limitation in the firmware on the Alpha variant of the card on the size of the volumes that the SWXCR can present to the operating system.
This has interpreted as a limitation of the size of the physical disks you can use. From personal experimentation, you can use the larger physical disks (still small by today's standards), just make sure that the final volumes do not exceed the max.
Make sure that the SWXCR card is always powered off before the Disks that are connected to it. Otherwise it will mark them all as failed. Then you have to boot the configuration utility and mark them fixed and do an ANAL/DISK/REPAIR after booting VMS to fix.
