Integrated Smart Array Controller (ROC): Even though the ROC supports raid on one channel and a tape drive on the other, the driver in linux (cpqarray) does not yet support tape drives. In a system with a ROC chip where you want to perform raid on hard drives and also have a tape backup, there are two solutions:
The PL4500 is a unique box. It seems to be the only one that has the NCR53c825 chipset and be entirely EISA based (no PCI slots). As far as I can tell (I am currently checking into this 7/8/00) the NCR53c8xx driver does not support EISA. I cannot find a way to pass the io_port nor irq to the driver so it can find the board (EISA is not easily detected by drivers, most of the time it is required to pass the io_port and sometimes the irq). The only solution at the current time is to install a Linux supported controller board. A couple of choices of Linux compatable boards are as follows:
RA8000: There is current support, see ra.html. RA4000/RA4100: You can use the cpqfc driver, which has been released and is in Red Hat 7.0. It only supports one card: the 64-bit/66MHz Fibre Channel Host Adapter. This information is on the Options Support Matrix, at: http://www.compaq.com/products/servers/linux/OptionsMatrix.html Here's the FreshMeat page for this driver: http://freshmeat.net/projects/cpqfc/ When using this driver, your arrays will be accessed through the standard SCSI devices, such as /dev/sda, /dev/sdb, etc. This is different from our other array controllers which use their own device names (like /dev/ida/c0d0, etc.).
