Any chance of an HP AutoRAID array working?
Hello PA-people,
Today I purchased 2 K370s and a K570 for roughly US$75 ($25 each). All of the machines have 4 internal disks: 4, 4, 9, and 9 GB.
However, one K370 and the K570 have each got a disk array in them, full of 18GB disks, and sporting a fancy LCD display. These arrays take up roughly half a rack each, and are labelled "HP AutoRAID".
The boxes have HPUX-10.20 on them, and SAM identifies the AutoRAID unit as a single logical drive (with extra goodies such as the power and fan status, etc. Nice.) Each array is connected to its server via a large HSC board with what appears to be several differential SCSI cables.
I'm keen to use Linux (probably Gentoo but Debian's also fine) on these boxes, but I'm wondering if that'll mean I'll have to forfeit the 8 x 18G disks in each array, which would be a pity...
I don't need to know the PSU and fan statuses, I just want the space. If necessary, I can dedicate one of the 4 internal disks to HPUX, just in case I need to reconfigure the RAID system.
Has anyone tried Linux on one of these AutoRAID systems? A brief spin though Google didn't reveal anything. It also didn't reveal a manual on how to configure the arrays, so any pointers to *that* would also be useful.
Also, I presume that I can strip two of the machines to fill up the remaining machine with RAM and CPUs; the HWDB seems to suggest that multiple processors will work OK under recent kernels. Right?
Thanks,
Andrew

No. Those are standard SCSI LUNs. use the LCD panel to config the LUNs and the AutoRAID will arrange for shifting data from RAID 1 to RAID 5 as it sees fit.

At one point i did. I haven't in a long time though.

In general, SMP is working.
AFAIK, K-class only had issues with console support and some recent issues with GSC 53c720 support. I've forgotten details. :(
