This is somewhat related to my previous post. :-) I decided to try out the Adaptec Storage Manager utilities, even though they are from May 31, 2001 and seem to be for Red Hat 7.0/6.2 (the box I'm on is RH 8.0). I installed the rpm with rpm -ivh --nodeps since it wanted the dptdrivers RPM, but the dpt_i2o driver was already installed on my system. I started upt the dpt daemons -- no problems there. Also verified that the dpt_i2o driver was working: [root@pop adaptec]# cat /proc/scsi/dpt_i2o/0 Adaptec I2O RAID Driver Version: 2.4 Build 5 Vendor: Adaptec Model: 2100S FW:370F SCSI Host=scsi0 Control Node=/dev/dpti0 irq=11 post fifo size = 255 reply fifo size = 255 sg table size = 56 Devices: ADAPTEC RAID-5 Rev: 370F TID=519, (Channel=0, Target=0, Lun=0) (online) Looks good so far, right? Now I try: [root@pop adaptec]# /usr/dpt/raidutil -d 0 -L physical Engine connect failed: COMPATIBILITY number :-( Stumped here. Any suggestions? I tried without -d 0 and with -L array and simply got the same error. A google on the string brings up a few FreeBSD folks having the same issue which turned out to be shared memory related. No idea if this is the case on my system or not, or if it would even translate the same way between FreeBSD / Linux... - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
