Hello, I am having some problems with my DAC960PG. Here is part of dmesg: DAC960: ***** DAC960 RAID Driver Version 2.2.4 of 23 August 1999 ***** DAC960: Copyright 1998-1999 by Leonard N. Zubkoff <[EMAIL PROTECTED]> DAC960#0: Configuring Mylex DAC960PG PCI RAID Controller DAC960#0: Firmware Version: 4.06-0-08, Channels: 2, Memory Size: 4MB DAC960#0: PCI Bus: 0, Device: 19, Function: 1, I/O Address: Unassigned DAC960#0: PCI Address: 0xFD8FE000 mapped at 0xD8800000, IRQ Channel: 19 DAC960#0: Controller Queue Depth: 64, Maximum Blocks per Command: 1024 DAC960#0: Driver Queue Depth: 63, Maximum Scatter/Gather Segments: 33 DAC960#0: Stripe Size: 64KB, Segment Size: 64KB, BIOS Geometry: 255/63 DAC960#0: Physical Devices: DAC960#0: 0:0 Vendor: QUANTUM Model: VIKING 4.5 WSE Revision: 887R DAC960#0: Serial Number: 174727535051 DAC960#0: Disk Status: Online, 8898560 blocks DAC960#0: 0:3 Vendor: QUANTUM Model: VIKING II 9.1WSE Revision: 5520 DAC960#0: Serial Number: 199830743205 DAC960#0: Disk Status: Online, 17836032 blocks DAC960#0: 1:2 Vendor: IBM Model: DGHS18V Revision: 03E0 DAC960#0: Serial Number: 68087EC9GK DAC960#0: Disk Status: Online, 35842048 blocks DAC960#0: 1:3 Vendor: IBM Model: DGHS18U Revision: 03E0 DAC960#0: Serial Number: 68111A0CGK DAC960#0: Disk Status: Online, 35842048 blocks DAC960#0: Logical Drives: DAC960#0: /dev/rd/c0d0: RAID-7, Online, 8898560 blocks, Write Back DAC960#0: /dev/rd/c0d1: RAID-7, Online, 17836032 blocks, Write Back DAC960#0: /dev/rd/c0d2: RAID-0, Online, 71684096 blocks, Write Back The first problem I have is that when I reboot the drives I have previously configured and used show up as having an invalid partition table. I tried swapping controllers and get the same result. The controller I am using now just came back from RMA. debian:/home/andy# fdisk /dev/rd/c0d0 Device contains neither a valid DOS partition table, nor Sun disklabel Building a new DOS disklabel. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable. Command (m for help): p Disk /dev/rd/c0d0: 255 heads, 63 sectors, 553 cylinders Units = cylinders of 16065 * 512 bytes Device Boot Start End Blocks Id System Command (m for help): Secondly, I can initialize the Viking II from within daccf, and check it for errors, but when I reboot the drive is always marked as dead. If I remove the drive and put it in another machine it will format and work properly. DAC960#0: Irrecoverable Data Error on READ: DAC960#0: /dev/rd/c0d1: absolute blocks 0..1 Thanks, -Andy
