Greetings,
I am running a 3ware 9500 SATA raid card in a 12x300GB raid 50
configuration. Too often, I am seeing reboots during high I/O (rsync)
operations.
drue at leopard:~$ uname -a
FreeBSD leopard.claimlynx.com 5.4-SECURITY FreeBSD 5.4-SECURITY #0: Thu
Jun 30 02:25:52 UTC 2005
root at builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC i386
This is logged in /var/log/messages just before the reboot:
Oct 1 23:15:49 leopard kernel: twa0: Missing expected status bit(s) 2000<MC_RDY>
Oct 1 23:15:49 leopard kernel: twa0: SCSI cmd = 0x2a: ERROR: (0x03:0x0001)
Oct 1 23:15:49 leopard last message repeated 239 times
Oct 1 23:15:50 leopard kernel: a: ERROR: (0x03: 0x0001)
Oct 1 23:15:50 leopard kernel: twa0: SCSI cmd = 0x2a: ERROR: (0x03:0x0001)
Here is dmesg identifying the controller:
3ware device driver for 9000 series storage controllers, version: 2.50.02.012
twa0: <3ware 9000 series Storage Controller> port 0xb800-0xb8ff mem 0xfb800000-0xfbffffff,0xfc5ffc00-0xfc5ffcff irq 24 at device 2.0 on pci2
twa0: 12 ports, Firmware FE9X 2.06.00.009, BIOS BE9X 2.03.01.051
Is this somethign that has been worked on in 5-STABLE or 6? Would
a kernel dump be helpful? Please aim me at the appropriate list or
people that would know.
Thanks,
Dan
