CISS Smart array controller error.

[bhragha]

on rx4640 machine I am getting below error while booting.

========================================
CISS: Raid SA controller on hardware part 0/1/1/0/4/0 has detected fetal IO.

logical block add -0
Logical block count 16
Logical command 0x20
Fetal Drive Bus 1
Fetal Drive ID 0
==========================================
I have two hard disk when I boot with "boot -lm" ( LVM maintenance) I am able to go to single user mode and able to activate all the VG and mount LV's. After mounting all partition I tried to execute below commands but I got same error and not getting prompt back.

===========================
sautil /dev/ciss2
saconfig /dev/ciss2 -F off
================================

I am having data on this disk so I don't want to take risk by clearing SA configurations please help. How to resolve this?

Looks like you have a problem with a drive.

Can you access ORCA (press ESC followed by 8 during boot) and check the status from there?

Hi I am able to access ORCA (Option Rom Configuration for Arrays). And I can select all the options and I have seen "view logical Drive" it is showing good.

And also I am able to boot with option "boot -lm" and there I activated vg00, vg01 and mounted all logical partition its fine I am able to access. But normal boot is not happening.

IMHO 1 out of the 2 drives is blocking everything. Most likely the lower disk.

I would try to power off the server, remove this disk and power on again. Ignore the message regarding a missing drive, the server should start. If not successful, power off again and try the other drive.

I tried to boot removing one disk after another, but I am getting error "boot disk failure" . I followed below steps.

a.) I booted system in LVM maintenance (boot -lm) mode and ran command "setboot -p /dev/disk/disk3 -b on" -- Disk which is having SCSI ID 0(lower disk )

b.) No alternate boot path set
c.) Edited /etc/lvmrc to activate only /dev/vg00
d.) rebooted the system by removing one hard disk i.e SCSI ID 1. But I am getting error "boot disk failure"..

I assumed your boot disk is on this array controller. Now I doubt.
Is it?

[bhragha]

Yes both disks are on "Smart Array controller" only.

But my doubt is if it is a problem with Array controller why it is booting in "boot -lm" . And I am able to mount all the disks there. If I am booting system normally this error is coming.. !!

Strange.

What firmware is on the controller (you see this during boot)?

HP Smart Array 6400-128 Controller (version 2.84) 1 Logical Drive
Press to run the Option ROM Configuration for Arrays Utility

3.17 is the firmware version.

And Smart Array controller is 6400-128 (version 2.34)
