Good day from Singapore,

Our client has IBM System x3650 server (machine type: 7979). Operating
system is CentOS Linux 6.10 (32-bit).

Recently we keep getting the following error messages (output
generated by dmesg).

/dev/sda is a RAID 5 array with 3 harddisks of 136.6 GB capacity each.

Based on the following discussion thread, we think that the RAID
controller may be failing.

Discussion thread: Which disk is bad in raid6 array
Link: https://serverfault.com/questions/384935/which-disk-is-bad-in-raid6-array

I had downloaded 32-bit arcconf Linux utility from the following link.

Link: https://hwraid.le-vert.net/wiki/Adaptec

<CODE>

[root at teo-en-ming-server log]# lspci -vvv | grep RAID
04:00.0 RAID bus controller: Adaptec AAC-RAID (Rocket) (rev 02)
        Subsystem: IBM ServeRAID 8k/8k-l8

</CODE>

However, we keep getting segmentation fault running arcconf utility.

<CODE>

[root at teo-en-ming-server log]# /usr/local/sbin/arcconf getconfig 1
Segmentation fault (core dumped)

</CODE>

These are the Linux Kernel messages.

<CODE>

</CODE>

It seems that I could not query the RAID controller. It keeps saying
that the RAID controller adapter has kernel panics.

arcconf is a Linux utility to query the RAID controller.

<CODE>

[root at teo-en-ming-server cmdline]# lspci -nn | grep RAID
04:00.0 RAID bus controller [0104]: Adaptec AAC-RAID (Rocket)
[9005:0286] (rev 02)

</CODE>

Do you know why I keep getting segmentation fault running arcconf Linux utility?

The page says "It seems that some version works with some adapters some
won't."

What you need for this ancient machine and RAID controller is arcconf version
9.30. It is quite hard to come by these days. Ideally, you'd want
ibm_sw_srapp_9.30-17006_anyos_32-64.iso, which also includes RaidMan, but this
download has been removed.

Try this one:
