Subject: arcconf Linux utility for Adaptec AAC-RAID (Rocket) (rev 02) (IBM ServeRAID 8k/8k-l8) unable to query RAID controller

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.

[root@teo-en-ming-server ~]# fdisk /dev/sda

We rebooted the server several times. The next morning we still get the same error messages.

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@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@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@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?
