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).

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?

[24 Mar 2022 Thursday] Erectile Dysfunction and Viagra

Image
Subject: [24 Mar 2022 Thursday] Erectile Dysfunction and Viagra I have erectile dysfunction due to taking medications for mental illness (schizophrenia). Without Viagra, my penis is soft like jelly most of the time. There is no way I can penetrate a woman’s vagina due to erectile dysfunction. Today is the very 1st time I am taking Viagra. It allows my penis to remain hard and fully erected for 2 solid hours during sexual intercourse. Thanks Viagra! I can finally have sex! I am already 44 years old. What am I missing out in life?????? Do I still qualify to be a Japanese Adult Video (JAV) porn star actor???????? Link:  https://m.facebook.com/story.php?story_fbid=10158113552827735&id=646397734
