iLO 4 Embedded Flash/SD-CARD Embedded media manager failed media attach

iLO 4 was presenting the message: Embedded Flash/SD-CARD Embedded media manager failed media attach.

I’ve updated iLO 4 to v 2.70 and then performed the following procedure

Advisory: (Revision) HPE Integrated Lights-Out 4 (iLO 4) – How to Format the NAND Used to Store AHS logs, OneView Profiles, and Intelligent Provisioning

Created a file Force_Format.xml

root@linux:~ # vi Force_Format.xml

<LOGIN USER_LOGIN=”adminname” PASSWORD=”password”>
<RIB_INFO MODE=”write”>
<FORCE_FORMAT VALUE=”all”/>
</RIB_INFO>

Run hponcfg -f Force_Format.xml

Script succeeded

Then I reset ILO through the web interface

samba rebased to version 4.6.2

To improve security, the NT LAN manager version 1 (NTLMv1) protocol is now disabled by default. If you require the insecure NTLMv1 protocol, set the ntlm auth parameter in the /etc/samba/smb.conf file to yes.

The storage was upgraded so my RHEL 7.5 server is the client trying to connect to the Windows share. It is showing the message protocol negotiation failed: NT_STATUS_CONNECTION_DISCONNECTED

root@linux:~ # smbclient //storageserver/PUBLICO -U “setaoffice/username%PASSWORD” -c ‘prompt; cd CC_EFC_Inbound/Logs; mget *.log’
protocol negotiation failed: NT_STATUS_CONNECTION_DISCONNECTED

To solve the problem, I had to add -m SMB2 or -m SMB3 to the smbclient

root@linux:~ # smbclient //storageserver/PUBLICO -U “setaoffice/username%PASSWORD” -m SMB2 -c ‘prompt; cd CC_EFC_Inbound/Logs; mget *.log’
Kinit for username@SETAOFFICE to access storageserver failed: Cannot find KDC for requested realm

RHEL 6 server receiving error mounting CIFS (Windows) share – mount error(112): Host is down

When mounting a CIFS (Windows) share, I’m receiving an error saying the host is down

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

This is the share in /etc/fstab

This problem happened because the storage was upgraded and it is using SMB2. You need to have at least kernel 3.7 to have support for SMB2
SMB shares fail to mount with the SMB2 protocol

First of all, the problem is that you are stuck at the boot sequencing.

The boot sequencing method is decided during installation or upgrades. If there are no loops in the dependencies declared by the LSB headers of all installed init.d scripts and no obsolete scripts, the system is converted to dependency based boot sequence.

We have to check for

1. Loop in dependencies: Occurs when >
• There are missing LSB tags in some scripts or error in LSB tags like missing Required-Start: or Required-Stop: tags

• Some scripts depend on other scripts which depend on the system facility $all which cannot be true. Because the scripts depending on $all is loaded last at starting. Since it loads last, nothing can depend on it. Hence, messes up the dependency based boot sequence.

2. Obsolete scripts: Occur when

• Some packages being upgraded to newer versions which may not use a script in /etc/init.d/ and the maintainer may have missed the code to remove the old script. Not our mistake.

I edited file /etc/init.d/esmrc and added a LSB header after #!/bin/sh

root@linux:~ # vi /etc/init.d/esmrc
#!/bin/sh
### BEGIN INIT INFO
# Provides: esmrc
# Required-Start:

Linux LVM: File-based locking initialisation failed

Running a lvm command and you encounter the message File-based locking initialisation failed means that the filesystem is read-only

root@linux:~ # pvs
File-based locking initialisation failed

The directory /var/lock/lvm must be writable. So you have a /var or / filesystem read-only.

You can try to remount it as read-write or reboot the server

mount -o remount,rw /
reboot -d -n -f

Source: Running an LVM command returns “File-based locking initialisation failed” or “Locking type 1 initialisation failed”

Linux – shutdown: Unable to shutdown system

Booted the system adding init=/bin/bash at the end of the kernel line.

Entered Rescue system

Now when trying to restart the system, it appears the message shutdown: Unable to shutdown system

bash-4.1# shutdown -r now
shutdown: Unable to shutdown system
bash-4.1# reboot
shutdown: Unable to shutdown system

To reboot the server, you need to use the following command

bash-4.1# reboot -n -d -f

After update to SUSE Linux 11 SP4, it stuck on a black screen written grub>

After updating a Suse Linux 11 to SP4, I’ve booted the server and it was stuck on a black screen written grub>

To solve this problem it is needed to:
Boot using a Suse Linux 11 DVD
Select Rescue System
Choose a language
Login as root

# grub
find /boot/grub/stage1
root (hd0,0) -> type according to your system, found using find /boot/grub/stage1
setup (hd0)
quit

Reboot the server
reboot -d -n -f
